Anthropic chose to incorporate as a public benefit corporation when it was founded.

Judge as of 2022-03-04. True if Anthropic was incorporated as a public benefit corporation at its founding (2021), shown by state incorporation records (e.g. Delaware PBC filing) or official company statements. Mostly true if it became a PBC at or within a few months of founding with a minor timing detail differing. Mostly false if it was a PBC by 2022 but converted to that status well after founding. False if Anthropic was not a public benefit corporation at that time.

   “The S-1 says Anthropic was incorporated as a Delaware PBC in January 2021.”

E3, an independent timeline summarising Anthropic's S-1, reports that Anthropic was incorporated as a Delaware PBC in January 2021, which is its founding period. E2, Anthropic's own 2023 announcement, confirms it is a Delaware Public Benefit Corporation. E1 quotes the corporation's stated specific public benefit, which is consistent with PBC status. Together these show Anthropic was a PBC from founding, which supports the claim as of 2022-03-04.
