Anthropic Long-Term Benefit Trust — Notable For: Trustee composition shifted from AI safety/EA backgrounds (Christiano, Robinson) to national security and global governance expertise (Fontaine, Cuéllar). Two of five trustee seats remain vacant as of March 2026.

NoteThe source confirms that Richard Fontaine and Mariano-Florentino Cuéllar are current LTBT trustees (matching the claim's assertion about their appointment). However, the source does NOT address: (1) the claim that Christiano and Robinson previously held trustee seats with AI safety/EA backgrounds, (2) whether two of five seats remain vacant as of March 2026, or (3) the characterization of the shift from AI safety/EA to national security/global governance expertise. The source lists only three current trustees (Shah, Fontaine, Cuéllar) with no information about total seat count, vacancy status, or historical composition. The claim's temporal marker 'as of 2026-03' cannot be verified against a source with no date stamp. The partial confirmation of Fontaine and Cuéllar's current roles, combined with unverifiable claims about prior trustees and vacant seats, yields a 'partial' verdict.
