Story summary

On September 25, 2026, the US Court of Appeals for the District of Columbia Circuit ruled against Anthropic, upholding the Pentagon's decision to blacklist the AI startup as a national security supply chain risk. This designation bars Anthropic from military contracts and restricts its technology use within the Defense Department. The court's 2-1 ruling supports the Pentagon’s stance that Anthropic's refusal to remove safety restrictions on its Claude model for autonomous weapons and mass surveillance was justified due to potential national security risks. Anthropic, which claims the designation has cost it billions in lost business, expressed disagreement with the decision but remains confident in pursuing further judicial review.
