Anthropic files a legal challenge against the U.S. Department of Defense's decision to blacklist it

ChainCatcher News: Anthropic has announced that it will challenge the U.S. Department of Defense’s decision to blacklist the company in court. The department claims that Anthropic has refused to lift all restrictions on military use of its Claude model. The company also stated that it is “very upset” about the escalating dispute. This cutting-edge AI company is doing something few others have done since Trump’s return to the White House—publicly challenging the Trump administration.

Earlier on Friday, Trump and Defense Secretary Hegseth threatened to cut ties with Anthropic through a “supply chain risk” designation, a move traditionally used only against “foreign adversaries.” Anthropic stated, “No matter how the ‘Department of Defense’ intimidates or punishes us, it will not change our stance on mass surveillance or fully automated weapons.” “We will challenge any supply chain risk designation through legal channels.”
