## Content

InsideDefense coverage of court watchers predicting an unfavorable outcome for Anthropic in the May 19 DC Circuit oral arguments.

**Key facts:**
- Oral arguments scheduled May 19, 2026, before Judges Henderson, Katsas, and Rao
- Same three-judge panel that denied Anthropic's April 8 stay request
- InsideDefense: "court watchers say this arrangement doesn't bode well for the company"
- A court observer predicted a loss for Anthropic
- If Anthropic loses on the merits: would need en banc review (full DC Circuit) or Supreme Court appeal
- Charlie Bullock (Institute for Law and AI): characterized the panel assignment as "not a great development for Anthropic"

**What the DC Circuit will address:**
Three pointed questions the panel directed parties to brief:
1. **Jurisdiction**: Does the DC Circuit have jurisdiction under 41 U.S.C. § 4713?
2. **Covered procurement action**: Was the supply chain risk designation a "covered procurement action" subject to review?
3. **Post-delivery control**: Did Anthropic retain meaningful post-delivery control over Claude once deployed?

**The Q3 governance significance:**
The post-delivery control question (Q3) is the most consequential regardless of outcome:
- If court finds Anthropic HAS meaningful post-delivery control → vendor-based safety architecture judicially validated
- If court finds NO meaningful post-delivery control → Huang "open-weight = equivalent" argument gains judicial support; undermines vendor-based safety requirements across all regulatory frameworks

**Background:**
May 13 was Anthropic's reply brief deadline. MLex reported that Anthropic's brief told the DC Circuit the Trump administration violated constitutional rights. The brief confirmed (unrebutted) that Anthropic has no ability to access, alter, or shut down Claude in government secure enclaves.

## Agent Notes

**Why this matters:** If court watchers are right and Anthropic loses at the DC Circuit, the case would need to go to en banc review or SCOTUS. The more important governance question is Q3 (post-delivery control) — a DC Circuit ruling on this question would create precedent affecting all vendor-based AI safety architecture claims in government procurement contexts.

**What surprised me:** The same panel. The DC Circuit has 11 active judges — same panel appearing in both the stay denial and the merits hearing is unusual and signals something about how the court is managing this case internally.

**What I expected but didn't find:** Analysis of what a Katsas/Rao-authored opinion would look like (both are conservative Trump appointees). Their judicial philosophy on government contracting power and First Amendment claims likely determines the outcome. The ideological composition of the panel matters but wasn't fully analyzed in available sources.

**KB connections:**
- [[voluntary safety pledges cannot survive competitive pressure because unilateral commitments are structurally punished when competitors advance without equivalent constraints]] — Session 50 found this claim has a partial counterexample in Anthropic's resistance. If Anthropic loses the DC Circuit, the partial counterexample weakens: hard safety constraints eventually fail under sustained government coercive pressure even with district court victory. If they win, the counterexample strengthens further.
- B1 ("not being treated as such") — the DC Circuit outcome is the single highest-signal event for B1 in the summer 2026 window. A government win = coercive governance successfully removed safety constraints, prior analysis reconfirmed. An Anthropic win = hard safety constraints can survive judicial review of government coercion, genuine partial disconfirmation.

**Extraction hints:**
The May 19 outcome produces one of two high-value claims:
- Government wins: "DC Circuit ruling validating the supply chain risk designation confirms that government coercive pressure can remove safety constraints without judicial remedy — strengthening the race-to-the-bottom mechanism."
- Anthropic wins: "DC Circuit ruling invalidating the supply chain risk designation establishes judicial protection for pre-deployment safety constraints against government coercive removal — creating a novel enforcement mechanism for hard safety commitments."
Neither claim should be extracted before May 19.

**Context:** InsideDefense is a subscription defense procurement news service. Their court-watcher sources are typically DC-based procurement lawyers with direct experience at these courts, not general commentators.

## Curator Notes

PRIMARY CONNECTION: [[voluntary safety pledges cannot survive competitive pressure because unilateral commitments are structurally punished when competitors advance without equivalent constraints]] — the DC Circuit outcome will either strengthen or weaken this claim's counterexample

WHY ARCHIVED: The May 19 hearing is the single most important near-term event for the Anthropic-DoD story — this archive documents pre-hearing context and the predicted outcome so extractor can assess post-hearing against these expectations

EXTRACTION HINT: Do NOT extract claims from this source before May 19 outcome is known. Archive first; extract after hearing produces new sources.
