Anthropic Sues Pentagon Over 'Supply Chain Risk' Label After Refusing Military Use of Claude

Anthropic has filed federal lawsuits against the U.S. government challenging a Department of Defense designation that it is a 'supply chain risk'.

The company has sued the U.S. government in both the Northern District of California and the D.C. Circuit, naming nearly three dozen defendants including federal agencies and their leaders.

Other outlets reported the suits were filed 'in federal court in California' after the Pentagon’s formal designation.

One account noted Anthropic filed two suits: one in U.S. District Court for the Northern District of California and a second in the D.C. Circuit.

Anthropic says the dispute stems from the company’s refusal to allow Claude to be used for fully autonomous weapons or mass domestic surveillance, and it frames those limits as technical and safety judgments rather than political stances.

Anthropic says its bans on using Claude for domestic surveillance and fully autonomous weapons reflect technical limits and safety judgments, and several outlets emphasize that Anthropic has refused to allow its technology to power autonomous weapons or mass surveillance systems in the United States.

The company’s CEO and spokespeople have repeatedly warned about model reliability for such uses and described their safeguards as central to their mission.

Anthropic argues the Pentagon's actions amount to unlawful retaliation that infringes the company's constitutional rights and exceeds statutory authority.

Reporting says Anthropic contends the designation 'unlawfully punishes the company for its speech.'

The complaint alleges the measures are retaliatory and amount to unlawful retaliation for Anthropic's speech and other protected activities, infringing its First Amendment rights.

The company is challenging the statutory basis for the designation and is seeking judicial relief to vacate and block enforcement of the label.

One summary explains the legal challenge targets both constitutional and statutory grounds, including specific procurement authorities cited by the Pentagon.

The dispute escalated after a series of public steps by President Trump and Defense Secretary Pete Hegseth that pressed federal agencies to drop Anthropic’s tools.

According to reports, after talks missed the Pentagon’s Feb. 27 deadline, Trump announced on Truth Social that all federal agencies must 'immediately cease all use of Anthropic technology.'

Hegseth said he would label Anthropic a 'national security supply chain risk.'

Hegseth said he has officially notified the company it is barred from doing business with the Pentagon and its defense contractors.

News outlets note the Pentagon designation 'bars use of Anthropic’s AI, Claude, in matters directly tied to the department; some agencies have begun offboarding the tool.'

The company says the consequences have already included canceled federal contracts and other harms.

Anthropic and analysts warn the case could have broader industry and policy consequences, and the company says it will continue both litigation and dialogue.

Coverage notes Anthropic seeks to vacate the designation, block its enforcement and compel agencies to withdraw directives, while also saying it "will seek judicial review while continuing to pursue dialogue with the government and other resolutions."

Observers and the company warn the actions have prompted defense contractors to cut ties and could damage U.S. competitiveness in AI.

Others caution the lawsuit’s outcome could set a precedent for how AI firms and the government negotiate restrictions on military and surveillance applications.

Some major tech firms, however, say they can continue non-defense work with Anthropic even as the dispute proceeds.
