The Pentagon is keeping Anthropic on its supply chain risk list a week after a federal judge ordered the designation rescinded, setting up an unusually direct standoff between the Department of War and a district court.

 

Undersecretary of War Emil Michael said on September 3 that "Anthropic is still a designated Supply Chain Risk" at the department, according to the Washington Examiner.

 

Judge Rita F. Lin had ruled the opposite on August 27, granting Anthropic summary judgment and permanently enjoining the label she found was imposed as retaliation.

What Judge Lin's Ruling Struck Down

 

The case, Anthropic PBC v. U.S. Department of War, was decided in the U.S. District Court for the Northern District of California. Lin ruled for Anthropic on three independent grounds.

 

She found the designation was unlawful First Amendment retaliation, that it imposed what amounted to permanent debarment without the notice and hearing the Fifth Amendment requires, and that it exceeded the secretary's statutory authority under 10 U.S.C. § 3252.

 

The order reached beyond the label itself. Four things were vacated or enjoined:

 

  • The supply chain risk designation issued under 10 U.S.C. § 3252
  • A presidential directive clause barring defense contractors from any dealings with Anthropic
  • Implementing orders issued by nine federal agencies
  • Related guidance the government was directed to formally rescind

 

Lin was blunt about the government's national security justification, which she found unsupported by the contemporaneous record.

 

"The empty invocation of national security is not a blank check to punish and retaliate against government critics."

 

The opinion also noted that a vendor questioning its contracting terms does not thereby become "a potential adversary."

 

The Designation Still Standing on Appeal

 

The department's position is not quite as lawless as it first appears. A second, parallel designation of Anthropic under the Federal Acquisition Supply Chain Security Act, at 41 U.S.C. § 4713, was not before Judge Lin.

 

That one remains in effect and is on appeal before the U.S. Court of Appeals for the District of Columbia Circuit. It gives officials a live basis for saying the company is still designated, even with the § 3252 label enjoined.

 

The practical effect for Anthropic is that one legal track has closed in its favour while the other stays open, leaving federal buyers without a clean answer on whether the company can be contracted with.

 

How the Hegseth Designation Began

 

The dispute started with Anthropic's public objections to how its models were being used, specifically fully autonomous weapons and mass domestic surveillance applications.

 

War Secretary Pete Hegseth then designated the company a supply chain risk, a move that cut it out of Pentagon contracts and, through the directive clause, out of subcontracting relationships across the defense industrial base.

 

The sequence has run through the courts for most of the year:

 

  1. Anthropic publicly opposes autonomous weapons and domestic surveillance uses of its models
  2. Hegseth designates the company a supply chain risk under 10 U.S.C. § 3252
  3. March 26, 2026 — a judge grants a preliminary injunction; the Pentagon's chief technology officer says the ban stands anyway
  4. August 27, 2026 — Lin grants summary judgment and issues a permanent injunction
  5. September 3, 2026 — Michael states the designation remains in force

 

The March episode matters because it establishes a pattern. This is the second time the department has publicly maintained the designation after a court blocked it.

 

Exposure for Other Federal AI Vendors

 

Lin's reasoning is portable. Her holding that agencies cannot use a security label to punish a contractor for public criticism applies to any vendor weighing whether to object to how its technology is deployed.

 

Equally portable is the procedural finding. Treating a designation as a permanent debarment without notice or a hearing is a due process problem regardless of which company is on the receiving end.

 

Commerce Secretary Howard Lutnick has signalled a warmer line, saying recently that Anthropic is "back on the right side." That does not resolve the Department of War's position, which is set separately.

 

Anthropic welcomed the August ruling and said it wants a productive relationship with the government. The company has not said what it will do if the designation is not lifted in practice.

 

The open question is enforcement. A permanent injunction that an agency publicly declines to honour tends to end in contempt proceedings or an appellate stay, and the D.C. Circuit case gives the administration a reason to wait for one before conceding anything.
