A Washington state court blocks Kalshi from offering sports prediction market contracts in the state, citing violations of state gambling laws, according to reporting from multiple outlets. The court grants Washington’s request for a preliminary injunction, preventing Kalshi’s market activities while the legal dispute proceeds. The decision follows similar restrictions against Kalshi elsewhere, with sources noting that courts in Massachusetts, Michigan, and Nevada have also issued orders limiting Kalshi’s operations. The injunction is framed around arguments that Kalshi’s contracts function as illegal gambling under Washington state law. The outlets describe the ruling as an early, temporary step rather than a final resolution, leaving open the possibility of later court proceedings. Overall, the coverage indicates that Washington’s action adds to a broader pattern of legal challenges affecting Kalshi’s ability to operate prediction markets across U.S. jurisdictions, as courts evaluate how state gambling statutes apply to the company’s offerings.
