A federal appeals court on Friday upheld the Pentagon’s designation of Anthropic as a national security supply chain risk, blocking the AI startup from military contracts and affirming the Defense Department’s authority to enforce the blacklist.
The U.S. Court of Appeals for the District of Columbia Circuit ruled 2-1 in favor of the Pentagon, rejecting Anthropic’s legal challenge to its designation under national security statutes. The decision comes amid ongoing disputes over the government’s power to restrict AI firms from defense-related work.
Core Facts of the Ruling
- The appeals court declined to block the Pentagon’s blacklist of Anthropic, a leading AI company known for its Claude language model, from all military contracts.
- The ruling affirmed the Pentagon’s authority to designate companies as national security risks based on supply chain concerns, citing potential vulnerabilities in AI integration.
Court Rationale and Legal Context
The majority opinion, authored by Circuit Judge Gregory Katsas and joined by Circuit Judge Neomi Rao, stated that the Pentagon had “ample support” for its conclusion that Anthropic’s AI model posed a statutorily covered national security risk. The court emphasized that Anthropic’s own restrictions on its AI’s capabilities—such as preventing certain tasks—were cited as evidence of potential control or misuse risks.
The opinion noted: “The Department had ample support for its conclusion that the continued integration of Claude into the Department's information systems, by the Department or its contractors, presented a statutorily covered national-security risk.”
Dissenting View
Circuit Judge Karen LeCraft Henderson dissented from the majority, though the specific grounds for her dissent were not detailed in the available reporting.
Anthropic’s Response and Legal Options
Anthropic expressed disagreement with the ruling, stating in a release that it respectfully disagrees with the decision but remains confident in its position. The company indicated it is considering further judicial review, including potential appeals to higher courts.
In prior legal challenges, a federal judge in San Francisco had struck down a separate but related Pentagon designation under a different law, ruling that the administration had unlawfully retaliated against Anthropic for its public stance on AI safety. That decision is under appeal.
Implications for AI and Defense Contracts
The ruling establishes a precedent for the Pentagon’s ability to blacklist AI firms from defense contracts based on supply chain risk assessments. Anthropic has warned that the designation could cause significant reputational damage and hundreds of millions in lost revenue, particularly ahead of a planned initial public offering.
The company has stated it does not allow its products to be used for autonomous weapons or mass domestic surveillance, though the Pentagon’s concerns appear to center on broader supply chain integrity and control over AI behavior.
Next Steps
The decision is final unless Anthropic pursues further appeals. The company’s legal team is reviewing options, including a potential petition for review by the full D.C. Circuit or the U.S. Supreme Court. The Pentagon has not immediately commented on the ruling beyond the court’s decision.
