Washington Court Issues Final Ruling Requiring Kalshi to Block State Users From Election and Sports Markets

A King County Superior Court judge has issued a final order directing prediction market platform Kalshi to cease offering, accepting, or facilitating wagers on sports, elections, politics, and related categories for users in Washington state, after finding the activity likely violated the Washington Gambling Act and Consumer Protection Act by operating illegal gambling activities. The ruling builds directly on a preliminary injunction granted in July 2026 and follows enforcement actions initiated by the Washington State Attorney General, with the court requiring Kalshi to implement geofencing measures that prevent access from within the state.

Details of the Final Order

The order specifies two phases for compliance: Kalshi must activate IP and residency-based geofencing by August 19, 2026, followed by a more robust multi-source geofencing system no later than September 2, 2026, and observers note that these deadlines create a clear timeline for the platform to restrict Washington residents from participating in prohibited markets while the company continues operations elsewhere.

According to the Washington State Attorney General's news release, the judge determined that Kalshi's markets on elections and sports fell under the definition of illegal gambling under state law, and the final order reinforces this by prohibiting facilitation of such wagers through any means that reach Washington users.

Background on the Enforcement Action

Enforcement began earlier in 2026 when state regulators examined whether prediction market platforms were offering contracts that qualified as gambling under Washington statutes, and the Attorney General's office pursued legal steps that led to the July 2026 preliminary injunction before the court converted it into this permanent directive after reviewing evidence and arguments from both sides.

Those involved in the case point out that the Consumer Protection Act component addresses concerns about unfair or deceptive practices when platforms operate without proper licensing or disclosures required for gambling activities, while the core violation centers on the Gambling Act itself which classifies certain election and sports-related contracts as unauthorized betting.

Geofencing Requirements and Implementation

Kalshi must now deploy technology that identifies and blocks users based on IP addresses and residency data by the August 19 deadline, then upgrade to multi-source verification methods by early September 2026, and experts familiar with similar regulatory orders note that such phased approaches allow platforms time to test systems while ensuring broader protection against circumvention attempts through VPNs or other tools.

The court order does not restrict Kalshi from offering all markets nationwide, yet it limits the platform's ability to accept Washington participants in categories tied to sports, elections, and politics, creating a geographic carve-out that aligns with state authority over gambling activities within its borders.

Connection to State Gambling Laws

Washington's Gambling Act establishes strict controls on who may operate betting activities and which types of wagers receive approval, and the judge's finding that Kalshi likely operated illegal gambling means the platform's election and sports contracts triggered enforcement because they lacked the necessary state licenses or exemptions that apply to other financial or entertainment products.

People who track regulatory developments in this sector often see similar actions where prediction platforms face state-level challenges even as they secure federal approvals from the Commodity Futures Trading Commission, and the Washington case illustrates how overlapping jurisdictions can produce distinct compliance obligations at the state level.

Next Steps and Compliance Timeline

Kalshi faces the immediate task of rolling out the required geofencing by the specified August and September 2026 dates, and failure to meet these benchmarks could trigger additional enforcement measures including potential contempt proceedings or further restrictions outlined in the order.

The Attorney General's office continues to monitor compliance through its consumer protection division, and court documents indicate that the final order serves as the conclusive resolution of the injunction phase while leaving open the possibility of broader litigation if violations persist.

Conclusion

This ruling establishes a binding requirement for Kalshi to exclude Washington users from specific prediction markets through technical controls that activate in phases during August and September 2026, and it reflects the state's ongoing application of existing gambling statutes to emerging platforms that combine elements of trading and wagering. The decision stems entirely from the July 2026 preliminary findings and the Attorney General's enforcement efforts, resulting in a clear framework for blocking access to sports, election, and political contracts for residents of the state.
