Sports betting keeps growing across the US, yet Illinois shows cracks at the worst possible moment. New state data, combined with operator feedback, paints a clear picture of bettors pulling back right after new wager-based taxes kicked in.
The debate no longer sits around theory. The numbers now speak for themselves, and industry groups argue the legal market absorbs the damage.
Good to Know
Fresh figures from Illinois Gaming Board show October 2025 closing with 6.4 million fewer wagers compared to the same month a year earlier. September already showed a 5 million bet decline, making the trend harder to ignore.
According to Sports Betting Alliance, the pattern clashes with what happens elsewhere. Sports betting volume continues climbing in other states, fueled by football season and mobile engagement.
The group represents FanDuel, DraftKings, BetMGM, Fanatics Sportsbook, and bet365.
Industry voices argue the timing lines up too closely with the rollout of per-wager fees to dismiss.
Illinois lawmakers rolled out a 25-cent tax on every online wager in July. After sportsbooks cross 20 million bets, the rate doubles to 50 cents. Operators reacted fast.
Some introduced flat betting surcharges. Others raised minimum wager amounts. A few adjusted odds margins quietly. Each path leads to the same outcome: higher friction for everyday bettors.
The Sports Betting Alliance summed up the concern in a public statement:
“The IGB’s recent data illustrates more alarming evidence that tax hikes are creating a lose-lose situation for fans, where they’re either being forced to pay higher fees or left to abandon the legal sports betting market. This is a warning sign, and with Chicago city leaders lumping even higher taxes on fans, Illinois lawmakers are putting at risk the very sturdy regulated market they’ve built since legalization.”
Chicago added its own burden starting January 1. A 10.25 percent tax on sportsbook operators applies to wagers placed inside city limits. The policy triggered a lawsuit from the Sports Betting Alliance earlier in the month.
Operators now juggle state-level wager taxes, a progressive revenue tax structure, and local city charges inside one of the largest betting hubs in the Midwest.
The state already moved to a progressive tax system in 2024. Rates start at 20 percent and rise to 40 percent for sportsbooks generating more than $200 million in adjusted gross revenue. Combined with per-wager fees, Illinois ranks near the top for total sportsbook taxation.
Illinois still delivers massive betting handle. October posted a record $1.6 billion wagered, producing $135 million in adjusted gross revenue. The state collected more than $41 million in taxes for the month.
Yet handle alone masks deeper issues. Fewer bets signal fewer casual players and lighter engagement, according to industry analysts. September marked the first full month with sportsbooks actively offsetting wager taxes, and the year-over-year decline arrived immediately.
