Federal Judge Says Pentagon’s Supply Risk Label Was An Attempt to “Cripple Anthropic”

A federal judge in San Francisco has granted Anthropic a preliminary injunction against the Trump administration’s designation of the AI firm as a national “supply chain risk.” Judge Rita Lin described the Pentagon’s actions as “troubling” and an apparent effort to “cripple” the company in what she characterized as illegal First Amendment retaliation.

Judge Delivers Scathing Rebuke Over “Orwellian” Tactics

Lin delivered her ruling on Thursday, March 26, following a tense March 24 hearing where she grilled government lawyers about the blacklist’s legal foundation. Anthropic had sued the Trump administration to overturn the Pentagon’s designation and Trump’s ban, seeking to halt actions that were causing significant monetary and reputational harm.

Lin’s order now prohibits enforcement of both measures, blocking efforts to classify the AI firm as a national security threat.

“Punishing Anthropic for bringing public scrutiny to the government’s contracting position is classic illegal First Amendment retaliation,” Lin wrote in her order. Her language grew even sharper in a March 26 order:

“Nothing in the governing statute supports the Orwellian notion that an American company may be branded a potential adversary and saboteur of the U.S. for expressing disagreement with the government.”

Following the ruling, Anthropic said it was “grateful to the court for moving swiftly,” adding that while the case was necessary to protect the company, its customers, and its partners, it remains focused on working productively with the government to ensure all Americans benefit from safe, reliable AI. The U.S. Department of Defense (DoD) did not immediately respond to a request for comment.

From Contract Negotiations to Constitutional Crisis

The dispute traces back to July 2025, when Anthropic secured a $200 million Pentagon contract to integrate Claude into the Gen.mil platform. By September, negotiations stalled over the company’s insistence on restrictions prohibiting fully autonomous weapons and domestic surveillance applications, with CEO Dario Amodei warning against granting “unfettered access for any lawful use.”

The situation deteriorated rapidly in early 2026 after President Trump announced plans to blacklist Anthropic on February 27, ordering federal agencies to “immediately cease” using the company’s technology. Shortly afterward, Defense Secretary Pete Hegseth followed with a post on X and a formal letter declaring Anthropic a supply chain risk, marking the first time such foreign-threat designation rules were applied to a U.S. company.

Anthropic responded by filing suit on March 9, alleging unconstitutional government overreach and setting the stage for Lin’s intervention, which now preserves the company’s operational status pending a full trial. A number of third parties, including major tech giants, have filed legal briefs supporting Anthropic’s case, including Microsoft (MSFT), industry trade groups, rank-and-file tech workers, retired U.S. military leaders, a group of Catholic theologians, and 149 former judges.

What is the Best Defence Stock to Buy?

Anthropic remains a private company ahead of its potential initial public offering (IPO) this year. However, investors interested in AI and defense stocks can consider top players such as Nvidia (NVDA), Lockheed Martin (LMT), Meta (META), RTX (RTX), and Kratos Defense (KTOS) tracked by the TipRanks Stocks Comparison Tool.
