Court denies Anthropic bid to block Pentagon risk label

A federal court this week declined Anthropic’s request for immediate relief from the Defense Department’s designation labeling the AI developer a “supply chain risk,” leaving the label and associated procurement limits in place while the company pursues its broader challenge.

Anthropic asked the court to set aside the designation and to bar agencies from treating the label as a barrier to contracts. The company argued the designation was unlawful, procedurally flawed and caused commercial harm by discouraging federal customers and partners from using its models.

The court rejected Anthropic’s request for preliminary relief, concluding the company had not met the legal standard for emergency injunctive relief. The judge said Anthropic failed to show a likelihood of success on the merits, did not demonstrate irreparable harm at the required level, and did not tip the balance of equities in its favor.

The dispute centers on a Defense Department action that flagged Anthropic as a potential supply chain vulnerability in government procurements of artificial intelligence services. Agencies and contractors have treated the designation as a signal to pause or limit use of Anthropic’s models for sensitive government workloads, including systems that handle classified, controlled or sensitive data.

In court filings, the Pentagon defended its designation as part of routine risk-management procedures designed to protect national-security systems and data. Department lawyers argued the determination rests on statutory and regulatory authority and that courts typically defer to agencies’ technical and security judgments in national-security and procurement contexts.

The court’s ruling covered only the preliminary injunction request and did not resolve the underlying legality of the Pentagon’s action. A full hearing on the merits will address whether the department followed required procedures and whether the factual basis for the label meets legal standards.

A legal practitioner commented that denying an initial injunction is a common early hurdle in administrative disputes with the government and does not decide the final outcome. Observers expect plaintiffs in similar cases often proceed to a full merits hearing and, when appropriate, appeal interim rulings.

Anthropic said it will continue its legal challenge and seek a complete review of the Defense Department’s procedures and evidence supporting the designation. The Defense Department said its assessments are necessary to protect critical technology systems and that agencies must be able to rely on department evaluations when deciding procurement and integration choices.

The outcome leaves immediate consequences for Anthropic’s government business pipeline. Contractors and agencies relying on Defense Department guidance may continue to limit procurement or integration of Anthropic’s models until the designation is withdrawn, overturned or otherwise resolved by the courts.
