Several major US technology companies have backed Anthropic in its lawsuit challenging the US Department of Defence’s decision to label the AI company a national security ‘supply chain risk’.
Google, Amazon, Apple, and Microsoft have filed legal briefs supporting Anthropic’s attempt to overturn the designation issued by Defence Secretary Pete Hegseth. Anthropic argues the decision was retaliation after the company declined to allow its AI systems to be used for mass surveillance or autonomous weapons.
In court filings, the companies warned that the government’s action could have wider consequences for the technology sector. Microsoft said the decision could have ‘broad negative ramifications for the entire technology sector’.
Microsoft, which works closely with the US government and the Department of Defence, said it agreed with Anthropic’s position that AI systems should not be used to conduct domestic mass surveillance or enable autonomous machines to initiate warfare.
A joint amicus brief supporting Anthropic was also submitted by the Chamber of Progress, a technology policy organisation funded by companies including Google, Apple, Amazon and Nvidia. The group said it was concerned about the government penalising a company for its public statements.
The brief described the designation as ‘a potentially ruinous sanction’ for businesses and warned it could create a climate in which companies fear government retaliation for expressing views.
Anthropic’s lawsuit claims the government violated its free speech rights by retaliating against the company for comments made by its leadership. The dispute escalated after Anthropic declined to remove contractual restrictions preventing its AI models from being used for mass surveillance or autonomous weapons.
The company had previously introduced safeguards in government contracts to limit certain uses of its technology. Negotiations over revised contract language continued for several weeks before the disagreement became public.
Former military officials and technology policy advocates have also filed supporting briefs, warning that the decision could discourage companies from participating in national security projects if they fear retaliation for voicing concerns. The case is currently being heard in federal court in San Francisco.
