AG Brown Wins Preliminary Injunction in Case Against Kalshi

Published Date: Jul 21, 2026

The Office of the Attorney General won a preliminary injunction Monday in its case against KalshiEX (Kalshi) after a King County Superior Court judge found that Kalshi likely violated the Washington Gambling Act and the Consumer Protection Act by running an illegal gambling operation in Washington.

“This victory is the first step toward holding Kalshi accountable for their brazen violations of Washington law. Kalshi padded their pockets as they promoted illegal betting on sports, elections, the total number of measles cases this year, what will witnesses say during a child trafficking hearing, and even natural disasters.” – AG Brown
