Anthropic files emergency en banc appeal over supply-chain risk designation by Department of War

Anthropic PBC has filed an emergency en banc petition with the full D.C. Circuit, seeking to overturn a 2–1 ruling that upheld Secretary of War Pete Hegseth's designation of the company as a national-security "supply chain risk." The filing (dated Oct 13, 2026) argues the designation was a direct response to Anthropic's public stance, citing a conflicting N.D. Cal. ruling that found it motivated by Anthropic's speech. The petition stresses that parallel designations issued the same day for the same reasons were condemned on First Amendment grounds in one forum and sustained in another, warranting full-court review.
