While the debate around UK gambling reform has focused heavily on tighter rules for licensed operators, a new warning from the Betting and Gaming Council shifts attention elsewhere. The bigger risk, it argues, may be the growing visibility of illegal gambling operators, whose advertising spend is climbing fast enough to challenge the licensed market itself.
Analysis cited by the BGC, drawing on data from WARC, suggests unregulated operators are rapidly gaining ground in UK gambling advertising. If current trends hold, illegal operators could account for a majority share of gambling ad spend by 2028, a development that raises difficult questions about channelisation, enforcement, and whether current reforms are targeting the right problem.
Licensed Ad Spend Is Falling
The figures point to a two-speed market. Total UK gambling advertising spend is projected to reach £1.9 billion by October 2026. Within that, licensed iGaming operators are expected to reduce spend by 9.2%, falling to roughly £1.1 billion.
At the same time, unregulated operators are projected to increase advertising expenditure by 32%. That shift marks a sharp change from previous years, when licensed firms represented more than 80% of sector ad spend. Today, that share has dropped to just over half. On current projections, illegal operators could overtake regulated firms within two years.
The concern is not simply market share. It is that growing ad visibility from unlicensed brands may undermine the UK’s regulated framework by drawing players toward operators that sit outside consumer safeguards.
Why This Matters in the Wider Gambling Reform Debate
The timing is significant. The data lands as policymakers continue weighing financial risk checks, higher gambling taxes, and broader advertising restrictions.
Industry groups argue there is a risk of unintended consequences. If tighter rules weaken the competitiveness of licensed operators while illegal firms continue expanding through search, social media, and sponsorship, channelisation could come under greater strain.
That is the core warning from the BGC. The question, it argues, is not whether gambling advertising exists but who is paying for it and under what rules. The trade body has urged policymakers to focus more aggressively on black market enforcement rather than placing additional pressure on operators already subject to strict compliance standards.
Sponsorship And Digital Channels Are Driving the Shift
Part of what makes the trend harder to ignore is where the growth is happening. WARC’s analysis suggests illegal operators are increasing spend across digital acquisition channels, particularly search and social platforms.
Sponsorship is another pressure point. Unregulated firms are projected to account for more than half of gambling sponsorship ad spend next year, adding another layer to concerns about visibility and consumer exposure. That matters in legal and policy terms because enforcement has traditionally focused more on licensed operator conduct than on the cross-border marketing tactics of offshore firms.
