Anthropic Long-Term Benefit Trust — key-event: Mariano-Florentino Cuéllar appointed as trustee

NoteThe source directly confirms all three components of the claim: (1) Mariano-Florentino Cuéllar was appointed to the Long-Term Benefit Trust, (2) the appointment occurred in January 2026 (matching the 'as of 2026-01' date), and (3) the additional context is verified—he is President of Carnegie Endowment and a former CA Supreme Court Justice. The source text explicitly states: 'Jan 21, 2026 Anthropic's Long-Term Benefit Trust announced the appointment of Mariano-Florentino (Tino) Cuéllar as a new member of the Trust' and confirms his roles as 'Justice of the Supreme Court of California' and 'President of the Carnegie Endowment for International Peace.'
