Question
Will the US Department of War supply-chain risk designation against Anthropic be formally vacated before May 21, 2027?
The resolution criteria for this outcome are exceptionally strict: the Department of War's supply-chain risk designation must be formally vacated, rescinded, or permanently set aside before May 21, 2027. Interim relief, such as the preliminary injunction granted by Judge Rita Lin in the Northern District of California assets.bwbx.io, explicitly does not qualify en.wikipedia.orgjoneswalker.com. While Anthropic has demonstrated meaningful strength on the merits, translating that into a final, counting vacatur within the remaining 11-month window faces steep procedural and appellate headwinds.
The primary avenue for a qualifying resolution is the direct challenge to the §4713 FASCSA designation currently before the D.C. Circuit. During the May 19, 2026 oral argument, the panel appeared skeptical of the government's position. Judge Henderson pressed the lack of evidence regarding malicious manipulation or sabotage, while Judge Rao questioned whether the Department's urgency rationale would swallow statutory safeguards courtlistener.com. However, an adverse view of the government's case does not guarantee a formal vacatur. The court could resolve the case on jurisdictional grounds, as hinted by Judge Katsas courtlistener.com. More importantly, in Administrative Procedure Act challenges involving military and national security equities, the D.C. Circuit frequently applies the Allied-Signal test to order a "remand without vacatur" to avoid disruptive consequences. This would force the agency to correct procedural defects but leave the designation technically in place, failing to trigger a positive resolution.
Voluntary withdrawal or settlement also appears unlikely in the near term. Although a broader settlement tied to Anthropic's concurrent export-control negotiations or impending IPO remains a tail possibility, the Department of War formally denied Anthropic's reconsideration request on June 3/4, demonstrating administrative entrenchment courtlistener.compolitico.com.
Even if the D.C. Circuit panel orders a clean vacatur, the timeline poses a significant finality risk. The government has strong incentives to preserve its national-security procurement tools and would likely seek en banc or Supreme Court review. A stay of the mandate pending these appeals could easily push the final, surviving vacatur past the May 2027 deadline. Overall, while Anthropic's substantive case is strong, the demanding requirement for a final, formal vacatur—coupled with the high risk of a remand without vacatur and protracted appeals—constrains the likelihood of this outcome.
