U.S. Government Sues Illinois Over Prediction Market Rules, Seeks Permanent Injunction
The complaint, filed in the U.S. District Court for the Northern District of Illinois, names Gov. J.B. Pritzker, Attorney General Kwame Raoul, and the Illinois Gaming Board as defendants. Federal officials describe it as the first direct federal preemption lawsuit ever brought by the CFTC against a state over event contract markets.
The CFTC argues that under the Commodity Exchange Act, it holds exclusive jurisdiction over swaps and event contracts traded on registered designated contract markets. That authority, the agency contends, leaves no room for state gambling laws to apply to platforms operating within that federal framework.
Illinois regulators began moving against prediction market operators in April 2025, when the Illinois Gaming Board sent cease-and-desist letters to Kalshi, Robinhood, and Crypto.com, treating sports and political event contracts as unlicensed sports wagering under state law. In January 2026, the board issued similar warnings to Polymarket and notified licensed operators that facilitating prediction markets without a state license constituted illegal gambling.
The federal complaint characterizes those enforcement actions as an impermissible intrusion into federal authority. It argues that prediction markets are legally distinct from gambling under federal law, functioning instead as derivatives that serve hedging, price discovery, and information-aggregation purposes. The CFTC has overseen similar markets for more than two decades.
CFTC Chairman Brian Quintenz made his agency’s position clear in a February 2026 video address and a Wall Street Journal op-ed, warning that the CFTC would “no longer sit idly by” while states challenged its jurisdiction and telling would-be challengers they “will see you in court.” The April 2 lawsuit follows through on that statement.
The DOJ’s participation signals that federal enforcement interest in prediction markets extends beyond the CFTC alone. The two agencies have previously issued warnings about insider trading on prediction platforms and are conducting active investigations into suspicious trading activity tied to political and economic events.
Illinois is not the only state that has moved against prediction market operators. Nevada, Utah, and Massachusetts have taken similar steps, and those actions have produced a wave of litigation. In December 2025, Coinbase filed its own suit against Illinois officials, seeking a declaratory judgment and injunction on preemption grounds in a case styled Coinbase v. Raoul et al., No. 1:25-cv-15406.
The CFTC had previously filed amicus briefs in platform cases, including a Ninth Circuit proceeding stemming from Nevada, but had not directly sued a state until now. Illinois legislators have also proposed statutory measures targeting the sector. House Bill 5059 and Senate Bill 4168 would impose licensing requirements, ban participation by anyone under 21, or prohibit certain event contracts outright.
State regulators have framed sports-related prediction contracts as a loophole that allows operators to sidestep the licensed sports-betting market dominated by companies like FanDuel and DraftKings. The CFTC disputes that framing, drawing a legal line between wagering and derivatives.
A federal court ruling in the CFTC’s favor would affirm uniform national oversight under CFTC authority and potentially open prediction markets across all 50 states. Platforms like Kalshi and Polymarket have recorded billions of dollars in volume on events ranging from presidential elections to economic indicators to geopolitical outcomes.
Appellate courts in the Third, Fourth, and Ninth Circuits are handling related preemption cases, and the outcomes of those proceedings could shape how the Illinois case proceeds. If the dispute reaches the Supreme Court, it would set a binding national standard on the boundary between federal commodity regulation and state gambling authority.
