Frankfurt authorities raided eleven premises on 11 September 2026, ending a three-year investigation into an alleged illegal gambling ring whose total stakes are said to be worth almost €6bn (£5.1bn).
More than 100 officers from the Frankfurt Prosecutor’s Office, the Frankfurt Tax Office, the North Rhine-Westphalia Counter-Financial Crime State Office and Frankfurt police took part in the coordinated operation, which the prosecutor’s office said followed a three-year probe. Five suspects allegedly ran an unlicensed online casino between 2021 and 2023, processing more than €5.8bn in wagers, according to official government sources cited in the reporting that broke the story.
Officers seized several luxury vehicles, froze bank accounts and executed a property freezing injunction with a combined value of around €82m. At least one arrest has been confirmed, and that person also faces tax evasion charges covering at least €77.6m in unpaid taxes.
A black market bigger than the estimates assume
The scale of a single case has prompted Germany’s Sports Betting Association (DSWV) to argue that official assumptions about the size of the country’s illegal gambling market are too low. Its president, Mathias Dahms, said the raids dealt a major blow to illegal gambling but questioned whether the black market was being underestimated.
“Nearly €6bn in wagers over two-and-a-half years in a single investigation must prompt a critical review of previous assumptions about the size of the black market.”
Dahms said if one case revealed such proportions, it raised the question of whether existing estimates realistically reflected the illegal market’s scope. Industry estimates delivered by H2 Gambling Capital in 2025 put channelisation for Germany’s licensed online slots, the share of gambling flowing to legal operators, at between 22% and 25%, with a projected fall as low as 20% by 2030 if no key reforms are introduced.
Both the DSWV, whose members hold licensed betting, and H2 Gambling Capital have a commercial interest in a larger black market narrative, and the channelisation figures are industry-commissioned. The suspects remain unnamed, and only the tax evasion case is established; all other conduct is alleged.
The raids landed days after the Financial Action Task Force published a money-laundering risk review covering 80 financial jurisdictions that deemed online gambling a high-risk sector, and the same week illegal gambling was the focus of the annual knowledge exchange between DACHL, the German-speaking gambling authorities. Germany’s Gaming in Germany conference is scheduled for November 2026.
