Court Defeat: Washington State Blocks Prediction Market Operator Kalshi

The legal battle surrounding the classification of prediction markets has reached a new turning point in the state of Washington. A judge at the King County Superior Court has issued a preliminary injunction against KalshiEX, a platform specializing in event contracts. This ruling requires the company to immediately cease its activities within the state. The decision marks a significant victory for state gambling regulators, as the court rejected the argument that federal regulations over commodity exchanges override strict local gambling laws. Kalshi had contended that its status as a designated contract market under the Commodity Futures Trading Commission (CFTC) shielded it from state enforcement, but Judge John F. McHale disagreed.

This ruling is a substantial blow to the prediction market industry. These platforms allow users to wager on the outcomes of elections, sports, or economic indicators. While operators often characterize these as financial instruments for hedging risk, regulators increasingly view them as unlicensed gambling. The court in Washington clarified that federal status does not grant a license to violate the Washington Gambling Act. The judge found that the state is likely to prevail on claims involving professional gambling and illegal bookmaking.

Numbers and facts

The court order mandates that Kalshi must preserve all records related to its business in Washington. This includes platform logs, communications, marketing materials, and geolocation data proving where customers were located when placing bets. Such data is vital for assessing the scale of the company's unauthorized operations. The lawsuit alleges that Kalshi knowingly accepted funds from Washington residents to facilitate bets on sports, politics, and culture.

Washington is now the fourth state to successfully move against Kalshi's sports event contracts, following in the footsteps of Massachusetts, Nevada, and New York. In New York, Attorney General Letitia James and Governor Kathy Hochul celebrated a similar victory on July 8. Legal expert Daniel Wallach noted that states have been successful in 19 out of 23 recent court decisions regarding preliminary injunctions or restraining orders in the prediction market sector.

“This victory is the first step toward holding Kalshi accountable for their brazen violations of Washington law.” - Nick Brown, Washington Attorney General

Background

The core of the legal dispute remains the Commodity Exchange Act (CEA). Kalshi argued that the CEA preempts state gambling laws, effectively barring states from regulating their market. However, Judge McHale ruled that while the CEA gives the CFTC exclusive jurisdiction over certain transactions, it does not explicitly displace Washington’s power to enforce its gambling statutes. The judge cited savings clauses within federal law that preserve the jurisdiction of state courts and regulatory bodies. Furthermore, the court found that Kalshi’s advertising, which claimed the betting was legal in Washington, was likely to mislead consumers because the activities were never licensed under state law.

Although the CFTC granted Kalshi designated contract market (DCM) status in 2020, this federal recognition does not excuse the company from complying with individual state laws. The court was particularly concerned that Kalshi profits directly from facilitating wagers by collecting fees. Both parties have until August 3 to submit proposed language for the final injunction terms. This case highlights the growing friction between fintech-style betting platforms and traditional gambling enforcement agencies.

Why it matters for German players

For players in Germany, this case serves as a reminder of the strict limits on unauthorized gambling. Under the Interstate Treaty on Gambling 2021 (GlüStV 2021), prediction markets like Kalshi would require a specific license from the Gemeinsame Glücksspielbehörde der Länder (GGL) to operate legally. Simply having a financial license from another jurisdiction is insufficient. German players who use such platforms are not protected by the national LUGAS system, which monitors deposits and prevents excessive losses across different sites.

Furthermore, participants in unlicensed markets miss out on essential player protection features, such as the 1 Euro per spin limit for slots or the 1,000 Euro monthly deposit cap. Engaging with illegal operators also carries the risk of losing funds if the platform is suddenly blocked or its accounts are frozen by authorities, as seen in the Washington case. To ensure safety and legal certainty, German consumers should only play on sites listed on the GGL's official whitelist, where fair play and payouts are guaranteed by German law.

What it means for GGL-licensed casinos

Licensed operators under the GGL can view this international trend as a confirmation of their own regulatory environment. The protection of the legal market from gray-market competition is a priority for German regulators. When even US courts uphold state gambling laws against federal-level financial operators, it reinforces the GGL's stance on enforcing the GlüStV. Licensed casinos benefit from a market where everyone follows the same consumer protection rules, ensuring that innovation does not come at the expense of legality or player safety.
