“The plain language of Wisconsin’s commercial gambling statute seems to cover sports-related event contracts registered with the CFTC,” Griesbach noted. The state alleged that sports-related event contracts sold by those platforms constitute unlicensed gambling under Wisconsin law. Griesbach’s denial means Wisconsin can proceed with its civil enforcement while the federal case continues. A King County Superior Court judge in Washington State granted a preliminary injunction against Kalshi on 21 July 2026, as previously reported, finding that sports contracts fall under state gambling restrictions. In Wisconsin, the CFTC itself made that argument, backed it with a federal lawsuit and a request for injunctive relief, and still lost.
