A federal appeals court in Washington, D.C., upheld the Pentagon’s decision to blacklist Anthropic, ruling that Claude’s integration with Department of Defense systems poses a “statutorily covered national-security risk.” The court affirmed that the blacklisting protects national security interests under existing statutes. The ruling reinforces the government’s authority to restrict AI tools that could compromise defense operations.
