22 percent. The Ministry of Labour's Bilan de l'égalité professionnelle 2025 puts France's unadjusted gender pay gap across disclosed tech roles at 22 percent: the widest such figure in Western Europe, four percentage points above Germany's 18 percent and nine above the Netherlands' 13 percent, both covered earlier in this August series. The figure is not new. What is new, as of June 7, 2026, is that the legal architecture designed to close it has been superseded in 23 of 27 EU member states, and France is not among the four that transposed on time.
France missed the EU Directive 2023/970/EU transposition deadline without implementing legislation. The Ministry of Labour now targets 2027, aligning France with Germany and the Netherlands in the non-transposing majority. Until that legislation passes, the operative framework for France's largest AI employers remains the Index d'Égalité Professionnelle, introduced under Law no. 2018-771 (Loi Avenir Professionnel). What that index measures, what it does not measure, and how Mistral AI, BNP Paribas, Société Générale, Capgemini, and Thales are behaving inside the gap: that is the question this briefing addresses.
The stakes are material. LinkedIn Talent Insights (Q2 2026) recorded a 48 percent year-on-year increase in AI and ML job postings across Île-de-France, the Paris metro area that concentrates France's frontier lab and enterprise AI hiring. A market expanding at nearly half again its prior-year posting volume, carrying the widest gender pay gap in the region, is a market where the disclosure architecture matters for who reaches these roles.
L'Index d'Égalité Professionnelle: The Existing Floor
DARES (Direction de l'animation de la recherche, des études et des statistiques) administers the Index under the Ministry of Labour. Companies with 50 or more employees must publish an annual composite score on a 0-to-100 scale by March 1 each year. Employers scoring below 75 must publish a corrective plan with measurable targets and a fixed timeframe. Employers who fail to publish the Index at all face fines of up to 1 percent of annual payroll under Articles L.1142-7 and L.1142-8 of the Code du travail, the same payroll-fraction penalty that EU Directive 2023/970/EU adopts for non-compliance under its own Article 23.
The Index scores five dimensions: the unadjusted pay gap between men and women in comparable roles (40 of 100 points); the gap in individual pay raises (20 points); the gap in promotions (15 points); the proportion of employees who receive a pay raise in the year of return from maternity leave (15 points); and the number of women among the ten highest-paid employees (10 points). What the Index does not require is that salary bands appear in job postings. A company can publish an Index score of 88 and post zero salary ranges in its AI role advertisements without any legal exposure under current French law. Under Directive 2023/970/EU, once transposed, that combination will not be compliant.
Per ENTRA's review of DARES published data (2025 publication cycle, covering the 2024 reference year), the four French AI-adjacent employers reviewed here score as follows: BNP Paribas at approximately 85/100; Société Générale at approximately 81/100; Capgemini at approximately 78/100; Thales Group at approximately 76/100, one point above the corrective-plan trigger. All four clear the statutory threshold. None of their Index scores reveal anything about what their AI job advertisements say about compensation.
Mistral AI: The Paris Disclosure Benchmark
Mistral AI, publisher of the Mistral 8x22B mixture-of-experts model family and the most widely cited salary disclosure reference in the Paris AI market, operates at 100 percent posting rate across its active AI roles as of Q2 2026, per ENTRA monitoring of the company's careers page and LinkedIn postings. Stated bands for Senior ML Engineer roles (Paris, Q2 2026) run from €108,000 to €142,000 base (~$118K to $155K equiv at EUR/USD 1.09), consistent with Levels.fyi benchmarks and the ENTRA Job Signal Index Q2 2026 Paris-cluster analysis.
The €108K-€142K base band positions Mistral below London's equivalent frontier-lab range, where DeepMind London Senior ML Engineer base compensation runs approximately £130,000 to £175,000 (~$165K to $222K equiv), and below Berlin's senior applied-AI tier, where Aleph Alpha's senior engineering band ran €155,000 to €185,000 base (~$169K to $202K equiv) in H1 2026. The structural differential against London and Berlin is partially offset by France's impatriats tax regime. Under Article 155B of the Code général des impôts (CGI), foreign nationals recruited from abroad who establish French tax residence benefit from a 30 percent exemption on employment income for up to eight years. Researchers and specialists meeting the additional qualification criteria under the same article access a 50 percent exemption on qualifying income under the "régime des impatriés chercheurs." The effective take-home gap between a €142,000 Mistral role and a £175,000 DeepMind London role narrows materially once the impatriats calculation is applied.
Arthur Mensch, Mistral's CEO, has framed the compensation differential in public terms. Quoted in Le Monde in March 2025: "Nous payons en mission. Nous payons en équité. Nous payons en propriété de l'IA européenne. L'écart en dollars est réel et nous l'acceptons." ("We pay in mission. We pay in equity. We pay in ownership of European AI. The dollar gap is real and we accept it.") The EU sovereignty thesis that anchors Mistral's recruitment proposition, including its open-weight model releases as infrastructure for European AI independence, is what 100 percent salary disclosure reinforces: transparency about the band, honesty about the gap, explicit framing of mission and equity as the differentiating variables.
The Grandes Entreprises Disclosure Gap
Below Mistral, the disclosure picture fragments by sector. ENTRA's Q2 2026 monitoring across LinkedIn France, Welcome to the Jungle, and direct company careers pages tracked AI-tagged role postings at the four grandes entreprises reviewed here. Estimated salary band disclosure rates: BNP Paribas and Société Générale combined at approximately 67 percent; Capgemini at approximately 58 percent; Thales at approximately 52 percent.
The 67 percent figure for the two French financial institutions reflects movement from the near-zero disclosure that characterised French financial sector posting practice as recently as 2023. Welcome to the Jungle's French Tech Salary Report (2025) found that 71 percent of active French tech job seekers ranked salary range disclosure as a top consideration or decisive in application decisions, a 22-percentage-point increase on the 2022 baseline. That candidate-market pressure, rather than legal compulsion, is driving the improvement.
Capgemini's 58 percent and Thales's 52 percent both reflect governance constraints that large French enterprises face when aligning international posting practice with candidate-market expectations. Thales operates AI hiring across its defense and civil aerospace divisions under security classification frameworks that create posting caution for roles touching Annex III high-risk systems under the EU AI Act, including AI deployed in aviation safety and defense-critical applications. That caution carries a cost in market position: a 52 percent disclosure rate in a talent pool where Mistral has normalised 100 percent creates a friction differential that does not resolve itself in candidate decisions.
The impatriats regime (Article 155B CGI) is available to all four employers for international AI talent recruitment, and all four deploy it. For BNP Paribas and Société Générale, recruiting AI engineers for Paris-based data science and AI risk modeling roles from across the EU, the 30 percent standard exemption and 50 percent researcher variant are material components of the net-pay offer. Because impatriats benefits apply to gross income and require recruiter-stage explanation rather than appearing in posting salary bands, employers that disclose bands early and explain the impatriats net-pay calculation alongside them convert the regime into a recruitment accelerant. Employers that neither disclose bands nor explain the regime systematically lose international AI candidates to markets where the math is legible from the first posting.
What France's 2027 Implementation Will Require
EU Directive 2023/970/EU establishes three obligations that France has not yet enacted. First, employers posting roles must include salary bands in job advertisements, disclosed prior to any interview. Second, employers with 250 or more staff must submit annual gender pay gap data disaggregated by occupational group. Third, where an occupational-group pay gap exceeds five percent and cannot be justified by gender-neutral criteria, the employer must undertake a joint pay assessment in cooperation with employee representatives: France's comité social et économique (CSE) and délégués syndicaux will carry this function when the implementing legislation takes effect.
The penalty ceiling under Directive Article 23 is 1 percent of annual payroll. For BNP Paribas and Société Générale, with France-based payrolls running into multiple billions of euros, that figure represents a meaningful compliance motivator. For Capgemini and Thales, the penalty arithmetic is comparably steep. The French government has not published a draft implementing law; the Ministry of Labour's position, as tracked by the European Commission DG EMPL transposition monitor, targets 2027 without a committed parliamentary introduction date.
France's 22 percent unadjusted gender pay gap will produce occupational-group figures well above the Directive's five-percent joint-assessment trigger for every large French tech employer at the senior AI engineering band. That means the 2027 obligation is not only a disclosure obligation but a joint-assessment obligation, requiring CSE engagement, documented remediation plans, and external reporting. French grandes entreprises that build disclosure practice now, and close the distance between their Index d'Égalité scores and their job posting transparency, will arrive at 2027 implementation with fewer gaps to fill under enforcement pressure rather than voluntary initiative.
Mistral AI's 100 percent posting rate at €108K-€142K, at a moment when the legal requirement is zero, is a positioning statement rather than a charitable act. In a Paris AI market growing at 48 percent per year, the employer that tells candidates what they will be paid before the law requires it is the employer that the strongest candidates choose to reach first.
