5 Worrying Data Points About Sports Gambling

The legalization of sports betting in some U.S. states in 2018 led to an explosion of gambling — and problems came with it. (The Economist)

The data:

  • In states with legal online betting, 10% of bettors spent at least 10% of their income on gambling, with low-income individuals being the most affected, according to a 2024 study by Southern Methodist University, the University of Maryland and UC San Diego.

  • Spending just 1% of income on gambling correlates with poor health and financial outcomes, prior research has shown.

  • A study by UCLA and USC published in 2024 found that in states with legalized online betting, credit scores dropped by almost 1%, bankruptcy rates increased by 28%, and debts sent to collections rose by 8%.

  • Fewer than 5% of bettors withdrew more than they deposited, collectively earning over $100 million, while the top 3% of bettors accounted for nearly 50% of net revenue for sportsbooks, according to an SMU study of 700,000 online gamblers.

  • States with online casino gaming saw the largest increases in irresponsible gambling and calls to gambling help lines, according to the same SMU study.

The anecdotes: According to a report in The Athletic, since 2020, Gamblers Anonymous has seen a dramatic shift, with men in their 40s—once the youngest attendees—now becoming the most common age group at meetings, largely due to the rise of sports gambling.

A Gamblers Anonymous spokesperson:

Today, we are opening meetings all over, specifically geared for males between 20 and 40, and the other day I was in a meeting with a 17-year-old. And the week before, somebody was in a meeting with a 14-year-old. We are tracing this all back to the legalization of all this, and the ability to gamble with your phone in your hand.
