Anthropic CEO Dario Amodei said the company will challenge the Pentagon's supply chain risk designation in court, while arguing that the 'vast majority' of its customers will not be impacted. The Defense Department confirmed the designation in a letter to Anthropic, but the CEO said the restrictions only apply to the company's use by the military, not all of its customers.

Why it matters

The supply chain risk designation typically limits defense contractors from using a company's products, which could have wide-reaching consequences for Anthropic's business. However, Amodei believes the restrictions do not bar all of Anthropic's customers from using its technology, including Microsoft, which has said its lawyers concluded Anthropic's products can remain available to non-defense customers.

The details

Amodei said Anthropic has been in 'productive conversations' with the Pentagon about ways the company can continue working with the department while adhering to its two restrictions on the military's use of its technology - mass domestic surveillance and fully autonomous lethal weapons. The CEO also apologized for an internal memo that suggested the 'real reasons' the Pentagon and Trump administration dislike Anthropic is because the company hasn't donated to the president, saying it does not reflect his 'careful or considered views'.

  • On March 2, 2026, Defense Secretary Pete Hegseth announced the Pentagon's supply chain risk designation for Anthropic.
  • On March 6, 2026, the Pentagon confirmed the designation in a letter to Anthropic.
