Court Rejects Anthropic Challenge to Pentagon Risk Label

A federal court denied Anthropic’s request to overturn the Defense Department’s designation of the company’s AI system as a supply-chain risk, leaving the Pentagon’s related restrictions in effect. The decision prevents Anthropic from resuming or expanding federal contracts where the label applies while the designation remains active.

Anthropic, a San Francisco-based developer of the Claude family of large language models, sued to set aside the Defense Department’s assessment. The company argued the designation was improper and would harm its ability to sell services to U.S. government agencies. The court declined to grant the relief Anthropic sought and did not vacate the department’s determination.

The Defense Department assigns supply-chain risk labels to software, services and hardware it finds could introduce vulnerabilities, dependencies or other security concerns into military systems. A designation can restrict or bar an agency’s use of a product, require additional security reviews, or obligate a vendor to complete specific mitigation measures before becoming eligible for contracts.

The court’s ruling leaves the Defense Department’s authority to make supply-chain risk determinations intact under existing procurement and security rules. Anthropic retains the option to pursue further judicial review or administrative remedies, depending on the company’s chosen legal strategy.

The dispute reflects growing interaction between commercial AI providers and federal security reviews as agencies scrutinize vendors and infrastructure tied to sensitive systems. Anthropic, founded in 2021 by former AI researchers, has marketed its models to enterprise and government customers and attracted significant private investment as demand for large language models has grown.

How the Defense Department and Anthropic proceed next will determine whether the company can regain access to affected contracts. Options include additional technical mitigation work by Anthropic, administrative appeals within Defense Department processes, or further litigation in the courts.
