US Government Sues Illinois to Block State From Policing Federally Regulated Prediction Markets
The US Department of Justice (DOJ) and the Commodity Futures Trading Commission (CFTC) sued Illinois on April 2, 2026, asking a federal courtroom to completely block the state from making use of playing legal guidelines to prediction market operators licensed as Designated Contract Markets (DCMs).
The grievance, filed beneath case no 1:26-cv-03659 within the US District Court for the Northern District of Illinois, names the state itself, Governor J.B. Pritzker, Attorney General Kwame Raoul, and 5 Illinois Gaming Board (IGB) officers as defendants.
The Preemption Argument
At the core of the lawsuit is a federal preemption declare. The CFTC argues that the Commodity Exchange Act (CEA), 7 U.S.C. § 2(a)(1)(A), grants the company unique jurisdiction over swaps and futures traded on federally regulated exchanges — jurisdiction that Illinois can not override.
The submitting traces that authority again to Congress’s deliberate effort in 1974 to substitute a fragmented state-by-state regulatory system with a single federal framework. The CFTC contends Illinois’s enforcement actions would recreate that very same patchwork, forcing DCMs to search licenses in all 50 states and making it unattainable to fulfill their federal mandate to present neutral nationwide entry to all eligible contributors.
The grievance challenges three particular Illinois statutes as preempted when utilized to DCMs: the Illinois Sports Wagering Act, the Illinois Criminal Code’s playing provisions, and the Illinois Gambling Act.
What Triggered the Lawsuit
The IGB despatched cease-and-desist letters to 4 CFTC-regulated entities, accusing them of unlicensed sports activities wagering beneath Illinois regulation. Kalshi, Crypto.com, and Robinhood acquired letters on April 1, 2025. Polymarket acquired its letter on January 27, 2026.
The IGB letters threatened civil and prison penalties and demanded the corporations cease providing occasion contract merchandise to Illinois residents with out an IGB-issued license. The CFTC argues that framing is legally flawed — occasion contracts structured as swaps fall beneath the CEA, not state playing codes.
As of the submitting date, no less than eight CFTC-regulated DCMs had collectively self-certified greater than 3,000 occasion contracts with the company. There are at present 25 energetic DCM designations within the United States, together with Kalshi, Polymarket, and Crypto.com.
Relief Sought and Broader Context
Plaintiffs are asking the courtroom to declare the three challenged Illinois statutes unconstitutional as utilized to DCMs and to challenge a everlasting injunction barring the state and its officers from any additional enforcement. The CFTC additionally seeks attorneys’ charges and prices.
The lawsuit arrives because the CFTC actively works to make clear its guidelines round prediction markets. The company revealed an advisory letter to DCMs on March 12, 2026, and on March 16, 2026, it revealed an advance discover of proposed rulemaking within the Federal Register soliciting public feedback on occasion contracts.
None of the named defendants had responded publicly to the grievance as of the time of submitting. The case units up a direct constitutional take a look at of whether or not states retain any authority to apply playing legal guidelines to exchanges already working beneath federal commodity regulation licenses.
