German authorities have launched a significant offensive against an alleged illegal online gambling ring thought to have facilitated wagers amounting to approximately €5.86 billion over a span of 30 months.
On Tuesday, coordinated searches were conducted across 11 locations by a coalition that included the Frankfurt public prosecutor’s office, the Frankfurt tax investigation unit, the State Office for the Combat of Financial Crime in North Rhine-Westphalia, and the Frankfurt police. Over 100 officers participated in the initiative, which resulted in the seizure of several luxury vehicles, the freezing of multiple bank accounts, and an asset restraint order estimated at around €82 million. An arrest warrant was also executed during this operation.
Prosecutors allege that five individuals managed internet-based gambling services without obtaining the necessary licenses from German authorities since at least July 2021. The volume of bets placed on these platforms reportedly reached over €5.8 billion from mid-2021 to the end of 2023.
In addition to the illegal gambling operations, investigators are looking into significant tax evasion, predicting a tax shortfall of approximately €77.6 million for 2024.
In response to the crackdown, the Deutsche Sportwettenverband (DSWV), which represents licensed sports-betting operators, broadly welcomed the law enforcement efforts, highlighting the ongoing risks associated with the growth of the illegal market. "This successful investigation clearly demonstrates the scale that the illegal gambling market has now reached," stated DSWV president Mathias Dahms. He underscored the threats posed by unlicensed operators to player safety and the integrity of the licensed market, citing the lack of critical controls such as deposit limits, identity verification, and player suspension measures.
Dahms emphasized the need for continuous enforcement alongside robust regulations to protect consumers and asserted, "Anyone who wants to strengthen player protection must therefore consistently crack down on illegal services and strengthen legal ones." He added that the findings from this investigation should prompt a thorough reassessment of black market size estimates in Germany.
The Deutsche Online-Casino Verban (DOCV), another trade group for licensed online casino operators, also expressed support for the prosecutorial efforts, while cautioning that the raid highlighted regulatory deficiencies that have allowed organized crime to thrive. DOCV board member Kevin O’Neal pointed out that the scale of the investigation raises questions about the broader black market estimates released by the GGL, which, according to their 2025 report, forecasted a 2024 market share of 23% (€547 million in gross gaming revenue). This is in stark contrast to Nielsen data, which suggests a much higher share of around 56%.
The DOCV has consistently criticized the disparity between the channelization estimates made by the regulator and those from independent reviewers. The group reiterated its calls for the establishment of a unified federal licensing regime for online casino games and improved enforcement against illegal operators.
As part of an ongoing review of the Interstate Treaty on Gambling, German regulators announced in July their decision to lift the €1 staking limit on online slots, a move that indicates a proactive reassessment of the regulatory framework ahead of the treaty’s formal review set to conclude by the end of the year.
