A federal judge has paused a Minnesota law that banned prediction markets like Kalshi and Polymarket, granting a preliminary injunction to prevent the legislation from taking effect at the start of next month. U.S. District Judge Katherine Menendez ruled that platforms challenging the state statute demonstrated a strong likelihood of success in arguing that federal oversight preempts state-level prohibitions.
Federal Preemption and the CFTC Legal Challenge
Minnesota passed legislation earlier this year to outlaw prediction markets within the state, making it the first state to enact such a ban. According to reporting by NBC News, the state law drew immediate pushback from federal regulators and market operators. Platforms Kalshi and Polymarket joined the legal challenge as plaintiffs, arguing that the state overstepped its bounds by targeting federally regulated financial products.
The Commodity Futures Trading Commission (CFTC) also challenged the legislation, filing a lawsuit alongside the Trump administration. He argued that the legislation represented the most aggressive move by a state to shut down CFTC-regulated markets and undermine the federal regulatory regime established by Congress more than fifty years ago.
Court Ruling Protects Markets From Immediate Enforcement
In her ruling, Judge Menendez accepted the argument that federal law supersedes state bans and that the platforms would suffer direct financial and operational harm if the state enforced the measure. She wrote that the plaintiffs “have met their burden to show they are likely to succeed, at least in part,” according to NBC News.
The legal battle moved quickly ahead of the scheduled enforcement date. According to a letter sent to Judge Menendez by the CFTC, the agency warned that the clock was ticking as the law approached its effective date. The letter stated that if the court did not issue a decision or temporary stay by the close of business on Tuesday, July 28, the CFTC would view its motion as constructively denied and immediately begin the appeals process.
