TLDR France’s ANJ launched a new algorithm to measure revenue tied to excessive gambling behavior The tool flagged 600,000 high-risk players in H2 2025, making up 8.7% of all registered accounts Those players generated €1.2 billion in gross gaming revenue, or 60% of the total Operators reported only 89,000 excessive players between 2024–2025, far below the algorithm’s 600,000 figure The ANJ is pushing operators to act on the 300,000 players deemed “clearly excessive”
France’s gambling regulator, the Autorité Nationale des Jeux, has released data from a new algorithm that puts hard numbers on the link between problem gambling and operator revenue. The results paint a stark picture.
In the second half of 2025, the algorithm identified roughly 600,000 players at high risk of excessive gambling. That group made up 8.7% of all registered accounts on licensed French platforms.
Those 600,000 players were responsible for €1.2 billion in gross gaming revenue. That figure represents 60% of all revenue generated during the period.
The ANJ said the data shows a dual rise in both the number of at-risk players and the share of revenue they account for. The regulator described the situation as urgent.
How the Algorithm Works
The tool was developed in-house by the ANJ and is designed to reflect actual player behavior on online gambling platforms. It uses data points from player accounts to flag those showing patterns of excessive play.
ANJ Chair Isabelle Falque-Pierrotin said the algorithm’s release to operators marks a key step. She called it an innovative and effective tool that closely mirrors real gambling behavior.
Operators are not required to use the algorithm. However, the ANJ has made it available so companies can compare their own detection systems against the regulator’s benchmark.
The regulator sees the tool as a way to track trends
