Google, Microsoft, Amazon Keep Anthropic AI for Non‑Defense Use
Following the U.S. Department of Defense’s designation of Anthropic as a supply‑chain risk, Microsoft, Google and Amazon (AWS) told customers they will continue to offer Anthropic’s Claude model for non‑defense workloads. Microsoft said Anthropic products, including Claude, can remain available to customers (except the Defense Department) via platforms such as M365, GitHub and Microsoft’s AI Foundry. Google confirmed the Determination does not prevent working with Anthropic on non‑defense projects and said products remain available through Google Cloud. CNBC reported AWS customers and partners can also continue to use Claude for non‑defense associated workloads. Anthropic CEO Dario Amodei said the DoD designation applies only to Department of Defense contracts, vowed to fight the designation in court, and noted non‑DoD uses are unaffected. The dispute follows federal procurement and national‑security scrutiny of Anthropic’s model access policies.
Major cloud providers (Google, Microsoft, Amazon) publicly clarifying availability of a leading LLM after a DoD supply‑chain designation affects enterprise and public‑sector AI procurement, vendor risk management, and cloud AI policy — important for infrastructure and platform governance.

Microsoft Stands by Anthropic Amid Pentagon Blacklist
Microsoft said it will continue to offer Anthropic's AI products inside its commercial products and platforms — excluding the U.S. Department of War — after the Pentagon designated Anthropic a supply‑chain risk. The Pentagon informed Anthropic of the designation; Anthropic said it intends to challenge the move in court. The article notes President Donald Trump had called for federal agencies to drop Anthropic and that Secretary of War Pete Hegseth limited Anthropic's Pentagon use to no more than six months.

Microsoft has previously integrated Anthropic models into Microsoft 365 Copilot and GitHub Copilot and has commercial agreements with Anthropic and OpenAI, including large cloud‑spend and investment commitments.
Anthropic Fights Back Against Pentagon's Supply Chain Designation
Anthropic CEO Dario Amodei said the U.S. government has officially designated Anthropic a supply-chain risk and that the company will challenge the designation in court. The dispute follows negotiations with the Department of Defense over access to Anthropic’s Claude models; the DOD reportedly sought unfettered access across lawful purposes while Anthropic sought exceptions for fully autonomous weapons and domestic mass surveillance. The designation requires defense vendors and contractors to certify they do not use Anthropic models in Pentagon work and marks the company as the only U.S. firm publicly named a supply-chain risk. Anthropic signed a $200 million DOD contract in July. Microsoft, which announced plans to invest up to $5 billion in Anthropic, said products can remain available to customers other than the DOD.
