Arizona has filed criminal charges against prediction market platform Kalshi, accusing the company of operating an illegal gambling business and accepting unlawful bets on elections.
The case, filed Monday, March 16, in Maricopa County Superior Court, marks the first time any state has brought criminal charges against the New York-based company, which has been at the center of a growing national dispute over how prediction markets should be regulated.
Arizona Attorney General Kris Mayes alleges Kalshi violated state law by allowing residents to place wagers on sports and political outcomes without proper licensing.
“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.
Prosecutors allege the platform accepted bets tied to multiple elections, including the 2028 presidential race and several 2026 Arizona contests, including races for governor and secretary of state, according to the filing. Gambling on elections is prohibited under Arizona law.
The charges include 20 counts related to operating an illegal gambling business and accepting unlawful wagers.
Kalshi pushed back on the allegations, arguing its platform operates as a federally regulated financial exchange rather than a sportsbook.
“States like Arizona want to individually regulate a nationwide financial exchange, and are trying every trick in the book to do it,” the company said in a statement, calling the case based on “paper-thin arguments.”
Prediction market platforms like Kalshi allow users to trade contracts tied to the outcome of real-world events, including sports games and elections. The company has maintained those contracts fall under the authority of the Commodity Futures Trading Commission, which regulates derivatives markets at the federal level.
The case escalates an ongoing clash between state regulators and Kalshi, which has received cease-and-desist orders from multiple states alleging it is operating as an unlicensed sportsbook. In February, a Massachusetts judge barred the company from offering sports-related contracts in that state on public health and safety grounds.
Kalshi recently filed a federal lawsuit seeking to block Arizona regulators from taking enforcement action, arguing federal law preempts state-level gambling restrictions. Mayes criticized the move, accusing the company of attempting to avoid compliance with state law by turning to the courts.
Legal experts say the case could have broader implications for how prediction markets are regulated nationwide, particularly as states push to assert control over platforms offering betting-style products outside traditional sports gambling frameworks.
