What to know about Defense Protection Act and the Pentagon’s Anthropic ultimatum

NEW YORK (AP) — Defense Secretary Pete Hegseth gave Anthropic an ultimatum this week: Open its artificial intelligence technology for unrestricted military use by Friday, or risk losing its government contract.

Defense officials in the Trump administration also warned they could designate Anthropic, which makes the AI chatbot Claude, as a supply chain risk — or invoke a Cold War-era law called the Defense Production Act to give the military more sweeping authority to use its products, even if the company doesn’t approve.
