German law enforcement raids suspected €5.8bn illegal online gambling ring
German authorities have conducted a major crackdown on an alleged illegal online gambling operation suspected of facilitating wagers totalling approximately €5.86 billion over a 30-month period.
According to the German Press Agency, the Frankfurt public prosecutor’s office, together with the Frankfurt tax investigation unit, the State Office for the Combat of Financial Crime in North Rhine-Westphalia and Frankfurt police, executed coordinated searches across 11 premises on Tuesday.
Over 100 officers participated in the operation. Authorities seized several high-value vehicles, froze numerous bank accounts and imposed an asset restraint order valued at around €82 million. An arrest warrant was also executed.
Prosecutors allege that five suspects had operated internet-based gambling services without the required German licences from at least July 2021. The volume of bets placed on these platforms reportedly exceeded €5.8 billion between mid-2021 and the end of 2023.
In addition to illegal gambling, investigators suspect extensive tax evasion, with a projected tax shortfall of about €77.6 million for 2024.
DSWV: Raid exposes true scale of black market
The DSWV, representing licensed sports-betting operators, broadly welcomed the law enforcement action as a necessary response to the illegal market’s growth and associated risks.
“This successful investigation clearly demonstrates the scale that the illegal gambling market has now reached,” said Mathias Dahms, president of the DSWV.
Dahms highlighted the significant dangers unlicensed operators pose to player protection and the overall integrity of the licensed market. He cited the absence of controls such as deposit limits, identity verification and player suspension tools.
He also called for continued rigorous enforcement efforts alongside strict regulation to safeguard consumers, adding: “Anyone who wants to strengthen player protection must therefore consistently crack down on illegal services and strengthen legal ones.”
The DSWV said the findings should prompt a thorough reassessment of official black market size estimates in Germany.
DOCV demands federal licensing for online casino
The DOCV, another trade body representing licensed online casino operators in Germany, also expressed support for the prosecutorial efforts. However, it emphasised that the raid exposed regulatory gaps which had allowed organised crime to flourish.
Kevin O’Neal, a DOCV board member, argued the scale of the investigation calls the GGL’s broader black market estimates into question. He cited the regulator’s 2025 activity report, which put the 2024 share at 23% (€547 million in gross gaming revenue), against Nielsen data suggesting a share of around 56%.
The trade body has long been critical over the discrepancy between channelisation estimates made by the regulator, and other independent reviewers.
The DOCV reinforced its calls for a unified federal licensing regime for online casino games and stronger enforcement mechanisms against illegal operators.
An ongoing review of the Interstate Treaty on Gambling, which is meant to conclude by the end of this year, should introduce a nationwide licensing model for online casino games, the group added.
As part of the review, German regulators decided in July to lift the €1 staking limit on online slots, another signal that regulators are actively reassessing the framework ahead of the treaty’s formal review.
