US court upholds Pentagon’s blacklisting of Anthropic

US court upholds Pentagon’s blacklisting of Anthropic Conflict began in February when Anthropic refused to remove restrictions on use of Claude for fully autonomous weapons. A United States appeals court has upheld the Defense Department’s decision to exclude Anthropic from its supply chain, a decision taken when the AI startup refused to remove certain safeguards on its Claude model. The court issued its ruling on Friday.

The supply chain risk designation, made in March, cancelled Anthropic’s military contracts and barred other Defense Department contractors from using its technology. Anthropic has said the blacklisting has cost it billions of dollars in lost business and damaged its reputation ahead of a highly anticipated initial public offering. The designation against Anthropic marked a highly unusual application of the authority against a US company. The company has since become a pariah at the White House, even as it plays a major role in the highly crucial AI sector and heads for a blockbuster IPO expected in the coming weeks. The White House has bristled at Anthropic CEO Dario Amodei’s repeated warnings about the dangers of AI, with US President Donald Trump calling them a hoax. The appeals court decision created a potential legal conflict with a separate federal court decision in California last month that found a broader ban imposed by the Trump administration against Anthropic was illegal. The Pentagon decision upheld on Friday was based on public procurement regulations and now remains in effect. “We respectfully disagree with the court’s decision. Another federal court has already held the government’s parallel designation unlawful. We remain confident in our position and are considering all options, including further review,” an Anthropic spokesperson said in a statement to US media. The military had reportedly been using Claude across a range of classified and sensitive systems, including during the January operation that captured and deposed Venezuelan leader Nicolas Maduro.
