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 prior trustee composition (Christiano, Robinson) or the shift from AI safety/EA backgrounds to national security expertise, (2) whether two of five seats remain vacant as of March 2026, or (3) the total number of trustee seats. The source lists only three current trustees (Shah, Fontaine, Cuéllar) but does not explicitly state the total seat count or vacancy status. The claim's temporal marker 'as of 2026-03' cannot be verified against a source that does not include a date stamp. The partial confirmation of Fontaine and Cuéllar's presence, combined with unverifiable claims about prior composition and vacancies, yields a 'partial' verdict.
