Will the US Department of War's 'Supply-Chain Risk to National Security' designation of Anthropic be in effect on 30 June 2026?

TL;DR

The named 10 U.S.C. § 3252 / DFARS designation is already blocked by the N.D. Cal. injunction, so I forecast only 16% that it is legally operative again at the 30 June deadline.

Context

As of 31 May 2026, the controlling fact is that Judge Rita Lin’s 26 March preliminary-injunction order expressly enjoins DoW and Secretary Hegseth from implementing, applying, or enforcing the 3 March letter and associated 10 U.S.C. § 3252 determination, and separately stays the effective date of that Supply Chain Designation under 5 U.S.C. § 705 (N.D. Cal. preliminary-injunction order). The N.D. Cal. docket was last retrieved on 29 May 2026 and shows no later order lifting that injunction; it instead shows administrative-record filings and a merits schedule running past the deadline (N.D. Cal. docket).

The confusion is that there are two related tracks. Judge Lin’s opinion says Anthropic received two 3 March letters: one citing 41 U.S.C. § 4713, challenged in the D.C. Circuit, and one citing 10 U.S.C. § 3252, challenged in N.D. Cal. (N.D. Cal. opinion). The D.C. Circuit’s 8 April order concerns the § 4713 determination, denied Anthropic an emergency stay, and expedited merits briefing and argument (D.C. Circuit 8 April order). I read the resolution text literally: the question asks about the § 3252 / DFARS designation, so the current legal state is NO unless the government gets the California injunction stayed, narrowed, dissolved, or bypassed by an equivalent new restriction before the deadline.

Evidence

The historical backbone is thin on exact supply-chain-risk designations, so I put weight on appellate timing and national-security procurement analogues. In FY2025 administrative-agency appeals, the D.C. Circuit median time from oral argument to last opinion or final order was 5.7 months, based on 62 argued administrative appeals; the national median was 3.0 months, based on 439 argued administrative appeals (U.S. Courts Table B-4C, 12 months ending 30 September 2025). Across all D.C. Circuit merits cases in FY2025, the oral-argument-to-final-order median was 5.4 months, based on 194 argued cases (U.S. Courts Table B-4, 12 months ending 30 September 2025). This case is much faster than normal: the D.C. Circuit set opening, response, and reply briefs for 22 April, 6 May, and 13 May, with oral argument on 19 May (D.C. Circuit 8 April order). It then ordered supplemental briefs, now due 4 June, leaving only 26 calendar days before the 30 June resolution deadline (Civil Rights Litigation Clearinghouse docket, last updated 31 May 2026).

National-security cases usually favor the government, but not always, and not always quickly. Kaspersky’s federal-product bans survived early challenges in 2018 (Nextgov, 30 May 2018). Huawei’s FCC national-security designation was upheld by the Fifth Circuit on 18 June 2021 (Huawei v. FCC). TikTok’s expedited D.C. Circuit challenge was argued on 16 September 2024 and decided on 6 December 2024, about 81 days later (TikTok D.C. Circuit docket). Ralls shows that due-process claims can win even in national-security review, but its D.C. Circuit relief came long after the challenged transaction actions (Ralls v. CFIUS). These analogues make a fast government win possible, but they do not make a fast removal of the separate California injunction likely.

The § 3252 / DFARS path is weak on the merits. Section 3252 requires a written national-security determination, consideration of less intrusive measures, congressional notice, and a supply-chain-risk theory tied to adversary sabotage, malicious unwanted function, or subversion of a covered national-security system (10 U.S.C. § 3252 text current to 30 May 2026). DFARS 239.73 implements that authority, requires a joint recommendation based on a risk assessment, and requires a written finding that less intrusive measures are not reasonably available (DFARS 239.73, change 11/10/2025, last updated 28 May 2026). Judge Lin found Anthropic likely to succeed on First Amendment retaliation, due process, and APA theories, and described the record as pretextual and inconsistent with the statutory supply-chain-risk concept (N.D. Cal. opinion).

The calendar is the main constraint on YES. N.D. Cal. ordered the defendants’ answer due 8 June, Anthropic’s summary-judgment motion due 10 June, the government’s opposition and cross-motion due 24 June, replies in July, and a hearing on 30 July (N.D. Cal. docket). The direct Ninth Circuit appeal of the California injunction was filed on 2 April, but the Ninth Circuit stayed appellate proceedings on 27 April pending D.C. Circuit No. 26-1049; any party may move to lift the stay, and appellants must seek relief within 21 days after the D.C. case is resolved if the stay remains in effect (Ninth Circuit docket via DocketAlarm). That means a pro-government D.C. decision would still require a second step before the § 3252 designation becomes operative again.

The oral-argument signal is mixed, but not good enough for a high YES forecast. AP reported that Judge Henderson saw no evidence supporting the Pentagon’s supply-chain-risk determination, while Judge Rao questioned the basis for second-guessing Hegseth’s risk judgment (AP, 19 May 2026). Axios reported that Judges Katsas and Rao pressed Anthropic on evolving AI models and model opacity, while Henderson sharply criticized the government; Axios also said the D.C. Circuit could rule within weeks but complex cases can take months (Axios, 19 May 2026). Meanwhile, DoW’s 1 May AI agreements with SpaceX, OpenAI, Google, NVIDIA, Reflection, Microsoft, AWS, and Oracle suggest the department is building around Anthropic rather than urgently needing to revive the enjoined § 3252 restriction before 30 June (DoW release, 1 May 2026).

My event tree starts from the current NO state. I estimate a 55% chance of a D.C. Circuit decision by 30 June, a 45% chance that a timely decision is government-favorable enough to help, and a 28% chance that such a decision leads to effective relief from the California injunction by the deadline. That core path contributes 6.9%. I add 3% for independent Ninth Circuit or Supreme Court emergency relief, 3% for a new or cleaned-up equivalent restriction that avoids the injunction, 1% for N.D. Cal. itself modifying the injunction or entering a final order before the July hearing, and 3% for residual resolution ambiguity around the still-live § 4713 track. Combining these as overlapping paths gives about 15.9% YES.

What's non-obvious

The obvious read is that the D.C. Circuit stay denial means the designation remains operative. That is true for the § 4713 track, but not for the § 3252 / DFARS designation named in the resolution text. The California order does not merely block the presidential Claude ban; it expressly blocks the March 3 § 3252 letter and associated determination, and stays their effective date (N.D. Cal. preliminary-injunction order).

The second hidden crux is that a D.C. Circuit government win would not automatically flip this question to YES. The D.C. order frames that case as a challenge to a § 4713 determination (D.C. Circuit 8 April order). The government would still need the N.D. Cal. injunction stayed, narrowed, or dissolved, or would need a new restriction that the resolver treats as equivalent. With supplemental briefs due 4 June and the deadline on 30 June, that is a narrow procedural window.

Limitations

The biggest limitation is docket visibility. I relied on public dockets and docket mirrors: the N.D. Cal. docket was last retrieved on 29 May, and the D.C. Circuit Clearinghouse docket was last updated on 31 May with entries through 22 May (N.D. Cal. docket; Civil Rights Litigation Clearinghouse docket). Sealed filings, PACER-only filings, or a very recent emergency application could move the probability quickly.

There is also real interpretation risk. If the resolver treats the still-operative § 4713 designation as the same underlying restriction, the YES probability would be much higher, roughly 60–70%. I do not use that reading because the resolution criteria name the March 3 § 3252 / DFARS designation and say a live injunction preventing DoW from treating Anthropic as designated resolves NO. I include a small residual term for this ambiguity rather than marking the question as needing clarification.
