FanDuel Switched Its Illinois Surcharge Back On Five Days After a Federal Judge Told Illinois It Probably Cannot License Kalshi. The Tax Survived. The Licence Did Not

A FanDuel customer in Illinois who put $5 on the Rays tonight paid $5.50. The 50-cent per-bet fee the company suspended in April is back as of Wednesday, on every qualifying wager, with three ways out: make the parlay at least $10, make the straight bet at least $25, or use a bonus bet.

Those exemptions are the whole design. FanDuel is not charging its customers 50 cents. It is charging the customers it does not want 50 cents, and telling everyone else exactly how to avoid it. A $25 straight bet at even money needs a 50.5 per cent win rate to break even once the fee is in. A $1 bet at the same price needs 66.7 per cent. Nobody wins 66.7 per cent of anything, which is the point: the fee is a tax on the account that fires twelve $2 bets on a Tuesday, and that account is the one Illinois charges FanDuel the most to service.

Why the fee exists, and why the pause was always temporary

Illinois in 2025 became the first American jurisdiction to tax sports betting per transaction rather than purely on revenue: 25 cents on each of an operator's first 20 million wagers in a fiscal year, 50 cents on every wager after that. For FanDuel and DraftKings, who clear 20 million tickets in Illinois well before the fiscal year is out, the marginal ticket costs 50 cents regardless of whether it is a $2 ticket or a $2,000 one. That is a tax on count, and the two books whose growth story is built on micro-betting and same-game parlays had built a business on count.

Flutter's response in June 2025 was to pass it straight through. DraftKings signalled within days that it would do the same. Then, in April of this year, FanDuel suspended the surcharge "until at least June 19" — the scheduled date of Game 7 of the NBA Finals. That series went five. The suspension outlasted its stated reason by nearly four months and ended this week, two days into the Division Series and three weeks before an NBA season starts.

The timing is not subtle. The fee comes back at the exact moment Illinois handle climbs.

The ruling that changed the arithmetic

On the Friday before it came back, U.S. District Judge Martha Pacold handed down a preliminary injunction in the consolidated Illinois cases brought by Kalshi and Coinbase, with the CFTC on their side. She enjoined Illinois from applying its sports-wagering licence regime and the attached criminal provision to prediction-market contracts — the 21-and-over requirement, the physical-presence requirement, the restrictions on which events may be listed. "Many of the financial instruments at issue are likely swaps as defined by the Commodity Exchange Act," she wrote, "they just happen to be swaps that people find entertaining and fun."

She did not enjoin the tax. Illinois had written a 1.75 per cent levy on prediction-market transaction fees, and Pacold left it alone, with a line that reads like an invitation: taking a cut of Kalshi's and Coinbase's profits, "without more, might not pose the same conflict as regulating an entire market." The parties have until October 29 to submit a proposed injunction tracking her opinion.

Put the two halves of the Illinois regime next to each other and you get something nobody designed on purpose.

A licensed sportsbook in Illinois pays revenue tax on a sliding scale to 40 per cent, plus 25 or 50 cents a ticket, plus licensing, plus the compliance cost of age and geolocation verification — and it may legally take the bet. A CFTC-registered exchange offering an economically similar contract pays 1.75 per cent of its transaction fees, is enjoined from having to verify age or location under state law, and faces no state licence at all. The state kept the smaller of its two revenue streams from the newcomer and lost every rule that made the incumbent expensive to be.

The counterargument, which is better than the industry's version of it

The American Gaming Association line is that this is a loophole and the remedy is to close it. That framing is weaker than it sounds, and the stronger version of the other side is worth stating properly.

It goes: Kalshi's product genuinely is different in market structure. It is an exchange, not a book. It does not set a line and take the other side; it matches a buyer against a seller and charges both. It cannot limit a winning customer, because it has no position to protect — the thing American sportsbook customers complain about more than any other. The reason it is cheap to operate is not regulatory arbitrage, it is that it carries no risk inventory. Taxing its fee revenue at 1.75 per cent is therefore not a sweetheart deal; it is the only coherent way to tax a venue that never books a wager.

That argument is right about the mechanics and wrong about the consequence. Illinois' per-wager tax exists because the legislature decided high-frequency, low-stake betting imposes costs the state wants paid for. Whether the venue holds the risk has nothing to do with whether a bettor in Peoria is firing forty microbets at 1 a.m. Pacold's injunction is good law and the result is still that the state's public-health instrument now applies to one of two competing venues, and the other one gets to advertise that it does not charge the fee.

Watch what FanDuel does about that. The surcharge is a visible, itemised 50 cents on a receipt, sitting next to a competitor whose pitch is that it has no such line item. The exemptions tell you FanDuel already knows: steer the customer to a $25 straight bet or a $10 parlay and the fee vanishes, which is a polite way of saying please stop being the kind of customer Illinois taxes us for.

What would falsify this

If DraftKings holds its own Illinois surcharge steady and FanDuel's Illinois handle does not visibly soften relative to it over the next two monthly Illinois Gaming Board reports, then the fee is a nuisance and not a wedge, and prediction markets are not yet capturing the bettors it pushes away. We will look. The figure to watch is not handle but ticket count, and Illinois is one of the few states that publishes enough to tell the difference.

The other thing to watch is Springfield. Pacold told Illinois its licence regime probably cannot reach Kalshi and all but told it the tax probably can. A legislature reading that opinion and acting rationally raises the 1.75 per cent — and the first state that tries will produce the next lawsuit, because Kalshi's position has never been that it objects only to licensing.
