Anthropic Sues Trump Administration Over “Supply Chain Risk” Designation, Calling It Unconstitutional Retaliation

In a dramatic escalation of tensions between the U.S. government and the artificial intelligence sector, Anthropic has filed two federal lawsuits against the Trump administration, challenging its designation of the AI company as a “supply chain risk to national security.” The move marks the first time an American company has received such a label, which has historically been reserved for entities linked to foreign adversaries.

The Constitutional Battle Begins

The lawsuits, filed simultaneously in the U.S. District Court for the Northern District of California and the U.S. Court of Appeals for the D.C. Circuit, argue that the administration’s actions constitute unlawful retaliation for protected speech and exceed statutory authority.

“There is a phrase in Anthropic’s court filing that sets the tone for everything that follows: ‘Anthropic turns to the judiciary as a last resort to vindicate its rights and halt the Executive’s unlawful campaign of retaliation,'” the company stated in its complaint. “It is the language of a company that believes it is not simply fighting a contract dispute, but a constitutional one.”

The Dispute’s Origins

The conflict centers on Anthropic’s insistence that its Claude AI system not be used for mass domestic surveillance of American citizens or for fully autonomous weapons systems capable of targeting and firing without human authorization. When the Pentagon demanded these restrictions be dropped in exchange for renewed contracts, Anthropic refused.

What followed was a rapid-fire sequence of events: On February 27, President Trump posted on Truth Social calling Anthropic a “radical left, woke company” and directing federal agencies to “immediately cease” all use of its technology. Within hours, Defense Secretary Pete Hegseth announced the supply chain risk designation.

Economic Stakes Run High

The practical implications are substantial. Anthropic executives warned that if the designation stands, it could reduce the company’s 2026 revenue by “multiple billions of dollars.” Chief Financial Officer Krishna Rao described the impact as “almost impossible to reverse,” while Chief Commercial Officer Paul Smith cited specific examples of lost contracts worth over $280 million.

However, the designation’s actual scope has proven narrower than initially suggested. Microsoft, Google, and Amazon all reviewed the designation and confirmed that Claude would remain available to their customers for work unrelated to defense contracts, contradicting Hegseth’s original announcement.

Legal Arguments Mount

Anthropic’s complaint makes two distinct legal arguments. First, it claims the administration’s actions violate the First Amendment by punishing the company for its public advocacy around AI safety and its positions on autonomous weapons and domestic surveillance. “The Constitution does not allow the government to wield its enormous power to punish a company for its protected speech,” the filing states.

Second, the company challenges the statutory basis of the designation, arguing that the Pentagon exceeded its authority under 10 USC 3252, which requires using “the least restrictive means” to protect the supply chain rather than deploying it as a punitive instrument.

Industry Solidarity Emerges

In an unusual display of unity, 37 researchers and engineers from OpenAI and Google DeepMind, including Google’s chief scientist Jeff Dean, filed an amicus brief supporting Anthropic’s lawsuit. The brief argues that the designation “chills professional debate” about AI risks and undermines American competitiveness.

“By silencing one lab,” the researchers wrote, “the government reduces the industry’s potential to innovate solutions.” This solidarity is particularly notable given that OpenAI struck a new deal with the Pentagon within hours of the Trump administration’s order—a move that drew sharp criticism from OpenAI employees.

Government Position and Contradictions

The Pentagon maintains that the dispute is fundamentally about operational control rather than speech, arguing that a private contractor cannot insert itself into the chain of command by restricting the lawful use of a critical capability.

However, Anthropic’s complaint highlights several contradictions: the military reportedly continued to use Claude during active combat operations in Iran after the ban was announced, a six-month phaseout was ordered simultaneously with an immediate prohibition, and Anthropic retains active FedRAMP authorization and facility and personnel security clearances that would ordinarily be incompatible with a national security risk finding.

What’s Next

A first hearing could take place as early as this Friday, with Anthropic asking for a temporary order allowing it to continue working with military contractors while the legal case unfolds. The Department of Defense has declined to comment on the litigation.

Legal observers have expressed skepticism that the designation will survive judicial scrutiny, noting that procurement laws passed by Congress do not give the Pentagon or the president authority to blacklist a company over a policy disagreement.

The Broader Implications

Whatever the court decides, the case has already set a precedent: a major AI company, backed by researchers at its own rivals, publicly litigating the government’s right to weaponize procurement law against a domestic company for taking a public stance on how its technology should and should not be used.

The outcome could determine, as Anthropic’s complaint puts it, whether any American company can “negotiate with the government” without risking its existence. This confrontation represents a pivotal moment in the evolving relationship between the technology sector and federal power, with implications that extend far beyond Anthropic’s immediate business concerns.
