Anthropic Long-Term Benefit Trust — Description: Delaware purpose trust established in 2023 to ensure Anthropic responsibly develops AI for humanity's long-term benefit. Holds Class T Common Stock with negligible economic value but phased governance power over Anthropic's board of directors. Trustees are financially disinterested.

NoteThe claim is largely confirmed by the source text. All major elements are present: Delaware purpose trust (confirmed: 'organized as a "purpose trust" under the common law of Delaware'), 2023 establishment (confirmed: 'Sep 19, 2023'), responsible AI development for humanity's benefit (confirmed: 'purpose that is the same as that of Anthropic'), Class T Common Stock (confirmed), phased governance power (confirmed: 'phase in according to time- and funding-based milestones; in any event, the Trust will elect a majority of the board within 4 years'), and financially disinterested trustees (confirmed: 'arrangements are designed to insulate the Trustees from financial interest'). However, the source does not explicitly characterize the Class T stock as having 'negligible economic value' — this detail is not addressed in the provided excerpt. The claim's date reference '(as of 2026-03)' cannot be verified from a 2023 source document, but this is a temporal metadata issue rather than a factual contradiction about the trust's description itself.
