The DC Circuit Court of Appeals ruled 2-1 that the Pentagon can blacklist Anthropic under 41 U.S.C. § 4713 for withholding Claude AI features from the military. The court held that no malicious intent is required under this statute, distinguishing it from the narrower 10 U.S.C. § 3252. Anthropic may seek en banc review or appeal to the Supreme Court.
Anthropic is directly affected, as the ruling upholds a ban on federal agencies and defense contractors using its products. Other AI companies with federal or defense contracts should monitor this precedent, as it expands the definition of supply-chain risk to include withholding features.
Anthropic's next legal steps—en banc or Supreme Court appeal. Also watch for any legislative response or executive action clarifying the scope of Section 4713. The Commerce Secretary's statement about patched relations may signal a political resolution.
