Anthropic Long-Term Benefit Trust — Headquarters: San Francisco, CA

NoteThe claim is about the 'Anthropic Long-Term Benefit Trust' as a distinct entity with its own headquarters. The source is about Anthropic PBC (the company). While the source confirms the Long-Term Benefit Trust exists and names its trustees, it does not provide the headquarters location of the trust itself. The source discusses Anthropic's governance structure but does not address where the trust is headquartered. This is a subject mismatch: the trust is a separate legal entity from the company, even though it is affiliated with Anthropic.
