A Washington state judge just ordered Kalshi to stop offering a wide range of event contracts to residents of the state. The ruling flatly rejected Kalshi’s argument that federal commodities law wipes out Washington’s gambling rules.
King County Superior Court Judge John McHale issued the injunction. It bars Kalshi from providing contracts tied to sports, elections, politics, entertainment, culture, technology, and science to anyone living in Washington. Contracts linked to commodities, climate, economics, and finance aren’t touched by the order — those can keep running. But the rest? Gone for Washington users, at least for now.
Washington Attorney General Nick Brown said the action came because the state sees Kalshi’s operation as illegal gambling, plain and simple.
Geofencing Deadlines and What Kalshi Must Do
To comply, Kalshi has two hard deadlines. First, IP-address and residency-based geofencing has to be live by August 19. Then, a GeoComply multi-source geofencing system has to follow by September 2. Both measures are meant to make sure Washington residents can’t reach the restricted contracts. It’s a pretty aggressive compliance timeline — less than three weeks between the order and the first technical cutoff.
The preliminary injunction rests on Judge McHale’s finding that the Commodity Exchange Act doesn’t override Washington’s gambling statutes. The state showed a strong likelihood of winning on claims under three specific state laws. Kalshi had pushed hard on the argument that the Commodity Futures Trading Commission — the CFTC — holds exclusive authority over its platform. The Washington Court of Appeals didn’t buy it. The appeals court refused to pause the injunction, which basically left Kalshi with no immediate escape route.
No further comment from Kalshi on how it plans to handle enforcement. Unclear whether the company intends to appeal further or just comply and fight later.
State vs. Federal: The Bigger Fight Behind the Ruling
The tension here isn’t just about Kalshi. Prediction markets have been operating in a genuinely murky legal space for years. Platforms that hold CFTC designation have generally argued that federal oversight is the whole story — that state gambling laws simply don’t apply to them. Washington’s lawsuit, and now Judge McHale’s ruling, punches a real hole in that theory.
The court’s position is that states retain the right to regulate what they consider gambling within their own borders, even when a platform runs under a federal commodities framework. That’s a significant stance. And the Washington Court of Appeals backing it up by refusing to stay the injunction makes it harder to dismiss as a one-judge outlier.
The amended order — signed just days ago — builds on the preliminary injunction McHale first granted in July. So this isn’t a brand new fight. It’s been moving through the courts for a while, and the state has been winning each round.
Kalshi’s legal argument has basically been: the CFTC governs us, so Washington can’t touch us. The court’s answer, so far, has been: no. State law on gambling carries real weight here, and the federal preemption argument hasn’t landed.
What happens if Kalshi misses the geofencing deadlines is probably the next question worth watching. Failure to comply could bring further legal action or penalties from Washington. The state has shown it’s willing to push this aggressively — filing the lawsuit, getting the injunction, beating back the appeals court stay request. It’s not likely to go quiet if the technical compliance drags.
The GeoComply requirement is worth noting specifically. GeoComply is a well-known geolocation compliance vendor used across regulated gambling and gaming markets. Requiring a named third-party system by a specific date means the court isn’t just asking Kalshi to do something vague — it’s setting a concrete, verifiable standard. Either the system is running by September 2 or it isn’t.
For Kalshi users in Washington, the practical effect is a hard block on a big chunk of what the platform offers. Sports contracts, election markets, political event contracts — those are arguably the most popular categories on prediction market platforms right now. Losing access to all of them is a significant restriction, not a minor tweak.
The broader prediction market industry has been watching cases like this closely. Kalshi isn’t the only platform navigating the state-versus-federal question. Polymarket and others operate in a space where the regulatory ground keeps shifting. A ruling that firmly says state gambling law survives federal preemption arguments — and that an appeals court agrees — sets a precedent that other states could pick up and run with.
Washington’s gambling statutes are now, at least in this court’s reading, fully alive and applicable to a CFTC-designated prediction market. That’s the core finding, and it’s the one that matters most going forward.
Kalshi must have the GeoComply system operational by September 2.

Why It Matters
This ruling highlights the ongoing tension between state gambling regulations and the emerging landscape of prediction markets, which often blur the lines between betting and speculative trading. By restricting Kalshi's offerings in key areas such as sports and politics, the decision could set a precedent that affects similar platforms operating in a patchwork of regulatory environments across the U.S., potentially stifling innovation and market participation in these sectors. As regulatory scrutiny intensifies, companies in the prediction market space may need to adapt their strategies to navigate these complex legal challenges.
