Surge in Gambling Disorder Diagnoses Linked to Legal Sports Betting

Rise in Diagnosed Gambling Disorders
Electronic health records show a 60 % rise in gambling-disorder diagnoses in states that legalized sports betting after the 2018 Supreme Court decision, climbing from 3.0 to 4.8 cases per 100,000 adults. In the 11 states that kept betting illegal, diagnoses fell about 30 %.
Legalization Context and Study Scope
The 2018 ruling lifted the federal ban on sports wagering, leading many states to launch online sportsbooks and later prediction-market platforms that accept wagers regardless of local law. Epic Research examined records of over 197 million adults from Jan 2018 to Mar 2026 via its parent’s electronic-health system.
Quantitative Findings
Key metrics: legal-betting states saw a 60 % rise (3.0 -> 4.8 per 100,000); non-legal states fell ~30 %; highest overall rate among adults 30-49; steepest increase among men 18-29.
Official Industry Response
The American Gaming Association said the rise likely reflects increased screening and awareness, not a true surge in addiction, and cited its $500 million annual investment in education, research and support. Epic Research added the trends “cannot be attributed to any single legal event,” noting broader health-care shifts.
Public Health Critique
Rutgers social-work professor Mark van der Maas warned that expanding access “increases problems.” Harry Levant of the Public Health Advocacy Institute called the evidence “extremely important” and warned that online gambling’s “inherently dangerous nature” exposes younger, vulnerable users to a highly addictive product.
Clinical Observations
Steven Heim, outpatient supervisor at New Hope Integrated Behavioral Health Care in New Jersey, reported “an increase in referrals and diagnoses.” Rachel Volberg, a gambling researcher, said only 3-10 % of those with disorder seek treatment. Dr. Anthony Comerford likened brain impact of gambling disorder to that of heroin or other psychoactive drugs.
Divergent Interpretations and Gaps
Epic researchers attribute part of the increase to telehealth expansion and coding changes, while critics argue that broader access to online sportsbooks and prediction markets is the primary cause. Both acknowledge that many cases remain undiagnosed, leaving the true prevalence uncertain.
Verbatim Quotes
- “You increase access, you increase problems,” — Mark van der Maas, Rutgers University
- “This is extremely important evidence that speaks to not only the impact of legalization — but the inherently dangerous nature of how online gambling is fundamentally different than anything we’ve seen before,” — Harry Levant, Public Health Advocacy Institute
- “While problem gambling is a serious condition for those impacted, this study does not indicate an increasing rate of addiction,” — American Gaming Association
- “It’s going to take a few years for us to recognize these harms, because it doesn’t show up on day one,” — Matthew Platkin, former New Jersey Attorney General
Anticipated Developments
Former New Jersey Attorney General Matthew Platkin predicts a spike in gambling-related harms within three years as online betting normalizes. New prediction-market platforms, which often allow wagers at age 18 and operate with limited oversight, could further narrow the gap between legal and illegal jurisdictions, extending the public-health impact.
