ANJ algorithm to intensify pressure on French gambling operators

Jake Pollard reports on a newly-launched algorithm designed by the Autorité Nationale des Jeux (ANJ) to identify at risk and problem gamblers. The tool will increase pressure on French operators to monitor and document the number of excessive or pathological gamblers among their client base.

This algorithm, the first of its kind in Europe, has identified 600,000 French players who are highly likely to be problem gamblers. However, beyond those statistics gathered in H2 2025, the new data presents a stark contrast with current figures for problem gamblers in France, which are estimated to have tripled between 2024 and 2025, but remain significantly lower, at 89,000.

No explanation was provided for the discrepancy between the two sets of numbers. Nevertheless, among the 600,000 players identified, 300,000 are “so clearly problem gamblers that their detection by operators is essential,” according to ANJ. The regulator also noted that while the upward trend since 2023 may be attributed to overall market growth, it “does not account for the entirety of the situation as the number of problem gamblers has increased at a faster rate than the total number of gamblers.”

Data divergence

The discrepancy is also “inconsistent with the size of operators’ player bases and prevalence studies,” ANJ stated, which will intensify pressure on operators to enhance their efforts in identifying individuals at risk of becoming problem gamblers. The French gambling regulator further disclosed that the 600,000 problem gamblers represent almost 9% of the total population of registered players and generated €1.2 billion in gross gaming revenue (GGR), or 60% of the total online gambling GGR in France.

Given one of its key regulatory priorities is “to place the reduction of excessive or problem gambling at the heart of the regulation of the sector and its expectations of gambling operators,” ANJ is requiring them to adopt the new algorithm “to comply with their compliance obligations and allow the regulator to objectively assess their progress in identifying problem gamblers and reducing the GGR generated by these players.”

The new system will also enable ANJ to compare the number of problem gamblers reported by operators with the number detected by the algorithm. The regulator emphasized that it “expects operators to detect those players who are clearly excessive (approximately 300,000) and to identify the entire population of excessive players as determined by the algorithm (around 600,000).”

Under pressure

The algorithm can be utilized alongside operators’ existing tools to pinpoint excessive or problem gamblers and is not intended to measure the precise number of problem gamblers or estimate the prevalence of problem gambling in the same way general population surveys do.

Nevertheless, operators may not welcome the prospect of potentially disclosing much higher volumes of GGR generated from problem gamblers than previously acknowledged. As similar initiatives are being implemented in Spain and the Netherlands, the impact of ANJ’s new tool will soon be felt by Dutch and Spanish operators as well.

Isabelle Falque-Pierrotin, President of ANJ, described the launch of the algorithm as “a decisive step forward for the regulator” and highlighted its ability to develop an innovative and effective instrument designed to closely reflect actual online gambler behavior.

She added that the algorithm facilitates “the objective identification of problem gamblers, an endeavor operators must undertake without delay” and should also be extended to the retail networks of PMU and FDJ United, “a goal we have been advocating for the two monopolies to pursue since 2020.”

End game

ANJ can confidently assert the accuracy of its data due to having complete visibility into French operators’ data and information streams, which they continuously transmit to the regulator. This formed the basis upon which the algorithm was developed starting in 2024, using 23 indicators or risk criteria to generate a single score for each player.

The indicators encompass financial transactions, gaming moderators, gaming activity and frequency, as well as the player’s history; dividing players into four categories: recreational gambler, moderate-risk gambler, problem gambler, and severe problem gambler. Its performance was validated and measured against the Canadian Problem Gambling Index (CPGI), under the supervision of a scientific committee comprising recognized researchers.

By focusing on identifying problem gamblers, this initiative places additional pressure on French operators, but remains consistent with ANJ’s objective of addressing the issue as comprehensively as possible. It aligns with the regulator’s aim of combating the ‘banalization’ of gambling or ensuring that sport is not associated with betting in the minds of French players and consumers.
