Washington Judge Blocks Kalshi Sports Contracts During Legal Fight
Judge rejects company's federal argument as Washington moves ahead with enforcement

A Washington state judge has granted the state's request for a preliminary injunction against Kalshi, preventing the prediction market operator from offering sports event contracts while the legal case moves forward.
The ruling marks another setback for Kalshi as courts continue to identify whether its sports event contracts fall under federal commodities law or state gambling laws. The court rejected the company's argument that federal oversight by the Commodity Futures Trading Commission (CFTC) prevents Washington from enforcing its own gambling laws.
Court Allows Washington to Continue Enforcement
Washington are arguing that Kalshi's sports event contracts operate like unlicensed sports betting and should therefore be subject to the state's gambling laws. Kalshi maintained that its contracts are federally regulated derivatives under the Commodity Exchange Act (CEA) and should not be regulated at the state level.
The judge sided with the state, granting a preliminary injunction that blocks Kalshi from offering the contracts in Washington while the case continues.
Federal Argument Falls Short
A key issue in the case was whether federal law overrides Washington's authority to regulate the contracts. Kalshi argued that the CEA gives the CFTC exclusive authority over its products, meaning states cannot take any action against them.
The court was not persuaded, finding that Washington had presented sufficient grounds for a preliminary injunction while the underlying legal questions are resolved. A final decision on the case will come at a later stage.
Pressure Continues to Build
The Washington decision continues to add to a growing number of legal challenges facing Kalshi across the U.S.
The company is currently involved in court proceedings in states including New York, Michigan, Nevada, Massachusetts, and California, with regulators and tribal gaming groups challenging the legality of its sports event contracts. While some courts have ruled in Kalshi's favour, others have allowed states to continue enforcing their gambling laws, leaving the legal landscape divided.
Another Important Case for Prediction Markets
The Washington ruling is another closely watched decision in the ongoing debate over prediction markets and sports event contracts. For Kalshi, the case represents another challenge as it continues to say that its products should be regulated exclusively under federal law.
For state regulators, the decision reinforces their position that they can take action against platforms they believe are offering unlicensed gambling products.
With several appeals still pending across the country, future court decisions are expected to play an important role in defining how prediction markets are regulated in the United States.
