For years, digital sovereignty was a conference buzzword: much invoked, rarely turned into decisions. On 16 June 2026, on the eve of VivaTech, Prime Minister Sébastien Lecornu put a symbolic stop to that: the Direction générale de la sécurité intérieure (DGSI) is dropping the American giant Palantir in favour of the French ChapsVision and its ArgonOS platform (AFP / Boursorama). French domestic intelligence, on its most sensitive data, is choosing a national technology — only six months after renewing its contract with Palantir. This is no longer an intention: it is an act, owned at the highest level of the State.
1. What happened
The DGSI is ending its partnership with Palantir, which had equipped part of its data analysis tools since 2016. To replace it, it has selected ChapsVision and its ArgonOS platform (Silicon.fr, The Next Web). The same day, the government announced an additional €655 million for AI under France 2030 (Public Sénat). The choice is presented as strategic: keeping control of intelligence data on a national solution.
2. The two protagonists

Palantir Technologies
American software company founded in 2003 (Peter Thiel, Alex Karp), with initial backing from the CIA through In-Q-Tel. Two flagship platforms: Gotham (intelligence and defence) and Foundry (enterprise data). Listed on the Nasdaq, more than $400 billion in market capitalisation, $1.6 billion in quarterly revenue. DGSI supplier since 2016 — until the December 2025 renewal, broken off six months later.

ChapsVision
French technology group founded in 2019 by Olivier Dellenbach. Its ArgonOS platform merges and analyses AI-augmented data (OSINT, visualisation). Growth through acquisitions (Sinequa, Systran…), €275 million raised, around 1,000 employees, 2,000 customers, €157 million in revenue in 2024 (+45%). It had already won over German intelligence a month earlier — the European alternative is no longer theoretical.
To grasp what France is replacing — and with what — two videos. First, the demonstration of Gotham, Palantir's tool for intelligence and defence:

And the French proposal, ArgonOS, presented by ChapsVision from the sovereign AI angle:

3. The trigger: when access closes
This decision did not come out of nowhere. It was revived by a brutal precedent: from 12 to 14 June 2026, the American administration ordered Anthropic to block access to its most powerful models — Fable 5 and Mythos 5 — for any foreign national, in the name of national security (Al Jazeera, TIME). We documented this in our decryption of export controls.
The lesson is simple: a critical technology supplied from abroad can be cut off overnight, on a political decision, with no notice and no recourse. What was a theoretical risk has become a concrete precedent. The State draws the consequence for its sovereign functions: do not entrust the core of your intelligence to a tool whose switch is held elsewhere.
4. Palantir versus ChapsVision: what really changes
| Palantir (outgoing) | ChapsVision (incoming) |
|---|---|
| American software company, Nasdaq-listed, > $400bn | French group, ~1,000 employees, €157M revenue |
| Gotham platform, DGSI supplier since 2016 | ArgonOS platform, already selected by German intelligence |
| Critical data with a company subject to US law | Critical data under French law and control |
| Dependence on a possible foreign decision | Continuity aligned with national sovereignty |
5. What it changes for a company
One might think the subject is reserved for State intelligence. It is not. The DGSI's reasoning applies to any organisation that has built an important process on a technology supplied from outside: a business application, an AI model, a data platform.
Choose an AI that is suited, not merely powerful. The right model depends on the use, the data and the framework — not on the best-known name. A controlled AI is often worth more than a spectacular but uncontrolled one.
Keep control of your data. Knowing where your data lives, under which law, and who can cut off access becomes a decision criterion on a par with price and performance.
Turn the constraint into a method. Sovereignty is not a slogan to display: it is an architecture to design, tools to choose, teams to train. That is where real autonomy is won.
Fact: on 16 June 2026, France replaced Palantir with ChapsVision on the most sensitive data of its intelligence service, and released €655 million for its AI autonomy. Hypothesis: public procurement will keep reorienting towards sovereign solutions, and this way of reading will win over IT departments. Opinion: sovereignty has just stopped being a posture and become a purchasing decision — and the real question, for you, is not to be "for" or "against", but to know which AI serves your stakes without exposing you.
