UK Gambling Commission Releases Initial Open Banking Analysis of Unlicensed Gambling Payments

The UK Gambling Commission published its first open banking study in November 2026 that examines payment data tied to black market gambling sites, and the findings center on how repeated transactions to unlicensed operators connect with activity on regulated platforms. Researchers analyzed banking records from individuals who showed multiple payments to illegal operators, and the data revealed that 91 percent of those same individuals also placed bets with licensed operators during the same period. This pattern suggests that unlicensed gambling functions as a supplement to legal betting rather than a complete replacement for it, according to the commission's payment analysis.

Study Background and Scope

Experts at the commission developed this open banking approach to track financial flows that bypass licensed channels, and the project drew on anonymized transaction details to identify patterns without accessing personal identifiers. The study focused on consumers who had triggered repeated detections through their payment activity, which allowed analysts to separate one-time incidents from ongoing engagement with unlicensed sites. Observers note that this marks the first time the regulator has applied open banking tools at this scale to map the black market, and the methodology relied on collaboration with financial institutions to flag suspicious merchant categories associated with illegal gambling.

Core Findings on Consumer Behavior

Data from the analysis shows that most people engaging with unlicensed operators maintain accounts and activity on licensed platforms as well, which indicates that illegal sites capture a portion of spending rather than diverting all funds away from regulated markets. Among the cohort with repeated illegal payments, the overlap with licensed gambling reached 91 percent, and this figure held steady across different age groups and regions examined in the dataset. Those who've studied the results point out that the pattern challenges assumptions about total substitution, since participants continued using legal operators for the majority of their activity while occasionally routing funds to unlicensed sites.

Links to Problem Gambling Indicators

The same payment records were cross-referenced with consumer surveys that measured problem gambling scores, and the commission found significantly higher harm levels among individuals who used unlicensed operators compared with those who stayed within licensed environments. Participants who showed repeated transactions to illegal sites recorded elevated scores on standard problem gambling scales, and the data indicated increased reports of financial distress and chasing losses. Researchers discovered that these elevated harm markers appeared consistently in the unlicensed cohort, which suggests that access to unregulated platforms correlates with greater risk exposure even when users also bet legally elsewhere.

What's interesting is how the study integrated Phase 3 Consumer Voice research completed in October 2026 to add qualitative context to the payment figures, and this combination allowed the commission to connect raw transaction data with self-reported experiences of harm. The findings reveal that people who mixed licensed and unlicensed gambling reported more frequent attempts to recover losses and higher overall spend relative to income than those who avoided illegal sites entirely.

Regulatory Context in Late 2026

Commission officials released the report amid ongoing efforts to strengthen enforcement against black market operators, and the open banking data provides new evidence that can support targeted interventions without relying solely on consumer complaints. The study does not estimate the total size of the illegal market, yet it supplies granular insight into the behavior of a specific high-risk group that regulators can now monitor more closely through continued data sharing with banks. Analysts have observed that the 91 percent overlap figure may influence future policy discussions around payment blocking and consumer education campaigns that highlight the risks tied to unlicensed platforms.

Implications for Licensed Operators

Licensed gambling companies receive indirect signals from the research because the data shows that their customer base overlaps substantially with users of illegal sites, which means responsible gambling tools already in place could reach many of the same individuals. The commission's analysis does not assign blame to licensed operators for the behavior of their shared customers, but it does underscore the need for continued collaboration between regulators and the industry to address harm wherever it occurs. Figures from the study indicate that problem gambling scores rise when unlicensed activity enters the picture, so operators may examine ways to identify at-risk patterns earlier through their own transaction monitoring systems.

Conclusion

The UK Gambling Commission's initial open banking study supplies concrete payment evidence that most repeat users of unlicensed gambling sites also remain active on licensed platforms, and it ties that activity to measurably higher levels of gambling-related harm. By focusing on transaction patterns rather than estimates alone, the report gives regulators and researchers a clearer view of how illegal and legal markets intersect for the same consumers. Continued application of these data tools could refine enforcement priorities and support more precise harm-reduction measures across the sector.
