Americans' financial health is deteriorating as sports betting surges across the country. A New York Federal Reserve report found that in states where sports betting is legal, credit delinquency rates rose about 0.3% overall, with gamblers who started betting after legalization seeing credit delinquencies spike by more than 10%. The study examined data from over 30 U.S. states where the practice is legal.

This trend follows a 2018 Supreme Court decision that allowed states to legalize sports betting, transforming it into a multi-billion dollar industry. Americans are projected to legally wager $3.3 billion on March Madness alone this year, a 50% increase over three years. Since the pandemic, bettors have more than doubled their quarterly spending from under $500 in December 2019 to over $1,000 by June 2021, driven by mobile apps and aggressive marketing campaigns.

Research from UCLA's Brett Hollenbeck found even starker results, with average credit scores dropping 0.8 points in states that legalized sports betting. States allowing online betting saw a 10% increase in bankruptcy likelihood and 8% increase in debt collection amounts. Young people under 40 showed the sharpest credit deterioration. Addiction experts warn that while most users won't develop problems, those predisposed to addiction face significant financial risks as online betting becomes increasingly accessible.
