Euromat Study Reveals Europe's Illegal Online Gambling Market Hit €12 Billion in 2025

Researchers at Regulus Partners along with web traffic specialists at Helios conducted a detailed analysis across 28 European markets for Euromat, the European Gaming and Amusement Federation, and the resulting figures show the illegal online gambling sector generated €12 billion in net revenue during 2025, which equals roughly $14.1 billion at current exchange rates. This amount has tripled since 2019 while now accounting for about 25 percent of the entire European online gambling sector according to the commissioned report.

Data indicates illegal operators maintain an edge through fewer restrictions such as oversized bonuses, cryptocurrency payments that represent around 35 percent of their transactions, and direct targeting of players who have self-excluded from licensed platforms. Observers note these tactics allow unlicensed sites to draw significant volume away from regulated markets where stricter rules apply to player protection and payment processing.

Scope of the Research and Market Scale

The study examined activity in 28 separate European jurisdictions and combined traffic analysis with revenue modeling to arrive at its estimates. Figures reveal the illegal market's expansion has outpaced the legal sector in several regions since 2019, creating a parallel economy that operates outside standard tax and compliance frameworks. Those who analyzed the web traffic patterns found illegal platforms often rank higher in search results for certain high-volume keywords, which drives additional player acquisition without the overhead of licensing fees.

Regulators across Europe have tracked similar patterns in prior years yet the 2025 numbers mark a clear acceleration. The €12 billion total reflects net revenue after player winnings, and it underscores how cryptocurrency options facilitate faster deposits and withdrawals that licensed operators sometimes restrict due to banking rules. Studies found this payment method appears in roughly 35 percent of illegal transactions, providing a practical advantage in markets where traditional banking channels face delays or blocks.

Competitive Tactics Employed by Unlicensed Operators

Illegal sites compete by offering larger welcome bonuses and fewer verification steps compared with licensed platforms that must follow responsible gambling protocols. The research highlights how these operators actively target individuals already on self-exclusion lists, sending promotional messages through alternative channels that evade standard regulatory oversight. This approach sustains player engagement even when legal options become unavailable to the same users.

Traffic data collected by Helios demonstrates that many unlicensed domains maintain higher engagement metrics through aggressive marketing and rapid payout promotions. Researchers discovered these sites frequently update their bonus structures to retain users who might otherwise migrate back to regulated environments. The combination of crypto payments and relaxed bonus limits creates a cycle where players experience fewer friction points during deposits and withdrawals.

Implications for Licensed Markets and Regulatory Responses

Euromat commissioned the report to quantify the scale of activity occurring outside licensed channels, and the findings provide regulators with updated benchmarks for policy discussions. The 25 percent share of the overall online sector means licensed operators face ongoing pressure as illegal platforms capture revenue that would otherwise contribute to tax collections and consumer protection funds. Data shows this shift has continued steadily since 2019, with the tripling of illegal revenue occurring alongside slower growth in some regulated markets.

European authorities have responded with various enforcement actions including domain blocks and payment processor restrictions, yet the study indicates these measures have not fully contained the expansion. Cryptocurrency usage at 35 percent of transactions adds another layer of complexity because many digital currencies operate across borders without centralized oversight. Those who reviewed the traffic patterns observed that illegal operators adapt quickly to new blocking techniques by rotating domains and payment gateways.

Regional Variations Across the 28 Markets

Analysis of the 28 markets revealed uneven distribution of illegal activity, with certain countries experiencing higher penetration rates due to differences in enforcement resources and licensing availability. The report notes that markets with more restrictive legal frameworks tend to see greater migration toward unlicensed options, while jurisdictions offering competitive licensed products retain larger shares of player activity. This variation suggests enforcement and product design both influence outcomes.

Web traffic specialists at Helios contributed granular data on visitor origins and session lengths, allowing the researchers to cross-reference revenue models with actual usage patterns. The resulting estimates align with earlier industry observations that illegal operators often achieve higher conversion rates through simplified registration and instant bonus claims. Observers note these operational differences compound over time and help explain the tripling of revenue since 2019.

Conclusion

The Euromat-commissioned study supplies concrete numbers on a market segment that has grown to €12 billion in net revenue by 2025 while representing 25 percent of Europe's online gambling activity. Research indicates illegal operators rely on cryptocurrency payments, expansive bonuses, and targeted outreach to self-excluded players to sustain this position. As enforcement strategies evolve, the data provides a baseline for measuring future changes across the 28 examined markets.
