Google said it will continue to offer Anthropic’s AI technology to its clients, except for defense work, a day later microsoft issued a similar statement to customers.
The announcements from two of the three major cloud infrastructure providers follow the Department of Defense’s official designation of Anthropic as a supply chain risk.
“We understand that the Determination does not prevent us from working with Anthropic on non-defense projects, and their products continue to be available through our platforms, such as Google Cloud,” a Google spokesperson said Friday.
Amazonleader in public cloud, has not yet commented on the matter.
Anthropic’s Claude models are available through Google Cloud via the Vertex AI platform. The search giant is also a major financial backer of Anthropic and in January 2025 agreed to an additional $1 billion investment, adding to its previous $2 billion stake.
Anthropic uses Google Cloud’s AI infrastructure to train its models and recently expanded the partnership by gaining access to up to 1 million custom Google Tensor Processing Units (TPUs).
After Anthropic refused to agree to terms of use requested by the DOD last week, President Donald Trump ordered federal agencies to stop using the company’s technology, and Defense Secretary Pete Hegseth said his work with Anthropic would end in six months. CNBC has confirmed that the United States used anthropic models in its latest attack on Iran.
Some defense technology companies have told their employees to stop using Anthropic’s Claude models and switch to alternatives, including from rival OpenAI.
Microsoft was the first major partner to say it will continue working with Anthropic after the Pentagon’s actions.
“Our attorneys have studied the designation and have concluded that Anthropic products, including Claude, can remain available to our customers outside of the War Department,” Microsoft said late Thursday.
Anthropic CEO Dario Amodei said Thursday that his company has “no choice” but to challenge the supply chain risk designation in court.
