Health Records Paint Clear Picture of Gambling Disorder Trends After Sports Betting Expansion

A recent commentary published in Sports Business Journal draws attention to findings from a comprehensive analysis of electronic health records covering more than 197 million U.S. adults, and the data tracks diagnoses of gambling disorder from the first quarter of 2018 through the first quarter of 2026. Researchers examined patterns across 39 states that introduced legal sports betting during that period, and rates climbed from 3.0 to 4.8 cases per 100,000 patients, which represents roughly a 61 percent increase. Observers note the absolute numbers stay relatively low, yet the proportional shift stands out when compared against states that kept sports betting off the books.
Study Scope and Methodology
The underlying research pulled from nationwide electronic health record systems, allowing analysts to follow trends in real time across a massive patient population, and this scale gives the results considerable weight when policymakers and health professionals review the impact of expanded betting access. Data collection began before most states had legalized the activity and continued well after legalization took hold in dozens of jurisdictions, which created a natural before-and-after comparison. The study period ends in early 2026, providing a multi-year window that captures both initial rollout effects and longer-term patterns.
Key Increases in Legalized States
In the 39 states where sports betting became legal after 2018, the rise in diagnosed cases appears consistent across multiple reporting periods, and experts attribute part of the movement to greater availability of betting platforms along with increased advertising visibility. The commentary highlights that expanded access and marketing campaigns coincided with the uptick, although researchers stop short of claiming direct causation and instead present the correlation as a signal worth monitoring. Those who have reviewed the full dataset point out that the increase occurred steadily rather than in isolated spikes, suggesting sustained influence from the new regulatory environment.
Demographic Patterns Emerge
Adults aged 18 to 29 showed the steepest proportional growth, with rates more than doubling over the study window, and the increase appeared disproportionately among males within that age group. Health records indicate younger adults interacted more frequently with newly legalized platforms, which aligns with broader usage data collected by operators and state regulators during the same years. Analysts examining the figures note that this demographic already faced higher baseline exposure to digital marketing, and the combination of mobile apps and targeted promotions may have contributed to the observed change in diagnosis rates.

Contrast With Non-Legalized States
Eleven states that did not legalize sports betting during the same timeframe recorded a decline in diagnoses, dropping from 3.1 to 2.2 cases per 100,000 patients for an approximate 29 percent reduction, and this downward movement stands in direct contrast to the trend observed where betting markets opened. The commentary presents the divergence as noteworthy because it offers a side-by-side view of similar populations operating under different regulatory conditions. Researchers continue to examine whether reduced advertising presence or limited platform access played roles in the lower rates recorded in those states.
Context Around Absolute Rates and Advertising
Although the percentage increase draws attention, the commentary emphasizes that raw prevalence remains low across the entire dataset, and public health officials have framed teh findings as a call for continued surveillance rather than an immediate crisis. Links between expanded access, advertising volume, and diagnosis patterns receive repeated mention, yet the piece also notes that many other factors, including changes in screening practices and patient willingness to seek care, could influence the numbers. Data from the same health records show that states with the earliest legalization dates tended to register earlier rises, which supports the timing connection drawn in the Sports Business Journal commentary.
Implications for Ongoing Monitoring
Public health researchers and state agencies have begun incorporating these electronic health record trends into regular reporting dashboards, and several jurisdictions now require operators to contribute data on responsible gambling measures as part of licensing renewals. The commentary suggests that future analyses will track whether the rate of increase slows as markets mature or whether additional variables such as deposit limits and self-exclusion tools alter the trajectory. Those reviewing the study results stress the value of maintaining consistent diagnostic criteria across states so comparisons remain reliable over time.
Conclusion
The Sports Business Journal commentary brings together a large-scale examination of electronic health records and presents a clear statistical contrast between states that legalized sports betting and those that did not, and the findings center on a 61 percent rise in one group alongside a 29 percent drop in the other. Demographic detail shows the sharpest movement among younger adults, particularly males, while absolute rates stay low across the board. Continued observation through 2026 and beyond will help clarify how access, advertising, and regulatory tools interact with these health indicators in the years ahead.
