A federal court has rejected motions from the Commodity Futures Trading Commission and prediction market platform Kalshi in their legal fight against Wisconsin's restrictions on sports event contracts. The ruling is a clear loss for the CFTC and for platforms like Kalshi and Polymarket that rely on such contracts, handing a win to state-level efforts to crack down on the products.
The Wisconsin case
Wisconsin had moved to block sports event contracts within its borders, arguing they violate state law. The CFTC and Kalshi challenged that action, asking the court to stop the state's enforcement. But the judge denied their requests, meaning Wisconsin can continue its crackdown for now. The decision didn't address the underlying merits of the case, but it leaves the state's restrictions in place while the broader legal battle plays out.
What this means for prediction markets
For Kalshi and Polymarket, the ruling is a setback. Both platforms offer contracts tied to outcomes of sports events, a growing but legally murky area. The CFTC has argued that federal law preempts state bans, but this court disagreed — at least at this stage. Without a court order blocking Wisconsin, the platforms face a patchwork of state rules that could limit their user base and revenue. The decision also signals that other states may feel emboldened to pursue similar restrictions.
The CFTC's broader fight
The agency has been trying to assert authority over event contracts, including those for sports, elections, and other real-world outcomes. It has argued that these products fall under the Commodity Exchange Act and that state laws cannot override federal oversight. But this ruling undercuts that position. The CFTC now has to decide whether to appeal or adjust its strategy. For now, the loss weakens its hand in ongoing disputes with state regulators.
The case is far from over. The court's rejection of the motions doesn't end the lawsuit — it just means Wisconsin's enforcement can proceed while the legal arguments continue. The CFTC and Kalshi could still prevail on the core question of federal preemption, but that will take months or longer. Until then, prediction market operators are left navigating a fractured legal landscape.
