Judge Pacold leaves Illinois tax question open after swap ruling

A federal judge in Illinois handed prediction market platforms their clearest legal victory in months, then stopped short of finishing the argument.

U.S. District Judge Martha Pacold granted preliminary injunctions blocking Illinois from enforcing age restrictions, geographic limits, and trading rules against Kalshi, Coinbase, and the CFTC. Her reasoning was direct: sports event contracts offered by these platforms are likely swaps under the Commodity Exchange Act, and swaps are federal territory. Illinois had sought to build a full regulatory perimeter around these products — who could buy them, where, and at what age — using its gambling framework. Pacold found that framework preempted. The state's cease-and-desist letters to Kalshi, Polymarket, Crypto.com, and Robinhood, sent in April by Illinois Gaming Board Administrator Marcus Fruchter, now have no enforcement mechanism behind them.

The line Pacold actually wrote matters: "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." That sentence is doing legal work. It separates the product classification from the product's social character, which is precisely the move that state regulators have resisted. If a contract is a swap, the state's view of its entertainment value is irrelevant to its regulatory status.

But Pacold left one door open. Illinois planned a 1.75% per-wager tax on sports event contract trading, along with licensing requirements that the platforms estimated in the millions. The injunction does not clearly cover these. She wrote that taking a cut of profits "without more" might not pose the same conflict as regulating an entire market. That distinction — between revenue extraction and market structure regulation — is where the case goes next. The parties have until October 29 to submit a proposed injunction consistent with her opinion, and the tax question will likely drive that negotiation.

I have seen this structure before in multi-jurisdictional regulatory disputes: the preliminary injunction win feels decisive until you read the carve-out. A state that cannot tell a platform who to serve or where to operate can still impose a transaction levy significant enough to price smaller entrants out of the market. The outcome Kalshi achieved in this courtroom is real. Whether it forecloses Illinois's fiscal strategy is a different question, and Pacold has not answered it.

The contrast with Wisconsin is instructive. A federal judge there denied the CFTC a preliminary injunction, which means the same legal argument — that sports event contracts are swaps — has now produced opposite preliminary outcomes in adjacent federal districts. IAGR and NAGRA have asked the Supreme Court to resolve exactly this conflict. Pacold's ruling adds weight to that petition without resolving the circuit-level split that makes Supreme Court intervention the only path to a durable answer.
