Polymarket will stay open to potential enforcement action in Michigan after the federal court denied its request for a preliminary injunction in a June 17 ruling. Judge Paul L. Maloney of the Western District of Michigan rejected the company’s attempt to stop state officials from applying gambling laws to its sports event contracts while the lawsuit continues.
A State Case With National Stakes
This ruling doesn’t conclude the case. It leaves Polymarket without temporary protection and signals that the court remains skeptical of its federal preemption argument.
The case was filed by QCX LLC, which does business as Polymarket US. Polymarket claimed that its sports event contracts fall under CFTC oversight. It argued that federal oversight should preempt Michigan’s gambling enforcement.
However, Judge Maloney wasn’t convinced. According to the judge, Polymarket failed to show a strong chance of success, which is required for preliminary relief.
Why the Swap Argument Failed
The main controversy revolved around the classification of sports prediction contracts. Polymarket argued that the sports event contracts should be treated as swaps under the Commodity Exchange Act. Michigan’s arguments are straightforward: contracts tied to sports results may fall under gambling regulation.
Judge Maloney focused on the statutory definition of ‘swap’ and found Polymarket’s reading too broad. He said Congress used the swap framework to address financial market risks, not ordinary sports outcomes. That distinction now sits at the center of the US prediction market fight. If contracts for predicting the results of sporting events are regarded as federal financial instruments, there will be less power for state gaming authorities. If these contracts are perceived as gambling products, state regulators keep a major role.
Wider Pressure on Prediction Markets
This case decision comes as prediction markets face legal action by multiple states in the United States. Minnesota has gone further by passing a law that would criminalize operating or assisting prediction markets from August 1, though the CFTC is challenging it in federal court.
The CFTC has also moved the policy debate forward. On June 10, it issued an advance notice seeking comments on how prediction markets and event contracts should be treated under federal rules.
In effect, this means that for operators, compliance will now become even more challenging, as registration under federal law might not save them from regulatory action in some markets. Meanwhile, for gaming regulators, this is just further evidence that such sports outcome products cannot use financial language to circumvent state regulations.
Expert Take
The Michigan decision does not settle the national question, but it changes the tone of the dispute. Prediction markets can still argue for federal preemption, yet courts are showing caution when sports betting and consumer gambling laws are involved. Until Congress or a higher court gives a clearer answer, operators face a practical problem: the same contract may look like a financial instrument in one courtroom and a gambling product in another.
