Trump Administration and CFTC Sue Three States Over Prediction-Market Gambling Rules as Tribal Casinos Call for Crackdown
The Trump administration, on behalf of the Commodity Futures Trading Commission, filed three federal lawsuits against Illinois, Connecticut and Arizona to block those states from treating prediction markets as gambling, arguing the markets are “swaps” under the CFTC’s exclusive authority and noting Arizona has already filed criminal charges against Kalshi. Tribal gaming leaders, warning that prediction markets threaten more than $40 billion in tribal gambling revenue, have called for congressional action and launched a legal defense fund as platforms like Kalshi, Polymarket and Robinhood insist their event contracts are futures appropriately overseen through CFTC rulemaking.
📌 Key Facts
