Kalshi and Coinbase have won a partial ruling in Illinois over their sports event contracts, after a federal judge found that the state's licensing requirements likely conflict with federal derivatives law.

The court, however, did not resolve every question raised in the dispute. The judge left the issue of transaction fees unsettled and ordered the parties to propose the terms of an injunction, according to the ruling.

The case centers on sports event contracts offered through Kalshi's exchange, with Coinbase named alongside the prediction-market operator as a party to the litigation. At stake is whether Illinois can require entities operating in the derivatives and event-contracts space to obtain state licenses, or whether federal law governing regulated derivatives markets preempts those requirements.

The judge's finding that state licensing rules likely conflict with federal derivatives law marks a significant procedural victory for the defendants. It signals the court's preliminary view that oversight of these instruments falls under the federal regulatory perimeter, rather than under a patchwork of state licensing regimes.

That said, the ruling is partial by design. By leaving the transaction fee question open, the court has deferred a decision on a narrower aspect of the dispute, and the instruction to both sides to propose injunction terms means the practical scope of any relief remains unresolved until the parties return with their proposals.

What the ruling means for the parties

For Kalshi, the decision preserves its ability to continue offering sports contracts in Illinois while the litigation proceeds, assuming the injunction that follows is framed consistently with the court's preemption reasoning. The company has positioned its event contracts as derivatives products traded on a regulated exchange, and the ruling supports that characterization against state-level challenges.

For Coinbase, the partial win reduces the immediate regulatory exposure it faces in Illinois over its involvement with sports contracts. The exchange has been expanding its product surface beyond spot trading into derivatives-adjacent offerings, and adverse state rulings in this case would have complicated that expansion in one of the country's larger markets.

The open question of transaction fees matters operationally. If the court later determines that fee structures tied to the contracts fall outside the preempted scope, the parties could still face constraints on how they monetize sports contracts in the state, even as the licensing question tilts in their favor.

The procedural picture

An order directing the parties to propose injunction terms is a common step when a court grants partial relief. It shifts responsibility to the litigants to draft language that implements the ruling, which the judge can then accept, modify, or reject. The final wording of the injunction will determine precisely which state requirements are blocked and which remain enforceable during the ongoing proceedings.

Because the judge's finding is framed in likelihood terms — the state rules "likely" conflict with federal law — the decision reflects a preliminary assessment rather than a final determination on the merits. The litigation continues, and Illinois retains the opportunity to defend its licensing framework as the case moves forward.

Broader context

The Illinois dispute is part of a wider contest over jurisdictional boundaries in digital-asset and event-contract markets. Prediction-market operators have argued that their products, once listed on federally regulated exchanges, sit within the federal derivatives framework. State regulators, by contrast, have sought to apply local licensing and consumer-protection statutes to the same activity.

A federal court signaling preemption on the licensing question adds a data point for other jurisdictions weighing similar actions against exchanges and prediction-market platforms. States that have pursued or considered enforcement against sports contracts will now watch how the injunction terms in this case are drawn, and whether the unresolved fee question narrows the practical reach of the defendants' win.

The next concrete step belongs to the parties. Kalshi, Coinbase, and Illinois must return to the court with proposed injunction terms, and the judge's adoption of a final injunction will determine the operative rules for sports contracts in the state while the underlying litigation proceeds toward resolution.
