Arizona Sues Prediction Platform Kalshi for Alleged Illegal Gambling, State-Level Regulatory Conflict Escalates

Odaily News According to reports, Arizona Attorney General Kris Mayes filed criminal charges against prediction market platform Kalshi on Tuesday, accusing it of offering illegal gambling services within the state, including allowing users to place bets on sports events and election outcomes.

In a statement, Mayes stated that while Kalshi positions itself as a "prediction market," it is actually operating an illegal gambling business and allowing users to bet on Arizona elections, violating local laws. "No company gets to decide which laws it will follow."

Prosecution documents show that Kalshi faces a total of 20 criminal charges, including allowing Arizona residents to bet on various events such as professional and college sports events, player performance-related bets, and election results. The charges also include four counts related to election betting, involving the 2028 U.S. presidential election, the 2026 Arizona gubernatorial election, the 2026 Republican gubernatorial primary, and the 2026 Secretary of State election, among others.

Kalshi responded that these charges are "deeply flawed" and described the state attorney general's action as a "political maneuver." The platform has long argued that the event contracts it offers fall under the regulatory scope of the Commodity Exchange Act and should be overseen by the U.S. Commodity Futures Trading Commission (CFTC), and that federal regulation should take precedence over state laws.

Currently, Kalshi is facing similar regulatory challenges in multiple states including Ohio and Tennessee, and the legal dispute over whether prediction markets constitute gambling is intensifying.
