Sports betting is legal, everywhere, all the time, on a device in your pocket. Gambling disorder diagnoses are up 61% in states that allow it. As football season kicks off, here’s what the data actually shows.
Americans bet $166 billion on sports in 2025 alone. Since legalization began rolling out state by state in 2018, the total wagered nationally has passed $600 billion. Those aren’t casino numbers from Las Vegas, they’re numbers from an app most people have open on their phone during the game, placing bets between plays instead of just watching them.
Is this actually creating more gambling problems, or are people just betting more without getting hurt by it?
The data says it’s creating real problems, and the comparison is about as clean as social science gets. Gambling disorder diagnoses have risen 61% in states that legalized sports betting. In the states that haven’t, diagnoses fell 29% over the same period, dropping about 30% from 2018 through early 2026. Same country, same time period, different legal environment, dramatically different outcome. That’s not a coincidence, that’s a controlled comparison playing out at a national scale.
Who’s actually most at risk here?
Young men, overwhelmingly. Nearly 40% of men gamble online daily, compared to 20% of women, and 2% of bettors are gambling more than ten hours a day, which is no longer a hobby by any reasonable definition. The rate of gambling problems among people who specifically bet on sports is at least double the rate among gamblers generally, and among online sports bettors specifically, gambling disorder runs as high as 16%. As many as 32.25 million adults are considered at risk each year. Of those, roughly 2.5 million meet the clinical criteria for a severe gambling problem, with another 5 to 8 million experiencing mild to moderate issues.
Legalized sports gambling has been found to increase the risk that a household goes bankrupt by 25% to 30%.

Why is this so much more dangerous than gambling used to be?
Access and speed. A casino requires driving somewhere, walking in, and physically placing a bet, all of which naturally create friction and a moment to reconsider. A betting app requires none of that. It’s open during the game, it’s designed by the same behavioral scientists who build the rest of the addictive apps on your phone, and it turns every single play, not just the final score, into a new opportunity to bet. In-game “micro-betting,” wagering on whether the next play is a run or a pass, has made the entire three-hour broadcast into a continuous betting surface instead of one bet placed before kickoff.
Isn’t the NFL just as invested in this as the sportsbooks?
Functionally, yes. The NFL is the single most-bet-on league in the country, and broadcasts now carry sportsbook advertising as a normal, expected part of the commercial break, including during the Super Bowl. That’s a meaningful shift from a league that spent decades publicly distancing itself from gambling over fears about game integrity. The money changed the calculation, and now the same broadcasts that carry the games carry the ads inviting you to bet on them, often within the same commercial pod.
Is anything actually being done about this?
Some. A handful of states are experimenting with self-exclusion programs, stricter advertising rules, and spending limits tied to a user’s account, but adoption is uneven and, so far, largely voluntary rather than required. The core tension hasn’t been resolved: states collect meaningful tax revenue from legal sports betting, which creates a real incentive not to restrict it too aggressively, even as the same states are watching gambling disorder rates climb inside their own borders.
