How has sports gambling changed in the United States since the 2018 Supreme Court decision?

Since the Supreme Court struck down the federal ban on sports gambling in 2018, the industry has expanded dramatically across most U.S. states. Sports wagering has surged from $4.9 billion in 2017 to over $121 billion in 2023, with 94% of these bets placed through mobile apps or online platforms. This rapid growth has coincided with concerning trends in gambling addiction. A recent study published in JAMA Internal Medicine reported a 23% increase in people searching online for "am I addicted to gambling?" This suggests that as sports betting becomes more accessible, particularly through digital channels, there's a parallel rise in potential gambling addiction concerns.
