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' timeframe), and (3) the additional context is verified—he is described as President of Carnegie Endowment for International Peace and as 'a Justice of the Supreme Court of California' (former). The source is the official Anthropic announcement of this exact appointment.
