A San Francisco court ruled the Pentagon unlawfully blacklisted Anthropic.
The action violated the First Amendment.
Anthropic still faces a pending Washington case.
What happened
A federal court in San Francisco ruled that the Pentagon unlawfully classified Anthropic as a supply chain risk, violating the First Amendment. The ruling came after negotiations over military use of Claude AI models collapsed in March.
Why it matters
The blacklist was seen as retaliation for Anthropic's public criticism of government AI policy. With Anthropic's planned IPO this fall, the court's decision carries weight because the designation could create problems even though a related Washington case is still pending.
What to watch
Anthropic technically remains on the blacklist while the Washington case is pending. The government has shown willingness to act against companies, as it did with its brief ban on Fable.

The court's decision marks a significant legal check on the government's power to designate companies as supply chain risks. The case stems from a disagreement over the terms for military use of Anthropic's Claude AI models, with the company seeking assurances against use in autonomous weapons and mass surveillance. The ruling suggests that the Pentagon's action was not just a procurement decision but a retaliatory measure that violated constitutional protections.
The timing is critical for Anthropic, as it prepares for a planned IPO this fall. A blacklist designation could create obstacles for the company, even though the San Francisco ruling is favorable. The pending case in Washington means the situation is not fully resolved, and the government continues to demonstrate its willingness to act against companies, as seen in its brief ban on Fable.
