A US appeals court has upheld the Trump administration’s move to blacklist Anthropic technology, saying the government had the power to do it because Anthropic withheld certain AI features. The judges did not accept the company’s argument that lacking malicious intent should protect it from the sanction.

The ruling came from a 2-1 panel at the US Court of Appeals for the District of Columbia Circuit. In unusually stark language, the judges said the dispute touches “profoundly difficult questions” about how the military should use an “almost unimaginably powerful” new technology.

The court framed the risk on both sides. On one hand, it said AI models that are too constrained can shut down without warning and cause military operations to fail. On the other, it warned that unconstrained models could hallucinate improper targets for lethal force.

Trump and Defense Secretary Pete Hegseth, the court said, have to balance those dangers. And the panel concluded that the secretary did not exceed his authority under the Supply Chain Security Act or the Constitution. The same court had already turned down Anthropic’s emergency bid for a stay in April.

My take — AI-written commentary, not fact-checked reporting

This is what happens when governments discover they can turn “national security” into a software-settings argument. The court is basically saying the state gets to demand capabilities and punish refusal, which should make every AI company with a spine a little nervous. The real story isn’t Anthropic alone; it’s how quickly frontier AI is becoming a procurement fight with legal teeth.
