Kalshi Faces 20 Criminal Charges in Arizona as Congress Moves to Ban War Bets
Arizona Attorney General Kris Mayes filed 20 criminal counts against prediction market operator Kalshi on March 17, 2026, alleging the platform ran an unlicensed gambling business and accepted illegal election wagers from state residents. The charges, brought against KalshiEx LLC and Kalshi Trading LLC in Maricopa County Superior Court, represent the most serious state-level enforcement action against a federally registered prediction market to date. They arrived on the same day Democratic lawmakers in Washington introduced legislation targeting war-related event contracts, compressing what had been a slow-building regulatory debate into a single, consequential news cycle.
The Anatomy of the Arizona Charges
Of the 20 criminal counts, four relate specifically to election wagering, which Arizona law prohibits outright rather than merely requiring licensure. The contracts at issue covered the 2028 presidential race, the 2026 Arizona gubernatorial election, the 2026 Republican gubernatorial primary, and the Arizona Secretary of State contest. Additional counts address wagers on professional and college sporting events, proposition bets on individual player statistics, and a contract tied to whether the federal SAVE Act would become law.
Mayes was direct in framing the enforcement rationale: “No company gets to decide for itself which laws to follow.” Kalshi’s response was equally unambiguous. A company spokesperson described the criminal case as built on “paper-thin arguments” and maintained that the Commodity Futures Trading Commission holds exclusive jurisdiction over its event contracts, rendering state-level enforcement preempted under federal law.
That jurisdictional argument has produced inconsistent results across the judiciary. A federal judge in Ohio recently denied Kalshi’s request for a preliminary injunction, ruling that the company’s interests were “dwarfed by Ohio’s interest in exercising its police power.” A federal judge in Nevada and a Massachusetts state court reached similar conclusions on sports-related contracts. A Tennessee federal judge, however, temporarily blocked state regulators from enforcing a cease-and-desist order, illustrating that the legal landscape remains genuinely unsettled.

Kalshi filed a preemptive federal lawsuit against Arizona on March 12, five days before the criminal charges landed, mirroring suits it filed against Iowa and Utah within the same three-week period. Mayes called the pattern deliberate: “Kalshi is making a habit of suing states rather than following their laws.” The CFTC, under Chairman Mike Selig, has advanced rulemaking asserting exclusive federal jurisdiction over event contracts, providing Kalshi with institutional cover for its legal strategy. Whether that cover holds in the criminal context is a question courts have not yet answered at the appellate level.
Congressional Pressure and the Insider-Trading Dimension
Separately, Texas Representative Greg Casar and Connecticut Senator Chris Murphy introduced the BETS OFF Act, which stands for Banning Event Trading on Sensitive Operations and Federal Functions. The bill targets contracts whose outcomes hinge on government action, including military operations. Murphy flagged “highly unusual” Polymarket positions opened ahead of reported planning for U.S.-Israeli strikes on Iran, suggesting participants may have held advance knowledge of classified decisions. This concern about prediction market insider trading on war-related contracts has been building for weeks and now has formal legislative expression.
A Structural Inflection Point
The simultaneity of these developments is structurally significant. Kalshi is contesting criminal charges in one of the largest U.S. states while simultaneously defending its federal preemption theory in multiple jurisdictions. Polymarket faces a nationwide block in Argentina, following regulatory actions in France, Germany, Italy, Australia, Singapore, and several other markets. Israeli prosecutors have already charged individuals over alleged misuse of classified military intelligence to place bets on that platform.
The prediction market industry entered 2026 with considerable regulatory tailwind from a CFTC sympathetic to event contracts. What March 17 demonstrated is that federal goodwill does not automatically constrain state attorneys general, and that congressional sentiment, at least among minority-party lawmakers, is moving in a restrictive direction. The resolution of Kalshi’s federal preemption argument, likely at the appellate level over the next 12 to 18 months, will determine whether these platforms can operate as national exchanges or must negotiate a fragmented state-by-state licensing regime. Until that question is settled, the legal and political costs of operating in this space will continue to accumulate.
