Arizona prosecutors have filed charges against prediction market operator Kalshi, alleging the company ran an unlicensed gambling operation and accepted illegal election wagers within the state.
Arizona Attorney General Kris Mayes on March 17 filed a 20-count criminal information in Maricopa County Superior Court against KalshiEx LLC and Kalshi Trading LLC, accusing the firms of violating state gambling and election laws. The case, identified as CR 2026-000173-001 or similar, centers on allegations that the platform accepted bets from Arizona residents without proper licensing.
Most of the charges are Class 1 misdemeanors under Arizona Revised Statutes § 13-3305(A)(1), which prohibits operating a business that accepts wagers on sports or other contingent future events. Four counts are Class 2 misdemeanors tied specifically to election wagering under § 16-1015, which bans betting on political outcomes in the state.
According to the filing, Kalshi’s platform facilitated wagers on a range of events, including professional and college sports games, Super Bowl outcomes, and proposition bets such as whether a specific player would score or whether a public figure would attend a game. The complaint also cites bets tied to political developments, including the 2028 presidential election, Arizona’s 2026 gubernatorial race, and other statewide contests.
State prosecutors allege the companies were not registered to conduct business in Arizona as foreign limited liability companies and operated in violation of state gambling statutes. Each count in the filing links the alleged conduct to Arizona’s broader legal framework governing wagering activities.
In a statement, Mayes said the platform’s classification as a prediction market does not exempt it from state law. “Kalshi may brand itself as a ‘ prediction market,’ but what it’s actually doing is running an illegal gambling operation and taking bets on Arizona elections, both of which violate Arizona law,” she said. Mayes added that Arizona would enforce its laws despite ongoing legal challenges brought by the company.
The charges mark the first known criminal action by a state against Kalshi, which is regulated at the federal level by the Commodity Futures Trading Commission (CFTC) as an exchange offering event contracts tied to real-world outcomes. The case adds to a growing conflict between state regulators and federally supervised prediction markets.
Days before the charges were filed, Kalshi initiated a federal lawsuit in the U.S. District Court for the District of Arizona seeking declaratory relief and an injunction against state enforcement. The company argues that the Commodity Exchange Act and CFTC oversight preempt state gambling laws, allowing it to operate nationwide without obtaining individual state licenses.
A Kalshi spokesperson said the allegations rely on “paper-thin arguments” and reiterated the company’s position that it operates as a federally regulated financial exchange, not a traditional sportsbook. The company has also filed similar legal challenges in other states, including Iowa and Utah, as part of a broader effort to establish federal preemption.
The case remains in its early stages, with no reported pleas or court dates. Legal proceedings are expected to test whether federal derivatives law overrides state gambling restrictions, a question with implications for prediction markets across the United States.
