U.S. District Judge Paul L. Maloney of the Western District of Michigan has rejected attempts by prediction market operator Polymarket to block state officials from enforcing local gambling laws against its sports event contracts.
Polymarket, operating through QCX LLC, sought federal judicial intervention to halt regulatory enforcement led by Michigan Attorney General Dana Nessel and the Michigan Gaming Control Board. The platform argued that its sports outcome contracts constitute financial swaps governed exclusively by the Commodity Futures Trading Commission under the Commodity Exchange Act, thereby preempting state gambling statutes.
Court Dismisses Commodity Framework Defense
Judge Maloney rejected the statutory preemption argument, holding that Congress enacted the Dodd-Frank Act amendments to the Commodity Exchange Act to mitigate institutional financial market risks following the 2008 financial crisis, rather than to regulate consumer sports wagering. The court determined that extending the statutory definition of swaps or event contracts to cover sports scores and game outcomes stretches the text beyond its intended legal scope.
According to legal filings analyzed by De Silva Law Offices and court updates published by Michigan Gaming, the court found that federal commodity oversight does not strip state authorities of their traditional jurisdiction to enforce state gambling prohibitions against unlicensed sports contracts.
Multi-State Regulatory Pressure Builds
The Michigan decision mirrors legal setbacks for prediction market operators in multiple jurisdictions, including Massachusetts and Nevada, where state courts and regulators have similarly resisted claims that federal commodity designation confers broad preemption. Courts across jurisdictions may reach inconsistent rulings as they consider whether event-based derivatives override local gaming laws.
The Polymarket case followed Nessel’s enforcement action against Kalshi, which alleged that Kalshi’s sports event contracts constituted unlicensed gambling under Michigan law. The dispute illustrates the continuing question of whether federal authority over event contracts preempts state gambling enforcement.
For derivatives platforms operating under designated contract market structures, the ruling underscores that federal regulatory registration alone does not guarantee immunity from state gambling enforcement. Until federal legislation explicitly clarifies the statutory boundary between commodity swaps and sports wagering, prediction market platforms face continued operational exposure and state-by-state litigation risks.
