State AGs Challenge CFTC Authority Over Prediction Markets
In brief
- 41 bipartisan state attorneys general filed CFTC comments in April, arguing prediction markets function as de facto sportsbooks.
- Minnesota banned prediction market operations in May 2026; CFTC sued the state on May 19.
- Kalshi and Polymarket face regulatory pressure as states push gambling law oversight instead of commodities regulation.
The State Challenge
California and Minnesota's top prosecutors are questioning the CFTC's jurisdiction, setting up a legal showdown over which level of government controls prediction market regulation. A coalition of 41 bipartisan attorneys general submitted formal comments to the CFTC on April 30, arguing that prediction markets function as de facto sportsbooks and should be treated as gambling, not commodities.
The states' core argument is straightforward: the CFTC isn't equipped to handle gambling regulation. The attorneys general contend that the CFTC has no infrastructure, expertise, or mandate to deal with gambling addiction, consumer protection for bettors, or the social externalities that come with widespread access to wagering platforms. Minnesota Attorney General Keith Ellison was blunt about it. "States understand the social cost of gambling better than a commodities regulator ever could," he said on June 18.
Minnesota's Bold Move and Federal Response
Minnesota took action first. The state enacted a law in May 2026 that effectively banned prediction market operations within the state. The CFTC didn't back down. The agency sued Minnesota on May 19, arguing that the state law conflicts with federal authority. The CFTC's legal position rests on federal preemption: because prediction markets trade contracts the agency has approved, states cannot unilaterally criminalize them.
This is where the stakes get real for platforms.
What's at Risk for Prediction Market Platforms
Companies like Kalshi and Polymarket are caught in the crossfire. These platforms have built their business model on the premise that prediction markets are legitimate financial products operating under federal oversight. If states successfully establish that prediction markets fall under gambling law rather than commodities law, platforms would need to comply with dozens of state-level frameworks instead of operating under single federal oversight.
Critics also argue that these platforms currently avoid state consumer protections and tax obligations associated with traditional gambling. The outcome of this regulatory tug-of-war could reshape the entire industry — forcing platforms to either fracture their operations by state or exit markets entirely.
