The number of states with operational sportsbooks increased from 1 during 2017 to 38 during 2024. Total sports wagers increased from $4.9 billion during 2017 to $121.1 billion
during 2023, with 94% of wagers during 2023 being placed online. There were 23% (95% CI, 15%-30%) more searches nationally for gambling addiction help-seeking after Murphy v
National Collegiate Athletic Association. Massachusetts (47%; 95% CI, 21%-79%), New Jersey (34%; 95% CI, 21%-45%), New York (37%; 95% CI, 26%-50%), and Pennsylvania (50%; 95%
CI, 35%-66%) each had more searches than expected after the opening of any sportsbooks in their state. Additional analyses suggest the opening of online, vs retail, sportsbooks
corresponded with a larger increase in searches. Read the entire JAMA investigation here.
