Artificial intelligence company Anthropic has filed a lawsuit against multiple U.S. government agencies, claiming the federal government unfairly blacklisted its technology after the company refused to let its AI be used for certain military purposes.
The legal dispute focuses on Anthropic’s Claude AI models and the company’s restrictions against using them for autonomous weapons or mass surveillance of Americans. According to the lawsuit, tensions rose after government officials demanded that Anthropic remove these safety limits and allow the Department of War to make “all lawful use” of the technology. While Anthropic agreed to cooperate more broadly, it kept its two key safety restrictions in place.
The situation escalated after a directive from former President Donald Trump instructed federal agencies to immediately stop using Anthropic’s technology. Soon after, the Department of War labeled the company a “Supply-Chain Risk to National Security.” This designation blocked military contractors and partners from working with Anthropic, cutting the company out of the defense supply chain. Following this, several agencies canceled contracts or told employees to stop using the AI systems.
Anthropic says these actions violate the First Amendment, the Administrative Procedure Act, and constitutional due-process rights. The company argues that the government retaliated because it raised safety concerns about AI used in autonomous weapons and mass surveillance.
The complaint, filed in the U.S. District Court for the Northern District of California, seeks declaratory and injunctive relief against a wide range of federal entities and officials, including the Departments of War, Treasury, State, Homeland Security, the Federal Reserve, and the Securities and Exchange Commission.
Anthropic says the government’s actions have already led to canceled contracts and could risk hundreds of millions of dollars in business, while also damaging its reputation and commercial relationships. The company is asking the court to declare the government’s actions unlawful and to block enforcement of the directives while the case moves forward.
