Judge Shuts Down Trump’s Attempt to Blacklist Anthropic as a ‘Supply Chain Risk’

Back in 2019, when Anthropic was founded by former OpenAI employees, the pitch was that they’d be the responsible, safety-first AI company. Fast forward to 2026, and the Department of War tried to blacklist them as a “supply chain risk.” The reason? Not because they were selling AI models to enemies or harboring backdoors. No. The Department’s own records show they acted because of Anthropic’s “hostile manner through the press.”

US District Judge Rita Lin didn’t mince words. She called it “classic First Amendment retaliation” and granted Anthropic a preliminary injunction against the blacklisting. In her order, she wrote that by all appearances, “these measures appear designed to punish Anthropic.” That’s a pretty damning statement from a federal judge.

Let’s be clear about what was happening here. The Department of War, under Pete Hegseth and with Trump’s backing, tried to designate Anthropic as a prohibited source under the Federal Acquisition Regulation. That would have effectively locked them out of any government contracts and flagged them to every federal agency as untrustworthy. The justification was national security risk. But when the judge asked for evidence of an urgent threat, the Department came up empty.

Lin pointed out that officials seemingly had no authority to take such extreme actions without considering less restrictive alternatives or offering any evidence that Anthropic posed an urgent risk to national security. Instead, the only documented rationale was that Anthropic had been difficult in media interactions. This is the kind of behavior that makes people cynical about government power. You don’t like what a company says in the press? Slap a supply chain risk label on them and watch their business dry up.

The timing is interesting. Anthropic has been increasingly vocal about AI safety regulation, and they’ve taken positions that don’t always align with the current administration’s hands-off approach to AI development. Coincidence? Judge Lin didn’t think so.

This isn’t the first time we’ve seen the government try to use procurement power as a cudgel against companies that displease them politically. But it’s rare to see a judge call it out so directly and shut it down before it could do real damage. The preliminary injunction means Anthropic can continue operating normally while the case proceeds.

What’s particularly galling is the lack of evidence. If there were actual security concerns—if Anthropic had been caught exporting models to sanctioned countries or had vulnerabilities that could be exploited—that would be one thing. But punishing a company for being difficult in press interactions? That’s not how a constitutional republic is supposed to work.

The case will now move forward, but the injunction sends a clear signal: the courts are watching, and they’re not going to let executive overreach slide under the guise of national security. For Anthropic, this is a win, but it’s also a reminder that the government’s procurement powers can be weaponized against anyone who steps out of line. For the rest of us, it’s a reminder that the First Amendment still matters, even when the Department of War doesn’t like what you have to say.
