A state court in Washington this week ordered Kalshi to stop offering sports gambling and a variety of other wagers on its prediction market. King County Superior Court Judge John McHale issued a preliminary injunction in response to a lawsuit filed against Kalshi by the state of Washington.
« The order requires Kalshi to stop offering, accepting, or facilitating wagers on sports, elections, politics, entertainment, culture, tech and science, or mentions in Washington, » said a press release yesterday from Washington Attorney General Nick Brown. « Kalshi must implement an IP address and residency-based geofence by August 19 and a multi-source geofencing solution by September 2. This does not include all the wagers offered on Kalshi, but it includes a substantial part of their business, which in recent years has been increasingly driven by sports wagers. »
Kalshi is not licensed by the state Gambling Commission and is not registered to conduct business in Washington, the court order said. McHale found that Kalshi ads claiming « that it offers ‘legal betting’ in Washington state are likely to mislead a reasonable consumer that such gambling activities are legal under state law. »
