Anthropic has filed a lawsuit against the US Department of Defense and other federal agencies over a supply chain risk designation. The company challenges the Trump administration’s decision that restricts its work with defense contractors. The dispute centers on failed talks about surveillance use and a Pentagon contract valued at up to $200 million.

Anthropic Challenges Federal Supply Chain Risk Designation

Anthropic filed the lawsuit after federal agencies labeled the company a supply chain risk and restricted defense partnerships. The designation followed collapsed talks between the company and defense officials over permitted uses of its systems. Federal officials insisted the technology must support all lawful purposes, including surveillance and weapons programs.

However, Anthropic refused to allow its systems for mass surveillance of Americans or autonomous weapons. As talks ended, the government halted adoption plans and jeopardized a Pentagon deal worth up to $200 million. The company argues the classification lacks legal basis and seeks judicial review to protect its operations.

An Anthropic spokesperson told CNN, “Seeking judicial review does not change our longstanding commitment to harnessing AI to protect our national security.” The spokesperson added that the lawsuit protects its business, customers, and partners. Meanwhile, the Pentagon maintained that lawful use requirements remain essential for defense technology.

Defense Contract Dispute and Corporate Responses

The Financial Times reported that Chief Executive Dario Amodei sought last-minute negotiations with defense leaders. He attempted to de-escalate tensions and prevent a formal blacklist. However, the effort failed to stop the supply chain risk classification.

Following the designation, federal agencies limited cooperation with Anthropic in defense projects. The Pentagon stated that contractors must ensure full lawful access to deployed systems. Officials maintained that defense technology providers must meet comprehensive operational requirements.

Despite the government dispute, Anthropic’s consumer business showed resilience. The company’s Claude application surpassed OpenAI’s ChatGPT in Apple App Store rankings after news of the contract termination. By early March, Anthropic reported that more than one million users signed up for Claude daily.

Major technology companies responded to the federal classification with public statements. Google confirmed it would continue providing Anthropic technology to cloud customers for non-defense purposes. Microsoft issued a similar statement, and Amazon said it would maintain access outside defense work.

Anthropic continues discussions with government officials while pursuing its lawsuit in federal court. The company maintains that the designation lacks a clear statutory foundation. As of early March, more than one million users join Claude daily, according to company data
