A federal judge rejected the Trump administration's justification for designating Anthropic as a supply-chain risk, undermining the legal foundation for restricting the AI company's technology.

The ruling came after the administration moved to ban Anthropic's AI systems without providing substantial evidence that the company posed genuine threats to U.S. supply chains or national security. The judge found the government's claims insufficient to meet the legal threshold for such designations.

Anthropic, founded by former OpenAI researchers including Dario and Daniela Amodei, develops Claude, a large language model competing with OpenAI's GPT series. The Trump administration's supply-chain risk label would have effectively barred U.S. companies from using Anthropic's AI services, similar to restrictions placed on Chinese tech firms.

The company challenged the designation, arguing the administration presented no credible analysis showing how Anthropic's technology endangered American infrastructure or national security. The judge agreed, stating the government failed to meet its burden of proof. This decision blocks enforcement of the ban pending further proceedings.

The ruling reflects a broader tension over how aggressively the U.S. government should regulate domestic AI companies. Supply-chain risk designations typically target foreign entities like Huawei or DJI, not American firms. Applying this tool to Anthropic represented an unusual expansion of such authorities.

Legal experts noted the decision creates hurdles for future supply-chain designations against domestic AI companies without concrete evidence of harm. The Trump administration could appeal or attempt to build a stronger evidentiary case.

For Anthropic, the ruling protects its access to U.S. customers while regulatory battles continue. The company had argued the ban would damage American AI competitiveness globally and create unfair advantages for rivals like OpenAI.

The case remains active, with potential implications for how Washington regulates AI development. Federal courts
