When Missouri voters approved Amendment 2 in November 2024, they were approving a structure: a licensed market, a 10% tax on gross receipts, consumer protections, a minimum age of twenty-one. What they were not approving, in Attorney General Catherine Hanaway's reading, is a parallel set of products that produce identical outcomes without any of that architecture.
Crypto.com is the name that has not appeared in Gambity's coverage of the Missouri enforcement action, and it is the name worth examining. The cease-and-desist letters went to six platforms: Polymarket, Kalshi, Crypto.com, Novig, Underdog, and Robinhood. Crypto.com sits in a different category than the others. It is not a prediction market by origin or by market identity. It is a cryptocurrency exchange that has expanded into event contracts, which is precisely the pattern that makes Hanaway's enforcement frame interesting. The argument was never really about Kalshi or Polymarket specifically. It was about what the product does, regardless of what the company calls itself or where it came from.
Five of the six platforms face an additional allegation beyond the core preemption dispute: Hanaway's office contends that Polymarket, Kalshi, Crypto.com, Underdog, and Robinhood either permit users under twenty-one to access their products or lack adequate safeguards to prevent it. Novig alone escapes that specific charge. The age allegation matters because it is the kind of claim that survives a federal preemption argument. A court could find, as some have in analogous settings, that the Commodity Exchange Act governs the contract while state consumer protection law still governs who may hold it.
The preemption question is the center of every proceeding in this space right now, and Hanaway's office is arguing a position that two federal courts have at least partially credited: that online sports wagering platforms offering event contracts remain subject to state gambling laws, and that the CEA does not preempt that authority in this context. That reading is contested. Kalshi's own litigating posture, which has produced injunctions in Massachusetts and partial relief elsewhere, runs directly counter to it.
The legal standard that applies here is whether sports event contracts qualify as "swaps" within the meaning of the Commodity Exchange Act, because if they do, CFTC jurisdiction is exclusive and state enforcement is preempted under the Supremacy Clause. If they do not — or if a court finds that the state's interest in age verification and consumer protection survives preemption even where the underlying contract is federally regulated — then Missouri's thirty-day compliance deadline carries real enforcement weight.

The Commodity Exchange Act grants exclusive CFTC jurisdiction over contracts that qualify as 'swaps,' which preempts state enforcement under the Supremacy Clause. If event contracts do not meet the 'swaps' definition, or if state consumer protection interests survive preemption, then state gambling laws remain enforceable. Missouri Attorney General Catherine Hanaway's office argues that online event contracts remain subject to state law, a position two federal courts have partially credited.
Crypto.com is a cryptocurrency exchange that expanded into event contracts, not a prediction market by origin or identity. Attorney General Hanaway's enforcement frame targets platforms based on what their products do, regardless of company origin or self-identification. Crypto.com's categorization suggests the cease-and-desist attacks the functional outcome of the product, establishing a pattern that extends beyond platforms built as prediction markets from inception.
State consumer protection law governing who may access event contracts could remain enforceable even if the Commodity Exchange Act governs the contracts themselves. Five of six platforms named in the cease-and-desist—Polymarket, Kalshi, Crypto.com, Underdog, and Robinhood—face additional allegations of permitting users under twenty-one or lacking adequate age safeguards. A court finding in favor of Missouri's consumer protection authority would give real enforcement weight to the state's thirty-day compliance deadline.
The cease-and-desist targets six named platforms and creates immediate regulatory uncertainty about CEA preemption doctrine. Traders on Polymarket, Kalshi, and other event contract platforms can express market expectations about Missouri enforcement outcomes and federal court rulings on the 'swaps' question. The preemption dispute itself—whether event contracts qualify as federally regulated swaps—is resolvable through litigation and creates tradeable uncertainty for platforms operating in Missouri's licensed market.
