Illinois is moving to tax prediction market trades at rates up to 3.5% under Senate Bill 3019, a measure that has already drawn a federal lawsuit from Kalshi and the Commodity Futures Trading Commission. The bill also raises taxes on sports betting operators, a policy that demonstrably backfired in 2025 when a similar hike caused bets placed in Illinois to fall 21% year-over-year within twelve months.

Illinois Senate Bill 3019 Creates a Two-Tier Prediction Market Tax Structure

How the Tax Rates Are Structured

Senate Bill 3019 establishes a tiered transaction tax specifically targeting prediction market activity in Illinois. The first five million transactions on a given platform face a 1.75% levy, and every transaction beyond that threshold is taxed at 3.5% [1]. This two-tier design mirrors the graduated tax structures Illinois has applied to sports betting operators, signaling a broader legislative strategy to extract revenue from the state’s growing speculative trading sector.

Prediction markets are platforms where participants buy and sell contracts tied to the outcome of real-world events, from election results to economic indicators. Unlike traditional sports betting, these platforms operate as commodity futures exchanges under federal law, which places them squarely under the regulatory authority of the Commodity Futures Trading Commission rather than state gambling regulators. That jurisdictional distinction is central to the legal challenge now pending against Illinois.

The bill does not cap total tax liability, meaning high-volume platforms could face the 3.5% rate on the vast majority of their Illinois transaction volume. For context, a platform processing ten million Illinois transactions in a year would pay 1.75% on the first five million and 3.5% on the remaining five million, producing a blended effective rate well above 2.5% on total volume.

What Prediction Markets Are and Why Illinois Wants to Tax Them

Kalshi, founded in 2018 and headquartered in New York, is the most prominent CFTC-regulated prediction market exchange operating in the United States. Kalshi received CFTC designation as a Designated Contract Market in 2020, allowing it to offer event contracts to U.S. residents legally. The platform saw significant growth following the 2024 U.S. election cycle, when political prediction markets attracted mainstream attention and substantial trading volume.

Illinois legislators appear to view prediction market platforms as a new revenue source comparable to sports betting. The state collected over $200 million in sports betting tax revenue in fiscal year 2024, and prediction markets represent a fast-growing adjacent category. Senate Bill 3019 bundles the prediction market tax with increased levies on sports betting operators, suggesting the Illinois General Assembly is treating both as gambling-adjacent activities regardless of their federal regulatory classification [1].

The bill’s sponsors have not publicly detailed the projected revenue from the prediction market tax specifically. However, the structure of the tiered rate suggests the legislature anticipates significant transaction volumes from platforms like Kalshi operating in the state.

Kalshi and the CFTC File Lawsuit Against Illinois Over Senate Bill 3019

The Federal Preemption Argument

Kalshi and the Commodity Futures Trading Commission have filed a lawsuit against the state of Illinois challenging Senate Bill 3019, and the case is currently pending in federal court [1]. The core legal argument centers on federal preemption: because Kalshi operates as a CFTC-regulated Designated Contract Market under the Commodity Exchange Act, Illinois may lack the authority to impose state-level transaction taxes on federally regulated commodity futures activity.

The Commodity Exchange Act grants the CFTC exclusive jurisdiction over futures contracts and options on commodities traded on designated contract markets. If a federal court agrees that prediction market event contracts qualify as commodity futures under this framework, Illinois’s attempt to tax those transactions could be struck down as an unconstitutional interference with federal regulatory authority. This is not a novel legal theory: states have previously lost attempts to regulate federally preempted financial instruments.

The CFTC’s direct participation in the lawsuit is notable. Federal regulators rarely join private companies in suing state governments, and the agency’s involvement signals that the CFTC views Illinois’s tax as a direct challenge to its exclusive regulatory domain over prediction markets. The outcome of this case could set a national precedent affecting every state that considers similar legislation.

Industry Opposition Beyond the Courtroom

The Sports Betting Alliance, a trade group whose members include DraftKings and FanDuel, has separately opposed the sports betting tax increases included in Senate Bill 3019. The Sports Betting Alliance argues that higher operator taxes will push bettors toward unregulated offshore platforms, undermining the consumer protection goals that legalized sports betting was designed to achieve [1].

DraftKings and FanDuel together hold the largest market share in Illinois’s legal sports betting market. Both companies have publicly stated that tax increases at the rates proposed in Senate Bill 3019 would force them to reduce promotional spending and potentially withdraw from certain market segments. The Sports Betting Alliance’s position aligns with the empirical evidence from Illinois’s own recent history, which shows that tax hikes on betting operators produce measurable market contraction rather than sustained revenue growth.

Illinois’s 2025 Sports Betting Tax Hike Already Produced a 21% Drop in Activity

The Data Illinois Legislators Are Ignoring

Illinois raised taxes on sports betting operators in May 2025. By May 2026, exactly twelve months later, the number of bets placed in Illinois had fallen 21% year-over-year, and the total sports betting handle, meaning the gross amount wagered, had declined 10.2% [1]. These are not projections or industry estimates; they are reported figures from Illinois’s own regulated market data.

The 21% drop in bets placed is particularly significant because it reflects consumer behavior, not just operator decisions. When operators face higher taxes, they typically reduce bonuses, increase margins, and offer less competitive odds. Bettors respond by placing fewer wagers or migrating to offshore books that face no Illinois tax burden. The net result is that Illinois collected higher per-transaction taxes on a smaller transaction base, and the state’s total regulated betting activity shrank.

A 10.2% decline in the sports betting handle within one year of a tax increase represents one of the sharpest post-tax contractions recorded in any U.S. state’s legal sports betting market. The prediction market tax in Senate Bill 3019 risks replicating this outcome in a sector that is still in its early growth phase nationally.

Illinois Gambling Tax Rate Comparison Under Senate Bill 3019

The prediction market tax is structured as a per-transaction levy rather than a percentage of operator revenue, which makes it fundamentally different from how Illinois taxes casinos and sports books. A per-transaction tax hits platforms regardless of whether a given trade is profitable for the operator, creating a cost burden that scales directly with user activity rather than with business success. This structure is particularly punishing for high-frequency, low-margin event contract trading.

Illinois’s broader gambling tax environment is already among the more aggressive in the Midwest. The state’s top casino tax rate of 50% on adjusted gross receipts applies to the highest-revenue properties, and the sports betting tax increase in 2025 pushed Illinois above the national average for sports betting operator levies. Senate Bill 3019 would extend this high-tax posture into the prediction market sector before that sector has established stable revenue baselines in the state [1].

What Illinois’s Prediction Market Tax Means for Financial Privacy Advocates

For the Monero community and privacy-focused financial participants, the Illinois prediction market tax illustrates a pattern that extends well beyond state tax policy. Every transaction on a regulated prediction market platform like Kalshi is recorded, reported, and subject to state and federal oversight. Senate Bill 3019 would add a new layer of state-level transaction surveillance to activity that is already fully visible to the CFTC, the IRS, and now Illinois tax authorities. Participants who value financial privacy have no equivalent of a privacy-preserving protocol within CFTC-regulated event contract markets.

The broader regulatory trajectory matters here. As prediction markets grow and states move to tax them, the compliance infrastructure around these platforms will expand: more identity verification, more transaction reporting, and more data sharing between federal and state agencies. This is the same dynamic that has driven privacy-conscious users toward Monero (XMR) and similar tools in other financial contexts. The Illinois case is an early signal that prediction markets, once a relatively lightly regulated corner of financial activity, are entering the same compliance-heavy environment that now governs sports betting, securities trading, and traditional banking. Readers interested in the intersection of financial privacy and regulatory expansion can explore how Monero’s privacy architecture differs from transparent blockchain systems and why that distinction becomes more relevant as financial surveillance expands.

Key Takeaways

• Illinois Senate Bill 3019 taxes prediction market transactions at 1.75% for the first five million trades and 3.5% for all trades beyond that threshold, creating the first state-level transaction tax on CFTC-regulated event contracts in the U.S. [1]
• Kalshi, the leading CFTC-regulated prediction market exchange, has joined the Commodity Futures Trading Commission in filing a federal lawsuit against Illinois over Senate Bill 3019, with the case currently pending [1]
• The Sports Betting Alliance, representing DraftKings and FanDuel, opposes the sports betting tax increases in the same bill, arguing higher taxes drive bettors to unregulated offshore platforms [1]
• Illinois raised sports betting taxes in May 2025; by May 2026, bets placed in the state had fallen 21% year-over-year and the total sports betting handle had dropped 10.2% [1]
• The CFTC’s direct participation in the lawsuit against Illinois is unusual and signals the agency views the state tax as a challenge to its exclusive federal jurisdiction over commodity futures markets
• The prediction market tax is structured as a per-transaction levy, not a percentage of operator revenue, meaning it applies regardless of platform profitability and scales directly with user activity
• If the federal preemption argument succeeds in court, the ruling could block any U.S. state from imposing similar transaction taxes on CFTC-regulated prediction market platforms

Frequently Asked Questions

The Bottom Line

Illinois is attempting to extend its aggressive gambling tax strategy into prediction markets, a federally regulated sector that operates under an entirely different legal framework than sports betting. Senate Bill 3019’s two-tier transaction tax structure, reaching 3.5% on high-volume platforms, has triggered a direct legal confrontation with the CFTC, a federal agency that rarely litigates against state governments. The outcome of that lawsuit will determine not just Illinois’s revenue ambitions but whether any U.S. state can tax CFTC-regulated event contract trading at all.

The empirical record from Illinois’s own sports betting market offers a clear warning. The 21% drop in bets placed and the 10.2% decline in the sports betting handle following the May 2025 tax increase demonstrate that punitive transaction taxes shrink regulated markets rather than simply extracting more revenue from them. Applying the same logic to prediction markets, which are still in an early growth phase nationally, risks stunting a legitimate financial sector before it reaches maturity in Illinois.

For anyone tracking the intersection of financial regulation, privacy, and decentralized alternatives, the Illinois case is a textbook example of how state-level tax policy can reshape the boundaries of regulated financial activity and accelerate interest in privacy-preserving alternatives. The Kalshi and CFTC lawsuit may ultimately protect prediction markets from state overreach, but the legislative intent in Springfield is clear: every new financial transaction category is a potential tax base, and Illinois intends to collect.
