Offshore Operators Capture Growing Slice of UK Gambling as Licensed Market Share Slips

Researchers at H2 Gambling Capital have documented a sharp rise in activity on illegal offshore platforms, which drew £16.6 billion away from UKGC-licensed operators during 2025, compared with £5 billion six years earlier, and the data forms part of a May 2026 update on unregulated casino, poker, and sports betting activity. The figures show teh legal sector's share of total wagers declining from 97 percent in 2019 to 92 percent last year, a shift that coincides with several regulatory and market pressures.

Key Drivers Behind the Movement

Higher tax rates, including the 40 percent Remote Gaming Duty, have increased operating costs for licensed firms while affordability checks have added verification steps for players. At the same time, unlicensed operators have expanded their reach through aggressive digital marketing and crypto-based payment options that avoid traditional banking oversight. Observers note these factors create a competitive environment where offshore sites can offer faster transactions and fewer restrictions, drawing customers who might otherwise stay within the regulated market.

Data from the study indicates the black market has grown steadily rather than in sudden spikes, suggesting sustained appeal among certain player segments. Those who track payment flows report that crypto channels allow offshore sites to process deposits and withdrawals with minimal friction, a feature that licensed operators cannot replicate under current rules.

Regulatory Response and Enforcement Actions

The UK Gambling Commission has continued to block more than 266,000 offshore URLs, a figure that reflects ongoing efforts to limit access to unlicensed sites. Commission staff also work directly with internet service providers and social media platforms to remove promotional content and restrict payment processing routes. These measures form part of a broader strategy that combines technical blocks with public awareness campaigns aimed at highlighting the risks of unregulated gambling.

Analysts point out that enforcement remains an ongoing process because new domains appear regularly and operators frequently change their online addresses to stay ahead of restrictions. Collaboration with technology companies has helped close some channels, yet the scale of the task continues to grow alongside the reported increase in offshore volume.

Impact on Licensed Operators and Player Behavior

Licensed operators have seen revenue pressure as a portion of their potential customer base migrates to offshore alternatives. The H2GC research shows this leakage has accelerated since 2019, coinciding with the introduction of stricter affordability protocols and the rise in duty rates. Some firms have responded by adjusting their marketing approaches and introducing new responsible-gambling tools, while others focus on improving user experience within the constraints of current regulations.

Player surveys referenced in the study suggest that convenience and perceived value drive many choices toward offshore sites. Crypto payments, lower effective costs, and fewer identity checks appear among the most cited reasons. Those who study betting patterns observe that once players establish accounts on unlicensed platforms, they often continue using them for extended periods.

Broader Market Context in 2026

The May 2026 update places these trends within a wider picture of regulatory tightening across the UK gambling sector. Licensed operators face continued compliance costs, while enforcement bodies allocate more resources to monitoring digital channels. The data indicates that the 8 percent share now held by the black market represents a meaningful departure from earlier years when legal operators captured nearly all activity.

Industry reports show that total gambling volumes have remained relatively stable, meaning the shift primarily reflects redistribution rather than overall growth or contraction. This redistribution carries implications for tax collection and consumer protection frameworks, both of which depend on activity occurring within the licensed system.

Conclusion

The H2GC findings illustrate a clear expansion of offshore gambling activity through 2025 and into the early months of 2026. With £16.6 billion now moving through unregulated channels and the legal market share standing at 92 percent, the numbers provide a measurable record of change. The UK Gambling Commission's ongoing blocks and platform partnerships continue to address access points, while the underlying drivers—tax levels, affordability requirements, and payment innovations—remain central to the current landscape. Further updates expected later in 2026 will show whether these patterns hold or begin to reverse under additional regulatory measures.
