A US federal judge granted a preliminary injunction on July 27, blocking Minnesota from enforcing its new prediction market ban against CFTC-regulated platforms Kalshi and Polymarket US. According to the court order from US District Judge Katherine Menendez, the plaintiffs are likely to succeed on claims that the Commodity Exchange Act preempts the state statute, particularly for event contracts that qualify as swaps under CFTC jurisdiction. Minnesota's law was scheduled to take effect August 1 and would have imposed criminal penalties on anyone creating, operating, or advertising prediction markets in the state. This is an interim ruling, not a final outcome — the case will proceed to full litigation on the merits.
The decision matters because it establishes a legal pathway for federally regulated prediction markets to challenge state-level bans. Judge Menendez's reasoning suggests the CFTC's exclusive jurisdiction over swaps creates a federal floor that states cannot override with blanket prohibitions. Rhode Island has pursued similar legal action against prediction market operators, and other states may follow. The preliminary injunction sets a precedent that CFTC registration provides a defensible regulatory status, at least for contracts that meet the legal definition of swaps. The judge cautioned that not every event contract listed by the platforms may qualify, indicating the protection is contract-specific rather than platform-wide.
For traders, this removes a near-term regulatory overhang on prediction market platforms but does not resolve the broader state-versus-federal question. The sector still faces fragmentation risk — platforms may need to parse which contracts qualify for federal protection and which remain vulnerable to state enforcement. This ruling does not extend clear protection beyond the named CFTC-regulated entities. Traders holding exposure to prediction market infrastructure should expect continued volatility around state enforcement headlines until federal courts deliver a binding multi-state precedent or Congress clarifies jurisdiction.
Watch for the next procedural step in the Minnesota case and any parallel rulings in Rhode Island. If additional federal judges adopt the CFTC preemption argument, the sector gains a clearer operating framework. If a district court rules the other way, state-by-state compliance fragmentation becomes the base case and platforms face material operational drag. The timeline for a final ruling is not specified in the order.
