The proposal would bar individual player props on college athletes from Washington-based teams; legislators took no vote at the committee hearing.

Kalshi has asked a Washington State Superior Court to reconsider a preliminary injunction covering its sports event contracts. The request cites new legal developments, but the available report gives no further details.
Kalshi began taking sports and political markets offline in Washington State. The outlet linked the sports shutdown to a court order.
Crypto.com-owned North American Derivatives Exchange, doing business as OG, sued Washington state officials in federal court on 22 July, seeking declaratory and injunctive relief. The company alleges that state enforcement of gambling laws threatens its sports event contracts, which it says operate under the Commodity Futures Trading Commission’s jurisdiction.
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.
