Criterion: the appearance of a publicly available registration Form S-1 (or S-1/A) for Anthropic PBC in the SEC EDGAR database with a filing date no later than October 31, 2026 (23:59 UTC). "Yes" — if such a document is published on EDGAR by this deadline; "No" — if it is not. Confidential draft submissions (DRS) do not count. Benchmark: Anthropic filed a confidential draft on June 1, 2026, and media reports indicate that the IPO is postponed to November 2026. Source: the company page on sec.gov (EDGAR). Marginal cases: the date is considered to be the Filing Date in EDGAR; if there is a delay in display, a document published on EDGAR within 48 hours after the deadline with a Filing Date no later than 10/31/2026 is taken into account.
