PHOENIX — 3/25/2026 - In a bold enforcement action that marks the first criminal case of its kind against a federally regulated prediction market platform in the United States, Arizona Attorney General Kris Mayes has charged online betting site Kalshi with operating an unlicensed gambling business and allowing prohibited wagers on state elections.
On March 17, 2026, Mayes' office filed a 20-count criminal information in Maricopa County Superior Court against KalshiEx LLC and Kalshi Trading LLC, the New York-based companies behind the popular Kalshi platform. All charges are misdemeanors, centered on allegations that Kalshi functioned as an illegal gambling operation without the required state license and facilitated bets on Arizona election outcomes, which state law explicitly bans.
"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," Mayes said in a statement. "No company gets to decide for itself which laws to follow." She added that Arizona "will not be bullied into letting any company place itself above state law."
The charges stem from what officials describe as evidence gathered through test bets placed by the Attorney General's office from within Arizona. Prosecutors allege the platform allowed users to wager on a range of events, including sports, news, and specifically future Arizona election results — practices that Mayes' team says mirror unlicensed sportsbooks while crossing into forbidden political betting territory under state statutes.
Kalshi, which operates under oversight from the federal Commodity Futures Trading Commission (CFTC) as a regulated prediction market, has pushed back forcefully. The company filed a preemptive civil lawsuit against Arizona and Mayes on March 12 in U.S. District Court, seeking to block enforcement actions and arguing that its platform involves legally distinct "event contracts" rather than traditional gambling. Kalshi has described the subsequent criminal charges as "meritless" gamesmanship intended to sidestep federal preemption questions.
This clash highlights growing tensions between innovative financial instruments like prediction markets — where users buy and sell contracts on real-world outcomes such as election results, economic indicators, or sports events — and state gambling regulators who view them as unregulated betting. Kalshi has faced similar pushback in other states, recently filing suits against Iowa and Utah as well.
Mayes, a Democrat elected in 2022, framed the case as a straightforward defense of Arizona law against out-of-state operators. "It’s my job to enforce the laws of Arizona," she stated. "I’m not afraid to lay down the law, even when it applies to predictive markets."
Legal experts note this represents an unprecedented criminal approach to a platform that has largely operated in a regulatory gray area at the state level, despite its federal registration. Outcomes could hinge on whether courts view Kalshi's contracts as securities-like derivatives protected by CFTC authority or as illegal wagers under Arizona's strict gaming and election statutes.
As the case proceeds in Maricopa County Superior Court, it could set a precedent for how states regulate the fast-growing prediction market industry amid debates over election integrity and gambling expansion. Kalshi has not yet publicly detailed its full defense strategy beyond calling the charges flawed.
Arizona residents with questions about the matter are encouraged to contact the Attorney General's office, which continues to monitor compliance with state gaming and election laws.
