The Pentagon Branded Anthropic a Supply Chain Risk. Now It’s Scrambling to Build Its Own AI

The Pentagon labeled Anthropic a supply chain risk and is now moving forward with building its own AI models. This new AI development follows the dramatic breakdown in a $200 million deal between Anthropic and the Department of War (DoW) in February 2026. The contract ultimately fell apart over Anthropic’s proposed limits on mass domestic surveillance and fully autonomous weapons. The development also comes on the heels of two lawsuits Anthropic filed against the DoW after the agency labeled it a supply chain risk.

Pentagon Accelerates Internal AI Development

The DoW has confirmed that it is now engineering multiple government-owned large-language AI models. These alternatives are expected to become operational soon. Moreover, the department reports that the transition from current Anthropic AI systems is underway, but will take over a month to complete.

Chief Digital and AI Officer Cameron Stanley stated that engineering efforts are focused on secure, unrestricted models for classified environments. Other providers, including OpenAI and xAI, have secured agreements allowing their use in Pentagon systems.

Notably, Anthropic’s Claude AI was previously the first frontier model approved for classified networks under a July 2025 contract. The supply chain risk label, applied under 10 USC 3252, bars contractors from using Anthropic products in DoW-related activities.

The private company is currently challenging the Pentagon’s supply chain risk designation in court, arguing it lacks broad statutory authority. The risk label has also triggered backlash from employees at various tech giants, including OpenAI and Google GOOGL -0.17% ▼ , IBM IBM -0.41% ▼ , and Salesforce CRM -0.82% ▼ .

**Why the Pentagon Pursues AI Self-Reliance **

Tensions arise from differing views on how AI should be used. The U.S. military emphasizes the need for broad, lawful, and operational flexibility, while companies often seek to impose ethical safeguards and usage constraints. This has prompted the Pentagon to prioritize internal development and partnerships with compliant vendors.

Anthropic’s supply chain designation raises questions about future U.S. AI firms’ access to defense contracts. Investors track these developments closely, as government relations tend to impact private AI valuations and market positioning. The shift also shows growing emphasis on sovereign control of critical AI technologies for national security, amid Anthropic’s ongoing legal pushback.

Currently, the US military actively uses AI across multiple domains. Systems powered by large language models, including Anthropic’s Claude, are deployed to support war operations in locations such as Iran. The DoW also integrates AI for intelligence analysis, logistics, targeting assistance, and decision support under strict human oversight.
