Anthropic PBC v. U.S. Department of War
Issue
Whether the federal government's retaliatory termination of contracts, designation of Anthropic as a "Supply-Chain Risk to National Security" under 10 U.S.C. § 3252, and Presidential Directive ordering all agencies to cease use of Anthropic's technology violated the First Amendment's prohibition on government retaliation against protected speech, the Fifth Amendment's Due Process Clause, the APA, and separation-of-powers limits on executive authority.
What Happened
Anthropic filed a complaint for declaratory and injunctive relief in the N.D. California on March 9, 2026, after the President issued a social-media directive ordering every federal agency to immediately cease use of Anthropic's technology, and the Secretary of War subsequently designated Anthropic a "Supply-Chain Risk to National Security" and barred all military contractors from conducting commercial activity with the company. Anthropic alleges these Challenged Actions were triggered solely by its public refusal to remove usage restrictions prohibiting Claude's deployment for lethal autonomous warfare and mass surveillance of Americans—restrictions the Department of War had previously accepted. Anthropic argues the Secretarial Order and Letter violate 10 U.S.C. § 3252's plain text and required procedures, constitute APA-prohibited arbitrary and capricious agency action, effect unconstitutional First Amendment retaliation under *National Rifle Ass'n of America v. Vullo*, 602 U.S. 175 (2024), deprive Anthropic of property and liberty interests without due process, and exceed any congressionally delegated executive authority. The complaint seeks declarations of unlawfulness and injunctive relief halting implementation of all Challenged Actions.
Why It Matters
This case presents a novel First Amendment retaliation theory applied directly to a government AI procurement dispute, potentially establishing whether an AI developer's public statements about its model's safety limitations constitute protected speech that constrains the government's exercise of its contracting and national-security designation powers. A ruling on the merits could also define the procedural and substantive limits of 10 U.S.C. § 3252 supply-chain risk exclusions as applied to AI vendors, with significant implications for how AI companies may lawfully restrict government use of their systems.
