A Washington state judge has ordered the prediction market platform Kalshi to halt operations for various event contracts, ruling that state gambling laws take precedence over federal regulations.

Key Points

• King County Superior Court Judge John McHale prohibited Kalshi from offering contracts related to sports, elections, politics, entertainment, and technology.
• Contracts involving commodities, climate, economics, and finance remain exempt from the court-ordered injunction.
• Kalshi must implement initial IP-based geofencing by August 19 and a comprehensive GeoComply system by September 2.
• Washington Attorney General Nick Brown stated the ruling holds the platform accountable for operating an illegal gambling business within the state.
• The court rejected Kalshi’s argument that federal Commodity Exchange Act jurisdiction preempts Washington’s specific state gambling statutes.

Why it Matters

This ruling highlights the ongoing legal friction between state-level gambling regulations and federally regulated prediction markets. The decision sets a significant precedent for how platforms like Kalshi must navigate conflicting jurisdictional authorities when expanding their services across the United States.
