A federal judge has struck down the Pentagon’s attempt to blacklist Anthropic as a national-security supply-chain risk, ruling that the government unlawfully retaliated against the artificial intelligence company for publicly resisting unrestricted military use of its technology.
U.S. District Judge Rita F. Lin said the Defense Department’s actions were “illegal and baseless” and violated Anthropic’s First Amendment rights. The court also found that the company was denied due process under the Fifth Amendment and that the Pentagon’s designation was arbitrary and capricious.
The dispute began after Anthropic refused to remove safeguards preventing its Claude AI models from being used for domestic mass surveillance or fully autonomous weapons. The Pentagon wanted technology suppliers to permit their systems to be used for any lawful military purpose.
Defense Secretary Pete Hegseth subsequently designated Anthropic a supply-chain risk under rarely used federal procurement authorities. President Donald Trump also directed federal agencies to stop using Anthropic’s products, potentially cutting the company off from billions of dollars in government and contractor business.
The government argued that Anthropic’s restrictions created an operational risk because a private technology supplier could limit how the military uses a critical system after it becomes integrated into defense operations.
Lin rejected the government’s broader justification, finding insufficient evidence that Anthropic presented a genuine threat to the defense supply chain. She concluded that the designation was imposed because the company publicly disagreed with the administration’s AI policy.
The ruling requires the government to withdraw the challenged designation and related directives. It does not require the Pentagon to purchase or continue using Anthropic’s technology; the department remains free to select another supplier for legitimate contracting or operational reasons.
That distinction is important. The Pentagon can decide that Anthropic’s restrictions make Claude unsuitable for a particular military mission, but the court said it cannot use a national-security blacklist to punish the company across the federal government simply because the two sides disagree over acceptable uses of AI.
The decision represents a significant victory for Anthropic and could affect how Washington handles other technology companies whose products carry privately imposed safety rules. It also raises a larger question for government buyers: whether an AI developer can retain control over how its models are used after those systems become embedded in military operations.
Anthropic said it remains willing to work with the government on national security while maintaining safeguards against autonomous weapons and mass domestic surveillance.
The administration can appeal the ruling. A separate case involving another legal basis for the Pentagon’s designation remains pending in Washington.
