A federal appeals court in Washington, D.C. has rejected Anthropic's request to block the Pentagon from blacklisting the artificial intelligence company, differing from a previous ruling in a separate case in San Francisco federal court that forced the Trump administration to remove stigmatizing labels on Anthropic.

Why it matters

The conflicting court decisions have created substantial business uncertainty for Anthropic as it competes with other AI companies like OpenAI and Google in the race for AI supremacy. The case highlights the ongoing tensions between the tech industry and the Trump administration over the deployment of AI technology, particularly in military and surveillance applications.

The details

In the Washington, D.C. case, the appeals court acknowledged that Anthropic would 'likely suffer some degree of irreparable harm' if deemed a supply chain risk by the Pentagon, but said the 'precise amount of Anthropic's financial harm is not fully clear.' This differed from the San Francisco federal court's ruling, which found the Trump administration had overstepped its bounds in labeling Anthropic as a national security risk. The conflicting decisions have created uncertainty for Anthropic as it continues to battle the Trump administration in court.

  • On April 8, 2026, a federal appeals court in Washington, D.C. rejected Anthropic's request to block the Pentagon from blacklisting the company.
  • In a separate case in San Francisco federal court, a judge previously ruled that the Trump administration had to remove stigmatizing labels on Anthropic.
