Kalshi's partial win in Illinois leaves the state's fee rules in play

Licensing and fees are separate claims on an operator, and Judge Pacold split them ^[3][5]. Her preliminary finding covers the licensing provisions, including those under 230 ILCS 45 ^[3]. Whether Illinois can apply its transaction fee rules to the same contracts goes to further briefing ^[5]. The fee side is the one that reaches platform economics. According to Cryptobriefing, which reported the ruling, a state that loses on licensing but keeps some fee authority can still shape whether operating there is profitable ^[9]. The reporting does not give Illinois' fee rate, so the per-trade cost cannot yet be sized.

The contracts have been live for a long time while this question stayed open. Kalshi held its CFTC registration as a designated contract market for about four years ^[3] before it listed sports event contracts in January 2025 ^[7]. By the October 2, 2026 ruling it had about 21 months of sports trading behind it ^[1]. Coinbase's partnership, announced in December 2025 ^[8], was about 10 months old ^[2]. Over that stretch, courts in other states hearing similar challenges reached conflicting opinions ^[12].

The relief can still come out smaller than the headline. The parties have to propose the injunction's terms ^[4]. Cryptobriefing noted that a narrow order could leave Illinois room to maneuver, while a broad one would clear the way for Kalshi and Coinbase customers in the state ^[10]. The fee briefing can go Illinois' way. A preliminary injunction also reflects only the court's view that the plaintiffs are likely to succeed ^[11], so the licensing finding can be reversed before a final judgment.

I think the fee briefing will decide more about Illinois economics than the licensing finding did. As granted, the order does not reach fees ^[5]. A license the state cannot require costs an operator nothing further. A fee the state can apply is charged on every transaction, for as long as the operator serves the state ^[9].

The counter-case is that the plaintiffs' theory does not stop at licensing. If the contracts are swaps under the Commodity Exchange Act, they fall under exclusive federal oversight ^[13], and the CFTC is arguing that point as a co-plaintiff ^[2]. On that reading the court has only postponed a fee question it is likely to answer the same way. Two outcomes would prove the fee thesis wrong: proposed terms that come back broad, and a briefing that ends with Illinois barred from applying its fee rules. If both happen, the remaining risk in Illinois is whether the plaintiffs win at final judgment ^[11].
