    the laws before they took effect. The panel held that the
    plaintiffs failed to establish parens patriae standing because:
    (1) they failed to articulate an interest apart from the interests
    of private egg producers, who could have filed an action on
    their own behalf; (2) the allegations about potential economic
    effects of the challenged laws, after implementation, were
    necessarily speculative; and (3) the allegations of
    discrimination were misplaced because the laws do not
    distinguish among eggs based on their state of origin. The
    panel further held that the district court did not err by denying
    leave to amend because plaintiffs would be unable to assert
    parens patriae standing in an amended complaint.
    The panel held that because in theory, plaintiffs could
    allege post-effective-date facts that might support standing,
    the complaint should have been dismissed without prejudice.

    ORDER
    The opinion filed November 17, 2016, and published at
    
    842 F.3d 658
    , is amended by the opinion filed concurrently
    with this order. No further petitions for rehearing or
    rehearing en banc may be filed.
    OPINION
    GRABER, Circuit Judge:
    California enacted laws and regulations prescribing
    standards for the conditions under which chickens must be
    kept in order for their eggs to be sold in the state. Plaintiffs
    are six states, which sued to block enforcement of those laws
    and regulations before they took effect. We agree with the
    district court that Plaintiffs lacked standing to bring this case
    as parens patriae. We also hold that the district court did not
    err in denying Plaintiffs leave to amend their complaint. But
    because the action should have been dismissed without
    prejudice, we affirm but remand with instructions to dismiss
    the action without prejudice.
    In the 2008 general election, California voters adopted
    Proposition 2, which enacted new standards beginning on
    January 1, 2015, for housing farm animals within California
    including, as relevant here, egg-laying hens. 
    Cal. Health & Safety Code §§ 25990
    –94. Under Proposition 2, hens may
    not be confined for the majority of any day “in a manner that
    prevents [them] from: (a) Lying down, standing up, and fully
    extending [their] limbs; and (b) Turning around freely.” 
    Id.
    § 25990. A violation of these standards is punishable by a
    6     STATE OF MISSOURI EX REL.KOSTER V. HARRIS
    $1,000 fine or imprisonment of 180 days in county jail, or
    both. Id. § 25993.
    In 2010, California’s legislature adopted Assembly Bill
    1437 (“AB1437”), which mandated, also beginning on
    January 1, 2015, that “a shelled egg shall not be sold or
    contracted for sale for human consumption in California if the
    seller knows or should have known that the egg is the product
    of an egg-laying hen that was confined on a farm or place that
    is not in compliance with animal care standards set forth in
    [Proposition 2].” 
    Cal. Health & Safety Code § 25996
    .
    Therefore, all eggs sold in California must comply with
    Proposition 2. In 2013, the California Department of Food
    and Agriculture promulgated egg-related regulations,
    including salmonella prevention measures and minimum cage
    sizes for egg-laying hens, all of which also carried an
    effective date of January 1, 2015. 
    Cal. Code Regs. tit. 3, § 1350
    (d)(1).
    On February 3, 2014, the State of Missouri filed a
    complaint in the Eastern District of California, asking the
    court to declare AB1437 and California Code § 1350(d)(1)
    (collectively the “Shell Egg Laws”) invalid, as violating the
    Commerce Clause or as preempted by federal statute, and to
    enjoin California from enforcing the laws. Plaintiffs then
    filed their First Amended Complaint (the “complaint”),
    joining the States of Nebraska, Oklahoma, Alabama, and
    Kentucky and the Governor of Iowa as additional plaintiffs.
    The Humane Society of the United States and the Association
    of California Egg Farmers (“Intervenors”) moved to intervene
    as defendants, which the court allowed. Defendants filed a
    motion to dismiss for lack of subject matter jurisdiction;
    Intervenors filed their own, similar motions. The district
    court granted the motions to dismiss, with prejudice. The
    court concluded that Plaintiffs lacked standing as parens
    STATE OF MISSOURI EX REL.KOSTER V. HARRIS               7
    patriae, held that their claim was not justiciable, and denied
    leave to amend as futile. Plaintiffs timely appeal.
    A. Parens Patriae Standing
    States asserting parens patriae standing must meet both
    the basic requirements of Article III standing and the unique
    requirements of that doctrine. Table Bluff Reservation (Wiyot
    Tribe) v. Philip Morris, Inc., 
    256 F.3d 879
    , 885 (9th Cir.
    2001). “To establish Article III standing, an injury must be
    concrete, particularized, and actual or imminent; fairly
    traceable to the challenged action; and redressable by a
    favorable ruling.” Clapper v. Amnesty Int’l USA, 
    133 S. Ct. 1138
    , 1147 (2013) (internal quotation marks omitted). In a
    parens patriae case, there are two additional requirements.
    First, “the State must articulate an interest apart from the
    interests of particular private parties, i.e., the State must be
    more than a nominal party.” Alfred L. Snapp & Son, Inc. v.
    Puerto Rico ex rel. Barez (“Snapp”), 
    458 U.S. 592
    , 607
    (1982). Second, “[t]he State must express a quasi-sovereign
    interest.” 
    Id.
     On de novo review, Habeas Corpus Res. Ctr.
    v. U.S. Dep’t of Justice, 
    816 F.3d 1241
    , 1247 (9th Cir. 2016),
    we conclude that Plaintiffs have not met the first requirement.
    We therefore need not, and do not, reach the second part of
    the test, nor do we reach the issue of ripeness.
    There are no “definitive limits on the proportion of the
    population of the State that must be adversely affected.”
    Snapp, 
    458 U.S. at 607
    . But “more must be alleged than
    injury to an identifiable group of individual residents.” 
    Id.
    “[T]he indirect effects of the injury must be considered as
    8       STATE OF MISSOURI EX REL.KOSTER V. HARRIS
    well in determining whether the State has alleged injury to a
    sufficiently substantial segment of its population.” Id.1
    Concerning the parties, the complaint alleges: “Missouri
    farmers produced nearly two billion eggs in 2012 and
    generated approximately $171 million in revenue for the
    state”; “Nebraska is one of the top ten largest egg producers
    in the United States”; “Alabama is one of the top fifteen
    largest egg producers in the United States”; “Kentucky
    farmers produced approximately 1.037 billion eggs in 2012
    and generated approximately $116 million in revenue for the
    state”; “Oklahoma farmers produced more than 700 million
    eggs in 2012 and generated approximately $90 million in
    revenue for the state”; and “Iowa is the number one state in
    egg production[,] Iowa farmers produce over 14.4 billion
    eggs per year,” and “[t]he cost to Iowa farmers to retrofit
    existing housing or build new housing that complies with
    AB1437 would be substantial.”
    The laws “forc[e] Plaintiffs’ farmers either to forgo
    California’s markets altogether or accept significantly
    increased production costs just to comply.” That is,
    “Plaintiffs’ egg farmers must choose either to bring their
    entire operations into compliance . . . or else simply leave the
    1
    It is unclear whether “substantial segment of the population” and
    “interest apart from the interest of particular private parties” are separate
    elements of standing. See, e.g., Washington v. Chimei Innolux Corp.,
    
    659 F.3d 842
    , 847 (9th Cir. 2011) (describing these as separate
    requirements). Snapp itself suggests that “substantial segment” may be
    merely an additional explanation of the need for the State to be “more than
    a nominal party.” 
    458 U.S. at 607
    . The district court likewise combined
    these concepts into one element. Given the close similarity of the parties’
    arguments under these headings, we discuss the two formulations as a
    single element, but we would reach the same conclusion even if we treated
    them separately.
    STATE OF MISSOURI EX REL.KOSTER V. HARRIS                     9
    California marketplace.”       “[T]he necessary capital
    improvements [would] cost Plaintiffs’ farmers hundreds of
    millions of dollars,” and, without access to the California
    market, “supply would outpace demand by half a billion eggs,
    causing the price of eggs—as well as egg farmers’
    margins—to fall throughout the Midwest and potentially
    forc[e] some Missouri producers out of business. The same
    goes for egg producers in Nebraska, Alabama, Oklahoma,
    Kentucky, and Iowa.”
    In short, the complaint alleges the importance of the
    California market to egg farmers in the Plaintiff States and
    the difficult choice that egg farmers face in deciding whether
    to comply with the Shell Egg Laws. The complaint contains
    no specific allegations about the statewide magnitude of these
    difficulties2 or the extent to which they affect more than just
    an “identifiable group of individual” egg farmers. Snapp,
    
    458 U.S. at 607
    .
    Plaintiffs advance several theories to demonstrate “an
    interest apart from the interests of particular private parties”
    and an effect on “a sufficiently substantial segment of [the]
    population.” 
    Id.
     First, Plaintiffs allege harm to their egg
    farmers. Second, Plaintiffs argue that the Shell Egg Laws
    will cause harmful fluctuations in the price of eggs. Finally,
    Plaintiffs allege that they will suffer discrimination from the
    Shell Egg Laws. For the reasons that follow, none of these
    theories establishes standing.
    2
    At a hearing, the district court asked Plaintiffs where in their
    complaint they alleged harm to more than just egg producers. Plaintiffs’
    lawyer pointed to paragraphs 7 and 13. Paragraph 7 describes harm to egg
    farmers. Paragraph 13 includes no specific facts, stating only, in
    conclusory fashion, that “Missouri’s economy and status within the
    federal system will be irreparably injured.”
    10     STATE OF MISSOURI EX REL.KOSTER V. HARRIS
    1. Alleged Harm to Egg Farmers
    Alleging harm to the egg farmers in Plaintiffs’ States is
    insufficient to satisfy the first prong of parens patriae
    standing. Other courts have recognized that parens patriae
    standing is inappropriate where an aggrieved party could seek
    private relief. The Second Circuit, for example, held that
    “[p]arens patriae standing . . . requires a finding that
    individuals could not obtain complete relief through a private
    suit.” N.Y. ex rel. Abrams v. 11 Cornwell Co., 
    695 F.2d 34
    ,
    40 (2d Cir. 1982), vacated in part on other grounds, 
    718 F.2d 22
     (2d Cir. 1983) (en banc); see also Connecticut v.
    Physicians Health Servs. of Conn., Inc., 
    103 F. Supp. 2d 495
    ,
    504 (D. Conn. 2000) (noting that “the Second Circuit has
    interpreted Snapp to require a finding that the State act on
    behalf of individuals who could not obtain complete relief
    through a private suit”). Here, complete relief would be
    available to the egg farmers themselves, were they to file a
    complaint on their own behalf.
    Supreme Court cases in which private relief was held to
    be unlikely or unrealistic illustrate why parens patriae
    standing does not lie here. In Missouri v. Illinois, 
    180 U.S. 208
     (1901), though never explicitly calling it a parens patriae
    case, the Supreme Court heard a sewage dispute between two
    states. The Court observed that “the nature of the injury
    complained of is such that an adequate remedy can only be
    found in this court at the suit of the state of Missouri.” Id. at
    241. The Court emphasized that the “health and comfort of
    the large communities inhabiting those parts of the state
    situated on the Mississippi River are not alone concerned, but
    contagious and typhoidal diseases introduced in the river
    communities may spread themselves throughout the territory
    of the state.” Id.; see also Snapp, 
    458 U.S. at 603
     (describing
    “a line of cases . . . in which States successfully sought to
    STATE OF MISSOURI EX REL.KOSTER V. HARRIS               11
    represent the interests of their citizens in enjoining public
    nuisances”). In other words, Missouri alleged that a public
    health hazard affected its entire population. By contrast, the
    Shell Egg Laws are not alleged to threaten the health of the
    entire population (or, indeed of anyone), and those directly
    affected—egg farmers—are capable of pursuing their own
    interests.
    A rationale similar to that in Missouri v. Illinois supported
    parens patriae standing in Maryland v. Louisiana, 
    451 U.S. 725
     (1981). There, Louisiana imposed a “First-Use Tax” on
    natural gas piped into the state from federal offshore drilling
    areas. A group of states, later joined by the federal
    government and several pipeline companies, filed an original
    jurisdiction suit in the Supreme Court challenging the tax
    under, among other sources, the Commerce Clause. The
    Court found jurisdiction on several theories, including the
    States’ interest as parens patriae. 
    Id. at 737
    . The Court
    observed that
    the incidence of the Tax [does not] fall on a
    small group of citizens who are likely to
    challenge the Tax directly. Rather, a great
    many citizens in each of the plaintiff States
    are themselves consumers of natural gas and
    are faced with increased costs aggregating
    millions of dollars per year. As the Special
    Master observed, individual consumers cannot
    be expected to litigate the validity of the First-
    Use Tax given that the amounts paid by each
    consumer are likely to be relatively small.
    
    Id. at 739
    . Maryland v. Louisiana’s logic counsels the
    opposite result here: Whereas millions of consumers
    probably cannot challenge another state’s tax on their
    12     STATE OF MISSOURI EX REL.KOSTER V. HARRIS
    commodities, large egg producers certainly could file an
    action like this one on their own.
    2. Alleged Fluctuation in the Price of Eggs
    Plaintiffs argue that fluctuations in the price of eggs will
    harm consumers, thereby affecting a substantial segment of
    their populations and establishing parens patriae standing.
    Plaintiffs filed their complaint before the Shell Egg Laws
    took effect. As a result, their allegations about the potential
    economic effects of those laws, after implementation, were
    necessarily speculative. Indeed, Plaintiffs’ allegations are
    inconsistent; the complaint alleges that prices will go either
    up or down. On the one hand, Plaintiffs allege that farmers
    must bring all egg facilities into compliance with the Shell
    Egg Laws, regardless of the proportion of their product
    actually bound for California, because the demand across
    markets fluctuates. The cost of “compliant” eggs will thus
    increase across the board. On the other hand, Plaintiffs allege
    that, if farmers decline to comply and they exit the California
    market, “the price of eggs . . . [would] fall throughout the
    Midwest.” Neither of these alleged results is sufficient to
    support parens patriae standing.
    At the outset, the unavoidable uncertainty of the alleged
    future changes in price makes the alleged injury insufficient
    for Article III standing. In Lujan v. Defenders of Wildlife,
    
    504 U.S. 555
    , 562 (1992), the Supreme Court explained that
    it is “substantially more difficult” for a plaintiff to establish
    standing when the plaintiff “is not himself the object of the
    government action or inaction he challenges”:
    [C]ausation and redressability ordinarily
    hinge on the response of the regulated (or
    regulable) third party to the government
    STATE OF MISSOURI EX REL.KOSTER V. HARRIS             13
    action or inaction—and perhaps on the
    response of others as well. The existence of
    one or more of the essential elements of
    standing depends on the unfettered choices
    made by independent actors not before the
    courts and whose exercise of broad and
    legitimate discretion the courts cannot
    presume either to control or to predict, and it
    becomes the burden of the plaintiff to adduce
    facts showing that those choices have been or
    will be made in such manner as to produce
    causation and permit redressability of injury.
    
    Id.
     (citations and internal quotation marks omitted).
    Although Lujan describes facts that must be averred on
    summary judgment, the complaint here cannot allege, even
    under the more permissive standards at the pleading stage,
    that the choices leading to consumer price increases “have
    been or will be made.” 
    Id.
     Instead, the allegations in the
    complaint are “too speculative for Article III purposes,” and
    Plaintiffs have failed to explain how the injury is “certainly
    impending.” 
    Id.
     at 565 n.2 (quoting Whitmore v. Arkansas,
    
    495 U.S. 149
    , 158 (1990)); see also Clapper, 
    133 S. Ct. at 1147
     (rejecting the Second Circuit’s “objectively reasonable
    likelihood” standard as “inconsistent with our requirement
    that threatened injury must be certainly impending to
    constitute injury in fact” (internal quotation marks omitted));
    Ass’n of Pub. Agency Customers v. Bonneville Power Admin.,
    
    733 F.3d 939
    , 952 (9th Cir. 2013) (finding concrete,
    particularized injury when utility price increases will affect
    customer-plaintiffs indirectly due to “‘pass-through’
    contracts” that “almost certainly” pass along increases).
    Unlike the First-Use Tax in Maryland v. Louisiana or the
    threatened withdrawal of West Virginia gas in Pennsylvania
    v. West Virginia, 
    262 U.S. 553
     (1923)—both of which
    14    STATE OF MISSOURI EX REL.KOSTER V. HARRIS
    presented state actions with nearly certain price effects for
    many or all of the plaintiffs’ citizens—here, the alleged price
    effects for consumers are remote, speculative, and contingent
    upon the decisions of many independent actors in the causal
    chain in response to California laws that have no direct effect
    on either price or supply. The Supreme Court has been
    “reluctant to endorse standing theories that require guesswork
    as to how independent decisionmakers will exercise their
    judgment.” Clapper, 
    133 S. Ct. at 1150
    .
    In one of the proposed scenarios Plaintiffs suggest could
    occur, the egg farmers in Plaintiffs’ states do not bring their
    farms into compliance with the Shell Egg Laws. If Plaintiffs’
    allegation correctly predicts that egg prices in the Midwest
    would drop due to excess supply, no ill effects for egg
    consumers would come to pass. Indeed, such a change would
    benefit Plaintiffs’ consumers. It would be only egg farmers,
    not consumers, who might suffer an injury in that scenario.
    But, as we have explained, an injury to egg farmers alone is
    not sufficient to sustain parens patriae standing. In short,
    Plaintiffs’ price-related allegations do not support Article III
    standing.
    The result in Maryland v. Louisiana is not to the contrary.
    There, explaining that a state “may act as the representative
    of its citizens in original actions where the injury alleged
    affects the general population of a State in a substantial way,”
    
    451 U.S. at 737
     (emphasis added), the Court found that the
    plaintiff states had alleged injury both to their proprietary
    interests as gas consumers and to their citizens “from
    substantial economic injury presented by imposition of the
    First-Use Tax,” 
    id. at 739
     (emphasis added). Plaintiffs do not
    allege a similarly substantial injury here. Natural gas is a
    commodity so universally critical to state governments,
    businesses, and ordinary consumers that the Supreme Court
    STATE OF MISSOURI EX REL.KOSTER V. HARRIS               15
    has twice granted parens patriae standing to challenge state
    actions that directly threaten shortages or price increases. Id.;
    Pennsylvania, 262 U.S. at 592 (describing a cut-off in gas as
    “a matter of grave public concern”). An ordinary consumer
    commodity, such as eggs, lacks the central economic
    significance to a state of a utility’s product, such as natural
    gas.
    3. Alleged Discrimination
    Finally, Plaintiffs’ reliance on cases granting parens
    patriae standing to challenge discrimination against a state’s
    citizens is misplaced. The Shell Egg Laws do not distinguish
    among eggs based on their state of origin. A statute that
    treats “both intrastate and interstate products” alike “is not
    discriminatory.” Ass’n des Eleveurs de Canards et d’Oies du
    Quebec v. Harris, 
    729 F.3d 937
    , 948 (9th Cir. 2013).
    In Snapp, Puerto Rico, acting as parens patriae, sued on
    behalf of its workers who allegedly suffered discrimination
    under a federal hiring program. The Court rejected “too
    narrow a view of the interests at stake.” Snapp, 
    458 U.S. at 609
    . Although only 787 jobs were at issue, the nature of the
    discrimination affected all Puerto Ricans, so Puerto Rico
    could pursue relief for all residents under a parens patriae
    theory. 
    Id.
     But Snapp does not assist Plaintiffs because there
    is no discrimination here, whether to the few or to the many.
    As noted, California egg farmers are subject to the same rules
    as egg farmers from all other states, including California
    itself.
    Georgia v. Pennsylvania R. Co., 
    324 U.S. 439
     (1945), is
    no more helpful to Plaintiffs than is Snapp. There, Georgia
    sued a collection of southern railroads, alleging
    discriminatory price-fixing to the detriment of the entire
    16       STATE OF MISSOURI EX REL.KOSTER V. HARRIS
    economy of Georgia. The Court held that the State was not
    a mere nominal plaintiff, with “individual shippers being the
    real complainants.” 
    Id. at 452
    . Instead, the implications of
    price discrimination against Georgia-based commerce were
    “matters of grave public concern in which Georgia ha[d] an
    interest apart from that of particular individuals who may be
    affected,” 
    id. at 451
    , because rail rates “may arrest the
    development of a State or put it at a decided disadvantage in
    competitive markets,” 
    id. at 450
    . By contrast, Plaintiffs
    allege no trade barriers erected against their broader
    economies and, again, the Shell Egg Laws are not
    discriminatory. Accordingly, Plaintiffs’ allegations of
    discrimination do not establish parens patriae standing.
    B. Leave to Amend
    Plaintiffs urge us to reverse the district court’s denial of
    leave to amend their complaint. They seek “[a]t the very least
    . . . to plead the additional information [that they have]
    gathered since the Shell Egg Laws went into effect.”3
    “Denial of leave to amend is reviewed for an abuse of
    discretion.” Dougherty v. City of Covina, 
    654 F.3d 892
    , 897
    (9th Cir. 2011). “Dismissal without leave to amend is
    improper unless it is clear, upon de novo review, that the
    complaint could not be saved by any amendment.” Thinket
    Ink Info Res., Inc. v. Sun Microsystems, Inc., 
    368 F.3d 1053
    ,
    1061 (9th Cir. 2004). But a “district court does not err in
    denying leave to amend where the amendment would be
    futile.” 
    Id.
     (internal quotation marks omitted). An
    amendment is futile when “no set of facts can be proved
    under the amendment to the pleadings that would constitute
    3
    As construed by the district court and as argued on appeal, Plaintiffs
    seek to amend their complaint. They do not seek to supplement the
    pleadings pursuant to Federal Rule of Civil Procedure 15(d).
    STATE OF MISSOURI EX REL.KOSTER V. HARRIS              17
    a valid and sufficient claim or defense.” Miller v. Rykoff-
    Sexton, Inc., 
    845 F.2d 209
    , 214 (9th Cir. 1988). We find no
    abuse of discretion.
    First, Plaintiffs cannot satisfy the requirements of
    standing by adding events that have occurred after the Shell
    Egg Laws took effect. “[S]tanding is determined as of the
    commencement of litigation.” Yamada v. Snipes, 
    786 F.3d 1182
    , 1203 (9th Cir.), cert. denied, 
    136 S. Ct. 569
     (2015)
    (internal quotation marks omitted); accord D’Lil v. Best W.
    Encina Lodge & Suites, 
    538 F.3d 1031
    , 1036 (9th Cir. 2008).
    Plaintiffs brought this action before the Shell Egg laws took
    effect. Accordingly, later developments cannot save the
    complaint.
    Second, Plaintiffs argue that certain allegations were
    available when the complaint was filed and that they should
    be allowed to include them now. In particular, Plaintiffs wish
    to allege that eggs are an important, affordable source of
    protein with which the Shell Egg Laws threaten to interfere,
    and that the threat of increased egg prices affects not just egg
    farmers, but also “grocers, bakers, and restaurant owners.”
    But Plaintiffs also allege that the price of eggs might drop.
    Again, as discussed above, the contingent and uncertain
    nature of the alternatives available to plead when this
    complaint was filed are inadequate to support Article III
    standing.
    In short, Plaintiffs would be unable to assert parens
    patriae standing in an amended complaint. The district court
    did not err by denying leave to amend.

    C. Dismissal With Prejudice
    Finally, Plaintiffs argue that, because the district court
    dismissed the complaint for lack of subject matter
    jurisdiction, the dismissal should have been without
    prejudice. “We review for abuse of discretion a district
    court’s decision to dismiss with prejudice.” Okwu v. McKim,
    
    682 F.3d 841
    , 844 (9th Cir. 2012).
    In general, dismissal for lack of subject matter jurisdiction
    is without prejudice. See Kelly v. Fleetwood Enters., Inc.,
    
    377 F.3d 1034
    , 1036 (9th Cir. 2004) (dismissing a complaint
    without prejudice when the amount in controversy
    requirement was not met); Freeman v. Oakland Unified Sch.
    Dist., 
    179 F.3d 846
    , 847 (9th Cir. 1999) (order) (“Dismissals
    for lack of jurisdiction should be without prejudice so that a
    plaintiff may reassert his claims in a competent court.”
    (internal quotation marks and ellipsis omitted)). The theory
    undergirding the general rule is that “the merits have not been
    considered” before dismissal. Cooper v. Ramos, 
    704 F.3d 772
    , 777 (9th Cir. 2012). Plaintiffs have not satisfied the
    requirements of parens patriae standing. In theory, Plaintiffs
    could allege post-effective-date facts that might support
    standing. As a result, the complaint should have been
    dismissed without prejudice. See City of Oakland v.
    Hotels.com LP, 
    572 F.3d 958
    , 962 (9th Cir. 2009) (affirming
    dismissal but remanding to dismiss without prejudice); Kelly,
    
    377 F.3d at 1040
     (affirming with instructions to enter order
    of dismissal without prejudice).
    The judgment of the district court is AFFIRMED and the
    case is REMANDED with instructions to dismiss this action
    without prejudice.
