Microsoft, Google, and Amazon assure continued access to Anthropic Claude for non‑defense users

Major cloud and software providers Microsoft, Google, and Amazon have confirmed that Anthropic's Claude model will remain available to their customers for non‑defense workloads, despite the U.S. Department of Defense designating Anthropic as a supply‑chain risk. The designation, triggered by Anthropic's refusal to provide unrestricted access for certain military applications, does not affect the model's use in commercial or civilian projects. The companies say they will continue offering Claude through platforms such as Microsoft 365, Google Cloud, and AWS, and Anthropic plans to contest the designation in court.

Background

The U.S. Department of Defense officially labeled AI startup Anthropic as a supply‑chain risk after the company declined to grant unrestricted access to its Claude model for applications the company deemed unsafe, such as mass surveillance and fully autonomous weapons. This designation is typically reserved for foreign adversaries and means the Pentagon cannot use Anthropic’s products and must certify that contractors do not employ them.

Assurances from Major Tech Companies

Microsoft, the first large tech firm to address the issue, confirmed that it will keep Anthropic’s models, including Claude, available to its customers through services like Microsoft 365, GitHub, and its AI Foundry, except for direct Department of Defense contracts. A Microsoft spokesperson said the company’s legal review concluded that the designation does not bar the continued use of Claude for non‑defense purposes.

Google echoed this stance, stating that the determination does not prevent the company from working with Anthropic on non‑defense projects and that Claude will stay accessible via Google Cloud.

Amazon’s cloud division, AWS, also reported that its customers and partners can continue using Claude for workloads unrelated to defense contracts.

Anthropic’s Position

Anthropic CEO Dario Amodei reiterated that the supply‑chain risk designation applies only to Claude’s use in direct contracts with the Department of Defense and does not limit other customers or unrelated business relationships. He emphasized the company’s intent to fight the designation in court.

Implications for Customers

Enterprises and startups that integrate Claude through Microsoft, Google, or AWS platforms can proceed with their AI initiatives without interruption, provided the use is not tied to defense contracts. The assurances from the three tech giants help maintain confidence in the availability of advanced AI tools for commercial and civilian applications.

Ongoing Legal Challenge

Anthropic has vowed to challenge the Department of Defense’s designation in court, signaling a continued dispute over the balance between national security concerns and corporate control over AI technology.
