Anthropic, PBC confidentially submitted a draft Form S-1 to the SEC on June 1, 2026.
- A confidential draft is not visible on EDGAR.
- Before a roadshow the company must "flip" it public (the prospectus has to be public at least 15 days before the roadshow starts).
- Reuters has moved this date several times: "after Labor Day", then "late September", then an IPO launch "mid-October at the earliest", and on 9/28 a listing expected after the Nov 3 midterms.
- As of 9/29, EDGAR shows no public Anthropic S-1.
- This market asks WHICH WEEK the public S-1 appears.
