Anthropic Takes Legal Action Against Pentagon's AI Blacklisting
NEW YORK, March 9 - Anthropic has launched a lawsuit aimed at halting the Pentagon's attempt to blacklist the company, intensifying its ongoing conflict with the U.S. military regarding limitations on its artificial intelligence technology.
Last Thursday, the Pentagon imposed a formal supply-chain risk designation on Anthropic, citing concerns that its technology was being utilized for military operations in Iran.
In its legal filing in California, Anthropic contends that this designation is unlawful, infringing upon its rights to free speech and due process. The company is seeking judicial intervention to reverse the designation and prevent federal agencies from enforcing it.
“These actions are unprecedented and unlawful. The Constitution does not allow the government to wield its enormous power to punish a company for its protected speech,” Anthropic stated.
Defense Secretary Pete Hegseth labeled Anthropic as a national security supply-chain risk after the startup declined to eliminate safeguards against the use of its AI for autonomous weapons or domestic surveillance.
This designation poses significant risks to Anthropic's government contracts, potentially influencing how other AI firms negotiate military usage restrictions. However, CEO Dario Amodei emphasized that the designation has “a narrow scope,” allowing businesses to utilize its tools for projects unrelated to the Pentagon.
Former President Donald Trump has also instructed the government to cease collaboration with Anthropic, which counts Alphabet’s Google and Amazon among its financial backers. Both Trump and Hegseth indicated a six-month phase-out period.
Reports indicate that Anthropic’s investors are scrambling to mitigate the fallout from this conflict with the Pentagon.
The actions taken by Trump and Hegseth on February 27 followed extensive discussions with Anthropic regarding whether the company's policies could hinder military operations, shortly after Amodei's meeting with Hegseth aimed at reaching an agreement.

The Pentagon maintains that U.S. law—not private companies—will dictate national defense strategies, asserting the necessity for full flexibility in employing AI for “any lawful use.” They argue that Anthropic’s restrictions could jeopardize American lives.
Anthropic argues that even advanced AI models lack reliability for fully autonomous weapon systems, asserting that their deployment would be perilous. The company has also drawn a firm line against domestic surveillance of Americans, deeming it a violation of fundamental rights.
Following Hegseth’s announcement, Anthropic declared that the designation would be legally unsound and set a troubling precedent for companies negotiating with the government. The company vowed not to yield to “intimidation or punishment,” with Amodei reiterating their commitment to challenge the designation in court.
Amodei also expressed regret over an internal memo leaked to a tech news outlet, which suggested that Pentagon officials were displeased with the company partly because “we haven’t given dictator-style praise to Trump.”
In the past year, the Defense Department has signed agreements worth up to $200 million each with major AI labs, including Anthropic, OpenAI, and Google.
Shortly after Hegseth's move to blacklist Anthropic, Microsoft-backed OpenAI announced a deal to integrate its technology into the Defense Department's network. CEO Sam Altman noted that the Pentagon shares OpenAI’s principles of ensuring human oversight of weapon systems while opposing mass surveillance in the U.S.
