Open Banking Data Reveals Patterns in Unlicensed Gambling Activity

The UK Gambling Commission published its initial open banking analysis in November 2026, examining payment transactions directed toward unlicensed gambling platforms, and the dataset draws directly from consumer banking records rather than self-reported surveys. This approach marks a shift because transaction-level information provides granular visibility into how funds move between accounts, allowing analysts to track repeat interactions with operators outside the regulated framework. Observers note that the timing coincides with broader discussions on potential tax adjustments for the gambling sector, yet the report itself focuses strictly on observed payment behaviors. Data from the study indicates that repeat users of unlicensed sites maintained their activity with licensed operators in most cases, showing no major drop-off in regulated betting volumes. Specifically, figures reveal that 91 percent of those engaging repeatedly with illegal operators continued placing bets through authorized channels without substantial reductions, suggesting the two forms of activity often run in parallel instead of one displacing the other. Researchers tracked these patterns across multiple months of transaction histories, confirming the overlap through direct payment trails. Problem gambling indicators appeared elevated among individuals who transacted with unlicensed sites, according to the aggregated scoring metrics applied to the dataset. The analysis cross-referenced payment frequency and amounts against established problem gambling assessment tools, producing higher average scores for the unlicensed cohort compared with those who stayed within licensed environments. This correlation emerges from the banking data alone, without reliance on questionnaire responses that might introduce reporting bias.

Methodology Behind the Transaction Analysis

Open banking protocols enabled the Commission to access anonymized payment flows, mapping transfers to known unlicensed domains while preserving user privacy through aggregated reporting. Analysts identified unlicensed operators by cross-checking domain lists against regulatory records, then followed the movement of funds over defined periods. The resulting dataset covered thousands of accounts, providing a sample large enough to detect consistent behavioral clusters without identifying individuals.

Unlike traditional surveys that depend on participant recall, this method captures actual transaction timestamps, amounts, and destinations, which reduces certain types of measurement error. Experts involved in the project highlighted that the technique allows for longitudinal tracking, revealing whether activity with unlicensed sites occurs alongside or instead of licensed play. The report explicitly states that supplementation, rather than substitution, characterizes the dominant pattern observed.

Context Within Ongoing Regulatory Discussions

The release occurs while policymakers examine potential changes to gambling taxation, and the findings supply transaction-based evidence that could inform those deliberations. Because the study isolates payment behavior without interpreting motives, it supplies raw observations for others to consider alongside fiscal proposals. Those reviewing the material note that the 91 percent overlap figure underscores the continued role of licensed operators even among users who also access unregulated platforms.

Problem gambling score differentials receive particular attention in the document, with the data showing statistically significant elevation for the unlicensed group. The Commission presents these scores as derived from validated instruments applied to spending patterns, not as diagnostic conclusions for any single account. Such presentation keeps the focus on population-level trends rather than individual cases.

Implications Drawn from Payment Patterns

Because illegal activity supplements rather than replaces licensed play, the report suggests that enforcement efforts targeting unlicensed operators may need to account for persistent dual usage. Transaction records demonstrate that many accounts continue routing funds to both categories, implying that blocking one channel alone does not automatically redirect all activity. Regulators receive this information at a moment when debates about tax policy continue, yet the study refrains from recommending specific fiscal measures.

Further examination of the dataset reveals seasonal fluctuations in payment volumes, though the core 91 percent overlap statistic holds across the observed periods. Analysts segmented the data by user tenure with unlicensed sites, confirming that longer-term repeat users still exhibit the same pattern of maintained licensed activity. This consistency strengthens the observation that the two markets coexist for a substantial portion of the tracked cohort.

Conclusion

The UK Gambling Commission's open banking study supplies transaction-derived evidence on unlicensed gambling participation, documenting both the 91 percent continuation rate with licensed operators and elevated problem gambling scores among those using unregulated sites. By relying on payment records collected in November 2026, the analysis offers an alternative to survey methods and highlights supplementation as the prevailing relationship between the two forms of activity. Stakeholders now have additional data points to review as discussions on taxation and market oversight proceed.
