Court Blocks Anthropic’s Bid to Lift Pentagon Blacklisting
A federal appeals court in Washington, D.C. has rejected Anthropic’s request to temporarily halt its national security blacklisting by the Pentagon. The decision marks a significant setback for the artificial intelligence company as it continues its legal battle with U.S. authorities.
Pentagon Labels Anthropic a Supply Chain Risk
The dispute stems from the Pentagon’s decision to classify Anthropic as a “supply chain risk” earlier this year. The designation followed the company’s refusal to remove certain safety guardrails from its AI systems as part of a Department of Defense contract.
As a result, Anthropic’s flagship Claude AI has been effectively excluded from use by defense contractors.
Mixed Court Rulings Create Uncertainty
Wednesday’s ruling represents a victory for the administration of President Donald Trump, especially after a previous court decision had temporarily prevented enforcement of a broader ban on Anthropic’s technology.
These conflicting rulings have created a complex legal situation for the company.
Anthropic Still Allowed Limited Government Work
Despite the setback, Anthropic is not entirely shut out of government work. The company can continue collaborating with non-defense agencies while the legal process unfolds.
However, the Pentagon’s classification means Anthropic remains effectively barred from securing defense-related contracts.
Legal Challenge Targets Pentagon Authority
In its lawsuit, Anthropic argued that Defense Secretary Pete Hegseth exceeded his authority by labeling the company a supply chain risk.
The case is expected to continue, with broader implications for how AI companies engage with national security institutions.
