Gambling Disorder Surges 60% Post-Legalization

Diagnoses for gambling disorder have risen by more than 60% since 2018 in U.S. states that have legalized sports betting. This significant increase is most pronounced among young men aged 18 to 29. The data comes from an analysis of electronic health records covering over 197 million adults from January 2018 to March 2026.

Conversely, the 11 states that did not legalize sports betting saw diagnoses fall by approximately 30% during the same period. Experts suggest that increased access to online betting platforms is a key factor, leading to greater harm. The findings align with concerns that wider availability of gambling, particularly online, contributes to addiction.

While the gaming industry states that increased diagnoses reflect greater awareness rather than a rise in addiction, some specialists report a clear influx of patients seeking help. A small fraction of individuals with gambling disorders are formally diagnosed, as symptoms are often hidden and treatment is not always sought through formal health care.

Gambling disorder is recognized as a mental health condition with similarities to substance abuse disorders, affecting the brain through similar mechanisms. Recent studies also link expanded online sports gambling to increased financial difficulties, such as bankruptcies and debt.
