Germany’s online gambling industry is facing increasing scrutiny as new research raises questions about the true size of the country’s black market.
While regulators maintain that illegal gambling represents only a small share of the overall market, independent studies suggest the problem may be significantly larger — potentially accounting for more than half of all online gambling activity.
The growing discrepancy between official figures and independent estimates has triggered a wider debate about whether Germany’s current gambling regulation is effectively channeling players toward licensed operators.
Germany’s national gambling regulator, the Joint Gambling Authority of the Federal States (GGL), has argued that illegal gambling accounts for only a small fraction of the total market.
According to the regulator’s estimates, the channelisation rate — the share of gambling activity taking place on licensed platforms — exceeds 95 %, suggesting that less than 5 % of gambling activity occurs on illegal websites.
However, independent studies paint a very different picture.
A study by the Handelsblatt Research Institute concluded that the black market may actually represent more than 50 % of Germany’s online gambling sector, indicating that a large share of players could be using unlicensed platforms.
Other industry analyses have also suggested that the legal market may be attracting less than half of German online gamblers, particularly in certain product segments.
Research indicates that the biggest black-market imbalance appears in the online slot sector.
The Handelsblatt study suggests that 70 % to 80 % of virtual slot activity may occur on unlicensed platforms, making it one of the most difficult areas for regulators to control.
This segment is heavily regulated in Germany. Licensed operators must comply with strict product rules, including:
Critics argue that these restrictions can make licensed slot products less competitive compared with offshore alternatives.
Germany introduced its current regulatory framework in 2021 through the Interstate Treaty on Gambling, which unified gambling regulation across all federal states.
The law introduced strict consumer-protection measures such as nationwide deposit limits, centralized monitoring systems and extensive responsible-gambling tools.
But while these rules were designed to protect players, some industry stakeholders believe the regulatory model may also be contributing to the growth of unlicensed gambling.
The issue has become one of the most closely watched topics in the German gambling sector.
Trade associations and market analysts have increasingly argued that the competitiveness of the licensed market is essential for reducing illegal gambling activity.
According to Tim Buchmann, Chief Editor at CasinoBernie, the size of the black market remains one of the most important indicators of whether Germany’s regulatory framework is working as intended.
Buchmann, who analyzes regulatory developments and industry trends at the German casino comparison platform CasinoBernie, notes that measuring illegal gambling activity is inherently difficult.
“Black-market estimates vary widely because different studies use different methods,” he explains. “Some rely on consumer surveys, others on traffic analysis or tax data. That’s why the gap between regulatory estimates and independent research can be so large.”
The scale of illegal gambling has significant implications for both policymakers and players.
Unlicensed operators are not subject to Germany’s consumer-protection framework, which includes deposit limits, monitoring systems and self-exclusion tools.
As a result, gambling activity shifting to offshore platforms can reduce the effectiveness of responsible-gambling protections.
The black market also has economic consequences. When gambling activity takes place outside the licensed system, governments lose potential tax revenue and regulators lose oversight of the market.
Germany’s gambling framework remains relatively new, and regulators are expected to review parts of the system in the coming years.
The evaluation of the Interstate Treaty on Gambling, scheduled to conclude by the end of 2026, is expected to examine whether current rules are successfully channeling players toward the legal market.
Until then, the debate over Germany’s gambling black market is likely to remain one of the most important issues shaping the country’s online gambling industry.
