What is digital sovereignty in AI? Definition and business implications
Digital sovereignty is the capacity of a company or a state to control its data, its infrastructure, and its AI tools, independently of foreign jurisdictions. It conditions confidentiality, regulatory compliance, and resilience to access disruptions dictated by external political decisions.
AI digital sovereignty covers three distinct dimensions. Data sovereignty: where is data stored, who can access it, under which jurisdiction? The US CLOUD Act (2018) allows the US administration to access data held by US providers, regardless of its physical location. European data hosted on AWS, Azure, or Google Cloud remains legally accessible. Model sovereignty: who controls the parameters, weights, and evolution of the model used? A closed proprietary model (GPT, Claude, Gemini) can be deprecated, modified, or made inaccessible unilaterally. Infrastructure sovereignty: on what chips, in which data centres, under which cloud actors are computations carried out? Europe, in November 2025, signed a Declaration for European Digital Sovereignty, and is preparing an EU Cloud and AI Development Act, scheduled for end of 2027, which will impose new requirements on cloud and AI providers active in the European market.
Concrete example
In January 2026, the French Ministry of the Armed Forces signed a 2026-2030 framework agreement with Mistral AI to deploy its models across all military branches, on the condition that the models be hosted on infrastructure controlled by the French state. The choice is not technical: OpenAI or Anthropic offer comparable performance. The choice is political and legal. For sensitive operations (defence logistics, intelligence analysis), full-stack sovereignty (data, model, infrastructure) prevails over raw performance benchmarks. The same logic applies, at a smaller scale, to any European company handling strategic or regulated data: health, banking, energy, industrial research.
