Illinois lawmakers have signed off on a budget measure that would create what appears to be the first state tax aimed specifically at sports event contracts traded through prediction markets. The provision was included in the wider revenue package contained in Senate Bill 3019, which cleared both chambers on June 1.

Under the legislation, “any wagers offered under this Act shall be subject to incur a transaction tax equal to 1.75% of each exchange wager.” The bill also establishes a higher rate for operators with significant activity. After a licensee reaches five million exchange wagers during a fiscal year, the transaction tax imposed under this subsection shall increase to 3.5% of each exchange wager.

Rather than taxing operator revenue, the proposal is built around transaction volume. Revenue generated by the tax would flow into the Sports Wagering Fund before ultimately being transferred to the state’s General Revenue Fund. The legislation states that the tax “shall be deposited monthly into the Sports Wagering Fund” and outlines the transfer process for certified amounts.

Analysis circulated by Fairplaygov indicates that the measure would apply to sports-based event contracts, while non-sports prediction markets would not be subject to the same tax structure.
