March 19, 2026 Arizona has filed criminal charges against prediction market platform Kalshi for allowing users to bet on elections, escalating a broader regulatory push against event-based trading. At the federal level, lawmakers have introduced new legislation to ban bets on sensitive government actions, including war and military operations.
Arizona Attorney General Kris Mayes filed 20 misdemeanor counts against the New York–based company, alleging it is “operating an illegal gambling business” in violation of 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” Mayes said.
Kalshi disputes the charges, arguing its platform operates under federal oversight as a marketplace for regulated financial contracts. The company said the case relies on “paper-thin arguments” and warned against what it described as a “patchwork of inconsistent state laws” attempting to regulate a nationwide exchange.
If convicted, Kalshi could face fines of between $10,000 and $20,000 per violation.
The case reflects growing tension between state enforcement and federal oversight. Prediction markets like Kalshi position themselves as financial exchanges regulated by the Commodity Futures Trading Commission (CFTC), while states are increasingly treating certain contracts, particularly election-related bets, as gambling activity.
At the same time, pressure is building in Washington. Senator Chris Murphy and Representative Greg Casar have introduced the BETS OFF Act, which would prohibit betting on government actions, terrorism, war and other sensitive events. A separate proposal, the DEATH BETS Act, would bar CFTC-regulated entities from offering contracts tied to assassination, conflict or an individual’s death.
The legislative push follows scrutiny over trading activity linked to geopolitical events, including bets placed ahead of military operations involving Iran and Venezuela. These incidents have raised concerns about whether individuals with insider knowledge could profit from political or security decisions.
Prediction markets have expanded rapidly, with partnerships between platforms and major media organisations increasing their visibility and reach. However, their growth has outpaced clear regulatory frameworks. Arizona’s case is expected to be closely watched as an early test of how existing laws apply to these platforms.
