$59 Billion Wagered in Illinois Alone Since Legalization — The Numbers That Put Sports Betting’s Scale in Perspective

Fifty-nine billion dollars. That’s how much has been wagered on sports betting in the state of Illinois alone since the Prairie State legalized and launched the product in 2020. The figure, surfaced this week in an ABC News investigation drawing on data from the Illinois Gaming Board and the American Gaming Association, is the kind of number that stops you mid-scroll. It’s not a national total. It’s not a five-year projection. It’s one Midwestern state, six years of legal sports betting, nearly sixty billion dollars out of American pockets and into the handle.

What $59 Billion Actually Means

First, a vocabulary note that every bettor should have internalized by now: handle and revenue are not the same thing. Handle is the total amount wagered — every dollar that flows through a sportsbook, including money that’s returned to winning bettors. Revenue — or adjusted gross revenue (AGR) — is what sportsbooks keep after paying out wins. The two numbers look dramatically different.

Illinois’s $59 billion handle has generated approximately $5.1 billion in revenue and profits for sportsbooks since 2020, with $1.1 billion going to the state in tax receipts. That’s a hold rate of roughly 8.6 percent across the full period — meaning for every $100 wagered, bettors got back about $91.40 on average. The house edge is real, it compounds, and over six years and $59 billion in wagering volume, the math tells the story clearly.

For context on scale: Illinois handled $15.5 billion in sports betting in 2025 alone — up from $14 billion in 2024 and $11.6 billion in 2023. The market hasn’t plateaued. It’s still growing, even with a new per-wager tax implemented in July 2025 that pushed some volume down while hold percentages crept up. The money is still moving; the structure of how it moves is just changing.

How Illinois Stacks Up Nationally

Illinois is one of the largest sports betting markets in the country, behind New York and New Jersey in overall handle but comparable in scope. The AGA has reported that national sports betting revenue hit approximately $16.6 billion in 2025 — up from $921 million in 2019, the first full year most states began permitting it. That’s an 18-fold increase in six years, representing one of the fastest-growing consumer industries in American economic history.

New York, which launched mobile betting in January 2022, routinely handles $1.5 to $2 billion per month and has surpassed $30 billion in cumulative handle. New Jersey, the state whose 2018 Supreme Court victory opened the door for national legalization, has been a top-five market since day one. But Illinois — with Chicago, the third-largest city in the U.S., and a massive college sports culture — has established itself as a genuine pillar of the national betting economy.

March Madness, currently underway, will push those numbers higher. The NCAA Tournament generates some of the largest single-month handles of any sports calendar period, with the AGA estimating tens of millions of Americans placing brackets and bets each year. 2026’s tournament figures aren’t yet finalized, but every indicator suggests records will be broken again.

The Scrutiny These Numbers Invite

The ABC News investigation wasn’t a celebration of the betting industry’s growth. It was framed around a question that’s becoming impossible to ignore: what is this scale of gambling doing to the population being exposed to it?

The concerns are specific. Researchers and addiction treatment professionals are reporting a measurable increase in problem gambling cases, with a particular concentration among younger users — people who grew up doing everything on their phones and for whom the mental friction between seeing a betting ad and placing a wager is essentially zero. Illinois requires users to be 21, but underage workarounds exist, and the digital-native generation is both the betting industry’s target market and its most vulnerable one.

In Illinois, the per-wager tax implemented in July 2025 was partly a regulatory response to these concerns — an attempt to slow volume growth by increasing operator costs, which were then passed to bettors through surcharges. The volume of bets placed in the state dropped by roughly 20% in January 2026 compared to the same month the prior year, even as handle barely declined. Bettors are placing fewer, larger wagers — a behavioral shift that may reflect the surcharges or may reflect maturing user habits.

Legislative pushback is real in multiple states. Advertising restrictions that limit how and where sportsbooks can market to consumers have passed or are being debated in several jurisdictions. Illinois’s progressive tax rate — which scales above 15% for the largest operators — is a model others are watching.

How Bettors Should Think About This

These numbers matter for bettors not as moral indictment but as context. The sports betting industry is large, profitable, growing, and under increasing political and regulatory pressure. That combination historically produces volatility: new taxes, tightening advertising rules, product restrictions, and in some cases, the exit of operators from markets that become unprofitable to serve.

The Illinois experience already previewed this. When the per-wager tax launched, FanDuel and DraftKings both implemented customer-facing surcharges — small fees added to each bet that effectively transferred the tax cost to bettors. The industry framed these as necessary adjustments; regulators and consumer advocates called them hidden fees. The argument isn’t over.

For the average bettor, the $59 billion figure is a useful anchor point: this industry is too big to go anywhere. Legal sports betting is a permanent feature of American consumer life. But its terms — who captures how much of the value, who bears what share of the social costs — are still being negotiated. Every major piece of data that gets published, every investigation, every state legislative session is part of that negotiation. Bettors have a stake in how it turns out.

Fifty-nine billion dollars in one state. Let that number be your reference point the next time someone tells you the sports betting industry is still finding its footing.
