Illinois court shields Kalshi and Coinbase sports contracts for now

A federal judge has temporarily restricted Illinois from applying parts of its gambling regime to sports event contracts offered by Kalshi and distributed through Coinbase, handing the prediction-market companies a partial victory in their dispute over state and federal authority.

Judge Martha Pacold of the U.S. District Court for the Northern District of Illinois granted parts of the plaintiffs’ preliminary-injunction motions on October 2. She found that Kalshi’s core sports contracts are likely “swaps” under the Commodity Exchange Act and that Illinois requirements controlling their structure, availability and eligible customers likely conflict with federal regulation.

The order matters to crypto markets because Coinbase Financial Markets facilitates access to Kalshi-listed contracts for Coinbase customers. It also sharpens a broader jurisdictional fight over whether federally regulated prediction markets can offer sports contracts without obtaining separate state gambling licenses.

What the injunction covers

The consolidated litigation involves Coinbase, Kalshi, the United States, the Commodity Futures Trading Commission and other parties challenging Illinois officials. Illinois had sent cease-and-desist notices based on state sports-wagering and criminal-gambling provisions.

The court concluded that the challenged licensing rules directly regulate Kalshi’s market by restricting which sporting events can support contracts and who may trade them based on age and location. Applying those provisions would force the federally designated contract market to operate under Illinois-specific requirements, Pacold found.

That finding was preliminary. To obtain an injunction, the plaintiffs only had to show that they were likely to prevail, faced irreparable harm and satisfied the remaining equitable factors. The order is not a final judgment that every prediction contract is lawful, nor does it permanently prevent Illinois from regulating every activity associated with the companies.

The court also acknowledged a significant unresolved issue. Existing CFTC regulations restrict registered venues from listing contracts involving gaming, but the agency has not ordered Kalshi to remove the contracts at issue and supported the federal-jurisdiction position in this litigation. The February CFTC record cited by the court reflects the agency’s policy position; it is not itself a judicial resolution of the dispute.

Illinois fees remain in play

Pacold continued rather than resolved the challenge to Illinois’ prediction-market fees. The court record describes a charge of 1.75% on the first five million exchange wagers in a fiscal year and 3.5% thereafter, layered onto other state wagering charges.

Those percentages and thresholds describe the Illinois statutory structure presented in the litigation, not a measurement of Kalshi’s revenue, trading volume or actual tax liability. The judge requested more focused briefing on whether the fees merely create an economic cost—which may survive—or operate so severely that they effectively regulate the federally supervised market.

That distinction limits the immediate commercial effect of the ruling. Kalshi and Coinbase obtained protection from specified licensing and criminal provisions, but they did not secure a definitive exemption from the state’s fee system.

A ruling with narrow reach

The order applies to the consolidated Illinois cases and the sports-related contracts presented there. It does not establish a nationwide rule for Kalshi, Coinbase, Polymarket or other prediction-market operators. Courts addressing similar state challenges have not followed a uniform approach, leaving the boundary between commodities oversight and gambling regulation unsettled.

The litigation must still proceed to a merits decision, and the parties must address the injunction’s precise terms and the outstanding fee questions. Appeals could further change the result.

For crypto platforms expanding into event contracts, the immediate lesson is therefore limited but important: a federal court accepted, at the preliminary stage, that certain sports contracts may qualify as swaps and that state rules governing the market itself may be preempted. Whether that reasoning survives final judgment—and whether other courts adopt it—remains the central follow-up.
