A federal appeals court in Washington D.C. denied Anthropic's request to block the Pentagon's supply chain risk designation, making it the first American company to receive a label historically reserved for foreign adversaries. The dispute originated when negotiations over a $200 million Pentagon contract stalled in September because Anthropic sought assurances its technology wouldn't be used for autonomous weapons or mass surveillance, while the DOD demanded unfettered access. Defense Secretary Pete Hegseth declared Anthropic a supply chain risk in late February following President Trump's order for agencies to cease using Anthropic's technology with a six-month phase-out. While the appeals court ruled against Anthropic citing national security priorities during active military conflict, a separate San Francisco court injunction allows Anthropic to continue working with non-DOD government agencies during litigation.
