On October 26, 2026, Anthropic, PBC announced that it has filed a Form S‑1 registration statement with the U.S. Securities and Exchange Commission (SEC) in connection with a proposed initial public offering of its Class A common stock.
The company said it intends to list its Class A common stock on the Nasdaq Global Select Market under the ticker symbol “ANT.” The number of Class A shares to be offered and the proposed price range have not yet been determined.
The proposed offering will be made only by means of a prospectus; preliminary prospectuses, when available, may be obtained from the following underwriters:
- Goldman Sachs & Co. LLC, Prospectus Department, 200 West Street, New York, NY 10282; telephone: (866) 471-2526; email: prospectus-ny@ny.email.gs.com
- Morgan Stanley & Co. LLC, Prospectus Department, 180 Varick Street, 2nd Floor, New York, NY 10014
A registration statement relating to these securities has been filed with the SEC but has not yet become effective. Accordingly, the securities may not be sold, nor may offers to buy be accepted, prior to the time the registration statement becomes effective. Today’s announcement does not constitute an offer to sell or the solicitation of an offer to buy these securities, and there will be no sale in any state or jurisdiction where such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of that state or jurisdiction.
Why this matters
Filing a Form S‑1 starts the regulated disclosure process required for a U.S. IPO and signals that Anthropic is moving toward a public listing. Detailed financial and business information will be released in the prospectus and subsequent filings; the exact share count and pricing will be disclosed later and depend on the SEC review and market conditions.
