An American court has blocked an attempt to exclude Anthropic from part of the military procurement market, setting the first clear limit on the use of the national security argument in disputes between the state and AI suppliers.
On 27 August, Federal Judge Rita Lin ruled that the Pentagon’s decision to designate Anthropic as a risk to the supply chain was unlawful. According to the court, the administration’s actions constituted retaliation for the company’s stance on the applications of artificial intelligence and infringed, amongst other things, its rights under the First Amendment.
The dispute began after Anthropic refused to allow Claude to be used for mass surveillance in the US and in fully autonomous weapon systems. The company argues that current AI models are not reliable enough for such applications. The Pentagon responded that a private supplier should not restrict the military’s lawful use of the technology.
The stakes extend beyond a single manufacturer. As recently as July 2025, the Pentagon awarded Anthropic a contract worth up to $200 million to develop advanced AI applications for national security. Other suppliers have also been awarded similar contracts.
The ruling may limit the ability to use supply chain security procedures as a leverage tool in negotiations with technology firms. However, it does not resolve the wider issue: who ultimately sets the limits on the use of AI models purchased by the state.
Nor is the dispute over yet. Anthropic is involved in a second legal case relating to a separate designation by the Pentagon, which could affect the company’s access to civilian federal contracts.
