Anthropic refuses to remove safeguards for Pentagon AI use

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.

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.
