Report: 72% of iGaming revenue in Europe is unregulated

• Gaming Compliance International produced a new report for the Campaign for Fairer Gambling, focusing on the online gambling sector in Europe
• The report uncovered a significant increase in unregulated online gambling GGR in 2025, while revealing that 72% of the iGaming revenue on the Old Continent is in the hands of unregulated operators
• Executives at Gaming Compliance International and Campaign for Fairer Gambling discuss the new report

Illegal online gambling across Europe is growing, and more than half of the iGaming revenue is in the hands of unregulated gambling operators, a new report reveals.

Unregulated iGaming GGR up by 74%

That’s the conclusion of a new report, produced by Gaming Compliance International (GCI) for the Campaign for Fairer Gambling (CFG).

The newly released report, Online Gambling 2024–2025: EU 27 Europe, uncovered that the unregulated online GGR increased significantly in recent years, recording double-digit growth.

Per the data, unregulated online GGR was €52.6bn in 2023.

However, two years later, in 2025, unregulated online GGR skyrocketed by 74% to €91.6bn.

Equally as concerning, the report looked into the gambling activities of consumers from the 27 member countries that make up the European Union, uncovering that 72% of online gambling revenue is unregulated.

Europe’s online gambling marketplace in 2025 was an estimated €128.0bn, of which €91.6bn, or 72% as mentioned, was in the hands of gambling companies that were not locally regulated.

"That activity took place outside the local regulatory perimeter, with attendant risks for consumer protection, taxation, licensing and regulatory oversight," a press release from the CFG explains.

Europe fails with gambling policies enforcement

Ismail Vali, GCI’s President and Founder, and former Yield Sec CEO, acknowledged that the €91.6bn figure highlights the scale of unregulated online gambling activities taking place across Europe in 2025.

"Unregulated online operators, and their affiliate and influencer marketing supply chains, were behind 91% of the online content encountered by audiences interested in online gambling in 2025 — a warning of the scale of unregulated activity Europe could face next," he added.

Vali stressed that unregulated gambling operators lure customers and easily capture their attention even before they access the gambling website.

Derek Webb, CFG’s Founder, added that the €91.6bn in unregulated online gambling revenue in 2025 is a testament to the failure of Europe’s enforcement.

"That scale should focus attention on enforcement — on operators evading local rules and the infrastructure that enables them to reach European consumers," he added.

Webb explained that unregulated online gambling represents Europe’s "enforcement problem," and stressed that operators that have licenses from some jurisdictions are not permitted to operate everywhere.
