France and Germany take aim at Palantir

Chancellor Friedrich Merz (@_FriedrichMerz) and President Emmanuel Macron (@EmmanuelMacron) signed a joint pledge on Friday to examine the development of a "European sovereign digital backbone." According to Politico, the agreement names France's Arcadia platform as an example, alongside comparable German systems. It is an agreement to study, not a procurement decision, but it marks a clear political signal from Europe's two largest continental defence spenders.

Arcadia vs. Maven: Europe's Answer to NATO's AI Platform

Arcadia is France's military AI command-and-control platform, positioned as an alternative to Palantir's Maven Smart System. NCIA finalised the acquisition of the Palantir Maven Smart System NATO on 25 March 2025, and NATO personnel began training on the system that August, the alliance's first use of AI-enabled command and control software, according to Defense News.

General Patrick Justel, deputy chief of staff of the French Army, put it plainly in a media briefing: Arcadia "is our response to Maven." He said NATO's use of Maven raises questions of digital sovereignty: "The question arises whether we should adopt Maven blindly, or should we look for other solutions." The French system is designed to be decentralised, linking command posts via a mesh-network architecture rather than a central cloud, which French officials say makes it more resilient in combat conditions.

Arcadia has already seen action. The French Army tested the system in exercises Dacian Fall in Romania and Orion 26 in France, and deployed it at NATO's Coalition Warrior Interoperability Exercise (CWIX) in Poland from 8 to 26 June, its first multinational trial. The system was built with French industry partners including Mistral AI, Safran.AI, Thales, and Airbus.

France says Arcadia has been designed to comply with NATO's Federated Mission Networking (FMN) standards, a key framework for interoperability between allied forces. Palantir says its Maven system aligns with FMN principles and is working toward full certification. The competing interoperability claims are unresolved. And at least one senior NATO commander recently told Politico that no real European alternative yet exists, a reminder that Arcadia remains a work in progress rather than a finished product ready for alliance-wide deployment.

Worth noting on the industry side: Safran.AI is a development partner on Arcadia and, separately, a Palantir partner on the NATO Maven Smart System rollout, placing the same firm on both sides of the competition.

Intelligence Agencies Already Making the Switch

The Franco-German declaration follows a series of concrete procurement decisions. France's DGSI announced in June 2026 that it will replace Palantir with French firm ChapsVision for mass data analysis. Prime Minister Sébastien Lecornu tied the decision to a US order requiring Anthropic to restrict access to its most advanced AI models for foreign nationals, saying France must not rely on tools from foreign powers that could cut off access. Germany's domestic intelligence agency had made the same switch the month before, choosing ChapsVision over Palantir.

The transition will not happen overnight. Palantir's contract with the DGSI was renewed in late 2025, and its tools will remain in use while ChapsVision's platform is integrated, a process expected to take several years. ChapsVision, founded in 2019, has grown to more than 1,000 employees and reported nearly 200 million euros in revenue in 2024.

France is backing the shift with public money, announcing 655 million euros in new AI funding aimed at supporting domestic players. European partners are paying attention: Denmark is reportedly looking for local solutions to replace its own Palantir deal, and the Dutch State Secretary for Defence has said a "fully fledged alternative" to Palantir must be available within two years.
