Court Overturns Pentagon’s Anthropic Blacklist

Anthropic wins against the Pentagon: court invalidates its blacklisting

A California judge overturns the Pentagon’s decision to exclude Anthropic from public contracts, calling it illegal. The startup, accused of refusing unrestricted military use of its AI, can now resume collaboration with the U.S. government.

A final court ruling

Judge Rita Lin in California ruled on August 28, 2026: the Pentagon’s blacklisting of Anthropic is "illegal and unfounded." She criticized the administration for using national security as a pretext to punish a company critical of the government. The measure, taken earlier this year, aimed to exclude Anthropic from public tenders after the company imposed limits on military use of its models, such as Claude.

The White House had then labeled Anthropic a "far-left, woke" company, allegedly seeking to "control military activity." Judge Lin dismissed this argument: "Invoking national security without evidence does not grant a free pass to sanction government critics."

Anthropic remains under pressure

While this victory is celebrated by the startup, which states it is "committed to working constructively with the government to put AI in the service of national security," another legal case still looms. In Washington, a proceeding could still exclude it from civils government contracts. The case remains pending.

Context: after leaks, tensions rise

This decision comes amid heightened tensions between AI giants and U.S. institutions. Microsoft has already tightened the confinement of its models after incidents this summer, while Anthropic, OpenAI and Google co-signed an open letter demanding a global response to AI-driven cyberattacks.

The court has ruled: the Pentagon cannot exclude Anthropic on political grounds. But the battle for access to public markets is far from over, and tensions between the industry and the U.S. government are intensifying.
