Illinois tax clock favours Weaver before Springfield returns

Travis Weaver introduced House Bill 5811 on a Wednesday, not because the Illinois legislature was in session, but because he wanted the argument running before it was. The bill would remove the definition of "exchange wager" from the Sports Wagering Act and repeal the transaction tax that sits at 1.75% on the first five million contracts and 3.5% on every one after that. The veto session opens in November. The regular session begins January 13. Weaver is trying to make the tax politically expensive before either window closes.

The structure of his problem is specific. Governor JB Pritzker signed Senate Bill 3019 as part of the fiscal-year 2027 budget. That budget allocated no projected revenue from the exchange wager tax — it allocated additional funds to the attorney general's office to defend the tax in court. Weaver identified this and said so directly: Illinois isn't collecting money from this provision, it is spending money to keep it alive. That is a different kind of political argument than the preemption fight Kalshi is running in federal court. It is an appropriations argument, and appropriations arguments sometimes move faster than constitutional ones.

The Illinois tax is structured to look like a regulatory framework rather than a revenue measure, which is partly what makes it legally interesting. A $15 million initial licensing fee, $1 million renewals, a tiered transaction tax — these are the architecture of a state claiming jurisdiction, not incidentally collecting it. The question a court would need to answer is whether a state can condition access to its market on a licensing regime that the Commodity Exchange Act arguably already governs at the federal level. Judge Locher's ruling in Iowa, which the newsroom has covered at length, found that the CEA's express preemption clause does not reach state gambling laws. That ruling helps Illinois defend its tax. It does not resolve whether the licensing requirement independently survives preemption analysis, because the licensing structure imposes obligations on a CFTC-regulated exchange that go beyond taxation.

I think the consensus is underweighting Weaver's window. The conventional read is that a Republican bill in a Democratic-controlled chamber dies in committee and the tax survives until a federal court says otherwise. That may be right on the vote count. It misses the revenue dynamic. Illinois built its budget without this money. If the tax generates nothing before January — and there is no indication it is generating anything — Weaver's argument that the legislature is paying a legal defense bill for a law that returns nothing becomes harder to dismiss. Legislators who voted for a budget that funded litigation over a non-performing tax will need an answer by the time appropriations debates open in the spring.
