QuoteShort answer: there is no official Anthropic S-1 prospectus PDF yet. As of October 13, 2026, Anthropic has only confidentially submitted a draft Form S-1 to the SEC (announced June 1, 2026), and no public S-1 from Anthropic, PBC appears on SEC EDGAR. The numbers going around come from a draft prospectus Reuters saw on September 28: about $4.6 billion of 2025 revenue, a $42 billion net loss and $11.5 billion of revenue in Q2 2026. Reports say Anthropic is aiming for a Nasdaq listing as soon as mid-November, but no IPO date, ticker or price range is confirmed.
