Arizona Attorney General Files Criminal Charges Against Kalshi for Illegal Gambling and Election Wagering, March 2026

On March 17, 2026, Arizona Attorney General Kris Mayes filed a 20-count criminal information against KalshiEx LLC and Kalshi Trading LLC (collectively, Kalshi) in Arizona state court. The charges allege that Kalshi operated an unlicensed wagering business in Arizona and accepted bets on Arizona and federal elections. Kalshi had preemptively filed suit against the State of Arizona on March 12, 2026, seeking to avoid enforcement of state law.

Arizona law prohibits operating an unlicensed wagering business and separately bans election wagering outright. The criminal information includes four counts of election wagering, specifically accepting bets on the 2028 U.S. presidential race, the 2026 Arizona gubernatorial race, the 2026 Arizona Republican gubernatorial primary, and the 2026 Arizona Secretary of State race. The remaining counts allege that Kalshi accepted bets on professional and college sporting events and proposition bets on individual athlete performance without an Arizona gambling license. The Attorney General's office characterizes the Kalshi platform as an illegal gambling operation despite its self-description as a regulated prediction market.

Prediction market operators accepting wagers from Arizona residents face direct exposure under the state's gambling statutes regardless of any federal CFTC designation. Kalshi holds CFTC designation as a designated contract market (DCM), which authorizes it to operate certain event contracts under federal law. The Arizona charges raise the unresolved question of whether federal regulation of event contracts under the Commodity Exchange Act preempts state gambling prohibitions — a question Kalshi pursued in its March 12 preemptive lawsuit against Arizona. Operators of prediction market platforms with users in multiple U.S. states must analyze state gambling law independently of CFTC status.

The federal preemption question is actively litigated and unresolved. Kalshi's preemptive suit against Arizona filed on March 12, 2026 will likely present arguments that the Commodity Exchange Act's event contract framework displaces state gambling law for CFTC-registered DCMs. The Arizona AG's criminal filing creates parallel state criminal exposure while that preemption question works through the courts. Election wagering is separately banned under Arizona law with no apparent federal preemption argument available, as the CFTC itself has taken restrictive positions on election contracts.
