Federal Court Halts Minnesota’s Prediction-Market Ban
A federal judge has issued a preliminary injunction to temporarily block Minnesota from enforcing its new felony law against regulated prediction markets. The ruling, handed down by Judge Katherine Menendez, arrives just days before the state’s statute was scheduled to take effect on August 1. By granting this motion, the court provides a temporary legal shield for federally regulated exchanges, such as Kalshi and Polymarket US, as they challenge the state's authority to criminalize their operations.
The Conflict Between State Law and Federal Oversight
The core of the legal dispute rests on whether federal law takes precedence over Minnesota’s attempt to ban prediction-market activities. Judge Menendez found that the plaintiffs are likely to prove that the Commodity Exchange Act (CEA) preempts certain aspects of the state’s new law. Under federal law, the Commodity Futures Trading Commission (CFTC) holds exclusive jurisdiction over "swap" transactions conducted on designated contract markets. The court noted that many event contracts—such as those involving Senate elections or significant economic consequences—qualify as swaps and should therefore be governed by federal regulations rather than state criminal statutes.
Selective Protections and Ongoing Legal Uncertainty
While the injunction is a significant win for regulated platforms, it does not offer universal protection for all participants in the prediction-market ecosystem. The order specifically protects CFTC-designated contract markets, but it does not expressly shield individual customers, independent advertisers, or third-party service providers from the state law. Additionally, the judge signaled that not all contracts may qualify for federal protection, distinguishing between serious economic events and trivial markets like reality television outcomes. As Minnesota officials vow to continue defending the law, this case underscores a growing national debate over the boundary between state gambling enforcement and federal commodity oversight.
