  • Nevada Judge Blocks Kalshi's Prediction Market Operation Over Licensing
    March 22, 2026, 12:34 AM EDT. A Nevada judge has issued a temporary restraining order against prediction market operator Kalshi, stopping it from offering event contracts that allow residents to place financial bets on sports, elections, and entertainment. The order follows a lawsuit by the Nevada Gaming Control Board which contends Kalshi's activities amount to unlicensed gambling under state law. Kalshi argued the contracts fall under federal jurisdiction by the Commodity Futures Trading Commission, but the judge rejected this. A hearing for a potential longer injunction is set for April 3. This ruling adds to Kalshi's growing legal challenges, including similar blocks in Massachusetts and a criminal charge in Arizona. Nevada regulators emphasize their duty to protect the public from unlicensed gambling.
