Court Won’t Stop Trump’s Anthropic Blacklist

A federal appeals court refused to block the Trump administration’s blacklisting of Anthropic, denying the AI company’s emergency request for a stay. The decision came from judges appointed by Trump, leaving Anthropic without legal protection against the ban.

Anthropic, the San Francisco startup behind Claude, had asked the court to halt the blacklist while it challenged the order’s legality. The appeals court said no. Details on the exact grounds for the blacklist remain unclear, but the move effectively prevents Anthropic’s technology from operating in certain government and commercial contexts.

The ruling is a significant loss for Anthropic. Without the stay, the blacklist can continue while legal battles drag on—a process that typically takes months or years. The company now faces limited options for immediate relief in the courts.
