    I. INTRODUCTION
    This appeal is from a jury verdict finding Campus Village Apartments, LLC
    (Campus Village) in violation of § 2 of the Sherman Antitrust Act based on its
    participation in a conspiracy with the University of Colorado-Denver (UCD) to
    monopolize commerce. Auraria Student Housing at the Regency, LLC (Regency)
    sued Campus Village after UCD instituted a residency requirement which forced a
    significant portion of its freshmen and international students to live at Campus
    Village. Like Regency, Campus Village is an apartment complex located outside the
    boundaries of the UCD Campus. But the University of Colorado Real Estate
    Foundation (CUREF) is the sole member of Campus Village, and CUREF operates
    Campus Village for the benefit of the University of Colorado system. Although
    Regency alleges that UCD participated in the conspiracy, it named only Campus
    Village as a defendant in this litigation.
    2
    On appeal, Campus Village argues principally that the district court erred by
    not requiring Regency to define the “relevant market” Campus Village allegedly
    conspired to monopolize. Specifically, it claims recent Supreme Court and Tenth
    Circuit authority mandate that plaintiffs identify both the relevant geographic and
    product markets to recover under § 2, including for conspiracy-to-monopolize claims.
    We agree.
    Decades ago, this court determined—based on its reading of the Supreme
    Court’s decision in United States v. Yellow Cab Co., 
    332 U.S. 218
     (1947)—that § 2
    conspiracy claims did not require proof of a relevant market. Salco Corp. v. Gen.
    Motors Corp., 
    517 F.2d 567
    , 576 (10th Cir. 1975) (Salco). Intervening Supreme
    Court precedent, however, including Spectrum Sports, Inc. v. McQuillan, 
    506 U.S. 447
     (1993) (Spectrum Sports), provides new guidance for reading Yellow Cab and its
    progeny. With the benefit of this direction, we depart from our decision in Salco, and
    instead hold that plaintiffs must define the relevant market in every § 2 claim. This is
    true even though a showing of the defendants’ power in that market may not be
    required in some instances.
    Regency failed to identify the relevant market here, and Campus Village
    moved for summary judgment on that basis, among others. Constrained by our
    decision in Salco, the district court held that § 2 conspiracy claims do not require
    proof of a relevant market, and it denied Campus Village’s motion. Ultimately, the
    case went to the jury and it rendered a verdict in Regency’s favor. Because Regency
    failed to define the relevant market, we vacate the jury verdict. However, in light of
    3
    our departure from Salco, and with the additional guidance provided herein, we
    remand to the district court to provide Regency with an opportunity to prove the
    relevant market. We also affirm the district court’s rulings on Campus Village’s
    statute of limitations and state action immunity arguments.
    II. BACKGROUND
    A. Factual History
    The facts in this case are largely undisputed. On September 27, 2004, CUREF
    developed a list of “areas of responsibility” in connection with the planned
    development of student housing for UCD students. One of the “Expectations of the
    University” was that it would “[e]nact[] a residency requirement for international
    students and freshmen from outside the Denver metro area.” Two months later,
    CUREF and UCD entered into a Letter Agreement in which UCD agreed, in more
    concrete terms, to “institute a residency requirement for all full-time enrolled
    freshmen at the [UCD] downtown Denver, Colorado campus who reside outside of a
    radius of 50 miles from the [UCD] downtown Denver, Colorado campus.” This
    residency requirement provided security for the bond offering used to fund the
    construction of Campus Village, thereby making the offering more appealing to
    investors. And the parties agree the requirement increased out-of-state student
    enrollment. It is disputed, however, whether the residency requirement was instituted
    for the purpose of increasing out-of-state freshmen enrollment, retention rates, and
    student quality of life, or whether it was done purely to assist in the issuance of the
    bonds.
    4
    The residency requirement was officially approved on November 22, 2005, to
    be instituted in Fall 2006.1 Although the Letter Agreement made mention of a 50-
    mile exemption for freshmen students, the requirement as promulgated was slightly
    different. It instead stated: “[UCD] requires all first time [UCD] freshmen under the
    age of 21 not living with their parent(s) or legal guardian(s), to live in the Campus
    Village Apartments.” But it provided a few exemptions, including for “undergraduate
    student[s] enrolled for less than 10 credit hours per semester.” UCD continued to
    enforce this requirement and in a 2008 Operating Agreement, “[UCD] agree[d] to
    continue the implementation and enforcement of its policy requiring first time
    freshman and international students to reside in the Apartments, subject to the agreed
    upon exceptions.” And UCD specifically advertised that “students may NOT live at
    the Inn at Auraria or the Regency,” two apartment complexes within close proximity
    to Campus Village.
    In 2010, UCD made some changes to the residency requirement. In particular,
    there was no longer an exemption for students enrolled in fewer than 10 course hours,
    thereby increasing the number of freshmen students required to live at Campus
    Village.
    1
    Regency has suggested that this requirement is particularly egregious because
    students are notified of the requirement only after admission. But although a
    “handful” of students each year “fell through the cracks” and decided to live at the
    Regency, there is nothing in the record to suggest that these students did so based on
    UCD’s failure to inform. Rather, UCD publicized the requirement on its website and
    reached out to all affected students from the requirement’s inception.
    5
    B. Procedural History
    Regency filed its complaint on October 14, 2010, alleging Campus Village
    conspired with UCD to monopolize commerce, in violation of § 2 of the Sherman
    Antitrust Act. Regency also raised other claims for relief under Colorado state law,
    including civil conspiracy and interference with business relations. In turn, Campus
    Village filed a motion to dismiss under Fed. R. Civ. P. 12(b)(6), arguing among other
    things that Regency’s § 2 claim was barred by state action immunity due to UCD’s
    involvement in the project. The district court denied Campus Village’s motion to
    dismiss. Campus Village filed an immediate appeal, which this court dismissed for
    lack of jurisdiction because it was not from a final order. Auraria Student Hous. at
    the Regency, LLC v. Campus Vill. Apartments, LLC, 
    703 F.3d 1147
     (10th Cir. 2013).
    Campus Village then filed a motion for summary judgment, characterizing the
    residency requirement as “simply a tying arrangement,” whereby certain consumers
    of college education at UCD also were required to purchase housing from Campus
    Village. Campus Village also argued that Regency failed to show harm to
    competition, as required under § 2, because it had “no evidence that UCD . . . has
    market power [in the higher education market] or operates in a non-competitive
    market.” Regency denied the challenged conduct was a tying arrangement, arguing
    that “[a] key difference is that tying requires a relevant market; conspiracy to
    monopolize does not.” The district court denied the motion, treating Campus
    Village’s tying arrangement argument as an unsupported “affirmative defense.”
    Campus Village filed a motion to reconsider, stressing again that the focus of § 2 is
    6
    on harm to competition, regardless of the nature of the conduct, and that it had “met
    its burden on summary judgment by pointing out that the plaintiff has no evidence of
    market power.” The district court denied this motion as well, and the case proceeded
    to trial.
    After the close of Regency’s case, Campus Village submitted an oral motion
    under Rule 50(a) for judgment as a matter of law. The district court granted the
    motion as to Regency’s state-law claims, but it denied the motion as to Regency’s § 2
    claim. In particular, the court found Regency had submitted sufficient evidence of
    Campus Village’s intent to monopolize. It also ruled Regency’s § 2 claim was not
    barred by the four-year statute of limitations, as the “continuing conspiracy”
    exception applied to reset the limitations period at the beginning of each school year.
    The court then submitted the case to the jury and it returned a verdict against Campus
    Village, awarding Regency $3,261,000.00 in damages, which were trebled under 
    15 U.S.C. § 15
    (a). Campus Village then filed a motion under Rule 50(b), raising
    sufficiency of the evidence arguments and renewing its argument that the suit was
    barred by state action immunity and the statute of limitations. After the district court
    denied this motion, Campus Village appealed. Exercising jurisdiction under 
    28 U.S.C. § 1291
    , we vacate the jury verdict and remand.
    III. RELEVANT MARKET REQUIREMENT
    The district court denied Campus Village’s motion for summary judgment
    despite Regency’s failure to define the relevant market in which Campus Village’s
    7
    conduct allegedly harmed competition, and it did so based on this court’s prior
    precedent in Salco. We now conclude that the rationale supporting the decision in
    Salco has been undermined by intervening authority from the Supreme Court. We
    next determine that Regency was required to identify the relevant market to pursue
    its § 2 conspiracy claim.
    In providing our reasoning for this decision, we proceed in two parts. In part
    one, we determine that identification of the relevant market is required in a
    conspiracy-to-monopolize claim under § 2. We begin with an overview of the
    Sherman Act and the evolution of the legal decisions implementing § 2 of that
    statute. Our discussion explores Supreme Court precedent interpreting what it means
    under § 2 to monopolize “any part” of commerce, as well as this circuit’s attempt to
    implement those decisions. In particular, we examine the impact of the Supreme
    Court’s opinion in Spectrum Sports on our reading of prior authority from the Court,
    including its decision in Yellow Cab. Examining these cases through the lens
    provided by Spectrum Sports, we conclude first that Yellow Cab did not dispense
    with the market requirement in § 2 conspiracy cases. We then pause to examine the
    treatment of relevant market evidence by other federal circuits in the § 2 context,
    including their implementation of the Spectrum Sports analysis. That review indicates
    that our interpretation of Spectrum Sports is consistent with decisions from the
    majority of federal circuits to have considered the issue. We then conclude that the
    requirement of market identification in conspiracy-to-monopolize cases is consistent
    with the language of § 2 generally, as well as the goals of the Sherman Act.
    8
    Ultimately, we hold that, after Spectrum Sports, the proper reading of § 2 is that
    plaintiffs must always identify the relevant market, including for conspiracy-to-
    monopolize claims. Having reached that conclusion, we next consider whether this
    panel can depart from the circuit’s contrary holding in Salco. Because the Supreme
    Court has now adopted reasoning that requires a different result than we reached
    there, we determine that this panel is not bound by Salco.
    Proceeding next to part two of this opinion, we conclude that Regency has not
    properly defined a relevant market. To begin our analysis of this issue, we discuss the
    method for defining the relevant market under the antitrust laws. We then review the
    “any part” of commerce identified by Regency and conclude that it does not properly
    identify the relevant market. However, given our new departure from Salco, we
    remand the case to provide Regency with an opportunity to properly define the
    relevant market. We also provide further guidance to the district court on remand,
    including direction on the significance of the nature of the conduct at issue to the § 2
    analysis. Accordingly, we vacate the jury verdict and remand for further proceedings
    consistent with this decision.
    PART ONE: Identification of the Relevant Market is Required in all § 2 Claims
    A. The Sherman Act
    Section 1 of the Sherman Act declares illegal “[e]very contract, combination in
    the form of trust or otherwise, or conspiracy, in restraint of trade or commerce.” 
    15 U.S.C. § 1
    . Section 2 makes it unlawful for any person to “monopolize, or attempt to
    monopolize, or combine or conspire with any other person or persons, to monopolize
    9
    any part of the trade or commerce.” 
    Id.
     § 2. Importantly, both sections of the Act
    prohibit only conduct that is harmful to competition. Section 1 does so by examining
    the particular conduct involved to determine whether it is “manifestly
    anticompetitive,” and therefore, per se illegal, or whether, through a rule of reason
    analysis, it imposes an “unreasonable restraint on competition.” Cont’l T.V., Inc. v.
    GTE Sylvania Inc., 
    433 U.S. 36
    , 49, 50 (1977); Gregory v. Fort Bridger Rendezvous
    Ass’n, 
    448 F.3d 1195
    , 1203 (10th Cir. 2006). By contrast, § 2 focuses on a narrower
    class of anticompetitive conduct—that which is monopolistic. And it does so for
    monopolization and attempt-to-monopolize claims by requiring a showing that a
    defendant’s conduct “actually monopolizes or dangerously threatens to do so.”
    Spectrum Sports, Inc. v. McQuillan, 
    506 U.S. 447
    , 459 (1993). With respect to
    attempt-to-monopolize and conspiracy claims, the statute requires a plaintiff to show
    that the defendant(s) engaged in conduct with the specific intent “to monopolize any
    part of the trade or commerce.” 
    15 U.S.C. § 2
     (emphasis added). And as to
    conspiracy claims specifically, while the defendants generally must hold some power
    in the relevant market, the plaintiff need not prove that the conspiracy resulted in a
    dangerous threat of achieving monopoly power. See U.S. Steel Corp. v. Fortner
    Enters., Inc., 
    429 U.S. 610
    , 612 n.1 (1977) (“No inference of intent to monopolize
    [on a § 2 conspiracy claim] can be drawn from the fact that a firm with a small
    market share has engaged in nonpredatory competitive conduct in the hope of
    increasing sales.”).
    10
    In sum, plaintiffs raising conspiracy-to-monopolize claims under § 2 must
    show the existence of a conspiracy, an overt act in furtherance of the conspiracy, and
    the specific intent to monopolize. And as we demonstrate below, plaintiffs must
    identify the relevant market they allege the defendants conspired to monopolize—
    both as a function of the “any part” language of the statute and to show that the aim
    of the defendants’ conduct was “to monopolize.” Id. If the defendants jointly possess
    monopoly power within that market, it may be that the “necessary and direct result”
    of the conduct was monopolization, even if the conduct considered in isolation is not
    predatory or otherwise competitively unreasonable. United States v. Griffith, 
    334 U.S. 100
    , 106 (1948), disapproved of on other grounds by Copperweld Corp. v.
    Indep. Tube Corp., 
    467 U.S. 752
     (1984); William C. Holmes, Conspiracies to
    Monopolize: A Decisional Model, 42 Ohio St. L. J. 733, 740–41 (1981). But if the
    defendants possessed little to no power within the relevant market, the specific nature
    of their conduct takes on heightened importance and must be considered jointly with
    the defendants’ proposed competitive justifications. But before turning to this issue,
    we first explain in some detail the Supreme Court’s past and present interpretation of
    the “any part” language from § 2, as it will help contextualize our necessary
    departure from Salco.
    11
    B. From Yellow Cab to Spectrum Sports: The Development of Supreme Court and
    Tenth Circuit Precedent on the Relevant Market Requirement
    1. Yellow Cab
    To begin, we must reach back to the Supreme Court’s early interpretation of
    the “any part of . . . commerce” language of § 2 in United States v. Yellow Cab Co., a
    case in which the government filed suit against several taxicab companies, claiming
    they had conspired to monopolize the markets for (1) the sale, and (2) the operation
    of taxicabs. 
    332 U.S. 218
    , 225–26 (1947), overruled on other grounds by
    Copperweld, 
    467 U.S. 752
    . The Court made two relevant observations of the “any
    part” language from § 2. First, it noted that § 2 does not “specify[] how large a part
    [of the trade or commerce] must be affected,” and it then concluded that a plaintiff
    need only allege that “some appreciable part of interstate commerce is the subject of
    a monopoly, a restraint or a conspiracy.” Id. at 225. Second, the Court found to be
    “irrelevant” the “importance of the interstate commerce affected in relation to the
    entire amount of that type of commerce in the United States.” Id. at 226. In light of
    these observations, especially the Supreme Court’s conclusion that a party need only
    allege an impact on “some appreciable part of interstate commerce,” id. at 225
    (emphasis added), a number of courts questioned whether plaintiffs raising § 2
    conspiracy claims must define a relevant market, as opposed to simply alleging an
    impact on a quantifiable amount of interstate commerce.
    12
    2. Salco and its Progeny
    In 1975, this court answered that question in the negative. Salco Corp. v. Gen.
    Motors Corp., 
    517 F.2d 567
     (10th Cir. 1975). In Salco, we interpreted Yellow Cab to
    specifically dispense with a relevant market requirement for § 2 conspiracy claims.
    Like the Supreme Court in Yellow Cab, we focused on the scope of the “any part”
    language and explained:
    Section 2 makes it unlawful to conspire to monopolize “any part” of
    interstate commerce. Specific intent to monopolize is the heart of a
    conspiracy charge, and a plaintiff is not required to prove what is the
    “relevant market.” It is enough if “‘some appreciable part of interstate
    commerce is the subject’ of the conspiracy.”
    Id. at 576 (quoting Yellow Cab, 
    332 U.S. at
    225–26). And this circuit consistently
    ruled for decades after Salco that § 2 conspiracy claims do not require proof of a
    relevant market. See, e.g., Lantec, Inc. v. Novell, Inc., 
    306 F.3d 1003
    , 1024 n.10
    (10th Cir. 2002) (vertical merger and leveraging); Monument Builders of Greater
    Kan. City, Inc. v. Am. Cemetery Ass’n. of Kan., 
    891 F.2d 1473
    , 1484 (10th Cir. 1989)
    (tying arrangement); Olsen v. Progressive Music Supply, Inc., 
    703 F.2d 432
    , 438
    (10th Cir. 1983) (price-fixing, boycott, and exclusive dealing allegations); Perington
    Wholesale, Inc. v. Burger King Corp., 
    631 F.2d 1369
    , 1377 (10th Cir. 1979)
    (exclusionary conduct).
    Based on subsequent authority from the Supreme Court, however, this court
    has since questioned Salco’s reasoning. In Lantec, we recognized a circuit split on
    whether proof of the relevant market is required to support a § 2 conspiracy claim.
    
    306 F.3d at
    1024 n.10. But in light of Salco, and because the parties had not argued
    13
    that intervening authority indicated proof of a relevant market should be required, the
    panel in Lantec decided “not [to] revisit [the] rule.” 
    Id.
     More recently, we seem to
    have deviated from Salco. The panel in Campfield v. State Farm Mutual Auto
    Insurance Co., without distinguishing between the plaintiff’s conspiracy-to-
    monopolize and monopoly claims under § 2, and without mentioning either Salco or
    the Supreme Court’s then-recent decision in Spectrum Sports, explained, “To state a
    cause of action for conduct prohibited under § 2 of the Sherman Act, the plaintiff
    must define a relevant market within which the defendants allegedly engaged in
    anticompetitive behavior.” 
    532 F.3d 1111
    , 1117 (10th Cir. 2008). The panel then
    went on to hold that, “By failing to allege an appropriate market, Mr. Campfield has
    failed to state a claim under § 2 of the Sherman Act.” Id. at 1119.
    But even if Campfield can be read to require proof of a relevant market for § 2
    conspiracy claims, we are still faced with a contrary determination in Salco. And
    “when faced with an intra-circuit conflict, a panel should follow earlier, settled
    precedent over a subsequent deviation therefrom.” King of the Mountain Sports, Inc.
    v. Chrysler Corp., 
    185 F.3d 1084
    , 1089 n.1 (10th Cir. 1999) (citation omitted). This
    would appear to be the end of our inquiry, as a three-judge panel is bound to follow
    circuit precedent. United States v. Spedalieri, 
    910 F.2d 707
    , 710 n.3 (10th Cir. 1990).
    But an exception to our rule exists where the Supreme Court has subsequently issued
    a decision that undermines our prior precedent. United States v. Hathaway, 
    318 F.3d 1001
    , 1006 (10th Cir. 2003). Just such a decision exists here.
    14
    3. Spectrum Sports
    In 1993, the Supreme Court decided Spectrum Sports, which again addressed
    the scope of the “any part” language in § 2. There, the Supreme Court reversed the
    Ninth Circuit’s holding that a plaintiff raising a § 2 attempt-to-monopolize claim
    need not define a relevant market or show the defendant’s power in that market. 
    506 U.S. at
    459–60. The Ninth Circuit had relied on its earlier decision in Lessig v.
    Tidewater Oil Co., which held that a relevant antitrust market is “not in issue” in
    attempt and conspiracy cases because “Section 2 prohibits attempts to monopolize
    ‘any part’ of commerce, and a dominant position in the business . . . was not
    necessarily prerequisite to ability to attempt to monopolize an appreciable segment of
    interstate sales.” 
    327 F.2d 459
    , 474–75 (9th Cir. 1964), abrogated by Spectrum
    Sports, 
    506 U.S. 447
    . Lessig, like Salco, relied on a reading of Yellow Cab that
    deemed the alleged monopolist’s relative power in the market irrelevant, so long as
    anticompetitive activity affects “an appreciable segment of interstate sales.” 
    Id.
     at
    475 & n.48 (citing Yellow Cab, 
    332 U.S. at 226
    ).
    In rejecting Lessig’s interpretation of § 2, the Supreme Court clarified that its
    decision in Yellow Cab “relied on the ‘any part’ language to support the proposition
    that it is immaterial how large an amount of interstate trade is affected, or how
    important that part of commerce is in relation to the entire amount of that type of
    commerce in the Nation.” Spectrum Sports, 
    506 U.S. at
    457 n.9. That is, whether
    activity falls within the interstate commerce reach of the Sherman Act is based on the
    interstate character of the commerce, not on the actors’ share of a particular interstate
    15
    market. Thus, Lessig’s reliance on Yellow Cab as support for the idea that a
    defendant’s relative power in the market is irrelevant to other elements of a § 2 claim
    was misplaced. Turning to the language of the Sherman Act, the Court in Spectrum
    Sports explained that the “any part” clause in § 2 “applies to charges of
    monopolization as well as to attempts to monopolize, and it is beyond doubt that the
    former requires proof of market power in a relevant market.” Id. at 457. It
    accordingly reversed the Ninth Circuit decision and held that proof of power in a
    relevant market is necessary to establish the dangerous probability of success element
    of a § 2 attempt-to-monopolize claim.
    Although Spectrum Sports does not expressly address § 2 conspiracy-to-
    monopolize claims and such claims do not require a dangerous probability of success,
    it nevertheless undermines our decision in Salco in three ways. First, Spectrum Sports
    clarifies that Yellow Cab did not deem market identification to be irrelevant to § 2
    issues generally, thereby demonstrating that Salco’s reliance on Yellow Cab in
    support of that proposition was misplaced.2 Second, the Court’s plain language
    reading of the statute applies with equal force to conspiracy claims. Recall that § 2
    makes it unlawful for any person to “monopolize, or attempt to monopolize, or
    2
    Salco also cited United States v. Consolidated Laundries Corp., 
    291 F.2d 563
    (2d Cir. 1961). However, Consolidated Laundries also traces its rule back to Yellow
    Cab. 
    Id. at 573
     (“But where the charge is conspiracy to monopolize, the essential
    element is not the power, but the specific intent, to monopolize. Section 2 makes it
    unlawful ‘to conspire to monopolize “any part” of interstate commerce, without
    specifying how large a part must be affected. Hence it is enough if some appreciable
    part of interstate commerce is the subject’ of the conspiracy.” (quoting Yellow Cab,
    
    332 U.S. at
    225–26)).
    16
    combine or conspire with any other person or persons, to monopolize any part of the
    trade or commerce.” 
    15 U.S.C. § 2
    . The Court noted that “[t]he ‘any part’ clause . . .
    applies to charges of monopolization as well as to attempts to monopolize, and it is
    beyond doubt that the former requires proof of market power in a relevant market.”
    Spectrum Sports, 
    506 U.S. at 457
    . As is evident from the text of the statute, the “any
    part” language also applies to conspiracy-to-monopolize claims. It is equally
    apparent, then, that the “any part” language does not excuse a plaintiff in a
    conspiracy-to-monopolize case from identifying the relevant market. Third, Spectrum
    Sports reiterates that § 2 forbids only conduct which is truly anticompetitive:
    The purpose of the Act is not to protect businesses from the working of
    the market; it is to protect the public from the failure of the market. The
    law directs itself not against conduct which is competitive, even
    severely so, but against conduct which unfairly tends to destroy
    competition itself.
    
    506 U.S. at 458
    . To determine whether conduct is anticompetitive, of course,
    generally requires reference to the impact of that conduct on the relevant market. See
    NYNEX Corp. v. Discon, Inc., 
    525 U.S. 128
    , 139 (1998) (explaining that unless the
    defendants’ actions “harmed the competitive process, they did not amount to a
    conspiracy to monopolize” (emphasis added)). And we have said as much in cases
    post-dating both Salco and Lantec. See, e.g., Gregory, 
    448 F.3d at 1206
     (“Because
    the [plaintiffs] fail to establish that the [defendant’s] challenged conduct harmed the
    competitive process under § 1, their conspiracy to monopolize claim under § 2
    likewise fails.”).
    17
    4. Yellow Cab Revisited
    When examined through the lens provided by the Supreme Court in Spectrum
    Sports, the decision in Yellow Cab cannot sustain a reading that dispenses with
    market identification in conspiracy-to-monopolize cases. This new perspective on
    Yellow Cab also harmonizes it with prior and subsequent Supreme Court precedents
    that clarify the scope of the “any part” language from § 2. And it is consistent with
    the goals of the antitrust laws.
    As discussed, the Supreme Court’s statement in Yellow Cab that only an
    “appreciable part” of commerce need be affected by the conspiracy was made in
    response to the suggestion that the Sherman Act reached only conduct that had
    affected a quantifiable threshold “amount” of commerce in the whole United States.
    
    332 U.S. at 225
     (noting that § 1 “outlaws unreasonable restraints on interstate
    commerce, regardless of the amount of commerce affected” and § 2 “makes it
    unlawful to conspire to monopolize ‘any part’ of interstate commerce, without
    specifying how large a part must be affected”). The Court explained that it is enough
    to satisfy the interstate prerequisite “if some appreciable part of interstate commerce
    is the subject of a monopoly, a restraint or a conspiracy,” because the focus of both
    sections is on the interstate character of the defendant’s conduct, rather than the
    “amount” of commerce thereby affected. Id. Thus, when the Court in Yellow Cab
    declared “irrelevant” the size of the affected part of interstate commerce in relation to
    the entire volume of that type of commerce nationwide, it meant for purposes of
    establishing the interstate character of the affected commerce. Id. at 226.
    18
    Further support for a reading of Yellow Cab that does not dispense altogether
    with the relevant market requirement is its direction that such “parts” of commerce
    can be distinguished from the whole by reference to the “geographical and
    distributive significance” of §§ 1 and 2, a phrase it drew from its prior decision in
    Standard Oil. See id. at 226 (quoting Ind. Farmer’s Guide Publ’g Co. v. Prairie
    Farmer Publ’g Co., 
    293 U.S. 268
    , 279 (1934)). There, the Supreme Court explained:
    The commerce referred to by the words “[any] part,” construed in the
    light of the manifest purpose of the statute, has both a geographical and
    a distributive significance; that is, it includes any portion of the United
    States and any one of the classes of things forming a part of interstate or
    foreign commerce.
    Standard Oil Co. of N.J. v. United States, 
    221 U.S. 1
    , 61 (1911). In other words, and
    as Spectrum Sports now underscores, when § 2 uses the phrase “any part” of
    commerce, it is referring both to a geographic market and a distributive (or product)
    market—i.e., it is referring to the “relevant market.” See United States v. E.I. du Pont
    de Nemours & Co., 
    351 U.S. 377
    , 394 (1956) (expounding on the contours of the
    relevant market requirement under § 2); Bacchus Indus., Inc. v. Arvin Indus., Inc.,
    
    939 F.2d 887
    , 893 (10th Cir. 1991) (“[T]he plaintiff must prove . . . [the] relevant
    market (including geographic market and relevant product market) in which the
    alleged [antitrust violation] occurred.” (internal quotation marks omitted)).
    And although the discussion in Yellow Cab made no mention of the “specific
    intent to monopolize” element of § 2 conspiracy claims, the Court later explained that
    market power may have bearing on this element, particularly where a defendant’s
    conduct cannot be viewed as predatory. See U.S. Steel Corp. v. Fortner Enters., Inc.,
    19
    
    429 U.S. 610
    , 612 n.1 (1977) (“No inference of intent to monopolize [on a § 2
    conspiracy claim] can be drawn from the fact that a firm with a small market share
    has engaged in nonpredatory competitive conduct in the hope of increasing sales.”).
    In summary, based on the elucidation provided by the Court in Spectrum Sports, we
    conclude that Salco’s reading of Yellow Cab to eliminate a relevant market
    requirement for conspiracy claims under § 2 is flawed, and that the “any part”
    language in the statute does not dispense with the need to do so.3
    C. This View is Consistent with the Language and Purpose of the Statute and the
    Conclusion of the Majority of Circuits to Consider the Issue
    1. The Language and Goals of the Sherman Act
    A requirement that the plaintiff identify the relevant market to support all § 2
    claims gives full effect to the language of the Sherman Act. First, it provides a
    consistent interpretation of the “any part” language, and it incorporates the
    3
    The Supreme Court’s decision in United States v. Grinnell Corp., 
    384 U.S. 563
     (1966), reinforces this point by reading the “any part” language in the Act as a
    reference to the relevant market requirement. In Grinnell, the government charged
    several alarm and protective services businesses with violations of §§ 1 and 2 of the
    Sherman Act. The district court accepted the market definition of “the accredited
    central protective service business,” which was a conglomeration of the defendants’
    services. See United States v. Grinnell Corp., 
    236 F. Supp. 244
    , 249 (D.R.I. 1964),
    aff’d in part, rev’d in part, 
    384 U.S. 563
     (1966). The defendants challenged that
    market definition on certiorari, but the Supreme Court affirmed. The Court explained
    that the market for reasonably interchangeable goods “make[s] up that ‘part’ of trade
    or commerce which § 2 protects against monopoly power.” Id. at 571. In other words,
    the “any part” language from § 2 speaks to the relevant market (reasonably
    interchangeable goods), and is not simply a requirement that a defendant’s actions
    impact some appreciable amount of interstate commerce. Although the Court made
    this statement in describing the elements of “[t]he offense of monopoly under § 2,”
    id. at 570, it affirmed the district court’s definition of the relevant market as to all of
    the government’s § 2 claims, including conspiracy. See id. at 570–73; 
    236 F. Supp. at 257
    .
    20
    geographic and distributive significance of the Act. It is also consistent with § 2’s
    focus on monopolization. Recall that none of the offenses under § 2, including
    attempt and conspiracy, penalize anticompetitive conduct in the abstract. Rather, the
    statute makes it illegal to “monopolize, or attempt to monopolize, or combine or
    conspire with any other person or persons, to monopolize” a part of commerce. 
    15 U.S.C. § 2
    . As the leading antitrust treatise explains:
    [T]he statutory language itself focuses on “monopolize,” and
    “monopoly” in common usage and in common law refers to control over
    a distinct trade or calling—that is, to an economic market. The very
    concept of “monopoly” so implies. Thus, “any part of . . . trade or
    commerce” can and should be read as referring to markets in the
    economic sense.
    Phillip E. Areeda & Herbert Hovenkamp, Antitrust Law ¶ 802b (4th ed. 2015); Janis
    L. Harwell, Comment, The Relevant Market Concept in Conspiracy to Monopolize
    Cases Under Section 2 of the Sherman Act, 
    44 U. Chi. L. Rev. 805
    , 809 (1977) (“The
    relevant market requirement derives not from the ‘any part’ language of section 2 but
    rather from the term ‘monopolize.’”); see Howard Hess Dental Labs. Inc. v. Dentsply
    Int’l, Inc., 
    602 F.3d 237
    , 257 (3d Cir. 2010) (explaining that a defendant must have
    “intended to achieve an illegal monopoly” (citation omitted)).
    Second, requiring identification of the relevant market furthers the goals of the
    statute by ensuring that joint conduct is proscribed only when it is anticompetitive.
    Viewed without the context of a relevant market, a § 2 conspiracy-to-monopolize
    claim could be used to target conduct deemed pro-competitive under § 1:
    Where the agreements involved would also be held to offend §1 without
    the necessity of proving [market] power, the failure to require it for the
    21
    §2 conspiracy offense is understandable. However, in those instances
    where power is a prerequisite to holding an agreement to be an
    unreasonable restraint of trade . . . it would make no sense to hold the
    same agreement offensive to §2 without proof of power. To require
    power under §1 before condemning a particular agreement is necessarily
    to say that the arrangement is socially desirable, or at least not harmful,
    in the absence of power. That policy conclusion cannot sensibly be
    avoided or negated by the simple trick of calling the agreement a
    conspiracy to monopolize.
    Areeda & Hovenkamp ¶ 809; see also id. ¶ 802b (reading the “any part” language to
    encompass any aggregation of sales would “condemn[] every improper act by
    powerless actors as monopolization” and “would produce surprising and undesirable
    results that would make no policy sense today and that were not within congressional
    contemplation”); accord Dickson v. Microsoft Corp., 
    309 F.3d 193
    , 211 (4th Cir.
    2002). As we explain in more detail below, this danger becomes particularly acute
    where, as here, a plaintiff raises only a § 2 conspiracy claim in a likely attempt to
    obviate the market analysis that would be required for the same conduct under § 1.
    To avoid that result, we follow the Supreme Court’s rationale in Spectrum
    Sports and conclude that plaintiffs must define the relevant market in every § 2
    claim, including conspiracy-to-monopolize claims. See 
    506 U.S. at 458
     (“The law
    directs itself not against conduct which is competitive, even severely so, but against
    conduct which unfairly tends to destroy competition itself.”); Gregory, 
    448 F.3d at 1206
     (“Because the [plaintiffs] fail to establish that the [defendant’s] challenged
    conduct harmed the competitive process under § 1, their conspiracy to monopolize
    claim under § 2 likewise fails.”); Lantec, 
    306 F.3d at 1030
     (concluding that “obvious
    pro-competitive justification[s]” for firm’s conduct precluded the court from finding
    22
    a conspiracy to monopolize). As we explain below, proof of the defendants’ power in
    that market may not be required where their conduct is predatory or competitively
    unreasonable. But even in those instances, the specific intent to monopolize must be
    assessed in the context of the target market.
    2. Most Circuits Share this View
    A clear majority of federal circuits have required plaintiffs raising conspiracy
    claims under § 2 to identify the relevant market. And an increasing number have
    done so in response to the Supreme Court’s decision in Spectrum Sports.4 There is
    some variation, however, in implementation of this market requirement.
    First, at least nine circuits have required either that plaintiffs define the
    relevant market as a necessary element of a § 2 conspiracy claim, or that they
    identify, in a less rigorous fashion, the geographic and product context in which the
    conspiracy was alleged to have operated.5 Second, the Supreme Court and at least six

    power is required in conspiracy cases.”); Julian O. von Kalinowski et al., Antitrust

    D. This Panel is not Bound by Salco
    Having concluded that current guidance from the Supreme Court indicates that
    § 2 plaintiffs must identify the relevant market, we now consider whether Spectrum
    Sports constitutes “intervening” precedent sufficient to justify this panel’s departure
    from Salco. Regency argues that Spectrum Sports is not “intervening” precedent
    because Lantec, which Regency claims reaffirmed Salco, was decided after Spectrum
    Sports. But the panel in Lantec never mentioned Spectrum Sports, so the fact that
    Lantec was decided after Spectrum Sports is of no moment. “Questions which merely
    lurk in the record, neither brought to the attention of the court nor ruled upon, are not
    to be considered as having been so decided as to constitute precedents.” Webster v.
    Fall, 
    266 U.S. 507
    , 511 (1925); Merrifield v. Bd. of Cty. Comm’rs for Cty. of Santa
    Fe, 
    654 F.3d 1073
    , 1084 (10th Cir. 2011) (“It is elementary that an opinion is not
    binding precedent on an issue it did not address.”). Lantec therefore lacks any
    precedential effect on the question of Salco’s continued validity after Spectrum
    Sports. As a result, we undertake initial consideration of that issue here.
    Weighing against the significance of Spectrum Sports on this issue is the fact
    the Court there discussed attempt-to-monopolize claims, without expressly
    addressing conspiracy-to-monopolize claims. On the other hand and contrary to
    Regency’s position, the Court’s analysis applies to § 2 claims generally. As we have
    explained, the Court in Spectrum Sports elucidates the “collective message” of
    Yellow Cab and its progeny, such that those cases no longer support our analysis in
    Salco. As a result, we may depart from Salco—at least to the extent that it omits
    27
    identification of the relevant market from the elements necessary to prove a
    conspiracy-to-monopolize claim under § 2. Compare Barnes v. United States, 
    776 F.3d 1134
    , 1147 (10th Cir. 2015) (refusing to overrule prior precedent from our
    circuit because the “collective message” from intervening, related Supreme Court
    authority was not “so indisputable and pellucid . . . that it constitutes intervening
    (i.e., superseding) law that would permit us to hold (without en banc consideration)”
    to the contrary), cert. denied, 
    136 S. Ct. 1155
     (2016), with United States v. Brooks,
    
    751 F.3d 1204
    , 1209–10 (10th Cir. 2014) (“The question, however, is not whether an
    intervening Supreme Court case is on all fours with our precedent, but rather whether
    the subsequent Supreme Court decision contradicts or invalidates our prior
    analysis.”).
    In summary, when read with the advantage of the Court’s Spectrum Sports
    decision, Supreme Court precedents, including Yellow Cab, reject a reading of § 2
    that dispenses with the need to identify the relevant market for conspiracy claims.
    These precedents undermine the rationale of our decision in Salco and warrant our
    retreat from its holding. Accordingly, we depart from Salco now and instead hold that
    a plaintiff asserting a conspiracy-to-monopolize claim must identify the market the
    defendants allegedly conspired to monopolize.
    E. While Identification of the Relevant Market is Necessary, Showing the
    Defendant’s Relative Power Within that Market May Not Always be Required
    Our holding that a § 2 plaintiff must identify the relevant market does not
    mean that in every instance proof of the defendant’s power in that market is also
    28
    necessary. As discussed, § 2 conspiracy claims require a different showing than is
    required for § 2 monopolization and attempt claims. Am. Tobacco Co. v. United
    States, 
    328 U.S. 781
    , 789 (1946) (explaining, in the context of a § 2 conspiracy to
    monopolize claim, that “a conspiracy to commit a crime is a different offense from
    the crime that is the object of the conspiracy” (internal quotation marks omitted)).
    Monopolization and attempt claims under § 2 require proof that a defendant’s
    conduct “actually monopolizes or dangerously threatens to do so.” Spectrum Sports,
    
    506 U.S. at 459
    . In contrast, defendants might be “convicted . . . of a conspiracy to
    monopolize without ever having acquired the power to carry out the object of the
    conspiracy, i.e., to exclude actual and potential competitors” from the relevant
    market. Am. Tobacco Co., 
    328 U.S. at 789
    . But the Supreme Court has also explained
    that, “[n]o inference of intent to monopolize can be drawn from the fact that a firm
    with a small market share has engaged in nonpredatory competitive conduct in the
    hope of increasing sales.” U.S. Steel Corp., 
    429 U.S. at
    612 n.1.
    So, while it may not be necessary for plaintiffs in § 2 conspiracy claims to
    establish that defendants possess a dangerous level of market power, identification of
    the market is still necessary. See Law v. Nat’l Collegiate Athletic Ass’n, 
    134 F.3d 1010
    , 1020 (10th Cir. 1998) (“[M]arket definition [in antitrust law] . . . is not an end
    unto itself but rather exists to illuminate a practice’s effect on competition.”). If the
    defendants jointly possess monopoly power within that market, it may be that the
    “necessary and direct result” of their conduct was monopolization, even if the
    conduct considered in isolation is not predatory or otherwise competitively
    29
    unreasonable. Griffith, 
    334 U.S. at 106
    . But if the defendants possessed little to no
    power within the relevant market, the nature of their conduct takes on heightened
    importance and must be considered jointly with the defendants’ proposed competitive
    justifications for their actions.
    For example, in American Tobacco the Supreme Court readily determined that
    the defendants (several major American cigarette producers, among others) conspired
    to monopolize commerce, given their dominant control over the national cigarette
    market, and in light of the nature of their conduct, which included horizontal price
    fixing. 
    328 U.S. at
    795–96. By contrast, in a case involving a tying arrangement with
    claims under both § 1 and § 2, the Supreme Court found on the plaintiffs’ § 2
    conspiracy claim that the defendants’ lack of power in the market for the tying
    product (credit) tended to negate their specific intent to monopolize the market for
    the tied product (prefabricated houses). See U.S. Steel Corp., 
    429 U.S. at
    612 & n.1.
    Because the defendants’ market power was lacking, the nature of their conduct (a
    tying arrangement) took on a more prominent role; and the Court determined the
    tying arrangement was lawful because it was used not for monopolistic goals but
    rather for permissible competitive purposes under § 2, such as “increas[ing] sales of
    prefabricated house packages” and “increas[ing] the share of the market.” Id. at 612
    n.1.
    In summary, to prove a conspiracy to monopolize, a plaintiff must show the
    existence of a conspiracy, an overt act in furtherance of the conspiracy, and the
    specific intent to monopolize a relevant market. In this sense, our approach differs
    30
    somewhat from the First Circuit, which “lean[s] toward [requiring proof of a relevant
    market] as a general matter” but does not view “a black or white rule [as] inevitable.”
    Fraser v. Major League Soccer, L.L.C., 
    284 F.3d 47
    , 68 (1st Cir. 2002). In their
    view, “there may in principle be some cases in which one could argue that a
    conspiracy claim should be provable without a showing that the alleged market is a
    real economic market.” 
    Id.
     As explained, we agree that a plaintiff may not need to
    establish a threshold level of market power in some instances, but conclude that
    identification of the relevant market is required for all § 2 conspiracy claims. Such a
    result is compelled by the “any part” language of the statute as explained in Spectrum
    Sports, but it is compelled even more so by the requirement that the conspiracy is
    aimed at monopolization—an inquiry that cannot be conducted in a vacuum. See
    Areeda & Hovenkamp ¶ 802b.
    PART TWO: Regency Has Failed to Identify a Relevant Market
    The district court denied Campus Village’s motion for summary judgment in
    reliance on our holding in Salco that a plaintiff need not identify the relevant market
    to prove a conspiracy-to-monopolize claim. We have now departed from that position
    based on the Supreme Court’s further guidance in Spectrum Sports. Therefore, we
    must consider whether Campus Village’s motion for summary judgment should have
    been granted. Summary judgment is appropriate only if there is no genuine issue of
    material fact and the moving party is entitled to judgment as matter of law. Fed. R.
    Civ. P. 56(a). In considering a denial of summary judgment, “we review the district
    court’s conclusions of law de novo, and construe the record in the light most
    31
    favorable to the party opposing summary judgment.” See Smalley & Co. v. Emerson
    & Cuming, Inc., 
    13 F.3d 366
    , 367 (10th Cir. 1993).
    According to Regency, it has met its burden under § 2 by defining the “part of
    commerce” affected by the defendants’ conduct. We are not persuaded. In providing
    our reasoning for that conclusion, we first explain how the boundaries of a relevant
    market are identified under the antitrust laws and how Regency failed to implement
    those principles here. But because Regency reasonably relied on our prior authority
    that it need not identify the relevant market, we remand the case with guidance to the
    district court to provide Regency a fair opportunity to do so now. In particular, we
    explain the importance of identifying the nature of the alleged anticompetitive
    conduct in considering a plaintiff’s § 2 conspiracy-to-monopolize claim. This in turn
    appropriately focuses the inquiry on the plaintiff’s burden to establish that the
    defendants acted with the specific intent to monopolize, which showing the
    defendants can rebut by introducing evidence of procompetitive justifications for the
    arrangement. Should the conduct prove justifiably competitive, no § 2 conspiracy
    claim will lie.
    A. Regency Failed to Define the Relevant Market
    “Because the relevant market provides the framework against which economic
    power can be measured, defining the product and geographic markets is a threshold
    requirement.” Campfield v. State Farm Mut. Auto. Ins. Co., 
    532 F.3d 1111
    , 1118
    (10th Cir. 2008) (citation omitted) (monopolization and attempt to monopolize). The
    relevant product market in any given case “is composed of products that have
    32
    reasonable interchangeability for the purposes for which they are produced—price,
    use and qualities considered.” SCFC ILC, Inc. v. Visa USA, Inc., 
    36 F.3d 958
    , 966
    (10th Cir. 1994) (quoting United States v. E.I. du Pont de Nemours & Co., 
    351 U.S. 377
    , 404 (1956)). And “[t]he geographic market is the narrowest market which is
    wide enough so that products from adjacent areas cannot compete on substantial
    parity with those included in the market.” Westman Comm’n Co. v. Hobart Int’l, Inc.,
    
    796 F.2d 1216
    , 1222 (10th Cir. 1986) (internal quotation marks omitted). Together
    these factors define a real economic market for purposes of antitrust analysis. See
    Fraser v. Major League Soccer, L.L.C., 
    284 F.3d 47
    , 68 (1st Cir. 2002) (holding that
    although there may be some exceptions, as a general matter a conspiracy-to-
    monopolize claim requires proof of a real economic market).
    In responding to Campus Village’s motion for summary judgment, Regency
    argued that § 2 conspiracy-to-monopolize claims do not require proof of a relevant
    market. The district court agreed and rejected Campus Village’s call to have Regency
    define the relevant market. Instead, Regency was required to define only the
    “segment of commerce” allegedly impacted by Campus Village’s actions, which it
    claims was “the rental of dedicated student housing” for “UCD students attending the
    Auraria campus in downtown Denver.” On appeal, Regency defines the “part of
    commerce” in a slightly different manner, as the business “of private, off-campus
    rental housing in downtown Denver dedicated for Auraria students, particularly UCD
    domestic and international freshmen.”
    33
    But framed in either manner, Regency failed to define a true economic market.
    In particular, Regency’s “market definition is underinclusive. . . . [T]he relevant
    market is one that reflects the total market demand for plaintiffs’ product, not just
    defendants’ demand.” Campfield, 
    532 F.3d at 1118
    . It must take into account
    “competitive substitutes.” 
    Id.
     Instead of focusing on a real economic market, “it is
    clear that [Regency’s] focus is upon a contractually created class of consumers”—
    UCD domestic and international freshmen. See Hack v. President & Fellows of Yale
    Coll., 
    237 F.3d 81
    , 85 (2d Cir. 2000), abrogated on other grounds by Swierkiewicz v.
    Sorema N.A., 
    534 U.S. 506
     (2002). And “[e]conomic power derived from contractual
    arrangements affecting a distinct class of consumers cannot serve as a basis for a
    [conspiracy-to-monopolize] claim.” See 
    id.
     Here, Regency advertises its housing only
    to students at UCD and the nearby educational institutions, so its market is restricted
    by choice, rather than by necessity. And the “part of commerce” it has identified for
    purposes of this litigation fails even to consider other educational institutions in
    Denver, or other segments of the broader Denver rental market. Instead, for all
    practical purposes, Regency asked the district court to examine the effect of Campus
    Village’s conduct on Regency—a single competitor—rather than its impact on
    competition generally.
    By defining the market in such narrow terms, Regency failed to identify a real
    economic market. But its failure to do so may be attributable to its reasonable
    reliance on Salco’s holding that it need not identify the relevant market to pursue a
    conspiracy-to-monopolize claim. Accordingly, we reverse the jury’s verdict but
    34
    remand to provide Regency a fair opportunity to identify the relevant market. See Ill.
    Tool Works Inc. v. Indep. Ink, Inc., 
    547 U.S. 28
    , 46 (2006).
    B. Section 2 Conspiracy Claims Must Be Contextualized
    In remanding the case, we note that an important threshold to cross in any
    antitrust action is the proper classification of the alleged conduct. See, e.g., 
    id. at 46
    (noting that, under § 1, “in all cases involving a tying arrangement, the plaintiff must
    prove that the defendant has market power in the tying product” (emphasis added));
    Novell, Inc. v. Microsoft Corp., 
    731 F.3d 1064
    , 1078 (10th Cir. 2013) (rejecting the
    plaintiff’s attempt “to recast [the defendant’s] conduct as an ‘affirmative’ act of
    interference with a rival rather than a ‘unilateral’ refusal to deal” in an attempt to
    avoid the more rigorous showing under the refusal-to-deal doctrine). That focus is
    necessary because the ultimate inquiry is whether the defendants’ conduct had
    anticompetitive effects in the particular markets affected. While horizontal price
    fixing may easily be deemed pernicious in the target product market, other conduct,
    such as a tying arrangement, may involve closer scrutiny of the tying-product and
    tied-product markets to determine if the conduct is anticompetitive. And although a
    plaintiff may try to obfuscate the true character of the defendants’ conduct in an
    attempt to repackage an unprovable § 1 claim into a § 2 conspiracy claim, it cannot
    avoid the relevant market requirement “by the simple trick of calling the agreement a
    conspiracy to monopolize.” See Phillip E. Areeda & Herbert Hovenkamp, Antitrust
    Law ¶ 809 (4th ed. 2015) (“[O]ne must doubt whether the ‘conspiracy to monopolize’
    language of §2 was ever intended to reach nonhorizontal agreements at all.”); cf.
    35
    Energy Conversion Devices Liquidation Trust v. Trina Solar Ltd., 
    833 F.3d 680
    , 688
    (6th Cir. 2016) (“[Plaintiff] first argues that the label ‘predatory pricing’ and the
    requirement of proof of recoupment attached to it applies only to claims under § 2 of
    the Sherman Act, not § 1. That is word play. The Supreme Court has already used
    ‘predatory pricing’ to describe claims in each setting, whether filed under one section
    or the other.”) Instead, the § 2 claim is dependent upon a close examination of the
    underlying conduct, its proper treatment under the antitrust laws, and its impact on
    the affected market(s).
    The district court considered the nature of the conduct alleged in this case,
    recognizing that proof of a relevant market would be required to establish an
    unlawful tying arrangement under § 1, but it ultimately concluded that § 2 conspiracy
    claims were distinct. And because the court construed Campus Village’s
    characterization of the conduct as a tying arrangement as an affirmative defense, it
    put the onus of defining the relevant market on Campus Village, as a prerequisite of
    proving that defense. This was error, for two interrelated reasons. First, we have now
    departed from Salco based on the Supreme Court’s decision in Spectrum Sports and
    its guidance on the proper interpretation of Yellow Cab and its progeny. With the
    benefit of this advantaged position, it is apparent the district court erred by relieving
    Regency of the obligation to identify the economic market(s) affected by Campus
    Village’s and UCD’s conduct as part of its § 2 conspiracy claim. And as we
    explained above, Regency defined the “part of commerce” impacted by the tied
    product market far too narrowly to constitute a real economic market.
    36
    Second, the issue of whether the conduct here constitutes a tying arrangement
    or some other anticompetitive scheme is not merely an affirmative defense; it informs
    the definition of the relevant market and the inquiry into competitive injury. By
    holding otherwise, the district court never considered the arrangement’s impact on
    the § 2 conspiracy-to-monopolize analysis. Accordingly, we leave this issue for the
    district court to reconsider on remand.
    IV. STATUTE OF LIMITATIONS
    Campus Village also claims the district court erred in ruling that Regency’s
    claims were not barred by the statute of limitations. After the district court heard
    evidence on the issue, Campus Village filed a motion for judgment as a matter of law
    under Rule 50(a) of the Federal Rules of Civil Procedure, which the district court
    denied in an oral ruling, concluding that Campus Village’s and UCD’s enforcement
    actions at the beginning of each school year reset the statute of limitations. The
    district court permitted Regency to recover damages for school years beginning in
    August 2007, but it concluded that Regency was barred from recovering damages for
    the 2006–2007 school year “because the act to enforce the residency requirement at
    the beginning of that school year occurred outside the statute of limitations.” We
    agree with the district court’s analysis. In light of UCD’s ongoing enforcement
    actions, the continuing conspiracy exception served to revive Regency’s claims that
    would otherwise be time-barred.
    37
    “We review de novo a district court’s decision to grant or deny a Rule 50(a)
    motion for judgment as a matter of law, applying the same standards as the district
    court.” Elm Ridge Expl. Co. v. Engle, 
    721 F.3d 1199
    , 1216 (10th Cir. 2013).
    “Judgment as a matter of law is appropriate only if the evidence points but one way
    and is susceptible to no reasonable inferences which may support the nonmoving
    party’s position.” 
    Id.
     (internal quotation marks omitted). This standard mirrors the
    summary judgment standard in that “the trial judge must direct a verdict if, under the
    governing law, there can be but one reasonable conclusion as to the verdict.”
    Anderson v. Liberty Lobby, Inc., 
    477 U.S. 242
    , 250 (1986).
    Under 15 U.S.C. § 15b, a claim under § 2 of the Sherman Act “shall be forever
    barred unless commenced within four years after the cause of action accrued.” “The
    general rule is that an antitrust ‘cause of action accrues and the statute begins to run
    when a defendant commits an act that injures a plaintiff’s business.’” Kaw Valley
    Elec. Coop. Co. v. Kansas Elec. Power Coop., Inc., 
    872 F.2d 931
    , 933 (10th Cir.
    1989) (quoting Zenith Radio Corp. v. Hazeltine Research, Inc., 
    401 U.S. 321
    , 338
    (1971)). Stated otherwise, a cause of action accrues on the “particular date” that “a
    plaintiff feels the adverse impact of an antitrust conspiracy.” Zenith Radio Corp., 
    401 U.S. at 339
    . Here, the cause of action appears to have accrued in November 2005,
    when the residency requirement was promulgated and students for the upcoming
    school year were officially precluded from living at the Regency. For its part,
    Regency was clearly aware of the requirement by April 2006 when its attorneys sent
    a letter to Campus Village inquiring about the import of the residency requirement on
    38
    students. But at the very latest, Regency’s claims initially accrued in August 2006, as
    Campus Village contends, when the 2006–2007 school year began and the first set of
    students began living at Campus Village.
    Because Regency did not file suit until over four years later—October 2010—
    its claims are barred absent tolling or some other exception to the statute of
    limitations. Regency does not dispute that it first learned of the residency
    requirement outside of the statute of limitations, but it claims the “continuing
    conspiracy” exception to § 15b applies, which provides:
    In the context of a continuing conspiracy to violate the antitrust laws,
    each time a plaintiff is injured by an act of the defendants a cause of
    action accrues to him to recover the damages caused by that act and as
    to those damages, the statute of limitations runs from the commission of
    the act. The exception thus has two requirements that are not entirely
    consistent: [1] the acts in question must be distinct from the acts outside
    the limitations period, but [2] they must continue the same conspiracy.
    Champagne Metals v. Ken-Mac Metals, Inc., 
    458 F.3d 1073
    , 1088 (10th Cir. 2006)
    (alterations and internal quotation marks omitted). Stated otherwise, an overt act will
    restart the statute of limitations under the continuing conspiracy exception when the
    act is (1) “a new and independent act that is not merely a reaffirmation of a previous
    act”; and (2) the act “inflict[s] new and accumulating injury on the plaintiff.” Kaw
    Valley, 
    872 F.2d at 933
     (internal quotation marks omitted). The act must be more
    than “the abatable but unabated inertial consequences of some pre-limitations
    action.” 
    Id.
     (internal quotation marks omitted).
    “Whether an antitrust violation should be characterized as a single act or
    continuing violation is best determined by considering the type of violation
    39
    involved.” 8 Julian O. von Kalinowski et al., Antitrust Laws and Trade Regulation,
    § 162.02[2] (2d ed. 2016). Here, both parties adopt the “refusal to deal” framework,
    even though the conduct at issue does not fit neatly within that construct.
    Notwithstanding, the principles enunciated in both Champagne Metals and Kaw
    Valley inform our analysis. In Champagne Metals, this court addressed the
    continuing conspiracy exception as applied to a horizontal group boycott. 
    458 F.3d at 1078
    . In that context, we readily determined that the defendants’ initial conspiracy to
    exclude a competitor was not “final,” since the alleged boycott required ongoing
    enforcement efforts, which inflicted “new and accumulating injury” on the
    competitor. 
    Id.
     at 1089–90 (internal quotation marks omitted). Accordingly, we ruled
    that the continuing conspiracy exception applied.
    By contrast, in Kaw Valley, we ruled that the exception did not apply. 
    872 F.2d at
    934–35. In that case, an electrical cooperative issued a pronouncement clearly
    barring non-member cooperatives from accessing power. That refusal, unlike the
    exclusionary conduct in Champagne Metals, was decreed by a single entity, required
    no ongoing enforcement efforts, and subsequent refusals did not inflict accumulating
    injury. The refusal “sent a clear message” to the non-member cooperative that “it
    would have to join up or litigate.” 
    Id. at 935
    . The finality of the decree was clear, the
    injury was immediate and circumscribed, and we therefore concluded that the
    continuing conspiracy exception did not apply. 
    Id.
    Here, the allegation is that UCD and Campus Village conspired to exclude
    Regency from the UCD freshmen student housing market. Their initial conspiratorial
    40
    decision—the promulgation of the residency requirement—was not “final” in the
    nature of Kaw Valley, as UCD’s efforts to enforce the requirement each year make
    clear. Moreover, the injury to Regency was “new and accumulating” in two senses:
    first, a new group of students was excluded each year as a result of the requirement;
    second, UCD and Campus Village broadened the requirement in later years to
    encompass a larger group of students. As a result, the district court correctly
    determined that the continuing conspiracy exception applied.
    V. STATE ACTION IMMUNITY
    As a final matter, Campus Village argues Regency’s claims are barred by
    state-action immunity. The application of the state-action immunity doctrine presents
    a question of law, which we review de novo. Trigen Okla. City Energy Corp. v. Okla.
    Gas & Elec. Co., 
    244 F.3d 1220
    , 1225 (10th Cir. 2001). As a general principle, “state
    action immunity is disfavored.” N.C. State Bd. of Dental Exam’rs v. FTC, 
    135 S. Ct. 1101
    , 1110 (2015) (internal quotation marks omitted).
    Early in the litigation, Campus Village raised the defense of state action
    immunity in a motion to dismiss, which the district court denied. Campus Village
    then filed an interlocutory appeal from the district court’s order, and Regency filed a
    motion to dismiss the appeal, claiming this court lacked jurisdiction. Campus Village
    I, 
    703 F.3d 1147
     (10th Cir. 2013). We refused to broaden the collateral order doctrine
    to permit Campus Village (a private entity) to appeal from the non-final order, and
    granted Regency’s motion to dismiss the appeal. 
    Id. at 1153
    . Now that the district
    41
    court’s orders are properly before us, Campus Village again appeals the district
    court’s ruling denying its motion to dismiss on state action immunity grounds. We
    hold that the state action immunity doctrine does not preclude Regency’s claims, and
    we therefore affirm the district court’s order.
    “The state action immunity doctrine . . . exempts qualifying state and local
    government regulation from federal antitrust, even if the regulation at issue compels
    an otherwise clear violation of the federal antitrust laws.” Zimomra v. Alamo Rent-A-
    Car, Inc., 
    111 F.3d 1495
    , 1498 (10th Cir. 1997) (citation and internal quotation
    marks omitted). “Although the doctrine was [originally] aimed at protecting state
    legislatures and state supreme courts acting in their legislative capacities, it can
    provide protection to other individuals or entities acting pursuant to state
    authorization.” 
    Id.
     This includes private parties. Campus Village I, 703 F.3d at 1149.
    But “[i]n such situations, . . . closer analysis is required to determine whether
    antitrust immunity is appropriate.” Zimomra, 
    111 F.3d at 1498
     (internal quotation
    marks omitted).
    The Supreme Court’s Midcal decision sets forth the governing test for when
    state action immunity will be extended to non-state actors—(1) “the challenged
    restraint must be one clearly articulated and affirmatively expressed as state policy,”
    and (2) “the policy must be actively supervised by the State itself.” Cal. Retail
    Liquor Dealers Ass’n v. Midcal Aluminum, Inc., 
    445 U.S. 97
    , 105 (1980) (internal
    quotation marks omitted). Where a private party seeks to invoke the immunity, the
    threshold question is whether that party must satisfy both requirements, or whether it
    42
    need satisfy only the first requirement, as is the case for municipalities. See Town of
    Hallie v. City of Eau Claire, 
    471 U.S. 34
    , 46–47 (1985) (“Town of Hallie test”). In
    Zimomra, this court applied the Town of Hallie test to private rental car companies
    because those companies had no discretion on whether to engage in the allegedly
    anticompetitive conduct (the imposition and collection of a daily airport usage fee as
    required by a county ordinance). 
    111 F.3d at
    1498–1501.
    Here, Campus Village argues that, in light of UCD’s clear involvement in
    promulgating the residency requirement, no showing of “active supervision” is
    required. Regency’s tactical decision to exclude UCD as a party to the litigation does
    not mean the other alleged conspirator—Campus Village—must therefore satisfy the
    second prong of Midcal. And regardless, UCD—a constitutionally created state
    institution—has actively supervised both the residency requirement (which it
    promulgated) and the other steps of its arrangement with Campus Village. Regency
    claims instead that Campus Village (a private entity) was the sole actor involved in
    “setting rental rates” such that the active supervision requirement is not met. But the
    allegedly anticompetitive arrangement relied on by Regency was not the setting of
    rental rates—it was the residency requirement itself.
    The district court in this case applied the Town of Hallie test and concluded
    that Campus Village was not required to show that the residency requirement was
    actively supervised by the State itself. We need not consider whether this was correct
    because even if Campus Village is excused from meeting the second prong of the
    Midcal test, it cannot meet its burden of establishing that the residency requirement
    43
    was “clearly articulated and affirmatively expressed as state policy.” Midcal, 
    445 U.S. at 105
    .
    Whether a state policy is clearly and affirmatively expressed such that
    immunity extends to private parties is a matter of degree. 
    Id.
     In Kay Electric
    Cooperative v. City of Newkirk, this court stated that, at minimum, a municipal
    defendant seeking state action immunity “bear[s] the burden of showing that its
    challenged conduct was at least a foreseeable (if not explicit) result of state
    legislation.” 
    647 F.3d 1039
    , 1043 (10th Cir. 2011). Acknowledging that “what does
    and doesn’t qualify as foreseeable is hardly ‘self-evident,’” 
    id.,
     we identified a few
    bright line rules to be used to inform the analysis. First, we determined that standard
    charters authorizing municipalities to enter contracts, buy and sell property, or form
    joint ventures, do not make a municipality’s anticompetitive conduct foreseeable. 
    Id.
    We reasoned that such power is available generally to both individuals and artificial
    entities, but gives them no right to engage in anticompetitive activity. 
    Id.
     The second
    bright line rule this court set forth was, “the fact that a state may have authorized
    some forms of municipal anticompetitive conduct isn’t enough to make all forms of
    anticompetitive conduct foreseeable.” 
    Id.
     at 1043–44. Third, we noted that any
    immunity granted must be defined by “the most specific direction issued by the state
    legislature on the subject.” 
    Id. at 1044
    . Indeed, the United States Supreme Court later
    noted that the concept of foreseeability here cannot be applied “too loosely.” FTC v.
    Phoebe Putney Health Sys., Inc., 
    133 S. Ct. 1003
    , 1012 (2013). Stated in a different
    light—and as recognized by the district court—“there must be a clearly articulated
    44
    and affirmatively expressed state policy to displace competition.” Allright Colo., Inc.
    v. City & Cty. of Denver, 
    937 F.2d 1502
    , 1507 (10th Cir. 1991) (emphasis added)
    (internal quotation marks omitted). To answer whether such policy exists in this case,
    we must turn to the governing Colorado statutes, housed in the Colorado Educational
    and Cultural Facilities Authority Act (the Act).
    That Act does not provide the requisite “clearly articulated and affirmatively
    expressed state policy.” 
    Id.
     To be sure, the Act empowers the Colorado Educational
    and Cultural Facilities Authority (CECFA or the Authority) to construct, acquire, and
    otherwise maintain “housing facilit[ies]” and “recreational facilit[ies].” 
    Colo. Rev. Stat. § 23-15-103
    (8.5)(a)(I)(A). It is also true that the Act empowers the Authority to
    issue bonds and require “any agreements and provisions” related to “the fixing and
    collection of mortgage payments, rents, fees, and other charges” as part of its
    contracts with bondholders related to the financing of housing and other facilities. 
    Id.
    § 23-15-112(1)(c). Such agreements may be entered into in order to ensure “the
    security of the holders of such bonds or notes.” Id. § 23-15-112(1)(l). But neither of
    these provisions—nor any other provision cited by Campus Village—clearly
    articulates a state policy “to displace competition.” Allright Colo., 
    937 F.2d at 1507
    .
    As with the powers conferred to municipalities by charter in Kay Electric, every
    issuer of bonds has the authority to require sufficient collateral or security to protect
    the holders’ underlying investment. The fact that the Act here similarly grants the
    Authority permission to enter into agreements to ensure “the security of the holders
    of such bonds or notes” does not mean the legislature blessed anti-competitive
    45
    behavior in the marketplace. 
    Colo. Rev. Stat. § 23-15-112
    (1)(l). At bottom, these
    provisions collectively do nothing more than grant CECFA and other institutions
    powers that are common in the marketplace. And there is nothing in the statutes that
    makes anticompetitive activity foreseeable. See Kay Elec., 
    647 F.3d at 1043
    (“[S]imple permission to play in a market doesn’t foreseeably entail permission to
    roughhouse in that market unlawfully.”). Accordingly, the district court properly
    determined that state action immunity did not apply.
    VI. CONCLUSION
    To prove a conspiracy to monopolize under § 2 of the Sherman Act, the
    plaintiff must identify the relevant market. Regency failed to do so in this case. But
    because Regency reasonably relied on our contrary holding in Salco, we instruct the
    district court to provide Regency an opportunity to define the relevant market on
    remand. Accordingly, we VACATE the jury verdict and REMAND for proceedings
    consistent with this decision. Having disposed of this appeal, we also DISMISS as
    moot Regency’s motion to strike ¶3 of Campus Village’s supplemental authority.
