A federal court has granted Anthropic's request for a preliminary injunction, temporarily blocking the U.S. government from banning the company's products for federal use and from formally labeling it as a 'supply chain risk.' The judge ruled that the government's actions appear designed to 'punish Anthropic' for criticizing the government's position, which would constitute illegal First Amendment retaliation.

Why it matters

This case highlights tensions between the government and technology companies over the use of AI, as well as concerns about free speech and due process when the government seeks to restrict a company's ability to work with federal agencies.

The details

The dispute began when Anthropic refused to change the terms of its contract with the government to allow the use of its technology for mass surveillance and autonomous weapons development. In response, the Trump administration ordered federal agencies to stop using Anthropic's services and the Defense Department officially labeled the company as a 'supply chain risk,' typically a designation reserved for entities based in U.S. adversaries like China. Anthropic challenged the designation in court, arguing it was unlawful and violated its rights.

  • On March 27, 2026, the court granted Anthropic's request for a preliminary injunction.
  • Anthropic's lawsuit against the government is still ongoing, with the court yet to issue a final decision.
