Arizona Becomes First State to Bring 20 Criminal Counts Against Kalshi Over Alleged Illegal Gambling and Election Betting
Arizona became the first U.S. state to file a 20-count criminal complaint against prediction market Kalshi, alleging it operated an unlicensed online gambling operation by accepting bets on elections, political outcomes, college sports and individual player performance. The prosecution has escalated a jurisdictional fight with the CFTC—whose chair Michael Selig called the criminal case inappropriate and asserted federal oversight—after Kalshi’s request for a temporary federal block was denied by U.S. District Judge Michael Liburdi, and comes amid related legal actions in at least nine other states with mixed rulings.
📌 Key Facts
- Arizona is the first U.S. state to file criminal charges against Kalshi — a 20-count complaint — marking a significant escalation in regulation of the prediction-market platform.
- The complaint alleges Kalshi accepted bets on political outcomes (including election betting), college sporting events, and individual player performance, violating Arizona gambling law and the state's ban on election betting and operating as an unlicensed online gambling operation that allowed Arizona residents to bet without state approval.
- Arizona Attorney General Kris Mayes accused Kalshi of "running to federal court to try to avoid accountability."
- U.S. District Judge Michael Liburdi denied Kalshi’s request for a temporary block on Arizona’s action and ordered the company to show why its case belongs in federal court now that criminal charges have been filed.
- CFTC Chair Michael Selig publicly characterized the Arizona prosecution as a jurisdictional dispute, called it "entirely inappropriate as a criminal prosecution," said the CFTC is "watching this closely and evaluating its options," and the agency under the current administration has asserted exclusive oversight over Kalshi as a financial marketplace; Selig is currently the only sitting CFTC commissioner more than a year into President Trump's second term.
- The Arizona action is part of a broader, fragmented legal fight: at least nine other states have taken some form of legal action against Kalshi, with early state-court rulings in Nevada and Massachusetts favoring states while federal judges in New Jersey and Tennessee have ruled for Kalshi.
- Reporters place the dispute in the context of explosive growth and controversies in prediction markets — including large profits on wagers about events like Nicolás Maduro’s capture and Iran’s supreme leader’s death, and reported real-world harms such as death threats tied to bettors — which critics say illustrate the potential distortions and risks of these markets.
- ABC noted political and industry ties: Donald Trump Jr. is a strategic adviser to Kalshi, and Truth Social is launching its own crypto-based prediction market, Truth Predict.
