A King County judge has ordered prediction market platform Kalshi to cease operations for election, sports, and entertainment contracts in Washington state by September 2 or face daily fines.

Key Points

• Judge John McHale ordered Kalshi to geofence Washington users from non-financial markets, including politics, technology, and culture, by the September 2 deadline.
• The company faces a $120,000-per-day penalty for non-compliance, mirroring similar regulatory challenges Kalshi currently faces in Nevada.
• Kalshi may continue offering contracts related to commodities, climate, economics, and finance within the state.
• The court ruled that Kalshi willfully ignored a December 2025 notice from the Washington State Gambling Commission regarding unauthorized event-based contracts.
• Kalshi maintains that the U.S. Commodity Futures Trading Commission holds exclusive jurisdiction over its platform and is considering further legal appeals.

Why it Matters

This ruling highlights the growing regulatory friction between state gambling authorities and emerging prediction market platforms operating under federal oversight. The outcome sets a significant legal precedent for how states may restrict event-based wagering platforms that operate across multiple jurisdictions.
