meet its standards; or they may withdraw from that State’s market. In Exxon, the law posed a choice only for out-of-state firms. Here, the law presents a choice primarily—but not exclusively—for out-of-state businesses; California does have some pork producers affected by Proposition 12. See App. to Pet. for Cert. 205a. In Exxon, as far as anyone could tell, the law threatened only to shift market share from one set of out-of-state firms to another. Here, the pleadings allow for the same possibility—that California market share previously enjoyed by one group of profit-seeking, out-of-state businesses (farmers who stringently confine pigs and processors who decline to segregate their products) will be replaced by another (those who raise and trace Proposition 12-compliant pork). In both cases, some may question the “wisdom” of a law that threatens to disrupt the existing practices of some industry participants and may lead to higher consumer prices. 437 U. S., at 128. But the dormant Commerce Clause does not protect a “particular structure or metho[d] of operation.” Id., at 127. That goes for pigs no less than gas stations.
Think of it another way. Petitioners must plead facts “plausibly” suggesting a substantial harm to interstate commerce; facts that render that outcome a “speculative” possibility are not enough. Bell Atlantic Corp. v. Twombly, 550 U. S. 544, 555, 557 (2007). In an effort to meet this standard, petitioners allege facts suggesting that certain out-of-state farmers and processing firms will find it difficult to comply with Proposition 12 and may choose not to do so. See App. to Pet. for Cert. 198a, 208a, 313a. But the complaint also acknowledges that many producers have already converted to some form of group housing, even if they have not all yet met Proposition 12’s standards. Id., at 186a. From these facts, the complaint plausibly alleges that some out-of-state firms may face difficulty complying (or may choose not to comply) with Proposition 12. But from all anyone can tell, other out-of-state competitors seeking to
