Judge Blocks Minnesota Prediction Market Ban for CFTC Exchanges
In brief
- Federal judge granted preliminary injunction blocking Minnesota SF 3432 from taking effect Saturday.
- CFTC-registered exchanges protected; enforcement hinges on whether contracts qualify as swaps under federal law.
- Senate race and geopolitical contracts likely qualify as swaps; sports betting and entertainment bets likely don't.
- CFTC sued multiple states; Minnesota AG opposes ruling as enabling predatory gambling apps.
- Ruling is preliminary; Minnesota may appeal or challenge specific contract classifications.
The Swap Question
Judge Menendez found the three plaintiffs likely to succeed on express-preemption claims. Her 44-page order bars enforcement against exchanges registered with the CFTC as designated contract markets, but the protection isn't blanket. Whether Minnesota's law is preempted turns on whether the trades at issue qualify as "swaps" within the meaning of the Commodity Exchange Act.
The judge drew a line based on economic consequence. Contracts on Senate races, the World Cup winner and the reopening of the Strait of Hormuz clear that bar because they concern events with clear potential economic, financial, or commercial consequences. Kalshi markets on who wins Love Island USA or on what announcers say mid-match likely do not. That split matters. It means some prediction markets get federal protection while others remain vulnerable to state enforcement.
The Broader Fight
The CFTC has sued multiple states including Illinois, Arizona, Connecticut, Wisconsin and Minnesota. The DOJ and CFTC filed suit in Minnesota within hours of the bill becoming law. Kalshi filed suit days later. All three parties wanted the same outcome: a preliminary injunction to halt enforcement.
The CFTC set a deadline for a ruling or stay by close of business Tuesday, after which it would treat its motion as constructively denied. The agency indicated it would seek interim relief from the Eighth Circuit if the deadline passed without a ruling. Judge Menendez beat that clock.
Minnesota's Response
Minnesota Attorney General Ellison said the state respectfully disagrees with the court's reading of the status quo. He characterized the status quo as allowing predatory gambling apps to proliferate. The preliminary injunction doesn't end the litigation—it simply pauses enforcement while the case proceeds. Judge Menendez found the statute may not be preempted in all its applications, leaving room for Minnesota to defend certain restrictions or appeal the ruling on narrower grounds.
The CFTC's challenge is facial, requiring showing there is no set of circumstances in which the law would be valid. That's a high bar, but Menendez cleared it for CFTC-registered exchanges. Whether that holds through trial, or whether Minnesota's appeal succeeds, remains open.
