Trickstr unveils the first AI Reputation barometer of the CAC 40
Trickstr has developed a groundbreaking method to measure a brand's perception and visibility across artificial intelligences, even tracing the exact sources that shape its image.
AI Reputation: your new strategic challenge
With 800 million weekly users for ChatGPT alone, generative AIs are no longer just a tool — they have become your most demanding stakeholder. Every day, they form an opinion about your company, influencing clients, partners, and talent.
This is what we call AI Reputation: the perception, image, and authority of a brand in the eyes of artificial intelligences. For the first time, we have measured this phenomenon at scale by putting the CAC 40 under the microscope. Here is what we learned and why our approach is uniquely positioned to support you.
A new perception paradigm to master
How do AIs perceive you? Our exclusive barometer, conducted in partnership with Vectors, reveals that they act as "super-users," synthesizing thousands of sources to form a consolidated judgment. Your owned websites account for an average of 38% of their information, but media (22%) and especially forums and blogs (24%) — spaces you don't control — carry increasing weight. Ignoring these conversations means letting your reputation be shaped by chance.
Our analysis highlights surprising narrative biases and sometimes counterintuitive solutions. Forget conventional wisdom: the most differentiating factor for the AI Reputation of a large corporation is neither innovation nor financial performance, but employer brand. Employee reviews on platforms like Glassdoor or discussions on Reddit decisively shape your overall image. AIs also reward consistency: L'Oréal, ranked No. 1 in our study, stands out for its balance across 7 key dimensions, rather than isolated achievements.
Our unique method serving your strategic advantage
How do we deliver such precise and actionable insights? The strength of our approach lies in a methodology that is unique on the market, designed to decode the DNA of your AI Reputation.
- Unmatched scale and rigor: our study is not based on a handful of anecdotal tests. Here, we systematically administered 4,536 questions to five of the largest AI models (GPT-4o, Microsoft Copilot, Google Gemini 2.5, Grok 4, and Perplexity's Sonar) across seven fundamental dimensions of corporate reputation, from strategic vision to CSR.
- Diagnosing raw perception: this is the core of our differentiation. We do not correct AI responses. We analyze their perception as-is, including hallucinations, biases, and outdated information. Because it is precisely this perception — right or wrong — that is served to millions of users and that constitutes your true AI Reputation.
- Source traceability: we don't just give you a score. By analyzing over 22,800 sources cited in the CAC 40 study, we have demonstrated our investigative power. We map the origin of your perception down to the finest detail. We identify the URLs, platforms, and content that build or undermine your image, giving you a clear roadmap for action.
From SEO to GEO: take control of your narrative
SEO was about driving clicks. GEO (Generative Engine Optimization) is about better managing your presence and traffic coming from AI chatbots. Our approach aims to help you build credibility and control your narrative within AIs themselves. Understanding and steering your AI Reputation is a strategic imperative. Through our in-depth audits, monitoring dashboards, and tailor-made AI Reputation Playbooks, Trickstr gives you the keys to navigate this new frontier and turn what may appear as a risk into a genuine leadership opportunity.
Methodology
How do artificial intelligences evaluate CAC 40 companies? What sources influence this AI Reputation? To find out, several thousand questions were administered through an automated system to five generative AI models: ChatGPT (4o), Gemini (2.5 Flash), Perplexity, Grok 4, and Copilot. Seven key dimensions of corporate reputation were assessed: Strategic vision, Products & services, Innovation, Employer brand, Financial performance, CSR, and Brand equity. These results were then consolidated to establish the CAC 40 AI Reputation barometer — the first large-scale measurement of how AIs evaluate major French companies.
Which CAC 40 companies have the best AI Reputation score?
L'Oréal, Airbus, and Michelin on the podium of the CAC 40 AI Reputation ranking.
With a highly balanced and consistent AI perception, L'Oréal tops the overall ranking. Airbus and Michelin round out the podium in a study that heavily favors industrial companies. Michelin stands out for its consistency: it is the only company ranked in the top 5 in more than 4 out of seven categories.
The AI champions in each category studied are:
- Strategic vision: EssilorLuxottica
- Products & services: Airbus
- Innovation: Thales
- Employer brand: Michelin ·
- Financial performance: Safran
