- Updated Aug 23, 2026, 03:09 AM: Judge cites Commodity Exchange Act as likely preempting Minnesota's ban.
Court Grants Temporary Shield
A federal court ruled that Minnesota's prediction market ban likely violates federal preemption under the Commodity Exchange Act, issuing an order that allows Kalshi and Polymarket to keep serving Minnesota users while legal challenges proceed. The ruling arrived days before the state's enforcement deadline, preventing immediate disruption to the platforms' operations in the state.
Preemption Question at Center
The judge found that federal law—specifically the Commodity Futures Trading Commission's regulatory framework—likely preempts Minnesota's state-level ban, which would have classified unlicensed prediction market operations as felonies. The court decision does not resolve the underlying merits of the case or settle the precise boundary of which federal statutes apply to the platforms' business models. Both Kalshi and Polymarket now remain operational in Minnesota pending further litigation.
What Remains Unsettled
The ruling is preliminary and does not constitute a final judgment on the substance of Minnesota's law or the platforms' compliance obligations under federal statute. The case will continue through the legal system with the status quo preserved during proceedings, meaning the prediction markets can operate while courts determine whether state and federal rules can coexist or whether federal authority takes full precedence.
Why It Matters
For Traders
Prediction market liquidity in Minnesota remains available; near-term regulatory uncertainty is reduced, though full litigation outcome could still restrict access.
For Investors
Federal courts treating CFTC authority as primary over state-level crypto bans signals broader deference to federal commodities framework in litigation.
For Builders
Prediction market platforms can operate under assumption that federal commodities law governs; state-by-state crackdowns face higher legal barriers than previously apparent.
