Google says Anthropic AI will remain available on Google Cloud despite Pentagon risk designation

Google said it will continue offering artificial intelligence models from Anthropic to customers through its cloud platform, excluding defense-related work, a day after Microsoft issued a similar statement.

The announcements from two of the world’s largest cloud infrastructure providers follow the US Defense Department’s designation of Anthropic as a supply chain risk.

A Google spokesperson said Friday that the determination does not prevent the company from working with Anthropic on non defense related projects and that its products will remain available through platforms such as Google Cloud.

Anthropic’s Claude models are available through Google Cloud via the Vertex AI platform. Google is also a significant financial backer of the company. In January 2025, the search giant committed an additional $1 billion investment in Anthropic, adding to its previous $2 billion stake.

Anthropic uses Google Cloud infrastructure to train its models and recently expanded its partnership with the company, gaining access to up to one million of Google’s custom tensor processing units.

The dispute began after Anthropic declined to agree to new terms requested by the US Department of Defense regarding the use of its AI systems.

Following the disagreement, President Donald Trump instructed federal agencies to stop using Anthropic technology. Defense Secretary Pete Hegseth later said the Pentagon would phase out its work with the company over a six month period.

Some defense technology firms have already told employees to stop using Anthropic’s Claude models and switch to alternatives from rival providers such as OpenAI.

Microsoft was the first major cloud partner to confirm it would continue supporting Anthropic products despite the Pentagon designation.

Microsoft said Thursday that its lawyers reviewed the designation and concluded that Anthropic products, including Claude, can remain available to customers other than the Department of War.

Anthropic CEO Dario Amodei said the company plans to challenge the government’s supply chain risk designation in court.

A late Friday report confirmed that Amazon will also continue offering Anthropic’s artificial intelligence technology to its cloud customers, excluding work involving the Department of Defense.
