Anthropic Supply Chain Injunction Takes Effect April 2; Pentagon Signals Ninth Circuit Appeal on First Amendment Grounds

The federal injunction blocking the Pentagon's supply chain risk designation of Anthropic takes effect April 2. Judge Rita Lin found the designation was retaliation for Anthropic's refusal to remove guardrails against autonomous weapons and mass surveillance, writing the Pentagon's own records show the action was driven by Anthropic's "hostile manner through the press." The DOJ is expected to seek a Ninth Circuit emergency stay. A parallel D.C. Circuit case continues.

Analysis
The Anthropic case has implications beyond one company: Judge Lin's ruling establishes that the supply chain risk designation cannot be used as retaliation for protected speech. If the Ninth Circuit upholds the injunction, it constrains the Pentagon's ability to pressure defense AI contractors into removing ethical guardrails. Anthropic's Claude remains integrated into Project Maven targeting systems even as the company is designated a national security risk for refusing to remove restrictions on those same systems.
