A federal judge has ruled against the Pentagon's efforts to halt the use of Anthropic's AI tools, rejecting claims that the company posed a security risk.

The decision comes after President Trump and US Secretary of Defense Pete Hegseth ordered all government agencies to cease using Anthropic’s technology. Judge Rita Lin stated in her order that such actions were an attempt to ‘cripple’ the company and ‘chill public debate.’

Anthropic, whose tools are widely used by government and military departments, sees this as a victory for free speech. In contrast, the Pentagon's rhetoric has remained stern; US Undersecretary of Defense Emil Michael termed Judge Lin’s order ‘a disgrace,’ though he failed to provide evidence supporting his claim.

The legal battle began after Trump publicly berated Anthropic and Hegseth labeled it a 'supply chain risk,' a designation previously reserved for companies from adversarial nations. Anthropic argues that these actions not only impinged on its business but also violated its First Amendment rights. The Pentagon contends that the company's refusal to sign new contract terms, which could allow their tools to be used in mass surveillance and fully autonomous weapons, posed a national security threat.

The case highlights the growing tension between technological innovation and government oversight, with AI companies increasingly facing scrutiny over how their tools are deployed. Judge Lin’s ruling suggests that while this skirmish may have been won by Anthropic, the broader conflict is far from over.
