Enterprises and startups that use Anthropic Claude through Microsoft and Google products need not fear that the model will be ripped from their reach, Microsoft and Google confirmed to TechCrunch. AWS customers and partners can also reportedly continue to use Claude for their non-defense associated workloads.

Microsoft was the first big tech company to offer assurance that Anthropic’s models will remain available to its customers even though the Trump administration’s Department of War — formally known as the Department of Defense — has escalated its feud with Anthropic.

The Defense Department officially designated the American AI startup as a supply-chain risk on Thursday after the AI company refused to give it unrestricted access to its tech for applications the company said its AI could not safely support, such as mass surveillance and fully autonomous weapons.

The supply-chain risk designation is typically reserved for foreign adversaries. For Anthropic, the designation means that the Pentagon won’t be able to use the company’s products once it transitions Claude off its systems. It also requires any company or agency that works with the Pentagon to certify that they don’t use Anthropic’s models, either. Anthropic has vowed to fight the designation in court.

Microsoft sells an array of products, from Office to its cloud, to many federal agencies, including the Defense Department. A Microsoft spokesperson said that the company will continue making Anthropic’s models available within its own products and to Microsoft customers.

“Our lawyers have studied the designation and have concluded that Anthropic products, including Claude, can remain available to our customers — other than the Department of War — through platforms such as M365, GitHub, and Microsoft’s AI Foundry, and that we can continue to work with Anthropic on non-defense related projects,” the spokesperson said in an email. CNBC first reported on the comment.

Google, which sells cloud computing, AI, and productivity tools federal agencies, has also confirmed that it will continue to make Claude available to its customers.

“We 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,” a Google spokesperson said.

CNBC also reported that AWS customers and partners can keep using Claude for their non-defense workloads.

This echoes what Anthropic CEO Dario Amodei said in his statement vowing to fight the 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,” Amodei said, adding, “Even for Department of War contractors, the supply chain risk designation doesn’t (and can’t) limit uses of Claude or business relationships with Anthropic if those are unrelated to their specific Department of War contracts.”

In the meantime, Claude’s consumer growth surge has continued after Anthropic refused to give in to the department’s demands.
