Personnel: Jason Matheny at Anthropic Long-Term Benefit Trust (Trustee)

Verdictcontradicted95%
1 check · 4/14/2026

The record claims Jason Matheny held the role of Trustee at the Anthropic Long-Term Benefit Trust with both startDate and endDate of 2023. While the source confirms he was initially appointed as a Trustee in 2023, it explicitly states he stepped down in December 2023. The record's endDate of 2023 is technically correct (he did leave in 2023), but the record presents this as if he held the role throughout 2023 without indicating he stepped down mid-year. More critically, the record does not reflect his departure status. The source directly contradicts the implication that he remained a Trustee beyond December 2023, making the record incomplete/outdated as presented. Since the record shows only '2023' for both dates without indicating the mid-year departure, this is contradicted by the source's explicit statement of his stepping down.
