Washington Court Blocks Kalshi Over State Gambling Law Claims

A Washington state judge recently issued a preliminary injunction against event contract platform Kalshi. The ruling halts the operator’s activities pending a full review of alleged violations of state gambling regulations.

Legal Basis of the Injunction

The court determined that Washington state officials are likely to succeed in their lawsuit. Judges concluded that Kalshi’s event contracts fall under state gambling statutes rather than federal jurisdiction. The decision directly rejects the company’s preemption defense, which argued that federal law overrides local regulatory enforcement.

Operational Impact

The injunction requires Kalshi to pause relevant operations while the litigation proceeds. State regulators will continue to examine whether the platform’s contract structures comply with established gambling frameworks. A final determination on the matter will follow the completion of the ongoing legal proceedings.
