Anthropic has filed a lawsuit in a California district court alleging that the U.S. government illegally labeled the AI firm as a supply‑chain risk and ordered all federal agencies to stop using its technology. The company claims the designation, issued by the Trump administration, violates its First and Fifth Amendment rights and exceeds executive authority. The suit follows a series of agency cutoffs, including the General Services Administration terminating its contract, and a broader controversy over the Pentagon’s use of Anthropic’s AI models. Anthropic says it will challenge the designation in court while its major partners continue limited collaborations. Read more →

Anthropic has filed a lawsuit to block the Pentagon from adding the AI firm to a national‑security blocklist after the Department of Defense labeled it a supply‑chain risk. The company argues the designation violates free‑speech and due‑process rights and lacks statutory authority. The legal action follows weeks of tension with the Defense Department, which pressed Anthropic to remove safeguards against mass surveillance and autonomous weapons. Anthropic’s CEO Dario Amodei refused, leading to threats of contract cancellation and a broader government push to bar the firm from federal use. OpenAI later secured a deal with the Defense Department, emphasizing similar safety principles. Read more →

Anthropic seeks a temporary restraining order to keep working with military partners while the lawsuit proceeds.
