A Washington state judge has ordered Kalshi, the CFTC-regulated prediction market platform, to stop offering a broad range of event contracts in the state, ruling that federal commodities law does not preempt Washington’s gambling statutes. The preliminary injunction, granted by King County Superior Court Judge John McHale, bars Kalshi from offering contracts tied to sports, elections, politics, entertainment, culture, tech, science, and “mentions.” Contracts involving commodities, climate, economics, and finance are exempt from the order.
Court rejects federal preemption argument
The amended order, signed Wednesday, sets the terms of the injunction McHale initially granted in July. The judge found that the Commodity Exchange Act does not preempt Washington gambling law and that the state had shown a likelihood of success on claims under three separate state laws. Washington Attorney General Nick Brown celebrated the ruling on X, stating, “We’re holding Kalshi accountable for running an illegal gambling operation.”
Kalshi has maintained that the Commodity Futures Trading Commission holds exclusive jurisdiction over its exchange, a position the Washington Court of Appeals declined to support when it denied the company’s request to stay the injunction. The legal battle highlights the ongoing tension between state gambling regulations and federally regulated prediction markets, a conflict that has intensified as platforms like Kalshi and Polymarket gain mainstream traction.
Geofencing deadlines and compliance requirements
Under the court’s order, Kalshi must implement initial IP-address and residency-based geofencing by August 19, followed by a more resilient GeoComply multi-source geofencing system by September 2. These measures are designed to prevent Washington residents from purchasing contracts covered by the injunction. The staggered deadlines give Kalshi time to deploy the technology while ensuring that the state’s prohibition is enforced promptly.

GeoComply, a firm widely used in the online gambling industry to verify user location, will provide the multi-source verification system. This approach reflects the court’s intent to create a reliable barrier that goes beyond simple IP checks, which can be circumvented through VPNs or other methods.
Why this ruling matters for the prediction market industry
The Washington ruling is a significant setback for Kalshi and the broader prediction market sector, which has been pushing for legitimacy and expansion. Kalshi operates under a CFTC license and has argued that its markets are legal financial derivatives, not gambling. However, this decision suggests that state regulators and courts are willing to challenge that interpretation, at least when it comes to consumer-facing event contracts.
For users, the immediate impact is clear: Washington residents will no longer be able to trade on sports, political, or entertainment outcomes through Kalshi. The ruling could also embolden other states to pursue similar actions, creating a patchwork of regulations that prediction platforms must work through. The outcome of any appeal could set a precedent for how state gambling laws interact with federal commodities oversight, making this a case worth watching for anyone involved in the industry.
Broader regulatory context
This ruling comes amid growing scrutiny of prediction markets globally. In Argentina, authorities have moved to block Polymarket despite the platform’s international growth, citing similar concerns about unlicensed gambling. Meanwhile, the CFTC has been reviewing its own rules for event contracts, with recent proposals suggesting a more restrictive stance on political betting. The Washington decision adds another layer of complexity, as it tests the limits of state authority in a domain that many assumed was federally preempted.
Kalshi has not yet indicated whether it will appeal the preliminary injunction to a higher court. The company’s legal team has consistently argued that its markets provide valuable data and hedging opportunities, and that they fall squarely within CFTC jurisdiction. However, the Washington Court of Appeals’ refusal to stay the injunction suggests that the state’s arguments have found some traction.
Conclusion
The Washington court’s order marks a key moment for prediction markets in the United States, underscoring the legal fragility of platforms that operate under federal commodities licenses but face state-level gambling prohibitions. With compliance deadlines approaching in the coming weeks, Kalshi will need to act swiftly to implement the required geofencing. The case’s progression through the appeals process will likely shape the regulatory market for prediction markets nationwide, making it a development that traders, regulators, and legal observers will be monitoring closely.
FAQs
Q1: What exactly did the Washington court order Kalshi to do?
The court issued a preliminary injunction barring Kalshi from offering event contracts related to sports, elections, politics, entertainment, culture, tech, science, and “mentions” to Washington residents. Kalshi must implement IP-address and residency-based geofencing by August 19, and a more comprehensive GeoComply multi-source geofencing system by September 2.
Q2: Why did the court reject Kalshi’s federal preemption argument?
Judge John McHale found that the Commodity Exchange Act does not preempt Washington’s gambling laws. He ruled that the state had shown a likelihood of success on its claims under three state laws, meaning the state’s consumer protection and gambling statutes can apply to Kalshi’s operations despite the company’s CFTC license.
Q3: Will this ruling affect users outside Washington?
The injunction applies only to Washington state. Users in other states can still access Kalshi’s markets, though the ruling could prompt other states to pursue similar actions. Kalshi’s geofencing measures are designed to block Washington residents specifically, so users elsewhere should not see immediate changes.
