Kalshi, Coinbase win partial ruling on Illinois sports contracts

Kalshi and Coinbase just won a meaningful round in the fight over who gets to regulate sports event contracts. On October 2, 2026, US District Judge Martha M. Pacold granted a partial preliminary injunction in Illinois, siding with the two companies and the Commodity Futures Trading Commission against state officials.

The win comes with an asterisk. The judge found that Illinois licensing requirements likely conflict with federal derivatives law, but she left the state’s transaction fee rules unresolved and told the parties to come back with proposed injunction terms.

What the court decided

The core question was preemption. That is the legal doctrine under which federal law overrides state law when the two collide.

Judge Pacold concluded that certain Illinois licensing requirements, including provisions under 230 ILCS 45, likely conflict with the federal Commodity Exchange Act. The CEA governs swaps and other derivatives, and it places them under the jurisdiction of the CFTC.

The plaintiffs’ argument hinges on classification. If Kalshi’s sports event contracts count as swaps under the CEA, they fall under exclusive federal oversight rather than state gambling law.

The court’s ruling supported that line of reasoning, at least at this preliminary stage. A preliminary injunction is not a final judgment. It reflects the court’s view that the plaintiffs are likely to succeed, which is encouraging for them but not the same as winning the case.

The fee question is a different story. The court did not settle whether Illinois can apply its transaction fee rules to these contracts and asked for further briefing on that issue.

The parties now have homework. They must propose the specific terms of the injunction, which will determine how far the state’s hands are actually tied in practice.

How Kalshi and Coinbase got here

Kalshi is not a newcomer to federal oversight. It has been a CFTC-registered designated contract market, or DCM, since November 2020.

The company began offering trading on sports event contracts in January 2025. These let users take positions on the outcomes of games, which looks a lot like sports betting to state regulators and a lot like derivatives trading to Kalshi.

Coinbase entered the picture in December 2025, when it announced a partnership with Kalshi to give its users access to those contracts.

The CFTC’s presence as a co-plaintiff is notable. Having the federal regulator argue alongside the companies signals that the agency views these contracts as squarely within its territory.

Illinois is one front in a much wider conflict. Similar challenges have played out across multiple states, and courts have issued conflicting opinions on whether sports-related contracts belong to federal derivatives regulators or state gambling authorities.

What this means for prediction markets and crypto platforms

The unresolved fee issue deserves attention. Transaction fees directly affect platform economics, and a state that loses on licensing but retains some fee authority could still shape whether operating there is profitable. Watch the forthcoming briefing closely.

The injunction terms matter too. A narrowly drafted order could leave Illinois with room to maneuver, while a broad one would more fully clear the way for Kalshi and Coinbase customers in the state.
