Anthropic Long-Term Benefit Trust — Founded Date: May 2023

NoteThe claim specifies the founded date as 2023-05 (May 2023), which aligns with the source's explicit statement that the charter was amended to create Class T stock 'at the close of our Series C' in May 2023. The source confirms this timing through both the main text and the footnote reference to Series C. The public announcement occurred later (September 19, 2023), but the actual creation/founding of the trust structure occurred in May 2023 as claimed. The date precision matches (month-level equivalence).
