A federal judge ruled that Minnesota’s law banning prediction markets likely runs afoul of the Commodity Exchange Act, granting a preliminary injunction against the law to Kalshi, Polymarket and the Commodity Futures Trading Commission.
Judge Katherine Menendez, of the U.S. District Court for the District of Minnesota, ruled Monday that Minnesota’s recently passed law that would ban prediction market operators from offering their products in the state seems to be preempted by the federal CEA, and that the companies and federal regulator “are likely to succeed” in showing so after a full trial.
Kalshi, Polymarket and the CFTC sued Minnesota earlier this year after the state passed the law criminalizing the operation of prediction markets, arguing that the statute violated the CFTC’s jurisdiction to oversee “swaps,” which prediction market contracts are structured as.
In her ruling, Judge Menendez said that the three parties had shown they were likely to succeed in their arguments that the law underpinning U.S. commodities exchanges preempts the state law, that the CFTC has jurisdiction over these products and that the plaintiffs would likely succeed on the merits of the case.
