Europe's Black Market Online Gambling Reaches €12B as Regulatory Friction Fuels Offshore Growth

Europe's underground online gambling market has reached a critical inflection point. New research commissioned by Euromat, the trade body representing Europe's land-based gaming sector, estimates that illegal operators generated €12 billion ($14.1 billion) in net revenue during 2025. The figure represents a staggering threefold expansion since 2019, when the black market was substantially smaller and less visible to regulators and the licensed industry alike.

The study, conducted by advisory firm Regulus Partners and web traffic specialist Helios across 28 European markets, employed a methodology combining digital traffic analysis, marketing data, and macroeconomic indicators to size the underground sector. The findings suggest that offshore gambling now captures approximately one-quarter of all online gambling activity in Europe, a proportion that would have seemed implausible just five years ago.

The research identifies three primary drivers behind this explosive growth. First, restrictive regulatory frameworks and state monopolies in certain markets limit consumer choice, pushing players toward offshore alternatives. Second, interventionist consumer protection policies such as affordability checks and deposit limits, while well-intentioned, create friction that incentivizes players to seek unregulated platforms. Third, and increasingly significant, is the rise of cryptocurrency gambling. Few regulated European markets currently offer legal pathways for crypto wagering, leaving that product category entirely to unlicensed operators who can offer faster transactions and greater anonymity.

Filip Jelavic, managing director of Helios, emphasized that this market did not emerge organically. 'Black markets don't happen by accident but instead are the result of government policies that create consumer friction,' he noted. The research also identified that several large offshore operators have achieved sufficient scale to establish recognizable brands and meaningful market share within their target jurisdictions.

The findings arrive amid rising alarm from regulators and industry bodies across Europe. The Betting and Gaming Council recently warned that black market Premier League betting alone could reach GBP 1 billion ($1.36 billion) in wagers next season. Meanwhile, Nederlandse Loterij, the state lottery operator in the Netherlands, has pursued legal action against three unlicensed operators targeting Dutch players in recent months. These enforcement actions reflect growing recognition that the offshore threat has shifted from a manageable nuisance to a systemic challenge.

Euromat President Jason Frost framed the research as a catalyst for policy engagement, arguing that offshore operators gain unfair competitive advantages by avoiding taxes and regulatory compliance costs. The association plans to use the study's findings as the foundation for a broader engagement program with European governments and law enforcement agencies, positioning itself as a key stakeholder in the policy conversation around black market containment.

The data underscores a fundamental regulatory paradox: consumer protection measures designed to reduce gambling harm can paradoxically push engaged, higher-value customers into unregulated environments where protections are minimal or nonexistent. Policymakers now face the challenge of calibrating regulation to maximize consumer safety while minimizing the appeal of offshore alternatives.
