Illinois Appeals Ruling Blocking Prediction Market Licensing and Taxes

Illinois’ effort to bring sports event contracts on federally regulated exchanges under its wagering system is now before the Seventh Circuit. Judge Martha Pacold’s injunction blocks the state from licensing, taxing or prosecuting those contracts while the appeal proceeds, leaving platforms such as Kalshi and Coinbase able to list them in Illinois for now. The order creates a temporary boundary between state enforcement and the exchanges’ federal regulatory status; the appeals court will decide whether that boundary can stand.

The injunction covers three state measures: the Sports Wagering Act, Illinois’ criminal gambling statute and an Illinois Gaming Board rule on internet wagering. It also blocks prediction-market fees in the state budget, which apply only to licensed providers. Pacold’s initial ruling had left the tax question open for further argument, so the later order reaches a significant part of the state’s plan that wasn’t settled at the outset. That distinction matters: a licensing requirement can shape who operates, while a tax can change the economics of each transaction.

Illinois’ licensing plan and tax revenue are on hold

The dispute concerns a framework that took effect in fiscal 2026, the first year Illinois imposed a per-wager tax on licensed sports betting. The Gaming Board had sent cease-and-desist letters to KalshiEX, Crypto.com and Robinhood on April 1, 2025, then to Polymarket on Jan. 27, 2026. The notices cited the Sports Wagering Act (230 ILCS 45) and the criminal code (720 ILCS 5/28-1(a)). Those letters show the state had already begun asserting authority over prediction-market operators before lawmakers added explicit language addressing their trades.

Lawmakers later folded prediction markets into that system. Gov. JB Pritzker signed the budget package, including SB 3019, on June 16. It classifies prediction-market trades as exchange wagers under the Sports Wagering Act and requires a Gaming Board license. The transaction tax rises after a licensee passes five million exchange wagers. That structure ties the cost of operating to both state approval and trading volume, giving the licensing question practical consequences beyond whether a platform can stay open.

In September, Republican Rep. Travis Weaver introduced House Bill 5811, which would repeal the exchange-wager tax while preserving the licensing rules. The proposal separates two policy choices the current dispute puts together: whether prediction markets need a state license, and whether their activity should generate this particular tax. Licensed online and mobile sportsbooks face a separate fee structure: an initial license costs $15 million for four years, with renewals costing $1 million every four years. The comparison helps explain the stakes for operators, though the figures describe sportsbook fees and shouldn’t be treated as the prediction-market tax itself.

Five sports-contract disputes converge at the Seventh Circuit

Pacold’s ruling stands out amid disagreement among courts over whether state gambling laws can govern sports contracts traded on exchanges regulated by the Commodity Futures Trading Commission. Before her early-October decision, Kalshi had lost 16 consecutive federal court rulings. Pacold found Illinois’ laws conflicted with federal law because they dictate “what can be sold, as well as where it can be sold and to whom.” Her reasoning puts the dispute on a question of regulatory authority: how far state rules can reach when a product is listed on a federally regulated exchange.

The appeals court now has five prediction-market cases involving sports event contracts, according to attorney Daniel Wallach: CFTC v. Wisconsin, Kalshi v. Raoul, Coinbase v. Raoul, United States v. Illinois and Ho-Chunk Nation v. Kalshi. The cases bring related challenges before the same court, which could make its handling of the Illinois appeal consequential beyond the immediate injunction. But a shared venue doesn’t mean each case presents identical parties or legal questions.

The CFTC sued Arizona, Connecticut and Illinois on April 2, 2026, over state actions against federally registered designated contract markets. Chairman Michael Selig said the agency would defend market participants against “overzealous state regulators.” The agency’s suit puts federal regulators directly into a conflict that had largely been framed as a dispute between state authorities and individual platforms. Its position adds institutional weight to the question of which rules apply to these contracts.

Wisconsin’s case is also headed to the Seventh Circuit after Judge William Griesbach ruled against the CFTC on July 29. Illinois is asking the court to reverse and vacate Pacold’s injunction. For operators, the ruling preserves access to Illinois customers for now; for the state, it suspends enforcement and a potential revenue source. Legislators had excluded the tax revenue from budget projections in anticipation of a legal challenge. The numbers here are underwhelming as a near-term budget story: the state had already planned around the possibility that the tax wouldn’t be available.

What the appeal could mean for operators and the state

This is more significant than it looks. The injunction doesn’t settle whether sports event contracts should be treated as gambling under Illinois law, or how federal oversight interacts with state licensing. It does determine what can happen while those questions are litigated: the state can’t use the covered measures against the contracts under the order, and platforms can continue listing them in Illinois for now. A reversal could change that operating picture; leaving the injunction in place would preserve the current pause while the broader dispute continues.

If you're working in this space, the immediate issue is the difference between a court order that preserves access and a final decision on the merits. Similar disputes over overlapping state and federal rules often turn on the wording of the laws and the scope of the federal framework, so the cases may not all resolve the same way. (And this is the part most people overlook: the tax and licensing questions can travel together politically while remaining distinct legal questions.) The Seventh Circuit will decide whether Illinois can restore its licensing and tax framework. For now, the state’s policy is on hold. The uncertainty remains.
