Judge orders Kalshi to curtail Washington operations
King County Court has ordered Kalshi to geofence Washington state and stop offering most event contracts there. The preliminary injunction issued August 13, 2026 requires the CFTC-registered platform to limit access to commodity, climate, economic, and financial contracts. The ruling pierces Kalshi's federal preemption shield on state gambling law grounds. Kalshi must now halt operations for Washington users or risk contempt while it pursues appeal.
Washington becomes the fourth jurisdiction to punch through Kalshi's federal preemption defense, after Wisconsin, New York, and Utah. Each new state loss forces Kalshi and Polymarket toward the same expensive fork: build precise geofencing or absorb voiding risk on open contracts. The GeoComply deadline leaves nineteen days to implement. Traders now face contract validity that depends on geography, not CFTC registration.
Legal spend compounds across parallel fronts with no uniform standard. The platform's growth strategy assumed federal registration would hold state law at bay. That assumption is broken. Appeals are the only route to clarity, but circuit splits take months or years. Kalshi must monitor state courts, city councils, and the CFTC simultaneously.
