Anthropic Round 3

The series that translates national-security and AI-policy arguments across partisan lines, because the stakes are too high for tribal shorthand.

Anthropic Round 3: The Panel Was Hot

What Happened This Week

The D.C. Circuit heard Anthropic v. Department of War on May 19, and the panel did not sound like a rubber stamp. Judge Henderson called the designation "spectacular overreach." Judge Katsas, the likely swing, pressed both sides on whether procurement authority can become national AI policy by another name.

The case matters because the Pentagon's blacklist is no longer only about Anthropic. If the court narrows the designation, every agency using procurement to discipline AI vendors will inherit that boundary.

The timing is the operational question. A ruling before the administration retreats would make law. A retreat before ruling would preserve flexibility while admitting the designation could not survive review.

Here's What You Need to Know in 30 Seconds

The D.C. Circuit panel in Anthropic v. Department of War split visibly at oral argument on May 19. Henderson called the supply-chain-risk designation "spectacular overreach." Rao pressed Anthropic on model opacity and on whether the court should defer to executive national-security judgment. Katsas, the swing, pushed on both sides: model-side use restrictions as a narrower remedy, and on the rapid-evolution problem that makes any narrower remedy hard to verify. The ruling could go either way and Katsas is the vote that decides it. A ruling against DoW would do something larger than vindicate Anthropic: it would narrow the executive's ability to use procurement designations as a substitute for AI policy. A ruling for DoW would, conversely, ratify procurement-as-policy at exactly the moment the administration is leaning harder on it (the April Pentagon-Google deal, the pulled May security EO). Either way, the Henderson opinion (whether majority or dissent) will be cited going forward. The ruling is expected between late June and mid-August. The market is already pricing it both ways.

The Hawk Case: Procurement Is the Executive's Job

The hawk case is that procurement is one of the executive branch's few real levers. Congress has not defined military AI rules, but the Department still has to buy systems, protect classified networks, and decide which vendors can be trusted inside them.

From that view, a supply-chain-risk designation is not retaliation. It is a way to say that a vendor refusing mission-required terms cannot be treated as interchangeable with vendors willing to operate under them.

The hawk weakness is breadth. If every safety dispute becomes a supply-chain risk, procurement becomes a policy veto without the discipline of legislation.

The Reformer Case: Procurement Is Not the Same as Policy

The reformer accepts procurement authority and rejects its use as punishment. The executive may choose vendors. It may not create a de facto national rule by blacklisting a company because its safety terms obstruct a preferred military use.

The reformer also sees a separation-of-powers problem. If the court blesses this move, any future administration can make AI policy through contract eligibility, then dare Congress to catch up.

The reformer weakness is speed. Courts and Congress move slowly. Classified operations do not wait for a clean statute.

Where They Actually Agree

Both sides agree the panel split visibly and that the case is bigger than one vendor. Both also agree timing matters: the administration can still narrow the designation before an opinion forces the issue.

They disagree on whether that would be prudence or retreat. That distinction will shape how every AI vendor reads the next Pentagon negotiation.

Where They Don't (And Shouldn't Pretend To)

Procurement as policy. Hawks see an executive tool Congress left available. Reformers see an end-run around the rules Congress failed to write.

Supply-chain risk. Hawks use the label to capture mission reliability. Reformers read it as a sanctions-like designation without sanctions-like process.

Precedent. Hawks think an adverse ruling can be narrow. Reformers know agencies learn from boundaries, especially when the boundary arrives in a high-profile AI case.

Here's My Two Cents

The case is closer than the room sounded. Henderson gave Anthropic the headline, but Katsas owns the hinge: how far procurement discretion can travel before it becomes policy-making.

If the Department loses, the ruling will not merely vindicate Anthropic. It will narrow the executive branch's ability to use procurement status as a substitute for AI law.

My read: the procurement-as-policy era is closing either by opinion or by retreat. Congress can still write the military-AI lane, but the court is now drawing the first guardrail because Congress left the lane empty.
