Judge Blocks Pentagon Blacklisting of Anthropic Over AI Safety
A judge stopped the Pentagon from blacklisting an AI company called Anthropic.
The Pentagon had labeled Anthropic a possible national security supply-chain risk.
This label could keep the company from receiving some military contracts.
The dispute began because Anthropic would not allow its Claude AI to be used for some surveillance or autonomous weapons.
Anthropic says AI is not reliable enough for autonomous weapons and that domestic surveillance could violate people’s rights.
The government says companies should not be able to limit military operations through contract restrictions.
The judge said the Pentagon’s decision was illegal and baseless.
Anthropic still has another lawsuit about a separate designation that could affect civilian government contracts.
A California federal judge blocked the Pentagon’s designation of Anthropic as a national security supply-chain risk.
Judge Rita Lin called the Pentagon’s decision “illegal and baseless” in a 59-page order.
The designation followed Anthropic’s refusal to permit Claude’s use for U.S. surveillance or autonomous weapons.
Anthropic alleges the Pentagon violated its free-speech and due-process rights and exceeded its authority.
The Justice Department argued Anthropic’s restrictions could create uncertainty and disrupt military operations involving Claude.

Authority and legality
Anthropic’s position
Anthropic alleges that Defense Secretary Pete Hegseth exceeded his authority and that the government violated its First Amendment free-speech rights and Fifth Amendment due-process rights.
Pentagon and Justice Department’s position
The government defended the designation as a response to contractual restrictions and national-security concerns, rather than retaliation against Anthropic’s views.
Military use of Claude
Anthropic’s position
Anthropic says its AI models are not reliable enough for autonomous weapons and opposes domestic surveillance as a violation of rights.
Pentagon and Justice Department’s position
The Pentagon says private companies should not be able to constrain military action. The Justice Department argued that Anthropic’s refusal to lift restrictions could create uncertainty about Claude’s use and risk disabling military systems during operations.
Effect of the designation
Anthropic’s position
Anthropic says the designation could lead to billions of dollars in lost business and reputational harm and argues that the decision was unsupported by facts.
Pentagon and Justice Department’s position
The designation blocked Anthropic from certain military contracts and was presented as a way to address risks that could expose military systems to infiltration or sabotage by adversaries.
