Will the US Department of War supply-chain risk designation against Anthropic be formally vacated before May 21, 2027? Interim relief such as preliminary injunctions does not qualify; the designation must be formally vacated, rescinded, or permanently set aside.

probability: 30%

rationale:

Two Distinct Designations The outcome hinges on the fact that the Department of War made two separate supply-chain risk designations against Anthropic: one under 10 U.S.C. 3252 and another under 41 U.S.C. 4713 (FASCSA). The fundamental uncertainty driving this estimate is whether the permanent vacatur of the Section 3252 designation satisfies the requirement, or whether the ongoing and actively enforced Section 4713 designation means the overarching exclusion must be lifted.

The Section 3252 Vacatur On August 27, 2026, a California district court entered a final judgment that formally vacated and permanently enjoined the Section 3252 designation An AI Model Retaliation Ruling and the Designation It ... https://www.congress.gov/crs_external_products/IF/PDF/IF13217/IF13217.4.pdf. The government has until roughly October 26 to appeal this final judgment, and no appeal has been reported to date An AI Model Retaliation Ruling and the Designation It ... Anthropic–United States Department of Defense dispute. If interpreted strictly on its text, the permanent vacatur of this specific statutory designation presents a strong technical case that the condition has already been met.

The Active Section 4713 (FASCSA) Designation On the other track, the FASCSA designation remains fully in effect. On September 25, a 2-1 D.C. Circuit panel upheld this designation, and the Pentagon continues to actively enforce Anthropic's exclusion Pentagon stops using Anthropic AI tools after blacklisting ... D.C.

Anthropic filed a petition for rehearing en banc on October 13, arguing that the government skipped required notice and that the ruling conflicts with the California court's findings Why Anthropic Is Asking for a Rehearing En Banc https://qz.com/anthropic-pentagon-blacklist-appeals-court-rehearing-101426. However, the D.C. Circuit rarely grants discretionary en banc review. Even if granted, completing full en banc or Supreme Court proceedings and achieving a final vacatur before May 21, 2027, is highly improbable given the tight timeline. This limited likelihood of timely legal relief also anchors the remote chances of Anthropic securing a major defense contract in the same timeframe.

Prospects for Political Relief There remains a distinct possibility of a voluntary rescission or political settlement. President Trump hosted Anthropic CEO Dario Amodei at the White House in late September and met with him again in early October Trump had private dinner with Anthropic CEO Dario Amodei Trump dines with Anthropic CEO Dario Amodei after ....

Conclusion The 30% probability reflects a balance of these diverging realities. On one hand, the operational reality is that Anthropic remains effectively banned under FASCSA, and achieving judicial relief or a political settlement on that track before May 2027 faces steep odds. On the other hand, there is a very real possibility that the August 27 permanent vacatur of the parallel Section 3252 designation will be deemed sufficient to meet the strict textual requirements of a formal vacatur.
