On Wednesday, Anthropic applied to a U.S. appeals court to suspend enforcement of the relevant ruling. The Pentagon previously designated the company as a supply chain risk entity, a designation the company said could cost it billions of dollars in revenue while the case undergoes judicial review. Anthropic's latest request comes after weeks of disputes over technical safety regulations for the use of its artificial intelligence tools by the U.S. military.

U.S. Defense Secretary Pete Hegseth has classified the company as a supply chain risk entity and banned the Pentagon and its contractors from using Anthropic's artificial intelligence products.

The artificial intelligence company filed a separate lawsuit in federal court in California earlier this week to challenge the Pentagon's blacklisting.

Anthropic filed a document with the U.S. Court of Appeals for the District of Columbia Circuit on Wednesday saying the Pentagon's supply chain risk determination would cause "irreparable harm" to the company.

According to Anthropic's court filings, more than 100 corporate clients have approached the company about the designation.

Lawyers for the artificial intelligence company wrote: "According to Anthropic's most conservative estimates, these adverse government actions may cause the company to lose hundreds of millions or even billions of dollars in revenue in 2026."

The Pentagon did not respond to a request for comment outside business hours.
