Illinois Passes Budget With 15% Tax on Fantasy Sports Operators and New Levies on Prediction Market Betting

Illinois lawmakers have passed a $55.9 billion fiscal year 2027 budget that introduces a 15% tax on daily fantasy sports operators and creates a new licensing framework for the DFS industry in the state. The budget was approved after overnight deliberations in Springfield and takes effect in the coming fiscal year, requiring platforms like DraftKings, FanDuel, and others to register with the state and pay the tax on their Illinois-sourced revenue. Democratic Representative Curtis Tarver, who shepherded the DFS provision, indicated that the licensing structure itself was something the industry had requested — suggesting major operators preferred formal state regulation over the ambiguity that had defined Illinois’s treatment of the category.

The DFS operator tax and a companion levy on digital asset transactions are projected together to generate approximately $65 million annually in new state revenue. The budget’s broader revenue package exceeds $800 million, with the balance coming from a new social media company tax, freezing of corporate net operating loss deductions, and other measures. The overall spending plan totals $55.9 billion and is described as essentially flat year-over-year in terms of new spending, with the revenue additions designed primarily to close a structural budget gap without raising income or sales taxes.

Prediction Markets Now Formally Taxed

The budget also imposes taxes on sports bets placed through prediction market platforms — a direct assertion by Illinois that companies like Kalshi and Polymarket are operating in the taxable sports wagering space. This comes despite ongoing federal litigation in which Kalshi has challenged the authority of Illinois and other states to regulate its markets, arguing that CFTC oversight of the platform’s contracts preempts state gambling law. By including the prediction market tax in a signed budget, Illinois is strengthening its legal and political position in that dispute, even if the enforceability of the tax remains subject to the outcome of the federal proceedings.

Lawmakers spent significant time debating how to handle prediction markets, reflecting the broader national uncertainty about the jurisdictional status of these platforms. The compromise embedded in the budget taxes the sports betting activity on prediction markets while leaving open questions about licensing and regulatory oversight for future resolution.

What This Means for Players in Illinois

For bettors and DFS players in Illinois sportsbooks and fantasy platforms, the new operator tax is not expected to appear as a direct line item on player accounts. DFS platforms typically absorb business taxes at the operator level. However, a 15% operator tax is a meaningful cost, and platforms may respond over time through adjustments to contest rake, promotional spending, or deposit match structures in the Illinois market.

The licensing requirement creates formal compliance obligations for DFS operators in Illinois, including registration fees and ongoing reporting requirements. For large operators like DraftKings and FanDuel, which already hold licenses in states including New York, New Jersey, and Michigan, the Illinois framework represents an additional but manageable regulatory layer. For smaller or emerging DFS platforms, the compliance costs could be more burdensome and may affect decisions about whether to maintain or expand Illinois operations.

The Illinois budget represents one of the most consequential state-level developments for the DFS and prediction market industries so far in 2026, establishing a precedent that other states may reference as they assess their own approaches to taxing and regulating these growing markets. Whether the 15% rate becomes an industry standard or triggers competitive pressure among states to offer lower tax regimes to attract operators will be worth watching as other state legislatures convene in the coming months.
