France: OpenAI, Google, Anthropic Control 84% of AI Agent Market
View original source →France's Autorité de la concurrence published Opinion No. 26-A-05—a 3,700-page investigation concluding that three AI labs control over 84% of the global AI agent market, calling for mandatory interoperability standards and urgent regulatory intervention.
Key Points:
• The authority built its own AI agents, asked them 550 shopping-related questions, and logged exactly which websites they visited and cited—a direct behavioral methodology for measuring agent market power.
• OpenAI, Google, and Anthropic together hold over 84% of the global autonomous AI agent market, based on Sensor Tower data from May 2026.
• The authority called for mandatory interoperability standards, open data access requirements, and regulation of default AI placement by platform gatekeepers.
• The 3,700-page scope signals this is not a preliminary inquiry but a near-final market assessment with specific regulatory recommendations.
• The investigation runs parallel to similar concerns from the EU, UK, and FTC—suggesting coordinated international regulatory pressure is building.
An 84% concentration in a technology category that did not exist three years ago is extraordinarily high by historical standards. Mandatory interoperability requirements—if enacted—would force platforms to allow users to switch AI providers without losing data, workflows, or agent configurations.
Why It Matters: The 84% figure quantifies vendor concentration risk in concrete terms. The behavioral testing methodology will likely be replicated by other regulators worldwide.
