Tech giants say Anthropic tools will remain available for nondefense work

Three major tech companies — Microsoft, Google and Amazon — have said Anthropic’s AI tools will remain available on their platforms for work that does not involve the Pentagon after the company was labeled a supply chain risk.

A Google spokesperson said in a statement Friday that they “understand that the Determination does not preclude us from working with Anthropic on non-defense related projects, and their products remain available through our platforms, like Google Cloud.”

Customers and partners with Amazon’s cloud computing arm, Amazon Web Services (AWS), can also continue to use Anthropic’s Claude for work not associated with the Defense Department, a company spokesperson said Friday.

“For all DoW workloads which use Anthropic technologies, we are supporting customers and partners as they transition to alternatives running on AWS,” they added, using an abbreviation for the Department of War, which is the Trump administration’s preferred name for the Defense Department.

Their assessments line up with Microsoft, which said Thursday that its lawyers had “concluded that Anthropic products, including Claude, can remain available to our customers—other than the Department of War” and that it can continue working with the company on nondefense projects.

Defense Secretary Pete Hegseth announced last Friday he was designating Anthropic as a supply chain risk after negotiations broke down over the terms of service for the company’s AI models.

The Pentagon officially notified Anthropic of the designation Wednesday. The AI firm’s CEO, Dario Amodei, said Thursday that it would challenge the label in court, arguing the move is not “legally sound.”

While Hegseth initially suggested this would bar any company that does business with the military from doing business with Anthropic, Amodei noted the language the Pentagon used in its formal notification matches the firm’s view that “the vast majority of our customers are unaffected by a supply chain risk designation.”

“With respect to our customers, it plainly applies only to the use of Claude by customers as a direct part of contracts with the Department of War, not all use of Claude by customers who have such contracts,” the Anthropic CEO said.

Amodei also said the company has “been having productive” with the Pentagon in recent days and offered an apology for an internal memo critical of the Trump administration that was leaked to the media.

“Anthropic did not leak this post nor direct anyone else to do so—it is not in our interest to escalate this situation,” he said.

“It was a difficult day for the company, and I apologize for the tone of the post,” he added. “It does not reflect my careful or considered views. It was also written six days ago, and is an out-of-date assessment of the current situation.”

Despite Amodei’s reference to conversations, Emil Michael, under secretary of Defense for research and engineering, said late Thursday there was no “active” negotiation between the Pentagon and the company.
