Key facts
- Decision Sept 25, 2026, U.S. Court of Appeals for the D.C. Circuit, 2–1
- Majority: Claude’s built-in restrictions and the unresolved contract dispute could make it unreliable for military operations; rejected free-speech and due-process claims
- Dissent (Henderson): the law does not treat ‘a contractor’s honest and upfront enforcement of restrictions’ as a supply-chain risk
- Anthropic noted that another federal court had held the parallel designation unlawful (Aug 27)
- Panel: Judge Gregory Katsas wrote the 43-page majority opinion, joined by Judge Neomi Rao; Judge Karen LeCraft Henderson dissented (8 pages) (Startup Fortune, citing the ruling)
- Oct 13, 2026: Anthropic petitioned the full D.C. Circuit for rehearing en banc (Bloomberg Law, CNBC, Reuters). Per CNBC, its lawyers argue the majority stretched a law aimed at hostile foreign actors so that it ‘presumptively reaches every government contractor’, and that the court overlooked evidence the designation was retaliation for Anthropic’s speech about AI safety. En banc review is discretionary and rarely granted; the designation stays in effect meanwhile
What happened
The ruling concerns a separate designation under a different statute from the one Judge Lin struck down in August, so two federal courts have now reached opposite outcomes on the government’s actions.
Why it matters
It suggests the US military can exclude AI vendors whose usage policies restrict military applications. That has direct consequences for how labs write their acceptable-use policies.
