Anthropic Sues Department of Defense Over Supply-Chain Risk Designation

Anthropic has escalated its public clash with the Pentagon into a federal lawsuit, filed in California, challenging the Department of Defense's formal designation of the company as a 'supply-chain risk.' CEO Dario Amodei stated the company sees 'no choice but to challenge it in court,' arguing the action is legally unsound and constitutes unconstitutional retaliation for Anthropic's stance on limiting military use of its Claude AI models. The designation, which followed a dispute over whether the DoD could use Anthropic's technology for 'any lawful purpose,' including potential autonomous weapons applications, puts at risk hundreds of millions of dollars in annual revenue from the Pentagon and other federal agencies.

Legal experts note Anthropic faces a steep challenge, as rules granting the DoD authority to make such designations offer limited appeal avenues. The company's best legal argument may be demonstrating it was singled out, especially after rival OpenAI secured a new Pentagon contract with specific safeguards. The lawsuit warns that applying a 'supply-chain risk' label—historically used to exclude foreign tech like from China—to a US company sets a 'dangerous precedent.' A coalition of tech industry groups has urged the administration to reconsider the move, highlighting the high stakes for AI firms working with the government.
