Wisconsin Court Deals Blow to CFTC Prediction Market Oversight

U.S. District Judge William Griesbach rejected the CFTC’s request for a preliminary injunction, finding that the agency failed to demonstrate it would likely succeed on the merits. The decision specifically impacts pending state-level lawsuits against Kalshi, Polymarket, Crypto.com, Robinhood, and Coinbase. Wisconsin Attorney General Josh Kaul has consistently characterized these platforms’ sports event contracts as unlicensed gambling, arguing that federal registration does not grant immunity from state statutes.

Conflict Over Jurisdictional Boundaries

Griesbach’s ruling asserts that Wisconsin’s gambling laws do not conflict with or face preemption by federal commodities regulations. This puts the CFTC in a difficult position, as it currently faces pressure from a coalition of 44 state attorneys general who argue that the agency has overstepped its authority by attempting to regulate markets traditionally governed by states. Ohio Attorney General Andy Wilson, who led the coalition, contends that Congress never authorized the federal government to overtake gambling oversight.

The industry now faces a fragmented legal landscape. While the Wisconsin decision empowers state authorities, a recent ruling in Minnesota saw U.S. District Judge Katherine Menendez temporarily block a state ban, favoring the CFTC’s preemption argument. With courts in Wisconsin and New York leaning toward state authority while others support federal supremacy, prediction market operators face mounting uncertainty. The CFTC has confirmed it will appeal the Wisconsin decision, keeping the dispute over the intersection of financial products and sports betting active in the courts.
