Judge Bars Kalshi From Most Washington Bets, a First Big State Crackdown on Prediction Markets
A King County judge ordered Kalshi to stop taking wagers on sports, elections, entertainment and more in Washington by Sept. 2, ruling the prediction market likely runs illegal gambling. It is the most aggressive state-level blow yet to the sector, hitting a business increasingly driven by sports bets. Kalshi must geofence Washington users or face $120,000-a-day penalties.
