Amodei warns about autonomous weapons and mass domestic surveillance during a dispute over military access to Claude.

February 26 dates Amodei’s public refusal and safety warning, not the beginning of negotiations. Later government actions and court decisions appear in the account.
The safeguards dispute
On February 26, Anthropic CEO Dario Amodei refused to remove contractual restrictions on mass domestic surveillance and fully autonomous weapons. He said current frontier models were insufficiently reliable for weapons that select and engage targets without human involvement. Anthropic continued to support other national-security uses.

The Pentagon’s January strategy sought AI contracts permitting any lawful use and models without restrictions on lawful military applications. Its stated priority was faster military adoption. The dispute concerned who could set additional usage limits, rather than a general Anthropic prohibition on military work. The cited statements do not establish that Claude was used for mass domestic surveillance or fully autonomous targeting. U.S. Department of Defense ↗Anthropic ↗
Government response and litigation
President Trump and Defense Secretary Pete Hegseth announced government-use and contractor restrictions on February 27; a formal supply-chain-risk designation followed on March 3. Anthropic challenged the measures. U.S. District Court, Northern District of California ↗
The litigation had separate tracks: on April 8, the D.C. Circuit denied an emergency stay in the procurement case. That interim ruling was not a final decision on the merits, and the later California judgment should not be read as resolving every proceeding. U.S. Court of Appeals, District of Columbia Circuit ↗U.S. District Court, Northern District of California ↗
On August 27, Judge Rita Lin ruled that the challenged actions violated free-speech and due-process protections and that the designation was unlawful. The court left the government free to choose another vendor lawfully. The account records dated court decisions; it does not certify the final status of every appeal or procurement restriction.
