The company's Claude chatbot is one of the few AI systems cleared for use in classified settings. But a standoff between Anthropic and the Trump administration is putting its government work at risk.

Until this week, Anthropic was the only AI company cleared to deploy its models on classified networks. Elon Musk's xAI is now the second.

Anthropic filed a lawsuit on Monday to block the Pentagon from placing it on a national security blacklist.

Pete Hegseth gave Anthropic CEO Dario Amodei until Friday to grant the Pentagon unrestricted access to Claude or face losing its defence contract and a government blacklist designation.

Secretary of Defense Pete Hegseth said the company that owns the AI assistant Claude would be punished unless it drops all ethical guidelines.

US defence secretary Pete Hegseth has threatened to cut Anthropic from his department’s supply chain unless it agrees to sign off on its technology being used in all lawful military applications by Friday.

Defense Secretary Pete Hegseth is pressuring Anthropic to give the military broader access to its artificial intelligence technology or lose its Pentagon contract.

Pentagon R&D chief Emil Michael said comments Anthropic CEO Dario Amodei made during a meeting at the Pentagon set off alarm bells.
