# DoD Upholds Anthropic Supply-Chain Risk Designation

The U.S. Department of Defense (DoD) has retained its designation of Anthropic as a national security supply-chain risk following a ruling by the U.S. Court of Appeals for the District of Columbia Circuit. This decision upholds the Pentagon's authority under the Federal Acquisition Supply Chain Security Act of 2018 to exclude Anthropic's AI products, specifically its Claude AI models, from military systems and defense contracts due to concerns over the company's refusal to agree to contract terms deemed essential for national security. The ruling restricts Anthropic's participation in defense procurement and reinforces the DoD's discretion to manage supply chain risks related to AI technology providers. This outcome impacts defense contractors and AI vendors by signaling heightened scrutiny on contractual compliance and national security considerations in AI procurement.

- **Key agencies involved:** Department of Defense, D.C. Circuit Court of Appeals
- **Contract impact:** Ongoing $200 million contract dispute involving Anthropic's Claude AI models on classified defense systems remains affected by the exclusion
- **Procurement implications:** Defense contractors must comply with DoD supply chain security requirements and avoid using restricted AI technologies
- **Market impact:** Competitors such as OpenAI, Google, Microsoft, and xAI may benefit from expanded opportunities in DoD AI contracts
- **Legal precedent:** The ruling affirms DoD's authority to impose vendor usage limits based on national security, influencing future AI technology procurement policies

### Key Quotes
> The First Amendment squarely protects Anthropic’s advocacy regarding the safe and appropriate use of AI products, but the record in the case makes clear that the Department removed Anthropic from its supply chain not because of its advocacy, but because Anthropic refused to agree to a contract term the Department deemed essential to national security.
> — Circuit Judge Gregory Katsas

> The Department excluded Anthropic from its supply chain based on the company’s refusal to assent to a contract term that the Department deemed essential, not based on the company’s support for greater governmental regulation of AI technology.
> — Gregory G. Katsas, Circuit Judge

> The hammer of justice has smashed @AnthropicAI arguments. They are a supply-chain risk to the defense industrial base serving the @DeptofWar. Warfighters will sleep better knowing that no private company will insert their opinions in the chain of command. @SecWar was right!
> — Emil Michael, Defense Undersecretary
