On October 26, 2026, Anthropic announced that it filed a registration statement on Form S-1 with the U.S. Securities and Exchange Commission for a proposed initial public offering of its Class A common stock.
What to know
- Anthropic says it intends to list the shares on the Nasdaq Global Select Market under the symbol “ANT”.
- The number of shares and the price range have not been set.
- Anthropic names Goldman Sachs & Co. LLC and Morgan Stanley & Co. LLC as the contacts for the preliminary prospectus.
- The registration statement has been filed but is not yet effective, so the shares cannot be sold or bought yet. Anthropic says the announcement is not an offer to sell or a solicitation of an offer to buy.
