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 three current LTBT trustees (Shah, Fontaine, Cuéllar) and matches two names in the claim (Fontaine, Cuéllar). However, the source does NOT address: (1) the claim that Christiano and Robinson previously served and had AI safety/EA backgrounds, (2) the claim that two of five trustee 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 trustees with no mention of vacancies or historical composition. The claim's temporal marker 'as of 2026-03' cannot be verified against this source, which appears to be current but undated. The partial confirmation of current trustee names is insufficient to confirm the full claim about composition shifts and vacancies.
