Anthropic submits IPO registration to the SEC, plans Nasdaq listing as ANT

On 26 October 2026 Anthropic said it had submitted a registration statement on Form S-1 to the US Securities and Exchange Commission. The filing covers a proposed initial public offering of the company's Class A common stock. Anthropic, which is organized as a public benefit corporation, intends to have the shares listed on the Nasdaq Global Select Market with the ticker symbol ANT.

The announcement does not give the size of the offering: how many shares will be sold and the price range have not been decided yet. The offer will be made only through a prospectus, and Goldman Sachs & Co. LLC and Morgan Stanley & Co. LLC are named as the banks that will provide copies of the preliminary prospectus once it is available.

The registration statement has not yet become effective. Until it does, the shares cannot be sold and no offers to buy them can be accepted, and Anthropic states that the announcement itself is neither an offer to sell nor a solicitation to buy the securities.
