    Before:       POOLER and MENASHI, Circuit Judges, and VYSKOCIL,
    District Judge. †
    The plaintiffs-appellants and cross-appellees are participants in
    the physical and derivatives markets for platinum and palladium and
    seek monetary and injunctive relief for violations of the antitrust laws
    and the Commodities Exchange Act (“CEA”). According to the
    plaintiffs-appellants, the defendants—mostly foreign companies
    engaged in trading these metals—manipulated the benchmark prices
    for platinum and palladium by collusively trading on the futures
    market to depress the price of these metals and by abusing the process
    for setting the benchmark prices. The defendants allegedly benefited
    from this conduct via trading in the physical markets and holding
    short positions in the futures market. The district court held that it
    had personal jurisdiction over two of the foreign defendants, but it
    dismissed the plaintiffs’ antitrust claims for lack of antitrust standing
    and   the    plaintiffs’   CEA    claims   for   being    impermissibly
    extraterritorial. The plaintiffs appeal the dismissal of these claims. The

    defendants cross-appeal the district court’s holdings on personal
    jurisdiction.
    We reverse in part, vacate in part, and affirm in part. We
    reverse the district court’s holding that Larry Hollin and White Oak
    Fund LP (the “Exchange Plaintiffs”) lacked antitrust standing to sue
    for the manipulation of the New York Mercantile Exchange futures
    market in platinum and palladium. As traders in that market, the
    Exchange Plaintiffs are the most efficient enforcers of the antitrust
    laws for that injury. But we affirm the district court’s conclusion that
    KPFF Investment, Inc. did not have antitrust standing. Additionally,
    we vacate the district court’s dismissal of the plaintiffs’ CEA claims.
    The plaintiffs have alleged sufficient domestic activity so that the CEA
    claims are not impermissibly extraterritorial. We affirm the district
    court’s holdings as to personal jurisdiction over the foreign
    defendants under a conspiracy theory of personal jurisdiction.

    MENASHI, Circuit Judge:
    The plaintiffs-appellants and cross-appellees in this case
    participate in the markets for physical platinum and palladium and
    for derivatives in those commodities. The plaintiffs-appellants
    brought lawsuits alleging that the defendants—companies engaged
    in precious metals trading—conspired to manipulate the global
    benchmarks for those metals. Most, but not all, of the defendants are
    foreign.
    The plaintiffs sued for violations of the antitrust laws and the
    Commodities Exchange Act (“CEA”) and for unjust enrichment.
    According to the plaintiffs, the defendants artificially depressed the
    4
    benchmark prices for platinum and palladium both by collusively
    trading in those metals’ derivatives—and thereby affecting the price
    of platinum and palladium generally—and by manipulating the
    process of setting the benchmark price. The defendants allegedly
    benefited from these actions by participating in the physical market
    for platinum and palladium and by holding short positions in the
    futures market. The plaintiffs, as sellers of platinum and palladium
    and participants in the derivatives market, allege corresponding
    injuries.
    The changing legal landscape since the initial filing resulted in
    multiple complaints from the plaintiffs and multiple dispositions
    from the district court. Ultimately, the district court concluded that it
    had personal jurisdiction over two of the foreign defendants under a
    conspiracy theory of personal jurisdiction, but it dismissed the
    antitrust and CEA claims. It determined that the plaintiffs were not
    efficient enforcers of the antitrust laws—and therefore lacked
    antitrust standing—and that the plaintiffs’ CEA claims were
    impermissibly extraterritorial. The plaintiffs timely appealed, and the
    foreign defendants over whom the district court held that it had
    personal jurisdiction cross-appealed that issue.
    We reverse in part, vacate in part, and affirm in part. KPFF
    Investment, Inc. lacked antitrust standing to sue for the impact that
    the defendants had on the physical platinum and palladium market.
    However, those plaintiffs who participated in the futures market—
    Larry Hollin and White Oak Fund LP—are the most efficient
    enforcers of the alleged antitrust injury in that market and have
    antitrust standing to pursue claims based on that injury. We also hold
    that the plaintiffs have alleged sufficient domestic activity to survive
    5
    a motion to dismiss on the CEA claims. And we affirm the district
    court’s exercise of personal jurisdiction over the foreign defendants.
    BACKGROUND
    In considering this appeal, we “accept[] as true all factual
    claims in the complaint and draw[] all reasonable inferences in the
    plaintiff’s favor.” Henry v. County of Nassau, 
    6 F.4th 324
    , 328 (2d Cir.
    2021) (quoting Fink v. Time Warner Cable, 
    714 F.3d 739
    , 740-41 (2d Cir.
    2013)).
    I
    Platinum and palladium, members of the same element family,
    are versatile metals. The metals are used in “catalytic converters,
    laboratory equipment, electrodes, and dentistry equipment.” App’x
    372 (footnote omitted). Besides these industrial applications,
    platinum and palladium are used in jewelry and are traded by
    investors. In 2013 alone, the gross demand for platinum and
    palladium was over 8 million and 9.6 million ounces, respectively.
    Aside from the traditional physical market, the metals are also
    traded in futures and options markets, especially on the New York
    Mercantile Exchange (“NYMEX”), “the leading centralized exchange
    for platinum and palladium futures and options worldwide.” Id. at
    381. On the NYMEX, “futures are standardized contracts that call for
    the delivery of physical platinum or palladium … on a specified
    date.” Id. In contrast to transactions involving physical metal, which
    “are done between private parties,” the NYMEX “is the counterparty
    to all transactions on the exchange” through “its clearinghouse, CME
    Clearing.” Id. at 381. By “simultaneously buying and selling the
    contract,” a clearinghouse “guarantees both sides of the trade and
    6
    ensures that neither buyer nor seller is exposed to any counterparty
    credit risk.” In re Amaranth Nat. Gas Commodities Litig., 
    730 F.3d 170
    ,
    174 (2d Cir. 2013). Since 2011, the aggregate annual value of platinum
    and palladium futures has surpassed $100 billion and $40 billion,
    respectively.
    The defendants include BASF Metals Ltd. (“BASF Metals”),
    Goldman Sachs International (“Goldman Sachs”), HSBC Bank USA,
    N.A. (“HSBC”), and ICBC Standard Bank PLC (“ICBC”) (collectively,
    the “Fixing Members”). BASF Metals is a company organized under
    the laws of the United Kingdom with its principal place of business
    in London, England, that engages in “precious metals commodity
    dealing.” App’x 363. Goldman Sachs, HSBC, and ICBC are financial
    services companies and, according to the plaintiffs, each company
    “holds substantial market share in Physical and NYMEX Platinum
    and Palladium.” Id. at 366-68. The three financial services companies
    each conduct proprietary trading and also execute client trades.
    HSBC’s principal place of business is in McLean, Virginia; Goldman
    Sachs’s and ICBC’s principal places of business are in London,
    England.
    Between 2008 and 2014, there was a formal process for
    establishing the market spot price for platinum and palladium called
    the “Fixing.” Id. at 373. The Fixing was conducted twice daily—in an
    “AM Fixing” and a “PM Fixing”—with a private conference call that
    would set global benchmark prices for platinum and palladium. To
    conduct the Fixing, BASF Metals, Goldman Sachs, HSBC, and ICBC
    established the London Platinum and Palladium Fixing Company
    Ltd. (“LPPFC”). The LPPFC has its principal place of business in
    London, England, and “is 100% owned and controlled” by the four
    7
    entities that founded it. Id. at 371. Its “only function is to take on and
    continue the promotion, administration and conduct of [the Fixing].”
    Id. (internal quotation marks omitted).
    The Fixing was designed to be conducted as a Walrasian
    auction. 1 One of the four founding entities would serve as the chair of
    the auction, and the chair would announce an opening price
    “ostensibly at or near the current spot price.” App’x 374. Each of the
    other three founding entities would then declare itself to be a net
    buyer or a net seller or to have no interest. The chair would adjust the
    price until there was no (or nearly no) net interest in buying or selling,
    and the resulting price would serve as the benchmark price—or the
    “Fix price.”
    Once the chair announced the benchmark price, the orders of
    the auction participants could not be retracted. But the effects of the
    benchmark extended beyond those orders. Market participants
    uninvolved in the Fixing frequently incorporated the benchmark
    prices in contracts. When buyers and sellers entered “spot”
    contracts—pursuant to which the contracting parties agreed to
    consummate the purchase and sale of physical platinum or
    palladium—the “spot price” was “often tied or keyed to the relevant
    metal’s Fixing on the day of the sale.” Id. at 380. Because the prices of
    NYMEX platinum and palladium closely tracked the spot prices of
    1In a Walrasian auction, each trader “submit[s] his demand, or even his
    demand schedule,” to the auctioneer, who “aggregates traders’ demands
    and supplies to find a market-clearing price.” Maureen O’Hara, Market
    Microstructure Theory 4 (1995). In this way, the final price is the result of “an
    unseen trading game in which buyers and sellers costlessly exchange
    assets.” Id.
    8
    those metals, the result was that “[t]he spot, Fix, and NYMEX
    settlement prices exhibit[ed] an almost perfect correlation.” Id. at 387.
    II
    The Fixing would have been “a competitive process” if it were
    conducted properly. Id. at 352. The plaintiffs allege that it was not so
    conducted.
    The plaintiffs-appellants in this case are Larry Hollin, White
    Oak Fund LP (“White Oak”), and KPFF Investment, Inc. (“KPFF”).
    Hollin and White Oak sold NYMEX platinum or palladium futures
    contracts (collectively, the “Exchange Plaintiffs”). KPFF sold physical
    platinum and palladium. All of the plaintiffs-appellants reside in the
    United States.
    According to the plaintiffs, the defendants had the opportunity
    and the motive to use the Fixing to manipulate the benchmark prices
    of platinum and palladium toward lower prices. The plaintiffs alleged
    collusion among the defendants in several ways. Each Fixing call
    “involved the direct exchange of intended or future price information
    among horizontal competitors.” Id. at 448. The defendants also moved
    the market downward by coordinating large sell orders, which would
    lower the opening price for the Fixing. During the Fixing itself, the
    defendants affected the benchmark price by “submit[ting] aggregate
    ‘auction’ ‘bids’ that understated demand.” Id. at 452. All the while, the
    defendants coordinated their behavior using “chat rooms, instant
    messages, phone calls, proprietary trading venues and platforms, and
    e-mails.” Id. at 449. The motive for such collusion, the plaintiffs
    contend, was that the defendants “are traders of Physical and
    NYMEX Platinum and Palladium and … had large short futures
    positions on NYMEX.” Id. at 474.
    9
    Five complaints based on this alleged conduct—each seeking
    to bring claims individually and on behalf of a class—were filed
    between November 2014 and March 2015. On March 20, 2015, the
    district court consolidated the five cases. Four months and two
    amendments later, the plaintiffs filed a second consolidated class
    action complaint. This second amended complaint named BASF
    Metals, Goldman Sachs, HSBC, ICBC, the LPPFC, BASF Corporation,
    UBS AG, and UBS Securities LLC as defendants. BASF Corporation,
    a “carrier, assayer, and refiner of platinum and palladium,” is a sister
    company of BASF Metals and is registered in Delaware. Id. at 85-86.
    UBS AG and UBS Securities—a wholly owned subsidiary of UBS
    AG—are financial services companies involved in trading physical
    and NYMEX platinum and palladium.
    The second amended complaint brought seven causes of action
    alleging (1) an agreement restraining trade in violation of the
    Sherman Act, 
    15 U.S.C. § 1
    , (2) five violations of the CEA, 
    7 U.S.C. § 1
    et seq., and (3) unjust enrichment. The plaintiffs alleged that the
    “manipulation of the Fixing by the Defendants impacted” the
    plaintiffs’ transactions and caused the plaintiffs “to incur greater
    losses and/or realize lower prices than they would have realized in a
    free and open competitive market.” Id. at 193. The plaintiffs also
    sought to certify a class of persons and entities similarly situated who
    engaged in certain transactions in platinum or palladium during the
    period from January 1, 2008, through November 30, 2014.
    The defendants moved to dismiss the complaint, and the
    district court granted the motion in part and denied it in part. In re
    Platinum & Palladium Antitrust Litig. (Platinum I), No. 14-CV-9391,
    
    2017 WL 1169626
    , at *2 (S.D.N.Y. Mar. 28, 2017). First, after noting that
    10
    the complaint “is silent with respect to whether … Plaintiffs had any
    direct sales to or purchases from Defendants,” the district court
    dismissed the plaintiffs’ claim under the Sherman Act for lack of
    antitrust standing. Id. at *20-25. Second, the district court denied the
    defendants’ motion to dismiss the CEA claims, granting the motion
    only with respect to the plaintiffs’ claims “based on false reports and
    transactions that precede the effective date of” Commodity Futures
    Trading Commission (“CFTC”) Rule 180.1. Id. at *36. Third, because
    the plaintiffs did not allege any direct transactions with the
    defendants, the district court held that “they have not adequately
    pleaded that Defendants were enriched at their expense” and
    dismissed the unjust enrichment claim. Id. at *38. Additionally, the
    district court dismissed all claims against BASF Corporation, UBS
    AG, and UBS Securities for failure to state how those entities were
    involved in the alleged misconduct. See id. at *51 (“UBS is not alleged
    to have been a member of the Fixing during the Class Period, or to
    have participated in the Fixing, either directly or indirectly.”); id. at
    *52   (“[T]he   [complaint]    says    nothing   about   BASF    Corp.’s
    involvement—direct or indirect—in the alleged price manipulation,
    BASF Corp.’s role in executing the scheme, or BASF Corp.’s motive in
    artificially suppressing the Fix Price.”).
    BASF Metals, ICBC, and the LPPFC (collectively, the “Foreign
    Defendants”) also filed a motion to dismiss the complaint for lack of
    personal jurisdiction, which the district court granted. Id. at *2. The
    district court held that the plaintiffs “have not made a prima facie
    showing that the Foreign Defendants have sufficient contacts with the
    United States as a whole.” Id. at *44. Additionally, the district court
    rejected the plaintiffs’ argument that it could hear the suit under a
    theory of conspiracy jurisdiction. Id. at *49. The district court
    11
    concluded its order by granting the plaintiffs leave to amend the
    complaint a third time. Id. at *53.
    On May 15, 2017, the plaintiffs filed a third amended complaint
    that differed from the previous complaint in several respects. The
    complaint no longer named the LPPFC, BASF Corporation, UBS AG,
    and UBS Securities as defendants. It also no longer brought claims for
    unjust enrichment or CEA claims based on Rule 180.1 for conduct that
    preceded the rule’s enactment.
    Most important, the plaintiffs added allegations relating to
    antitrust standing and personal jurisdiction. As to antitrust standing,
    the complaint provided allegations to demonstrate “[t]he close
    relationship between the Fix[ing] and NYMEX futures prices,” “[t]he
    Defendants’ substantial market share in physical platinum and
    palladium as well as NYMEX platinum and palladium futures and
    options,” and “Plaintiffs’ ability to assess damages through
    discovery.” App’x 350-51. As to personal jurisdiction, the complaint
    provided allegations “pertaining to [BASF Metals’s and ICBC’s]
    continuous presence in the U.S. and their suit-related conduct in the
    U.S.” Id. at 350.
    While the third amended complaint was pending, this court
    decided Charles Schwab Corp. v. Bank of America Corp. (Schwab I), 
    883 F.3d 68
     (2d Cir. 2018), and Prime International Trading, Ltd. v. BP P.L.C.,
    
    937 F.3d 94
     (2d Cir. 2019). Those cases addressed, respectively,
    whether a conspiracy theory of jurisdiction establishes personal
    jurisdiction over a co-conspirator and whether the CEA has
    extraterritorial application. See Schwab I, 
    883 F.3d at 86-87
    ; Prime Int’l,
    937 F.3d at 102-04. In response to Prime International, the defendants
    sought reconsideration of the district court’s denial of the motion to
    12
    dismiss with respect to the CEA claims. In re Platinum & Palladium
    Litig. (Platinum II), 
    449 F. Supp. 3d 290
    , 302 (S.D.N.Y. 2020).
    Taking the new allegations and the recent case law into
    account, the district court dismissed in part the third amended
    complaint. Id. at 298. The district court again concluded that the
    plaintiffs lacked antitrust standing, but this time the district court
    separately analyzed the antitrust standing of KPFF, which transacted
    solely in physical platinum and palladium, and the antitrust standing
    of the other plaintiffs, which transacted on the NYMEX. Id. at 303. The
    district court held that KPFF lacked antitrust standing because “the
    [complaint] does not allege that [KPFF] transacted directly with any
    defendant.” Id. at 304. With respect to the plaintiffs that transacted on
    the NYMEX, the district court was persuaded that the “line between
    those who transacted directly with defendants and those who did
    not” had little meaning in the exchange context. Id. at 311. Instead, the
    district court adopted a “market domination” test that other district
    courts in this circuit have applied. Id. at 312. Under that test, plaintiffs
    must “allege that defendants dominated the relevant exchange
    market” to establish antitrust standing. Id. (“Recognizing that
    counterparties to exchange plaintiffs are not reasonably ascertainable,
    judges in this district have adopted a test that depends primarily on
    the extent of defendants’ control of the market for the product traded
    on the exchange.”) (internal quotation marks omitted). Because it
    determined that the NYMEX plaintiffs “have not adequately pleaded
    that Defendants dominated the NYMEX market for platinum and
    palladium derivatives,” the district court held that those plaintiffs
    lacked antitrust standing as well. Id. at 317.
    13
    The district court reached a different conclusion with respect to
    personal jurisdiction. The district court understood Schwab I to allow
    the exercise of personal jurisdiction in this case if “United-States-
    based co-conspirators acted in furtherance of the conspiracy.” Id. at
    323-24 (internal quotation marks omitted). Because the third
    amended complaint “alleges United-States based traders for affiliates
    of BASF Metals and [ICBC] provided non-public client order
    information directly to Fixing participants” in furtherance of the
    conspiracy, the district court held that it had personal jurisdiction
    over BASF Metals and ICBC. Id. at 325-26. The district court denied
    the defendants’ motion to dismiss under Rule 12(b)(2).
    Success on the jurisdictional issue did not mean overall success
    for the plaintiffs, however, because the district court granted the
    defendants’ motion to reconsider its holding on the CEA claims. Id. at
    332. Based on Prime International, the district court concluded that the
    plaintiffs’ CEA claims “are predominantly foreign” and therefore
    “impermissibly extraterritorial.” Id. at 331. The district court
    dismissed the CEA claims without prejudice and granted the
    plaintiffs leave to amend the Sherman Act and CEA claims. Id. at 332-
    33.
    In sum, the district court denied BASF Metals’s and ICBC’s
    motion to dismiss for lack of personal jurisdiction, but it granted the
    defendants’ motion to dismiss for failure to state a claim as well as the
    defendants’ motion for reconsideration. Rather than file another
    amended complaint, the plaintiffs requested that the district court
    enter final judgment, which the district court did on April 15, 2020. Of
    the plaintiffs, only Hollin, White Oak, and KPFF appealed. BASF
    Metals and ICBC cross-appealed the district court’s denial of their
    14
    motion to dismiss for lack of personal jurisdiction.
    DISCUSSION
    “We review de novo the grant of a motion to dismiss, accept as
    true all factual claims in the complaint, and draw all reasonable
    inferences in the plaintiffs’ favor.” In re Aluminum Warehousing
    Antitrust Litig., 
    833 F.3d 151
    , 157 (2d Cir. 2016).
    According to the plaintiffs, the district court erred (1) in
    holding that the plaintiffs lack antitrust standing, (2) in holding that
    the CEA claims were impermissibly extraterritorial, (3) in dismissing
    the LPPFC for lack of personal jurisdiction, and (4) in dismissing the
    second amended complaint as to BASF Corporation for failure to state
    a claim. BASF Metals and ICBC—the only cross-appellants in this
    case—argue that the district court erred in holding that it had
    personal jurisdiction to hear claims against them. We address these
    arguments in turn.
    I
    We begin with the plaintiffs’ Sherman Act claims. Section 1 of
    the Sherman Act provides that “[e]very contract, combination in the
    form of trust or otherwise, or conspiracy, in restraint of trade or
    commerce among the several States … is declared to be illegal.”
    
    15 U.S.C. § 1
    . The Clayton Act provides a private cause of action for
    injuries “by reason of anything forbidden in the antitrust laws,” 
    id.
    § 15(a), as well as a private cause of action to seek “injunctive relief …
    against threatened loss or damage by a violation of the antitrust
    laws,” id. § 26. The plaintiffs claim that the defendants violated the
    Sherman Act when they “conspir[ed] to manipulate platinum and
    palladium market prices and the benchmark price” and seek treble
    15
    damages and injunctive relief because the conspiracy affected “the
    price of Physical and NYMEX Platinum and Palladium.” App’x 491-
    92.
    The district court dismissed these claims for lack of antitrust
    standing. The antitrust standing requirement “originates in the
    Supreme Court’s recognition that … ‘Congress did not intend the
    antitrust laws to provide a remedy in damages for all injuries that
    might conceivably be traced to an antitrust violation.’” Daniel v. Am.
    Bd. of Emergency Med., 
    428 F.3d 408
    , 436-37 (2d Cir. 2005) (quoting
    Associated Gen. Contractors of Cal., Inc. v. Cal. State Council of Carpenters
    (AGC), 
    459 U.S. 519
    , 534 (1983)). “To establish antitrust standing, a
    plaintiff must show (1) antitrust injury, which is injury of the type the
    antitrust laws were intended to prevent and that flows from that
    which makes defendants’ acts unlawful, and (2) that he is a proper
    plaintiff in light of four efficient enforcer factors.” Schwab Short-Term
    Bond Mkt. Fund v. Lloyds Banking Grp. PLC (Schwab II), 
    22 F.4th 103
    ,
    115 (2d Cir. 2021) (internal quotation marks omitted). Whether a
    plaintiff is an efficient enforcer depends on:
    (1) the directness or indirectness of the asserted injury;
    (2) the existence of more direct victims or the existence of
    an identifiable class of persons whose self-interest would
    normally motivate them to vindicate the public interest
    in antitrust enforcement; (3) the extent to which the claim
    is highly speculative; and (4) the importance of avoiding
    either the risk of duplicate recoveries on the one hand, or
    the danger of complex apportionment of damages on the
    other.
    In re Am. Express Anti-Steering Rules Antitrust Litig., 
    19 F.4th 127
    , 138
    (2d Cir. 2021) (internal quotation marks omitted). “[T]he weight to be
    16
    given the various factors will necessarily vary with the circumstances
    of particular cases.” Daniel, 428 F.3d at 443.
    The district court separately analyzed the antitrust standing of
    KPFF, which traded in the physical market for platinum and
    palladium, and the antitrust standing of the Exchange Plaintiffs, who
    traded only on the exchange market for those metals. It determined
    that none of the plaintiffs were efficient enforcers and that no plaintiff
    had antitrust standing. We agree with the district court as to KPFF but
    disagree as to the other plaintiffs. We hold that the Exchange Plaintiffs
    have antitrust standing.
    A
    We first consider whether KPFF has antitrust standing. KPFF
    alleges that it “sold physical platinum and palladium … at artificial
    prices proximately caused by Defendants’ unlawful manipulation.”
    App’x 362. The district court determined that the complaint “does not
    allege that [KPFF] transacted directly with any defendant,” Platinum
    II, 449 F. Supp. 3d at 304, and KPFF on appeal concedes that it “did
    not transact with a Defendant,” Appellants’ Br. 45. Based on the
    efficient-enforcer factors, we agree with the district court that KPFF
    lacks antitrust standing in this case.
    1
    The first efficient-enforcer factor—“whether the violation was
    a direct or remote cause of the injury”—turns on “familiar principles
    of proximate causation.” Am. Express, 19 F.4th at 139. “In the context
    of antitrust standing, proximate cause generally follows the first-step
    rule.” Id. That rule “requires some direct relation between the injury
    asserted and the injurious conduct alleged.” Id. at 140 (internal
    17
    quotation marks omitted); see also Gatt Commc’ns, Inc. v. PMC Assocs.,
    L.L.C., 
    711 F.3d 68
    , 78 (2d Cir. 2013) (“Directness in the antitrust
    context means close in the chain of causation.”) (quoting IBM Corp. v.
    Platform Sols., Inc., 
    658 F. Supp. 2d 603
    , 611 (S.D.N.Y. 2009)).
    “Our court has repeatedly followed the first-step rule in the
    antitrust context.” Am. Express, 19 F.4th at 140. In American Express,
    we held that merchants who complained of anticompetitive conduct
    by American Express Company (“Amex”) but did not accept
    American Express cards lacked antitrust standing to sue. Id. at 134-35.
    We reasoned that, “[a]t the first step, Amex raised the price for Amex-
    accepting merchants,” and only at a later step did Amex’s competitors
    follow suit and raise the price for the plaintiff merchants. Id. at 140-
    41. Accordingly, the plaintiff merchants’ injuries “were not
    proximately caused by Amex; the alleged antitrust violation was
    instead a ‘remote’ cause of the injuries.” Id. at 141.
    In Schwab II, we considered the London Interbank Offered Rate
    (“LIBOR”), a “benchmark interest rate” that “serves as an index for a
    variety of financial instruments, including bonds, interest rate swaps,
    commercial paper, and exchange-traded derivatives.” Schwab II,
    22 F.4th at 109-10. Bondholders who “held LIBOR-based bonds issued
    by third parties” alleged that the defendant banks had manipulated
    the LIBOR in violation of the antitrust laws. Id. at 111. We held that
    those bondholders were not efficient enforcers because “the decision
    of a third party to incorporate LIBOR as a term in a financial
    instrument could be made without any connection to the actions” of
    the defendant banks. Id. at 116. Additionally, that decision “in no way
    enriched the [defendant banks], who had no financial stake in the
    [third-party] transactions whatsoever.” Id. Accordingly, “[t]he first-
    18
    step rule and traditional proximate cause considerations require
    drawing a line between those whose injuries resulted from their direct
    transactions with the [defendant banks] and those whose injuries
    stemmed from their deals with third parties.” Id.
    We hold that KPFF has not alleged a direct injury in this case.
    As in Schwab II, the decision to incorporate or reference the
    benchmark price in the transactions into which KPFF entered—and
    by which KPFF was allegedly harmed—was an independent decision.
    The only transactions that were required to adopt the benchmark
    prices were those into which the defendants entered as part of the
    Fixing, and KPFF has concededly not transacted with the defendants.
    We said in Schwab II that the “disconnect” between the
    plaintiffs’ injury and the defendants’ alleged benefit “further
    demonstrates the attenuated nature of the causal chain.” Id. In other
    words, the allegedly harmful transactions in that case “in no way
    enriched” the defendants. Id. In this case, KPFF alleges that the
    conspiracy enabled the defendants, as “large participants in the
    market for physical platinum and palladium,” to “buy platinum and
    palladium cheaper than they would have been able to” otherwise,
    App’x 466, just as the defendant banks in Schwab II “may have
    increased their profits by selling LIBOR-indexed instruments,”
    22 F.4th at 116. But the defendants “derived no benefit from [KPFF’s]
    transactions with third parties,” which “were entirely separate from
    the purpose of the alleged conspiracy and took place merely because
    of [the benchmark’s] unlimited public availability as a reference point
    for innumerable transactions.” Id. at 117.
    KPFF argues that this case differs from Schwab II because, in
    this case, KPFF alleges a “lockstep” relationship between the
    19
    benchmark prices and the spot prices—and provided “the kind of
    statistical allegations” to prove that relationship—that was absent
    from the Schwab II plaintiffs’ case. Appellants’ Supp. Br. 14. In Sanner
    v. Board of Trade, the Seventh Circuit characterized the futures market
    and the cash market for the same commodity as exhibiting a
    “lockstep” relationship. 
    62 F.3d 918
    , 929 (7th Cir. 1995). 2 To prove that
    such a relationship is present here, KPFF provides charts to show that
    “[t]he spot, Fix, and NYMEX settlement prices exhibit an almost
    perfect correlation.” App’x 387-88.
    We disagree that Schwab II can be framed as a mere failure of
    proof. In Schwab II, the plaintiffs held “LIBOR-based bonds,” which
    “incorporate[d] LIBOR as a term.” 22 F.4th at 116. If the court were
    merely seeking evidence of a close relationship between LIBOR and
    the plaintiffs’ bonds, the incorporation of the benchmark into the
    bonds would have sufficed. Instead, we found it significant that the
    plaintiffs independently decided to incorporate the LIBOR in
    contracts with third parties; those decisions “snap the chain of
    causation linking [p]laintiffs’ injury to the [b]anks’ misconduct.” Id.
    2 Sanner involved the Chicago Board of Trade’s July 11, 1989, resolution that
    “required all holders of gross long positions in soybean futures contracts to
    liquidate their positions by at least 20 percent daily until July 20, 1989.”
    
    62 F.3d at 920-21
    . The plaintiffs were soybean farmers who alleged that the
    resolution “was prompted by a conspiracy to cause a precipitous drop in
    soybean cash crop prices” and brought antitrust claims against the Board.
    
    Id. at 921
    . Despite the farmers being in the cash market for soybeans, as
    opposed to the futures market, the court held that “[s]ince one market tends
    to move in lockstep with the other, participants in the cash market can be
    injured by anticompetitive acts committed in the futures market.” 
    Id. at 929
    .
    The court held that the farmers had alleged a direct injury for purposes of
    antitrust standing.
    20
    Accordingly, KPFF’s causal link between the benchmark prices
    and its own transactions—even if more fully documented than the
    one in Schwab II—does not transform its indirect injury into a direct
    one. As in Schwab II, transactions in the commodity (here, platinum
    and palladium) were “often tied or keyed to” the benchmark prices,
    but KPFF’s injury was separated from the defendants’ conduct by the
    decision to incorporate the benchmark. App’x 380.
    We hold that KPFF’s injury is indirect for purposes of antitrust
    standing.
    2
    The remaining efficient-enforcer factors do not establish
    antitrust standing for KPFF. As noted above, “the weight to be given
    the various factors will necessarily vary with the circumstances of
    particular cases.” Daniel, 428 F.3d at 443. “Though Associated General
    Contractors outlined a comprehensive approach to the question of
    antitrust standing, it gives little guidance as to how to weigh the
    various factors, and whether the absence of a particular factor would
    be fatal to standing in every instance.” Sullivan v. Tagliabue, 
    25 F.3d 43
    , 46 (1st Cir. 1994). We look to our precedents to decide how the
    efficient-enforcer factors must be balanced. In this case, the first and
    second factors are decisive.
    We held in Schwab II that the second factor—“the existence of
    more direct victims of the alleged conspiracy”—“clearly weighs
    against antitrust standing since there is no shortage of other parties in
    this very case who purchased LIBOR-indexed financial instruments
    directly” from the defendants. 22 F.4th at 118. In this case, the fact that
    there are platinum and palladium sellers who have directly
    transacted with the defendants “diminishes the justification for
    21
    allowing a more remote party to perform the office of a private
    attorney general.” Am. Express, 19 F.4th at 141 (alteration omitted)
    (quoting AGC, 
    459 U.S. at 542
    ). The second factor “weighs against
    antitrust standing” for that reason. Schwab II, 22 F.4th at 118.
    The fourth efficient-enforcer factor—“the importance of
    avoiding either the risk of duplicate recoveries on the one hand, or
    the danger of complex apportionment of damages on the other”—
    favors the plaintiffs, as it did in Schwab II. 22 F.4th at 119. The fourth
    factor guards against “pass-on theories that would require a court to
    divide damages from the same violation among multiple plaintiffs.”
    Am. Express, 19 F.4th at 143; see also Schwab II, 22 F.4th at 119
    (describing pass-on theories as “the usual focus” of the fourth factor).
    We held in Schwab II that the fourth factor favored the plaintiffs
    because “the third parties who sold the bonds—and benefited from the
    suppressed rate—would clearly not be in a position to enforce the
    antitrust laws.” 22 F.4th at 119. The same logic applies in this case.
    Whoever purchased palladium or platinum from KPFF benefited
    from the lowered price, and there is no concern that those purchasers
    would sue the defendants or cause any complex problems of
    apportionment. Thus, we “view this fourth factor as favoring” KPFF.
    Id.
    This case differs from Schwab II with respect to the third
    efficient-enforcer factor—“whether the alleged damages are highly
    speculative.” Id. (internal quotation marks omitted). The third factor
    evaluates whether the plaintiff can produce “a just and reasonable
    estimate of damages.” Gelboim v. Bank of Am. Corp., 
    823 F.3d 759
    , 779
    (2d Cir. 2016) (internal quotation marks omitted) (quoting U.S.
    Football League v. Nat’l Football League, 
    842 F.2d 1335
    , 1378 (2d Cir.
    22
    1988)). “[H]ighly speculative damages is a sign that a given plaintiff
    is an inefficient engine of enforcement.” 
    Id.
     In Schwab II, we held that
    this factor cut against antitrust standing because calculating damages
    “would require the court to speculate about how the third-party
    sellers would have factored a non-suppressed LIBOR into the
    transaction.” 22 F.4th at 119. To estimate the damages, the plaintiffs
    “would essentially have to create an alternative universe” beyond
    modeling “basic lost sales and lost profits.” Id. (internal quotation
    marks and alterations omitted). At the same time, we gave this factor
    “only limited weight” because the damages calculation would be
    “more straightforward” for the plaintiffs who purchased bonds prior
    to the LIBOR being suppressed and because “[t]he Supreme Court has
    warned that antitrust standing should not provide a ‘get-out-of-court-
    free card’ to be played ‘any time that a damages calculation might be
    complicated.’” Id. (quoting Apple Inc. v. Pepper, 
    139 S. Ct. 1514
    , 1524
    (2019)).
    The third factor favors KPFF in this case. Unlike in Schwab II,
    the benchmark prices for platinum and palladium are derived from
    the same kind of transactions that incorporated the benchmark prices.
    Damages were speculative in Schwab II because the LIBOR aimed to
    describe the rate at which certain banks could borrow money but it
    was incorporated into the terms of unrelated bonds. That disjunction
    meant that the plaintiffs would have needed to account for such
    possibilities as whether “the price of the bond itself may have been
    correspondingly lowered to account for a suppressed LIBOR.” 
    Id.
     In
    this case, the benchmark price describes the price at which the
    defendants buy metal, and KPFF alleges that the benchmark price
    was used in its transactions to sell the same type of metal. KPFF has
    provided data to show that the prices at which it sold the metal and
    23
    the benchmark prices were all but identical. Thus, even though the
    “damages calculation might be complicated,” Apple, 
    139 S. Ct. at 1524
    ,
    the damages are not so speculative as to weigh against antitrust
    standing in this case.
    Even so, we ultimately conclude that KPFF cannot pursue its
    antitrust claims. “The four efficient-enforcer factors need not be given
    equal weight,” and the fact that KPFF’s injury “may have been
    foreseeable, predictable, and even calculable” is not by itself sufficient
    to confer antitrust standing. Am. Express, 19 F.4th at 142. In American
    Express, we determined that only the first two efficient-enforcer
    factors weighed against standing. Id. at 143. We nevertheless held that
    because “[t]he key principle underlying [the efficient enforcer test] is
    proximate cause” and the plaintiffs “fail[ed] to show the required
    direct connection between the harm and the alleged antitrust
    violation,” the plaintiffs lacked antitrust standing. Id. In the same
    way, the absence of a direct connection between the harm and the
    violation and the existence of more direct victims are decisive here.
    We affirm the district court’s dismissal of KPFF’s antitrust claims.
    B
    We next consider whether the Exchange Plaintiffs have alleged
    antitrust standing. The Exchange Plaintiffs did not participate in the
    physical platinum and palladium market; instead, the Exchange
    Plaintiffs allegedly sold “NYMEX platinum and palladium futures
    contracts at artificial prices proximately caused by Defendants’
    unlawful manipulation.” App’x 361. The district court held that these
    plaintiffs also lacked antitrust standing.
    We disagree. The antitrust standing question depends on “the
    relationship between the defendant’s alleged unlawful conduct and
    24
    the resulting harm to the plaintiff.” Am. Express, 19 F.4th at 143
    (quoting Am. Ad Mgmt., Inc. v. Gen. Tel. Co. of Cal., 
    190 F.3d 1051
    , 1058
    (9th Cir. 1999)). “We employ the efficient-enforcer test to evaluate the
    relevant relationship.” 
    Id.
     After considering the four factors, we hold
    that the Exchange Plaintiffs are efficient enforcers of the antitrust
    laws.
    1
    Unlike KPFF, the Exchange Plaintiffs suffered a direct injury.
    The complaint alleges that the defendants were “large participants in
    NYMEX futures and options” and “profited from their manipulation”
    of the futures market. App’x 466. The Exchange Plaintiffs argue that
    the defendants “exploited their foreknowledge of downward swings
    in the [benchmark price] to make advantageous trades in … [the]
    NYMEX markets.” Appellants’ Br. 10. Apart from the Fixing itself, the
    Exchange Plaintiffs allege that the defendants engaged in collusive
    trading to move the NYMEX market downward. According to the
    Exchange Plaintiffs, the defendants “profited from their manipulation
    … at the expense of” the Exchange Plaintiffs. App’x 466. In other
    words, the defendants manipulated the futures market to profit from
    futures contracts transactions, while the Exchange Plaintiffs
    simultaneously lost money through futures contracts transactions in
    the same market. The Exchange Plaintiffs were harmed at the first
    step.
    The defendants argue that the plaintiffs’ injury cannot be direct
    because,     as   the   complaint       notes,   “NYMEX—through       its
    clearinghouse, CME Clearing—is the counterparty to all transactions
    on the exchange.” 
    Id. at 381
    . Thus, although the Exchange Plaintiffs
    and the defendants all traded in the same market, each traded directly
    25
    only with CME Clearing. According to the defendants, “[t]he
    reasoning in Schwab II applies with full force to the Exchange
    Plaintiffs” because the Exchange Plaintiffs “did not transact with any
    defendant.” Appellees’ Supp. Br. 7 n.2.
    We disagree. “Futures trading is a zero-sum game” because
    “every contract has a long and a short” and “every gain can be
    matched with a corresponding loss.” Leist v. Simplot, 
    638 F.2d 283
    , 286-
    87 (2d Cir. 1980). Although CME Clearing is, formally, the
    counterparty to every transaction, it serves only as a conduit: “CME
    Clearing matches buyers and sellers.” App’x 382; see also Amaranth
    Nat. Gas, 
    730 F.3d at 174
     (“All trades on NYMEX must go through the
    exchange’s clearinghouse.”) (emphasis added). We would have no
    difficulty identifying a direct injury if the defendants had selected
    another NYMEX participant with which to execute a futures contract,
    even if a clearinghouse facilitated the transaction. To argue, as the
    defendants do, that interposing a clearinghouse immunizes
    misconduct on an exchange market from antitrust liability is to exalt
    form over substance. 3
    3We note that this case differs from Laydon v. Coöperatieve Rabobank U.A., in
    which we held that a plaintiff who traded Euroyen TIBOR futures on an
    exchange lacked antitrust standing. 
    55 F.4th 86
    , 98-99 (2d Cir. 2022). In that
    case, a plaintiff alleged that defendant banks made fraudulent submissions
    to the British Bankers’ Association, a body that set the Yen-LIBOR
    benchmark rate, which in turn affected a second benchmark rate that was
    set by the Japanese Bankers Association, causing losses to traders in futures
    that referenced the second benchmark rate. We said that the plaintiff failed
    to allege proximate causation because of the “series of causal steps that
    separate [the d]efendants’ conduct and [the plaintiff’s] purported injury.”
    Id. at 98. In this case, the defendants transacted on the same exchange as the
    Exchange Plaintiffs and we do not have the same attenuated causal chain.
    26
    The district court viewed the effect of the clearinghouse
    differently than the defendants. Because of the clearinghouse, the
    district court concluded that “the Exchange Plaintiffs’ counterparties
    are not reasonably ascertainable” and instead used market
    dominance as a proxy for directness of injury. Platinum II, 449
    F. Supp. 3d at 311. According to the district court, “in a market in
    which defendants dominate, it is far more likely that a plaintiff who
    bought on an exchange will have transacted directly with a
    defendant.” Id. at 312. Additionally, “concern[s] about damages
    disproportionate to wrongdoing” would “appl[y] much less
    forcefully” when the defendants dominate the market; “where
    defendants had over 90% market share, they would also be
    responsible for over 90% of the damages.” Id. In adopting this test, the
    district court followed other district courts in this circuit. See, e.g., In
    re London Silver Fixing, Ltd., Antitrust Litig., 
    332 F. Supp. 3d 885
    , 909
    (S.D.N.Y. 2018); Sonterra Cap. Master Fund Ltd. v. Credit Suisse Grp. AG,
    
    277 F. Supp. 3d 521
    , 561-62 (S.D.N.Y. 2017).
    Although the defendants’ market share may inform the amount
    of damages the Exchange Plaintiffs can seek, we disagree that it can
    render the Exchange Plaintiffs’ injury indirect. “The first-step rule
    requires some direct relation between the injury asserted and the
    injurious conduct alleged.” Am. Express, 19 F.4th at 139-40. Market
    dominance does not determine whether such a relation exists. The
    defendants     allegedly    sought     to   profit   from    concurrently
    manipulating the Fixing and entering the futures market. That profit
    came at the expense of the other futures market participants. The
    members of that group are—as the defendants contend—
    interchangeable, and that group includes the Exchange Plaintiffs.
    That the defendants’ profits cannot be traced to a subgroup of those
    27
    market participants is not a reason to conclude that none of those
    participants suffered a direct injury. To hold otherwise would be to
    hold that anticompetitive behavior on an exchange can directly injure
    no one.
    We conclude that the Exchange Plaintiffs have adequately
    alleged a direct injury.
    2
    We hold that the remaining efficient-enforcer factors favor
    antitrust standing for the Exchange Plaintiffs as well.
    First, there are no more direct victims than the Exchange
    Plaintiffs. Because all participants in the NYMEX transact through the
    clearinghouse, there is no injured party closer to the defendants’
    alleged anticompetitive activity than the Exchange Plaintiffs. If the
    Exchange Plaintiffs do not have antitrust standing, the defendants’
    alleged conspiracy to manipulate the exchange market would go
    “undetected or unremedied.” Am. Express, 19 F.4th at 141 (quoting
    AGC, 
    459 U.S. at 542
    ).
    The defendants contend that the existence of sellers who sold
    physical platinum and palladium to the defendants means that those
    sellers are more direct victims. According to the defendants, “[t]he
    question is whether there are ‘more direct victims of the alleged
    conspiracy,’ not among a particular subset of those allegedly affected.”
    Appellees’ Supp. Reply Br. 4 (quoting Schwab II, 22 F.4th at 118).
    Because the conspiracy sought to affect the physical platinum and
    palladium market in addition to the futures market, the defendants
    argue, the second factor must take the victims in that market into
    account as well.
    28
    The defendants’ argument rests on false premises. The
    assertion that the direct victims in the physical market are better
    situated to sue is based on the defendants’ argument that the
    Exchange Plaintiffs are indirect victims. But because we hold that the
    Exchange Plaintiffs are direct victims, even if we were to include the
    victims in the physical market in our analysis, there is no reason to
    think that those victims are more direct than the Exchange Plaintiffs.
    Nor does it make sense for victims in one market to disqualify victims
    in a different market from bringing suit. 4
    In In re Aluminum Warehousing Antitrust Litigation, we held that
    purchasers in the physical aluminum market who had alleged a
    conspiracy by traders in the aluminum futures market had not
    suffered an antitrust injury. 
    833 F.3d at 161-62
    . We reached that
    conclusion by treating the physical market as separate from the
    futures market; because typically “only those that are participants in
    the defendants’ market can be said to have suffered antitrust injury,”
    we dismissed the plaintiffs’ claims without reaching the efficient-
    enforcer analysis. 
    Id. at 158
    . In this case, the physical market victims
    cannot allege the same type of injury that the Exchange Plaintiffs
    suffered. It is hard to see how the “self-interest” of those victims can
    render the Exchange Plaintiffs’ suit—alleging injuries in a different
    and larger market—superfluous. Am. Express, 19 F.4th at 141.
    Second, we do not think that calculating damages would be so
    “highly speculative” that the Exchange Plaintiffs should be denied
    antitrust standing. AGC, 
    459 U.S. at 542
    . “A damages calculation for a
    4In Laydon, we concluded that the plaintiff was not a direct victim of the
    alleged conspiracy and for that reason looked for participants in other
    markets who might be more direct victims. Laydon, 55 F.4th at 99.
    29
    market manipulation scheme, though it may require expert
    testimony, is hardly beyond the ken of the federal courts.” Sanner, 
    62 F.3d at 930
    . “[S]ome degree of uncertainty stems from the nature of
    antitrust law,” Gelboim, 
    823 F.3d at 779
    , but we generally require “that
    the wrongdoer shall bear the risk of the uncertainty which his own
    wrong has created,” 
    id.
     (quoting In re DDAVP Direct Purchaser
    Antitrust Litig., 
    585 F.3d 677
    , 689 (2d Cir. 2009)).
    Third, there is no risk of “duplicate recoveries” or “complex
    apportionment of damages.” AGC, 
    459 U.S. at 544
    . There was no
    intermediary between the Exchange Plaintiffs and the defendants
    who could sue for the defendants’ anticompetitive conduct in the
    exchange markets. Accordingly, recognizing antitrust standing in this
    case would not “require a court to divide damages from the same
    violation among multiple plaintiffs.” Am. Express, 19 F.4th at 143.
    We hold that the Exchange Plaintiffs have antitrust standing to
    proceed on their claims under the Clayton Act. 5
    5KPFF and the Exchange Plaintiffs also seek injunctive relief under § 16 of
    the Clayton Act. Because standing to sue for injunctive relief “raises no
    threat of multiple lawsuits or duplicative recoveries,” the third and fourth
    efficient enforcer factors “are not relevant” to standing to pursue such relief.
    Cargill, Inc. v. Monfort of Colo., Inc., 
    479 U.S. 104
    , 111 n.6 (1986). Based on the
    remaining factors, our disposition of KPFF’s and the Exchange Plaintiffs’
    respective claims for injunctive relief is the same as each party’s claim for
    damages. The Exchange Plaintiffs have antitrust standing, and KPFF does
    not. However, we note that it is unclear what injunctive relief would be
    available to the plaintiffs, given that the alleged misconduct occurred in the
    past. The district court may consider on remand whether to dismiss the
    Exchange Plaintiffs’ request for injunctive relief for failure to state a claim.

    II
    We now consider the district court’s dismissal of the plaintiffs’
    CEA claims. The third amended complaint alleges that the defendants
    manipulated the prices of platinum and palladium in violation of the
    CEA, including CFTC Rule 180.2. In connection with that claim, the
    plaintiffs also allege that the defendants are liable under principal-
    agent and aiding-and-abetting theories for violations of the CEA. The
    district court dismissed the plaintiffs’ CEA claims as impermissibly
    extraterritorial. Platinum II, 449 F. Supp. 3d at 327-28. We disagree,
    and we vacate the district court’s dismissal of those claims.
    “The CEA is a remedial statute that serves the crucial purpose
    of protecting the innocent individual investor—who may know little
    about the intricacies and complexities of the commodities market—
    from being misled or deceived.” Loginovskaya v. Batratchenko, 
    764 F.3d 266
    , 270 (2d Cir. 2014) (internal quotation marks omitted). Sections 6
    and 9 of the CEA proscribe fraud in commodities markets. 
    7 U.S.C. § 9
    (1) (“It shall be unlawful for any person … to use or employ … in
    connection with any swap, or a contract of sale of any commodity in
    interstate commerce … any manipulative or deceptive device or
    contrivance.”); 
    id.
     § 13(a)(2) (“It shall be a felony … for … [a]ny person
    to manipulate or attempt to manipulate the price of any commodity
    in interstate commerce.”). 6 Private parties have a cause of action to
    sue for violations of the CEA under section 22 of the Act, which
    provides that “[a]ny person … who violates this chapter or who
    6 See also 
    17 C.F.R. § 180.2
     (“It shall be unlawful for any person, directly or
    indirectly, to manipulate or attempt to manipulate the price of any swap, or
    of any commodity in interstate commerce, or for future delivery on or
    subject to the rules of any registered entity.”).
    31
    willfully aids, abets, counsels, induces, or procures the commission of
    a violation of this chapter shall be liable for actual damages.” 
    7 U.S.C. § 25
    (a)(1).
    In Prime International, this court held that sections 6, 9, and 22
    do not apply extraterritorially. 937 F.3d at 102-03. Accordingly,
    stating a proper claim under section 22 has two requirements. First,
    because “the focus of congressional concern in Section 22 is clearly
    transactional, ... the suit must be based on transactions occurring in
    the territory of the United States.” Id. at 104 (internal quotation marks
    omitted). In other words, “[t]he ‘domestic transaction test’ essentially
    ‘decides the territorial reach of Section 22.’” Id. (alteration omitted)
    (quoting Loginovskaya, 
    764 F.3d at 272
    ). Second, because section 22
    “creates no freestanding, substantive legal obligations,” the plaintiff
    must allege “domestic—not extraterritorial—conduct by Defendants
    that is violative of a substantive provision of the CEA, such as
    [
    7 U.S.C. § 9
    (1)] or [§ 13(a)(2)].” Id. at 105. 7
    7 This two-part test comes from Parkcentral Global Hub Ltd. v. Porsche
    Automobile Holdings SE, in which this court held that “a domestic
    transaction is necessary but not necessarily sufficient to make [Securities
    Exchange Act § 10(b)] applicable.” 
    763 F.3d 198
    , 216 (2d Cir. 2014); see Prime
    Int’l, 937 F.3d at 105 (holding that “Parkcentral’s rule carries over to the
    CEA”). Some courts have criticized the conduct requirement as
    “inconsistent with Morrison.” SEC v. Morrone, 
    997 F.3d 52
    , 60 (1st Cir. 2021);
    Stoyas v. Toshiba Corp., 
    896 F.3d 933
    , 950 (9th Cir. 2018). In Morrison v.
    National Australia Bank Ltd., the Supreme Court held that § 10(b) does not
    apply extraterritorially because the statute covers “only transactions in
    securities listed on domestic exchanges, and domestic transactions in other
    securities.” 
    561 U.S. 247
    , 265-67 (2010). The Supreme Court described its
    “transactional test” as a “clear test” that asks “whether the purchase or sale
    is made in the United States, or involves a security listed on a domestic
    32
    Under that analysis, the plaintiffs in this case have alleged a
    domestic application of section 22. We have explained, in the context
    of the Securities Exchange Act, that “there are two ways to allege a
    ‘domestic transaction’”: a plaintiff may allege either “that title … was
    transferred within the United States” or “that the purchaser incurred
    irrevocable liability within the United States to take and pay for a
    security, or that the seller incurred irrevocable liability within the
    United States to deliver a security.” Loginovskaya, 
    764 F.3d at 273-74
    (quoting Absolute Activist Value Master Fund Ltd. v. Ficeto, 
    677 F.3d 60
    ,
    68 (2d Cir. 2012)). The same test applies to CEA claims. Id. at 274.
    Here, the plaintiffs have alleged domestic transactions in both ways.
    First, the Exchange Plaintiffs allege that they sold NYMEX platinum
    and palladium futures contracts. Such sales on a domestic futures
    exchange are domestic transactions. See Morrison, 
    561 U.S. at 269-70
    (noting that the “transactional test” asks whether the purchase or sale
    “is made in the United States, or involves a security listed on a
    domestic exchange”); see also Loginovskaya, 
    764 F.3d at 273-74
    (applying this test in the context of the CEA). Second, KPFF, with a
    principal place of business in California, alleges selling physical
    platinum and palladium, thereby incurring liability to deliver those
    commodities. The plaintiffs have adequately alleged that domestic
    transactions took place.
    exchange.” 
    Id. at 269-70
    . Parkcentral held that, despite the presence of a
    domestic transaction, § 10(b) did not apply because “the claims in this case
    are so predominantly foreign as to be impermissibly extraterritorial.” 763
    F.3d at 216. The court recognized that it was not straightforwardly applying
    Morrison and cautioned that the conduct requirement could not be
    “perfunctorily applied to other cases based on the perceived similarity of a
    few facts.” Id. at 217.
    33
    The plaintiffs also allege domestic conduct by the defendants
    that violated the CEA. To succeed at this step, the conduct must not
    “be so predominantly foreign as to render the claims impermissibly
    extraterritorial.” Prime Int’l, 937 F.3d at 107 (internal quotation marks
    omitted). On this basis, in Prime International we dismissed the CEA
    claims brought by plaintiffs who traded in Brent crude futures on the
    NYMEX and who alleged manipulation of the benchmark for Brent
    crude. We dismissed those claims because the benchmark—which
    “reflect[ed], in part, the value of Brent crude physically traded in
    Northern Europe”—was “foreign.” Id. at 106. Moreover, “[t]he
    alleged misconduct … was also entirely foreign”; there was no
    allegation that “any manipulative oil trading occurred in the United
    States.” Id. Instead, the plaintiffs alleged only that the defendants—“a
    diverse group of entities involved in various aspects of the production
    of Brent crude”—“execut[ed] fraudulent bids, offers, and transactions
    in the underlying physical Brent crude market.” Id. at 98, 100. Because
    “[n]early every link in Plaintiffs’ chain of wrongdoing is entirely
    foreign,” we held that the facts in Prime International were
    predominantly foreign. Id. at 107.
    This case is different. In Prime International we considered both
    the benchmark and the misconduct by which the benchmark was
    manipulated to be “entirely foreign.” Id. at 106. In this case, however,
    the benchmark prices are based on the trading activity of BASF,
    Goldman Sachs, HSBC, and ICBC, each of which conducts precious
    metals trading in the United States. Furthermore, the alleged
    misconduct of manipulating the benchmark prices involved both
    foreign and domestic activity. According to the complaint, the
    defendants “colluded to manipulate the price at which the chair
    opened the Fixing on a given day by placing ‘spoof orders,’ engaging
    34
    in ‘wash sales,’ as well as collusively sharing and acting on non-public
    information regarding client orders (including stop-loss orders)
    shortly before and during the AM and PM Fixing.” App’x 485. “[B]y
    moving Physical and NYMEX Platinum and Palladium prices in
    advance of and even during the Fixing,” the plaintiffs allege, the
    defendants “alter[ed] the starting price” for the Fixing and “g[ave]
    cover to an auction-rate that would otherwise have stood out.” Id. at
    355. The alleged “constant communication” between the defendants’
    domestically based “precious metals traders” and “the participant[s]
    in the Fixing” shows that much of the alleged manipulation was
    domestic. Id. at 365, 368, 376.
    The district court erred in discounting the defendants’ domestic
    activity in furtherance of manipulating the Fixing. The district court
    discounted the plaintiffs’ claim that the defendants traded in the
    physical and NYMEX markets to influence the Fixing because it
    “reject[ed] it as implausible.” Platinum II, 449 F. Supp. 3d at 332.
    According to the district court, “[t]he suggestion that Defendants …
    traded to further depress the price of platinum and palladium when
    they had—according to Plaintiffs’ allegations—a tailor-made
    opportunity to manipulate that price via the Fixing does not make
    sense and is inconsistent with the allegations in the [third amended
    complaint].” Id. But the plaintiffs did not allege that the defendants
    traded to depress the market in a scheme independent of the Fixing;
    the plaintiffs’ theory is that “[t]hese schemes were undertaken for the
    purpose of manipulating the benchmark price.” App’x 485 (emphasis
    added). The defendants’ collusive trading allegedly affected the
    operation of the Fixing by “altering the starting price” and “inducing
    clients to change their directions to the Defendants.” Id. at 355. The
    35
    collusive trading also served the purpose of “giving cover” to the
    defendants’ manipulation of the Fixing. Id.
    Because the district court dismissed the plaintiffs’ claims as
    impermissibly extraterritorial, it did not consider the defendants’
    additional arguments that the plaintiffs failed to plead the required
    elements of a CEA claim. We hold only that the plaintiffs have alleged
    sufficient domestic activity to invoke the CEA’s private remedy.
    Accordingly, we vacate the district court’s dismissal of the plaintiffs’
    CEA claims.
    III
    We turn to the issue of personal jurisdiction. In Platinum I, the
    district court held that it lacked personal jurisdiction over the Foreign
    Defendants: BASF Metals, ICBC, and the LPPFC. Platinum I, 
    2017 WL 1169626
    , at *44. In Platinum II, it held that BASF Metals and ICBC were
    subject to conspiracy jurisdiction in light of Schwab I. 449 F. Supp. 3d
    at 323. Because the plaintiffs did not replead their claims against the
    LPPFC in the third amended complaint, the district court did not
    revisit its earlier dismissal of the LPPFC in Platinum II. Id. at 300 n.4.
    BASF Metals and ICBC argue that the district court erred in
    Platinum II when it concluded that it had personal jurisdiction over
    BASF Metals and ICBC. The plaintiffs argue that the LPPFC is the
    alter ego of the Fixing Members and that the district court therefore
    has personal jurisdiction over the LPPFC. We affirm the district
    court’s judgment as to personal jurisdiction over the Foreign
    Defendants.
    36
    A
    We start with the district court’s most recent holding on
    personal jurisdiction—that it had personal jurisdiction over BASF
    Metals and ICBC. Platinum II, 449 F. Supp. 3d at 327. BASF Metals and
    ICBC argue that the district court’s application of conspiracy
    jurisdiction was inconsistent with the Due Process Clause of the Fifth
    Amendment. In the context of personal jurisdiction, “due process
    demands that each defendant over whom a court exercises
    jurisdiction have some ‘minimum contacts with the forum such that
    the maintenance of the suit does not offend traditional notions of fair
    play and substantial justice.’” Schwab II, 22 F.4th at 121 (alteration
    omitted) (quoting Int’l Shoe Co. v. Washington, 
    326 U.S. 310
    , 316 (1945)).
    This inquiry usually proceeds in two steps—an analysis of whether
    each defendant has “minimum contacts” with the forum state, and an
    analysis of whether exercising jurisdiction would “comport with fair
    play and substantial justice.” Licci ex rel. Licci v. Lebanese Canadian
    Bank, SAL, 
    732 F.3d 161
    , 170 (2d Cir. 2013). We address each step, and
    we affirm.
    1
    We begin with minimum contacts. There are two types of
    personal jurisdiction: specific jurisdiction and general jurisdiction.
    Bristol-Myers Squibb Co. v. Superior Court of Cal., 
    137 S. Ct. 1773
    , 1779-
    80 (2017). Specific jurisdiction exists when a court “exercises personal
    jurisdiction over a defendant in a suit arising out of or related to the
    defendant’s contact with the forum,” and general jurisdiction “is
    based on the defendant’s general business contacts with the forum
    state and permits a court to exercise its power in a case where the
    subject matter of the suit is unrelated to those contacts.” SPV OSUS,
    37
    Ltd. v. UBS AG, 
    882 F.3d 333
    , 343 (2d Cir. 2018) (quoting Met. Life Ins.
    Co. v. Robertson-Ceco Corp., 
    84 F.3d 560
    , 567 (2d Cir. 1996)). When
    specific jurisdiction is asserted, “minimum contacts necessary to
    support such jurisdiction exist where the defendant purposefully
    availed itself of the privilege of doing business in the forum and could
    foresee being haled into court there.” Licci, 
    732 F.3d at 170
     (alteration
    omitted) (quoting Bank Brussels Lambert v. Fiddler Gonzalez &
    Rodriguez, 
    305 F.3d 120
    , 127 (2d Cir. 2002)).
    In this case, the district court employed a conspiracy theory of
    specific jurisdiction. So-called conspiracy jurisdiction “is based on the
    time-honored notion that the acts of a conspirator in furtherance of a
    conspiracy may be attributed to the other members of the
    conspiracy.” Textor v. Bd. of Regents of N. Ill. Univ., 
    711 F.2d 1387
    , 1392
    (7th Cir. 1983) (internal quotation marks and alteration omitted).
    Under that theory, “one conspirator’s minimum contacts allow for
    personal jurisdiction over a co-conspirator,” even when the
    co-conspirator lacks such contacts itself. Schwab I, 
    883 F.3d at 86
    . 8 In
    Schwab I, this court laid out three requirements for imputing the
    8 “The essence of [the conspiracy theory of personal jurisdiction] is its
    reliance on the conspiracy as an independent source of jurisdiction over a
    nonresident defendant, irrespective of his own contacts with the forum. …
    Once the court finds a conspiracy, it simply asserts its power over all
    defendants shown to be coconspirators.” Stuart M. Riback, Note, The Long
    Arm and Multiple Defendants: The Conspiracy Theory of In Personam
    Jurisdiction, 
    84 Colum. L. Rev. 506
    , 507 (1984) (footnote omitted); see also
    Alex Carver, Note, Rethinking Conspiracy Jurisdiction in Light of Stream of
    Commerce and Effects-Based Jurisdictional Principles, 
    71 Vand. L. Rev. 1333
    ,
    1337 (2018) (“Conspiracy jurisdiction is an application of specific
    jurisdiction: courts attribute the purposefully established, conspiracy-
    related forum contacts of one conspirator to a second conspirator who lacks
    such contacts.”).
    38
    minimum contacts of one co-conspirator to another: “the plaintiff
    must allege that (1) a conspiracy existed; (2) the defendant
    participated in the conspiracy; and (3) a co-conspirator’s overt acts in
    furtherance of the conspiracy had sufficient contacts with a state to
    subject that co-conspirator to jurisdiction in that state.” 
    883 F.3d at 87
    .
    In Schwab II, this court held that a complaint alleged personal
    jurisdiction under a conspiracy theory over the defendants’ objection
    that the third Schwab I factor was not met. 22 F.4th at 122. In that case,
    the plaintiffs alleged that the defendant banks had executives and
    managers in the United States who would direct subordinates to
    manipulate the LIBOR. Id. at 123. The directions took the forms of “a
    standing directive to submit low LIBOR contributions” and “emails
    between a senior [bank] executive in New York … asking the [bank’s
    LIBOR submitter] to err on the low side when setting LIBOR.” Id.
    (internal quotation marks and alteration omitted). We held that “these
    communications would establish overt acts taken by co-conspirator
    Banks in the United States in furtherance of the suppression
    conspiracy, vesting the district court with personal jurisdiction over
    each Defendant”—including those defendants who did not engage in
    such overt acts. Id.
    Our decision in Schwab II requires the conclusion that there are
    minimum contacts to establish conspiracy jurisdiction in this case.
    The plaintiffs have adequately alleged that a conspiracy existed to
    manipulate the platinum and palladium benchmark prices. “At the
    pleading stage, a complaint claiming conspiracy, to be plausible, must
    plead enough factual matter (taken as true) to suggest that an
    agreement was made.” Gelboim, 
    823 F.3d at 781
     (internal quotation
    marks omitted). We have said that allegations that “evince a common
    39
    motive to conspire” combined with “a high number of interfirm
    communications” are adequate to plead a conspiracy. 
    Id. at 781-82
    .
    Here, the plaintiffs allege that the defendants were “net short” in their
    platinum and palladium positions and that the defendants “could
    and did cash in on the foreknowledge that the Fix price, and thus the
    prices of platinum and palladium generally, was going to go down on
    a given day, at a given time.” App’x 460, 357.
    The plaintiffs allege not only a common motive but also
    numerous interfirm communications. According to the complaint, via
    the Fixing the defendants “met twice daily on … private phone
    call[s]” that “involved the direct exchange of intended or future price
    information among horizontal competitors.” Id. at 448. Interfirm
    communications included “the sharing of client orders and imminent
    orders” as well as “chat rooms, instant messages, phone calls,
    proprietary trading venues and platforms, and e-mails to coordinate
    among themselves … to ensure … that attempts to move the market
    in one way or the other were not undone (unwittingly or not) by the
    contrary efforts of other members or other large banks.” Id. at 448-49.
    Because the plaintiffs allege that BASF Metals and ICBC
    participated in a conspiracy, we have personal jurisdiction over those
    parties at this stage if “a co-conspirator’s overt acts in furtherance of
    the conspiracy had sufficient contacts with a state to subject that co-
    conspirator to jurisdiction in that state.” Schwab I, 
    883 F.3d at 87
    . That
    is not a difficult requirement to meet: “[a]n overt act is any act
    performed by any conspirator for the purpose of accomplishing the
    objectives of the conspiracy.” United States v. Lange, 
    834 F.3d 58
    , 70 (2d
    Cir. 2016) (quoting United States v. Tzolov, 
    642 F.3d 314
    , 320 (2d Cir.
    2011)). The complaint alleges that precious metals traders—based in
    40
    the United States and employed by co-conspirators of BASF and
    ICBC—“would update order information during the Fixing and
    provide this updated order information to” BASF’s and ICBC’s
    “participant[s] in the Fixing as the Fixing was conducted.” App’x 365,
    368. According to the complaint, such communications were
    necessary to “coordinate” members of the conspiracy so that the
    conspiracy’s “attempts to move the market in one way or the other
    were not undone” by individual orders. 
    Id. at 449
    . The alleged sharing
    of “client orders and imminent orders” also enabled manipulation of
    the benchmark prices because it provided the defendants “access to
    nonpublic, real-time information about changes in the price of
    platinum and palladium” and “future price information among
    horizontal competitors.” 
    Id. at 448
    . Because these communications
    occurred in the United States, the complaint in this case satisfies
    Schwab I’s third prong and our requirements for minimum contacts
    under conspiracy jurisdiction.
    BASF Metals and ICBC argue that they “could not have
    reasonably anticipated being haled into court in the United States as
    a result of participating with other London-based parties in London-
    based activity that concerned London- and Zurich-based materials.”
    Cross-Appellants’ Supp. Br. 20 (internal quotation marks and
    alteration omitted). Perhaps not. The allegations in the complaint
    might not establish that BASF Metals or ICBC themselves had
    minimum contacts with the forum state. But we have already held in
    Schwab I that “a co-conspirator’s minimum contacts … in furtherance
    of the conspiracy” fulfills the requirement that the “defendant must
    have purposefully availed itself of the privilege of doing business in
    the forum.” 
    883 F.3d at 85-87
     (emphasis added) (internal quotation
    marks omitted). Such purposeful availment is the sort of “conduct
    41
    and connection with the forum State” that should lead a defendant to
    “reasonably anticipate being haled into court there.” World-Wide
    Volkswagen Corp. v. Woodson, 
    444 U.S. 286
    , 297 (1980).
    BASF Metals and ICBC take issue with the theory of conspiracy
    jurisdiction itself, criticizing it as “hing[ing] entirely on the
    proposition that a court may legitimately impute the in-forum
    contacts of a third party to a defendant who resides outside of the
    forum.” BASF Metals’s Br. 41. Conspiracy jurisdiction, these parties
    assert, is “extraordinarily broad” because “it … permit[s] the exercise
    of personal jurisdiction over a defendant based on the actions of a
    co-conspirator who is entirely unknown to that defendant.” Id. at 46
    (internal quotation marks and alteration omitted). For these reasons,
    BASF Metals and ICBC argue that “‘conspiracy jurisdiction’ violates
    the Due Process Clause and Supreme Court precedent interpreting
    it.” Id. at 40.
    There may be grounds for those objections. Conspiracy
    jurisdiction seems to have expanded beyond its more limited roots.
    “[E]arly cases upheld jurisdiction over nonresident conspirators
    based on the in-state acts of their coconspirators, but the courts
    generally did so on the theory that the in-state coconspirators acted
    as agents of the nonresident defendants.” Carver, supra note 8, at 1340.
    In fact, Schwab II referenced agency principles in explaining
    conspiracy jurisdiction. 22 F.4th at 122 (“Much like an agent who
    operates on behalf of, and for the benefit of, its principal, a co-
    conspirator who undertakes action in furtherance of the conspiracy
    essentially operates on behalf of, and for the benefit of, each member
    of the conspiracy.”). But the argument that our exercise of conspiracy
    jurisdiction should be limited by agency principles is no longer
    42
    available. We have observed that “some control is necessary to
    establish agency for jurisdictional purposes,” CutCo Indus., Inc. v.
    Naughton, 
    806 F.2d 361
    , 366 (2d Cir. 1986) (construing New York’s
    long-arm statute), but we have squarely rejected that limitation on
    conspiracy jurisdiction, Schwab II, 22 F.4th at 125 (concluding that
    “our caselaw does not require a relationship of control, direction, or
    supervision” to establish conspiracy jurisdiction).
    In doing so, we followed the suggestion that, because “for most
    purposes the acts of one conspirator within the scope of the
    conspiracy are attributed to the others,” there is no reason “personal
    jurisdiction should be an exception.” Stauffacher v. Bennett, 
    969 F.2d 455
    , 459 (7th Cir. 1992) (Posner, J.). BASF Metals and ICBC argue that
    the minimum contacts inquiry must be more “defendant-focused”
    than the rules of conspiracy liability. BASF Metals’s Br. 41 (quoting
    Walden v. Fiore, 
    571 U.S. 277
    , 284 (2014)). Other critics of conspiracy
    jurisdiction have similarly argued that the “purposes of the law of
    civil conspiracy and the law of in personam jurisdiction” are
    “opposed.” Riback, supra note 8, at 530. On the one hand, “[a]
    conspiracy claim serves merely to expand liability for the underlying
    wrong to persons who are not directly involved in the wrongful
    actions,” 15A C.J.S. Conspiracy § 18 (2022), and is “a mechanism to aid
    the plaintiff,” Riback, supra note 8, at 530. The due process limitations
    on in personam jurisdiction, on the other hand, are meant to “give[] a
    degree of predictability to the legal system that allows potential
    defendants to structure their primary conduct with some minimum
    assurance as to where that conduct will and will not render them
    liable to suit.” World-Wide Volkswagen, 
    444 U.S. at 297
    . In other words,
    “[w]hile a solicitude for the plaintiff’s interests is central to the
    determination of conspiratorial liability, it is not so in the
    43
    determination of jurisdiction, in which the defendant is the primary
    concern.” Riback, supra note 8, at 530. Under this line of argument, the
    rules of conspiratorial liability should not govern a court’s personal
    jurisdiction over a conspirator. 9
    While we acknowledge the debate over this question, 10 our
    court has already taken a position—and we are bound to follow our
    previous decision. Glob. Reinsurance Corp. of Am. v. Century Indem. Co.,
    
    22 F.4th 83
    , 100-01 (2d Cir. 2021) (“[A] decision of a panel of this Court
    is binding unless and until it is overruled by the Court en banc or by
    the Supreme Court.”) (quoting United States v. Hightower, 
    950 F.3d 33
    ,
    36 (2d Cir. 2020)). Because this court held that minimum contacts were

    Jurisdiction: A Due Process Analysis,

    , 241 (1983)
    (criticizing courts for “fail[ing] to differentiate between the standards
    governing liability and those governing jurisdiction”); Riback, supra note 8,
    at 510 (“It is elementary that the fact of liability does not confer jurisdiction,
    yet by endowing a conspiracy with an independent jurisdictional
    significance, the conspiracy theory does just that.”) (footnote omitted).
    10See, e.g., Smith v. Jefferson Cnty. Bd. of Educ., 
    378 F. App’x 582
    , 586 (7th Cir.
    2010) (describing conspiracy jurisdiction as “a theory that is … marginal at
    best”); Chirila v. Conforte, 
    47 F. App’x 838
    , 842 (9th Cir. 2002) (“There is a
    great deal of doubt surrounding the legitimacy of this conspiracy theory of
    personal jurisdiction.”); Schwartz v. Frankenhoff, 
    733 A.2d 74
    , 80 (Vt. 1999)
    (observing that the U.S. Supreme Court’s “decisions strongly suggest” that
    “conspiracy participation is not enough” to “meet due process
    requirements for personal jurisdiction”); Nat’l Indus. Sand Ass’n v. Gibson,
    
    897 S.W.2d 769
    , 773 (Tex. 1995) (declining “to recognize the assertion of
    personal jurisdiction over a nonresident defendant based solely upon the
    effects or consequences of an alleged conspiracy with a resident in the
    forum state”).
    44
    present in Schwab II, it follows that such contacts are present for BASF
    Metals and ICBC in this case.
    2
    “If a defendant has sufficient minimum contacts,” we “must
    also determine whether the exercise of personal jurisdiction is
    reasonable under the Due Process Clause.” MacDermid, Inc. v. Deiter,
    
    702 F.3d 725
    , 730 (2d Cir. 2012). BASF Metals and ICBC argue that,
    even if minimum contacts are present in this case, “any exercise of
    specific jurisdiction … would be unreasonable.” BASF Metals’s Br. 55.
    We disagree. The reasonableness inquiry depends on five factors:
    (1) the burden that the exercise of jurisdiction will
    impose on the defendant; (2) the interests of the forum
    state in adjudicating the case; (3) the plaintiff’s interest in
    obtaining convenient and effective relief; (4) the
    interstate judicial system’s interest in obtaining the most
    efficient resolution of the controversy; and (5) the shared
    interest of the states in furthering substantive social
    policies.
    Met. Life, 
    84 F.3d at 568
    . “Where a plaintiff makes the threshold
    showing of the minimum contacts required for the first test, a
    defendant must present a compelling case that the presence of some
    other considerations would render jurisdiction unreasonable.” Bank
    Brussels Lambert, 
    305 F.3d at 129
     (internal quotation marks omitted).
    “The import of the ‘reasonableness’ inquiry varies inversely with the
    strength of the ‘minimum contacts’ showing—a strong (or weak)
    showing by the plaintiff on ‘minimum contacts’ reduces (or increases)
    the weight given to ‘reasonableness.’” 
    Id.
    BASF Metals and ICBC have not met the burden of showing
    unreasonableness. According to BASF Metals and ICBC, the burden
    45
    of being haled into court in the United States is “severe.” BASF
    Metals’s Br. 57 (quoting Asahi Metal Indus. Co. v. Super. Ct. of Cal., 
    480 U.S. 102
    , 114 (1987)). But we have previously held with respect to a
    Puerto Rican defendant sued in New York that this factor provides
    “only weak support” because “the conveniences of modern
    communication and transportation ease what would have been a
    serious burden only a few decades ago.” Bank Brussels Lambert, 
    305 F.3d at 129-30
    . Neither do BASF Metals and ICBC make the necessary
    showing on the second or third factors given New York’s interest in
    adjudicating a claim concerning manipulation on the NYMEX and the
    fact that the plaintiffs reside in the United States.
    BASF Metals and ICBC argue that the remaining factors—
    which those parties characterize as “considerations of international
    rapport,” BASF Metals’s Br. 58 (alteration omitted) (quoting Daimler
    AG v. Bauman, 
    571 U.S. 117
    , 142 (2014))—weigh against exercising
    personal jurisdiction in this case. The Supreme Court has explained
    that, in the context of an “assertion of jurisdiction over an alien
    defendant,” the fourth and fifth reasonableness factors “call[] for a
    court to consider the procedural and substantive policies of other
    nations whose interests are affected” by the exercise of personal
    jurisdiction. Asahi, 
    480 U.S. at 115
    . According to BASF Metals and
    ICBC, “[i]t is insulting to the sovereignty of foreign nations to subject
    their residents to personal jurisdiction in the United States” based on
    a conspiracy jurisdiction theory. BASF Metals’s Br. 59.
    BASF     Metals    and   ICBC      overestimate   the   weight   of
    “international rapport” in this context. That language comes from the
    Supreme Court’s decision in Daimler, which rejected the Ninth
    Circuit’s attempt to “subject[] Daimler to the general jurisdiction of
    46
    courts in California.” 571 U.S. at 142. Given the scope of general
    jurisdiction, it is unsurprising that “international rapport” would be
    harmed by “some domestic courts’ expansive views of general
    jurisdiction.” Id. at 142. The international rapport concerns of Daimler
    do not apply equally in a case, such as this one, that involves specific
    jurisdiction.
    This case is not “the ‘exceptional situation’ where exercise of
    jurisdiction is unreasonable even though minimum contacts are
    present.” Bank Brussels Lambert, 
    305 F.3d at 130
    . We affirm the district
    court’s assertion of personal jurisdiction over BASF Metals and ICBC.
    B
    We next turn to the district court’s dismissal of the LPPFC as a
    defendant. The plaintiffs expressly decline to challenge the district
    court’s holding in Platinum I that there is no conspiracy jurisdiction
    over the LPPFC and instead argue that the district court should have
    exercised personal jurisdiction under an alter ego theory of personal
    jurisdiction. We disagree and affirm.
    This court has observed that it is “well established that the
    exercise of personal jurisdiction over an alter ego corporation does not
    offend due process.” S. New Eng. Tel. Co. v. Glob. NAPs Inc., 
    624 F.3d 123
    , 138 (2d Cir. 2010). “The alter-ego theory provides for personal
    jurisdiction if the parent company exerts so much control over the
    subsidiary that the two do not exist as separate entities but are one
    and the same for purposes of jurisdiction.” Indah v. SEC, 
    661 F.3d 914
    ,
    921 (6th Cir. 2011) (internal quotation marks omitted). The usual
    application of an alter ego theory serves to extend personal
    jurisdiction over the parent company. In this case, the plaintiffs seek
    47
    to do the reverse—to extend personal jurisdiction over the Fixing
    Members to their subsidiary, the LPPFC.
    “Because we treat the parent and subsidiary as ‘not really
    separate entities’ if they satisfy the alter ego analysis, there is no
    greater justification for bringing the parent into the subsidiary’s
    forum than for doing the reverse.” Ranza v. Nike, Inc., 
    793 F.3d 1059
    ,
    1072 (9th Cir. 2015) (internal citation omitted) (quoting Doe v. Unocal
    Corp., 
    248 F.3d 915
    , 926 (9th Cir. 2001)). Accordingly, “[t]he crux of the
    alter-ego theory of personal jurisdiction” is that “courts are to look for
    two entities acting as one,” Anwar v. Dow Chem. Co., 
    876 F.3d 841
    , 848
    (6th Cir. 2017), an inquiry that we have compared to piercing the
    corporate veil, S. New Eng. Tel. Co., 
    624 F.3d at 147
    . The parties
    disagree on whether English or federal common law governs the
    question of piercing the LPPFC’s corporate veil. 11 We need not
    11In diversity cases, we look to the choice-of-law rules of the forum state to
    determine the veil-piercing law to apply. See Am. Fuel Corp. v. Utah Energy
    Dev. Co., 
    122 F.3d 130
    , 134 (2d Cir. 1997). Because the LPPFC is “organized
    and existing under the laws of the United Kingdom,” App’x 370-71, and
    New York’s rule is that “the law of the state of incorporation determines
    when the corporate form will be disregarded,” Fletcher v. Atex, Inc., 
    68 F.3d 1451
    , 1456 (2d Cir. 1995) (quoting Fletcher v. Atex, Inc., 
    861 F. Supp. 242
    , 244
    (S.D.N.Y. 1994)), under that rule English law would apply. This case,
    however, arises under federal law. Other courts have held that federal
    common law governs alter-ego theories “when a federal interest is
    implicated by the decision of whether to pierce the corporate veil.” Anwar,
    
    876 F.3d at 848-49
     (applying federal common law to an alter ego personal
    jurisdiction claim); see also United States ex rel. Small Bus. Admin. v. Pena, 
    731 F.2d 8
    , 12 (D.C. Cir. 1984) (noting that “courts ha[ve] both a jurisdictional
    and substantive basis for resorting to a federal common law of veil-
    piercing” when “some federal interest [i]s implicated by the decision
    whether to pierce the corporate veil”).
    48
    resolve that dispute because under neither approach can the plaintiffs
    succeed.
    The plaintiffs have not pleaded facts sufficient to pierce the
    corporate veil under English law. “English law … will pierce the
    corporate veil and recognize one entity as the alter ego of another only
    where special circumstances exist indicating that the relationship of
    one corporation to another is a mere facade concealing the true facts.”
    Great Lakes Overseas, Inc. v. Wah Kwong Shipping Grp., 
    990 F.2d 990
    , 997
    (7th Cir. 1993) (internal quotation marks omitted). In Great Lakes, the
    Seventh Circuit observed that English courts will not “pierc[e] the
    corporate veil to hold a parent company responsible for the debts of
    its wholly owned subsidiary even where the subsidiary was created
    to conduct the business at issue and was funded entirely by loans
    advanced by the parent.” 
    Id.
     (describing Atlas Maritime Co. SA v.
    Avalon Maritime Ltd. [1991] 4 All E.R. 769 (AC)). In this case, the
    plaintiffs argue that the district court should have pierced the
    corporate veil because the Fixing Members “selected LPPFC’s board
    members” and “conducted LPPFC’s day-to-day operations” and
    because the LPPFC “was financially dependent on” the Fixing
    Members and “had no function other than to implement the Fixing.”
    Appellants’ Br. 55-56. But the same could be said of any single-
    shareholder corporation, and “[t]he involvement of a sole or majority
    shareholder in a corporation is not sufficient alone to establish a basis
    to disregard the corporate entity and pierce the corporate veil.” 18
    C.J.S. Corporations § 21 (2022). 12 The plaintiffs have not identified any
    12See also 1 James D. Cox & Thomas L. Hazen, Treatise on the Law of
    Corporations § 7:10 (3d ed. 2021) (noting that, when courts in “veil-piercing
    cases” consider “whether the controlling stockholder has so dominated the
    49
    “special circumstances” to justify piercing the veil here. Great Lakes,
    
    990 F.2d at 997
    .
    Neither can the plaintiffs succeed on an alter ego theory under
    federal common law. The plaintiffs in this case argue that, under
    federal common law, they “need only show that Defendants
    dominated LPPFC.” Appellants’ Br. 55. The plaintiffs cite Marine
    Midland Bank, N.A. v. Miller, 
    664 F.2d 899
    , 904 (2d Cir. 1981), for the
    proposition that “veil-piercing for purposes of pleading personal
    jurisdiction is relaxed.” Appellants’ Reply Br. 58. In Marine Midland
    Bank, this court considered the “fiduciary shield doctrine,” which
    provides that “if an individual has contact with a particular state only
    by virtue of his acts as a fiduciary of the corporation, he may be
    shielded from the exercise, by that state, of jurisdiction over him
    personally on the basis of that conduct.” 
    664 F.2d at 902
    . We created
    an exception to that rule, holding that “[i]f the corporation is merely
    a shell, it is equitable, even if the shell may not have been used to
    perpetrate a fraud, to subject its owner personally to the court’s
    jurisdiction to defend the acts he has done on behalf of his shell.” 
    Id. at 903
    .
    Even if we accept that as the federal common law test for alter
    ego personal jurisdiction, the plaintiffs have not adequately alleged
    that the LPPFC is such a “shell.” We have “disregarded corporate
    formalities when a corporation’s owner exercises ‘total and exclusive
    domination of the corporation.’” S. New Eng. Tel. Co., 
    624 F.3d at 139
    (quoting Lowen v. Tower Asset Mgmt., Inc., 
    829 F.2d 1209
    , 1221 (2d Cir.
    affairs of the corporation that the corporation has no existence of its own,”
    there is usually “the additional requirement that fraud, illegality or gross
    unfairness will result if the corporate existence is not disregarded”).
    50
    1987)). For example, in Midland Bank, the plaintiffs “made a prima
    facie showing that Miller & Associates was a shell corporation” when
    it “presented deposition testimony and affidavits concerning the
    ownership, capitalization, and use by Miller of Miller & Associates”
    as well as evidence that “Miller & Associates was no more than a
    telephone number and stationery.” 
    664 F.2d at 904
    . In contrast, the
    allegations that the plaintiffs highlight on appeal—that the LPPFC
    “was financially dependent on Defendants” and “had no function
    other than to implement the Fixing” and that the defendants placed
    its employees on the LPPFC’s board, Appellants’ Br. 55-56—do not
    provide a reason to treat the LPPFC differently from any corporation
    operated by its owner. See Harris Rutsky & Co. Ins. Servs., Inc. v. Bell &
    Clements Ltd., 
    328 F.3d 1122
    , 1135 (9th Cir. 2003) (holding that “100%
    control through stock ownership” and “shar[ing] the same offices …
    and some of the same staff” did not make one company the alter ego
    of the other). 13
    As noted above, the plaintiffs did not merely fail to argue that
    we have conspiracy jurisdiction over the LPPFC but expressly
    declined to make that argument. Cross-Appellees’ Supp. Reply Br. 10
    n.7 (“Plaintiffs do not challenge the district court’s conspiracy
    jurisdiction ruling as to LPPFC.”). “[A]rguments not made in an
    13 In the third amended complaint, the plaintiffs allege that the LPPFC
    “never maintained any office space” and that “its correspondence address
    [is] at a corporate law firm.” App’x 371. At oral argument, however, the
    plaintiffs conceded that because the LPPFC is not named as a defendant in
    the third amended complaint, we “evaluate the sufficiency of the claims as
    to” the LPPFC “based on the allegations in the second amended complaint.”
    Oral Argument Audio Recording at 20:30. Because the allegations
    concerning the LPPFC’s office space are absent from the second amended
    complaint, we do not consider those allegations.
    51
    appellant’s opening brief are waived even if the appellant pursued
    those arguments in the district court or raised them in a reply brief.”
    JP Morgan Chase Bank v. Altos Hornos de Mex., S.A. de C.V., 
    412 F.3d 418
    , 428 (2d Cir. 2005). Because the plaintiffs have not adequately
    alleged that the LPPFC is the Fixing Members’ alter ego for
    jurisdictional purposes, we affirm the district court’s dismissal of
    claims against the LPPFC.
    IV
    We consider last the plaintiffs’ challenge to the district court’s
    dismissal of claims against BASF Corporation in Platinum I. The
    district court dismissed the claims against BASF Corporation under
    Rule 12(b)(6), holding that the plaintiffs’ “allegations against BASF
    Corp. do not meet even the most liberal pleading standard.”
    Platinum I, 
    2017 WL 1169626
    , at *52. According to the plaintiffs,
    however, “BASF Corp. had every incentive and opportunity to work
    closely with BASF Metals and the Fixing’s participants generally to
    further the conspiracy” and the second amended complaint’s
    allegations    “plausibly     demonstrate      [BASF      Corporation’s]
    participation in the price fixing conspiracy.” Appellants’ Br. 59. We
    disagree and affirm the district court’s judgment on this point.
    Section 1 of the Sherman Act “punishes the conspiracies at
    which it is aimed on the common law footing,—that is to say, it does
    not make the doing of any act other than the act of conspiring a
    condition of liability.” Nash v. United States, 
    229 U.S. 373
    , 378 (1913).
    In other words, “the agreement itself [is] the offense” and no overt
    acts are necessary to violate section 1. United States v. Sassi, 
    966 F.2d 283
    , 284 (7th Cir. 1992). Thus, “[a] plaintiff’s job at the pleading stage
    … is to allege enough facts to support the inference that a conspiracy
    52
    actually existed,” and that may be accomplished through either direct
    or circumstantial evidence. Mayor & Council of Balt. v. Citigroup, Inc.,
    
    709 F.3d 129
    , 136 (2d Cir. 2013). Direct evidence is rare; it “would
    consist, for example, of a recorded phone call in which two
    competitors agreed to fix prices at a certain level.” 
    Id.
     There is no
    assertion of such evidence in this case.
    “[A] complaint may, alternatively, present circumstantial facts
    supporting the inference that a conspiracy existed.” 
    Id.
     “[E]ven in the
    absence of direct ‘smoking gun’ evidence, a horizontal price-fixing
    agreement may be inferred on the basis of conscious parallelism,
    when such interdependent conduct is accompanied by circumstantial
    evidence and plus factors.” Todd v. Exxon Corp., 
    275 F.3d 191
    , 198 (2d
    Cir. 2001). Such plus factors include “a common motive to conspire,
    evidence that shows that the parallel acts were against the apparent
    individual economic self-interest of the alleged conspirators, and
    evidence of a high level of interfirm communications.” Mayor &
    Council of Balt., 706 F.3d at 136 (quoting Twombly v. Bell Atl. Corp., 
    425 F.3d 99
    , 114 (2d Cir. 2005), rev’d on other grounds, 
    550 U.S. 544
     (2007)).
    The plaintiffs have failed to allege a conspiracy that includes
    BASF Corporation. The plaintiffs’ argument relies on those parts of
    the second amended complaint which assert that BASF Corporation
    had a “common interest” in suppressing platinum and palladium
    prices. Appellants’ Br. 59. That may demonstrate a “plus factor,” but
    it does not address the primary defect of the claims against BASF
    Corporation: the second amended complaint “says nothing about
    BASF Corp.’s involvement—direct or indirect—in the alleged price
    manipulation, BASF Corp.’s role in executing the scheme, or BASF
    Corp.’s motive in artificially suppressing the Fix Price.” Platinum I,
    53
    
    2017 WL 1169626
    , at *52. Plus factors such as common motive are
    “circumstances which, when combined with parallel behavior, might
    permit a jury to infer the existence of an agreement.” Mayor & Council
    of Balt., 706 F.3d at 136 n.7. The plaintiffs in this case, however, have
    not alleged any behavior on the part of BASF Corporation at all.
    We affirm the district court’s dismissal of the claims against
    BASF Corporation.
    CONCLUSION
    We REVERSE the district court’s dismissal of the Exchange
    Plaintiffs’ antitrust claims and VACATE the district court’s dismissal
    of the plaintiffs’ CEA claims. We AFFIRM the remainder of the
    district court’s judgment, and REMAND to the district court for
    further proceedings consistent with this opinion.
