Judge Voids Pentagon Supply-Chain Risk Label on Anthropic

A federal judge voided the Pentagon's supply-chain risk label on Anthropic on Thursday, lifting sanctions that nine federal agencies had imposed on the company.

US District Judge Rita Lin, in California, vacated Defense Secretary Pete Hegseth's February 27 decision to label Anthropic a "supply-chain risk" and make the company ineligible for federal contracts, according to Wired. The ruling runs 59 pages.

What the ruling says

Lin found the designation amounted to "unlawful retaliation" in violation of the First Amendment and called the decision "arbitrary and capricious," TechCrunch reported. She also found Anthropic was denied due process under the Fifth Amendment.

"Though the Department of War is undisputedly free to select the AI vendor of its choice, the evidence demonstrates that the broad measures imposed on Anthropic were illegal and baseless," Lin wrote.

She was blunter still on the national-security justification: "The empty invocation of national security is not a blank check to punish and retaliate against government critics."

Lin described the government's motive directly, writing that its "words and deeds confirm that the challenged actions were based on a desire to make a public example out of Anthropic for its 'arrogance' in criticizing the government."

The scope of what was lifted

The decision does more than remove one label. Wired reported that Lin ruled nine agencies — including the Pentagon, the Treasury Department, the State Department, and the Department of Homeland Security — had improperly imposed sanctions on Anthropic, and the ruling removes those penalties.

It also lifted a second measure from Hegseth that had barred contractors and suppliers to the US military from doing business with Anthropic, which Lin called "arbitrary, capricious, an abuse of discretion, and otherwise not in accordance with law."

What the ruling does not do is force any purchase. Lin affirmed the Pentagon is not required to use Anthropic's models and is free to choose other vendors.

How the fight started

The dispute traces to contract terms, not technology. The Verge reported that Hegseth moved this past winter to renegotiate every AI lab's military contracts to permit "any lawful use," a change that would significantly expand the Pentagon's authority. Most labs signed. Anthropic held out on two restrictions: no mass surveillance of Americans, and no lethal autonomous weapons.

Wired put a figure on what was at stake — a $200 million deal to use Claude models for military applications — and reported that negotiations broke down in February, after which Hegseth was widely seen as punishing Anthropic with the supply-chain designation.

The Pentagon's stated rationale at the time, per Wired, was that giving Anthropic access to classified systems would "introduce unacceptable risk" if the lab could disable or alter its technology, for instance at a time of war. The Pentagon has denied it would use Anthropic models for anything but lawful purposes, and argued Anthropic was attempting to control the military's use of models it had paid for.

The contradictions Lin cited

Much of the ruling turns on inconsistency between the label and the government's own conduct. Lin pointed to Hegseth's proposal to apply the Defense Production Act to Anthropic, "which would mean the company was essential to national security rather than a threat to it," TechCrunch reported.

She also cited the Department of Defense continuing to pursue a contract with the company, and the government collaborating with Anthropic's newer model, Mythos, on cybersecurity. On the security premise itself, Lin found Anthropic "undisputedly lacks" backdoor access to its technology once it is handed to the DOD.

Reaction and what happens next

Anthropic spokesperson Danielle Cohen said in a statement: "We welcome the court's ruling that this supply-chain risk designation was unlawful. We remain focused on working productively with the government to harness AI for our national security."

A Pentagon spokesperson could not immediately be reached for comment, per Wired, and the department is expected to appeal.

This is also only half the docket. Anthropic filed two complaints against the DOD in March — one in a California district court, one in Washington, DC. TechCrunch reported the DC suit is still ongoing, so a second ruling on the same underlying dispute is still pending.

Why it matters for AI vendors

The following is analysis, not reporting from the sources above. The practical question this ruling puts to every frontier lab is whether refusing a government use case carries a survivable cost. Anthropic's two red lines — mass surveillance and lethal autonomous weapons — cost it federal eligibility for roughly six months, from the February designation to Thursday's decision. A district court has now said that price was illegally imposed, but the company still absorbed it while the case ran, and an appeal could extend the timeline further.

Watch two things: whether the DOD files that appeal, and how the pending DC case lands. Until both resolve, the precedent here is narrower than the headline suggests.
