TL;DR

Anthropic CEO Dario Amodei has published a detailed response to the Pentagon’s formal supply-chain risk designation, arguing that the letter’s scope is narrow and applies only to Claude’s use within direct Department of War contracts. He confirmed Anthropic will challenge the designation in court and apologised for a leaked internal memo that criticised the Trump administration.

The Legal Argument

Amodei’s statement focuses on limiting the practical impact of the designation. He argues that under the relevant statute (10 USC 3252), the supply-chain risk label exists to protect government procurement — not to punish suppliers. The law requires the Secretary of War to use “the least restrictive means necessary” to protect the supply chain.

In practical terms, Amodei said this means the designation applies only to Claude’s use as a direct part of Department of War contracts. Even defence contractors are not restricted from using Claude for commercial work unrelated to their military contracts. Individual customers and broader business relationships remain unaffected.

Continued Military Support

Despite the legal dispute, Amodei struck a conciliatory tone on military cooperation. He said Anthropic would continue providing its models to the Department of War and national security community “at nominal cost and with continuing support from our engineers, for as long as is necessary to make that transition.”

He also reiterated that Anthropic’s two red lines — no fully autonomous weapons and no mass domestic surveillance — “relate to high-level usage areas, and not operational decision-making.” The company has consistently said it does not seek to control specific military operations.

The Leaked Memo

Amodei directly addressed the leaked internal memo that described OpenAI’s Pentagon deal as “safety theatre” and suggested the government relationship soured because Anthropic had not donated to or praised President Trump. He apologised for the tone, saying the post was written on a difficult day for the company and “does not reflect my careful or considered views.”

Looking Forward

The statement positions Anthropic as seeking to de-escalate while preparing for a legal fight. The court challenge will test whether supply-chain risk designations can be used against American companies for refusing to remove safety restrictions, a question with implications for every AI company that draws ethical boundaries around its technology’s use.
