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

I forecast NO: the 10 U.S.C. § 3252 / DFARS designation is already blocked, and the government has a short, procedurally narrow path to revive it by 30 June 2026.

Context

I treat the target as the March 3, 2026 10 U.S.C. § 3252 / DFARS designation, not the parallel 41 U.S.C. § 4713 determination in the D.C. Circuit. The reason is that the resolution criteria name § 3252 / DFARS, and the Northern District of California preliminary-injunction order expressly enjoins DoW and Secretary Hegseth from implementing or enforcing the February 27 Hegseth Directive and the March 3 letter formalizing the designation under § 3252; it also stays the effective date under 5 U.S.C. § 705 (N.D. Cal. Doc. 135). (docs.justia.com)

The current litigation posture is therefore not “designation in force unless Anthropic wins.” It is “designation blocked unless the government gets relief.” The D.C. Circuit case remains active after May 19 oral argument and June 4 supplemental briefs, but it is the § 4713 track; the Ninth Circuit appeal from Judge Lin’s injunction was stayed on April 27 pending the D.C. Circuit case, with either party allowed to move to lift that stay (D.C. Circuit docket; Ninth Circuit docket). (clearinghouse.net)

Evidence

The historical backbone is timing. Federal appellate merits decisions usually take months after argument, not weeks. For the D.C. Circuit in the 12 months ending September 30, 2024, the official judiciary table reports an argument-to-final-opinion-or-order median of roughly five months for argued terminations, with N in the low hundreds for the circuit (U.S. Courts Table B-4, FY2024). (uscourts.gov) This case is faster than the base rate because the April 8 D.C. Circuit order granted expedition and set May 19 argument, but the panel then requested supplemental briefs and extended them to June 4, leaving only 26 days before the June 30 deadline (D.C. Circuit docket). (clearinghouse.net)

The merits are mixed, but not the main driver. Section 3252 and DFARS subpart 239.73 define supply-chain risk around an adversary sabotaging, subverting, surveilling, denying, disrupting, or degrading covered national-security systems; they also require written determinations and consideration of less intrusive measures (10 U.S.C. § 3252; DFARS subpart 239.73). (uscode.house.gov) Judge Lin found Anthropic likely to succeed on statutory, APA, due-process, and First Amendment theories, and the operative injunction blocks the § 3252 designation pending final resolution or further order (N.D. Cal. opinion; N.D. Cal. Doc. 135). (law.justia.com) The D.C. Circuit panel denied Anthropic emergency relief on April 8 because the equities favored the government during an active military conflict, but it also called the issues novel and difficult and expedited merits review (D.C. Circuit docket summary). (clearinghouse.net)

The ordinary district-court path points past the deadline. Judge Lin’s April 23 schedule set the government’s answer for June 8, Anthropic’s summary-judgment motion for June 10, the government’s opposition and cross-motion for June 24, replies for July 8 and July 15, and a hearing for July 30 (N.D. Cal. scheduling order). (docketalarm.com) That makes a final N.D. Cal. merits ruling before June 30 unlikely. The Ninth Circuit path is also slow unless the government changes course: the government moved to stay its own appeal, the Ninth Circuit granted that stay on April 27, and the order says appellants must seek relief within 21 days after the D.C. Circuit resolves No. 26-1049 if the stay remains in effect (Ninth Circuit docket). (docketalarm.com)

I model the YES paths this way. A direct Ninth Circuit or Supreme Court stay of Judge Lin’s § 3252 injunction before any D.C. merits ruling is about 4%, because the government has let the injunction sit while its appeal is stayed. A D.C. Circuit ruling before June 30, favorable to the government, followed by fast relief from the N.D. Cal. injunction is about 8%: I use 50% for a D.C. ruling by the deadline, 55% for a government-favorable or threshold disposition, and 30% that this converts into operative § 3252 relief before the deadline. A new or re-papered equivalent designation that survives immediate challenge is about 4%. N.D. Cal. modification, Supreme Court surprise, or docket-lag surprises add about 3%. Combining those overlapping paths gives roughly:

$$1-(1-.04)(1-.08)(1-.04)(1-.03) \approx 18\%.$$

The non-court signals do not move me much toward YES. Reuters reported on June 5 that White House-Anthropic relations have thawed, but also that the Defense Department was still vigorously defending the lawsuit and that both sides were still arguing over the designation on June 4 (Reuters via Investing.com). (m.investing.com) MLex reported that DoD formally denied Anthropic’s reconsideration request on June 3, which cuts against voluntary rescission but does not by itself revive the enjoined § 3252 designation (MLex summary). (mlex.com) DoW also announced May 1 agreements with eight other AI providers for classified networks, which lowers the operational need to force emergency revival of the blocked Anthropic designation before June 30 (DoW release).

What's non-obvious

The non-obvious fact is that the client’s background description is wrong on the controlling district-court order. Judge Lin did not merely enjoin the separate presidential Claude phase-out. The preliminary-injunction order names the March 3 § 3252 letter and associated determination, blocks their implementation and enforcement, and stays their effective date (N.D. Cal. Doc. 135). (docs.justia.com) Under the resolution criteria’s own language, that is already a NO posture unless the injunction is lifted or bypassed by a qualifying new equivalent action.

Most press coverage collapses the § 4713 and § 3252 tracks into one “blacklist.” That is why headlines can say the D.C. Circuit left the Pentagon label in place while the strict § 3252 / DFARS designation named in this question is still blocked. The D.C. Circuit argument looked divided: Judge Henderson was sharply skeptical of DoW’s evidence, while Judge Rao sounded more receptive to national-security deference (Yale Journal on Regulation; AP). (yalejreg.com) A government win there would matter, but it would still need to be translated into relief from the N.D. Cal. injunction in a short window.

Limitations

I could not inspect sealed or classified filings, and national-security procurement disputes can move through restricted records. I also could not read the full text of the June 3 reconsideration denial, only public docket descriptions and secondary reporting (D.C. Circuit docket; MLex summary). (clearinghouse.net) A sealed emergency motion or a rapid unpublished order could change the answer quickly.

The largest interpretive risk is the parallel § 4713 determination. If the resolver treats that existing § 4713 action as a “substantively equivalent” designation that keeps the underlying restriction in effect despite the § 3252 injunction, the YES probability would be much higher, roughly 60-70%. I do not use that reading because the title and resolution criteria specifically target the March 3 § 3252 / DFARS designation and say an injunction preventing DoW from treating Anthropic as a designated supply-chain risk resolves NO (N.D. Cal. Doc. 135; D.C. Circuit docket). (docs.justia.com)
