Hegseth Formally Denies Anthropic Appeal to Overturn Supply Chain Risk Designation

BLUFClosing internal review forces a DC Circuit ruling that will bound executive authority to designate domestic AI firms as supply-chain risks, with an emergency stay before July 5 unlikely at high confidence.

Hegseth denied Anthropic's reconsideration request in a June 3 decision, citing "pre-deployment risks," "loss of trust," and "other risk factors" as sufficient grounds to sustain the designation 1. The Pentagon notified the DC Circuit on Thursday, asking the three-judge panel to proceed now that internal review is closed 1. Hegseth's decision specified that the designation rested on pre-deployment concerns rather than any belief that Anthropic could alter Claude after deployment; Anthropic said the original determination was based on a misunderstanding 12. Anthropic has sought an emergency stay in the DC appeals case; its public statement identifies the underlying dispute as two use-policy exceptions it sought, barring mass domestic surveillance and fully autonomous weapons 34.

Analysis
Hegseth's June 3 reformulation shifted the designation's legal basis from post-deployment manipulation to pre-deployment trust loss, closing the internal review track and narrowing the factual record without resolving whether DoD holds statutory authority to designate domestic AI firms as supply-chain risks. That question now belongs to the DC Circuit. An emergency stay is unlikely before July 5, 2026. High confidence reflects the panel's oral-argument posture and convergent signaling from both Trump-appointed judges during March proceedings. The designation may instead function as negotiating leverage. Anthropic's prior concession on one use-policy exception suggests further capitulation could prompt Pentagon reversal before any ruling issues. DoD contractors using Claude for military work should begin transition planning now if the stay is denied, and can defer that decision if it is granted.
