Washington Set to Block Kalshi Prediction Market by August 5

Quick Glance at the Facts

• A King County Superior Court judge granted Washington a preliminary injunction against the prediction market Kalshi, which the Attorney General’s Office announced on July 21, 2026.
• Judge John McHale found Kalshi likely broke the Washington Gambling Act and the Consumer Protection Act by running an illegal online gambling operation.
• A final order is due by August 5, 2026, and it is expected to force Kalshi to block Washington users.

Washington is close to shutting Kalshi out of the state after a King County judge found the prediction market likely runs an illegal online gambling operation. We break down what the court decided, the August 5 order that could cut off Kalshi for Washington players, and what stays the same for everyone else.

What the Washington Court Decided

Attorney General Nick Brown’s office first sued Kalshi in March 2026, arguing the platform broke the Washington Gambling Act and the Consumer Protection Act. Kalshi is a prediction market that sells event contracts on sports and many other outcomes, and it is licensed by the federal Commodity Futures Trading Commission (CFTC).

Judge John McHale sided with the state and granted a preliminary injunction, finding the state is likely to win and that Washington consumers would face substantial injury without one. The judge also rejected Kalshi’s main defense that CFTC oversight and the federal Commodity Exchange Act override state gambling law. Kalshi has pushed back, saying states have no authority to regulate prediction markets.

The August 5 Order Is the Next Step

The ruling does not cut off Kalshi right away. Both sides had until noon on August 3 to submit proposed terms and briefing, and the court plans to issue its final order by August 5. That order is expected to require Kalshi to geofence Washington, which means blocking anyone in the state from trading.

Kalshi can still ask for different terms by August 3, such as a settlement or an extension. The state is also seeking restitution for Washingtonians and civil penalties for each violation of the Consumer Protection Act.

What This Means for Washington Bettors

Washington residents who use Kalshi for sports, election, or event contracts may lose access once the order takes effect. Other prediction markets are not covered by this case, so Polymarket and Robinhood stay available for now. In-person sports betting at tribal casinos also continues as before, since that is the only legal sports wagering in the state.

Not much else changes, because Washington already runs one of the strictest setups in the country. As we cover in our Washington gambling guide, online gambling is mainly available via offshore operators.

GamblingNerd Take

Kalshi is no stranger to intense pressure. In the past month, Wisconsin and Minnesota have both battled against the prediction market, with varying scales of success. Washington is a different state, though, and has a much more strict history of gambling crack downs.

A federal license did not shield Kalshi from Washington’s own gambling law, and players trading event contracts should expect their access to end. If you hold Kalshi positions, consider getting out of the market before August 5th if geofencing does occur.
