Explained: Why is the Pentagon locked in a dispute with Anthropic?

The US department of war (DoW), previously the department of defense, is reportedly planning to sever ties with the AI startup Anthropic.

This comes as the latter declined Pentagon’s requests to eliminate restrictions on the military's use of its AI tools, according to an Axios report.

What is the partnership between Anthropic and DoW?

In July 2025, the Dario Amodei-led startup announced that it was awarded a ‘two-year prototype other transaction agreement with a $200 million ceiling,’ to ‘prototype frontier AI capabilities’ for US national security. However, even before this contract, the company had already built a custom set of Claude Gov models for its US national security customers in June.


According to The Wall Street Journal and Axios, the US military deployed Anthropic's AI model Claude in the operation to capture former Venezuela president Nicolás Maduro earlier this year.

What is the dispute?

The dispute arose when the DoW pressured Anthropic, one among four other AI companies partnering with it, to allow unrestricted usage of their models for all purposes.

The report states that the department wants to use the AI application in sensitive areas such as weapons development, intelligence gathering, and battlefield operations.

Which other companies have been pressured and how have they responded?

Axios stated that Google, OpenAI, and xAI are the others who’ve faced such demands, and it’s likely they’ve been more accommodating of the same. Anthropic, which has been vocal on AI safety, has maintained strict boundaries around two areas — mass surveillance of citizens and fully autonomous weapons systems, the report added.

What has the Pentagon threatened Anthropic with?

The Pentagon is considering designating the startup as a ‘supply chain risk.’ This would mean that any company wanting to work with the US military would have to cut its ties with Anthropic. The Axios report added that defense secretary Pete Hegseth is close to terminating the two-year, $200-million deal.
