UKGC Study Challenges Substitution Narrative, Finding Illegal Gambling Complements Licensed Activity
The UK Gambling Commission (UKGC) has published empirical research using Open Banking financial transaction data that directly challenges a key industry argument regarding black-market dynamics. The study indicates that consumer engagement with unlicensed operators functions primarily as a supplement to rather than a direct replacement for activity with licensed British gambling businesses.
Analyzing an anonymized dataset linking banking records with survey responses, the regulator identified 3,426 distinct transactions involving suspected illegal operators across 179 individuals. Crucially, 91% of consumers with repeated unlicensed transactions simultaneously maintained active play with licensed operators. Furthermore, researchers detected no substantial drop in licensed gambling volume following a player’s initial transaction with an illegal site, suggesting that unlicensed play exists alongside regulated activity rather than replacing it.
Elevated Harms and Credit Usage in the Unlicensed Sector
The transaction analysis revealed a strong correlation between illegal market participation and severe gambling harm. Of the 146 individuals in the sample with available Problem Gambling Severity Index (PGSI) scores, 45% scored 8 or higher the threshold indicating problem gambling. In contrast, only 6% of consumers transacting exclusively with licensed operators within the same dataset reached this severity level.
The report also uncovered ongoing circumvention of national regulatory bans. Researchers identified 138 credit card transactions (representing 4% of total detected illegal payments) across 15 individuals. Credit card gambling has been strictly prohibited across all regulated UK betting and gaming channels since April 2020.
Methodological Scope and Enforcement Strategy
The Gambling Commission noted several methodological limitations, clarifying that the dataset is not nationally representative and cannot be used to estimate the overall absolute size of the black market. Furthermore, alternative payment channels such as cryptocurrency or masked merchant descriptors were not captured. Nevertheless, postdoctoral data scientist Steven Murphy characterized the study as a "powerful proof of concept" for utilizing financial transaction data to track unlicensed gambling behavior and strengthen multi-agency enforcement strategies.
