Illinois Judge Blocks State From Enforcing Gambling Law Against Kalshi, Coinbase Sports Contracts
A federal judge in Illinois has granted prediction-market platforms Kalshi and Coinbase, along with the Commodity Futures Trading Commission, a preliminary injunction blocking the state from enforcing its gambling laws against their sports-related event contracts, according to Sports Betting Dime. Judge Martha M. Pacold of the U.S. District Court for the Northern District of Illinois issued the ruling on Friday, October 2, finding the plaintiffs are likely to succeed on the merits of their core argument: that the contracts qualify as federally regulated "swaps" under the Commodity Exchange Act, which would mean Illinois's gambling statutes are preempted where they conflict with that federal framework.
What the judge actually found
In her ruling, Pacold wrote that "many of the financial instruments at issue are likely swaps as defined by the Commodity Exchange Act — they just happen to be swaps that people find entertaining and fun," and concluded that "under the Act and precedent interpreting it, some Illinois law is likely preempted." She also found the plaintiffs had shown they would suffer irreparable harm without the injunction. Notably, the order drew a distinction between Illinois's attempt to ban the contracts outright and its separate transaction tax on prediction-market wagers: Pacold suggested the tax itself might survive even though the state's broader enforcement push does not, writing that the fee "might pose no necessary conflict just because they cause indirect economic effects," unlike laws that "regulate what can be sold, as well as where it can be sold and to whom."
Illinois had been attempting to apply its state gambling law to the sports-related contracts the same way several other states have against Kalshi over the past year. The ruling does not resolve the question nationally — it creates a split with a federal court in Wisconsin, where a judge denied the CFTC's parallel request for an injunction in July, ruling that similar event contracts likely do not meet the legal definition of a swap. The article notes the CFTC has already appealed that Wisconsin decision to the Seventh Circuit, and Illinois may now appeal this new ruling to the same appeals court, potentially putting both conflicting outcomes in front of the same panel of judges.
Why it matters
For now, the injunction means Kalshi and Coinbase can keep offering sports-related event contracts to Illinois users while the underlying legal fight continues. The case is one of a growing number of state-by-state battles over whether prediction markets offering sports outcomes are a federally regulated commodities product or state-regulated sports betting in disguise — a distinction that matters directly to licensed sportsbooks competing for the same customers under very different tax and regulatory burdens. Illinois's FY27 budget, passed in July, already includes a tiered transaction tax specifically targeting prediction-market operators, so the state retains at least one financial lever regardless of how the broader preemption question is ultimately resolved.
