Washington court blocks Kalshi sports contracts under preliminary injunction

King County Superior Court Judge John McHale granted a preliminary injunction against Kalshi, finding Washington was likely to succeed in its claims that the platform’s sports-related event contracts violate state gambling laws. The injunction is not due to take effect before 5 August, and the court directed the parties to submit proposed terms by 3 August. Kalshi said it disagreed with the court’s interpretation.
