Anthropic’s IPO filing puts a proposed Nasdaq listing on the public record, but its shares are not yet cleared for sale. Anthropic, PBC filed a Form S-1 with the U.S. Securities and Exchange Commission on October 26, 2026, for an initial public offering of its Class A common stock.
The company intends to trade on the Nasdaq Global Select Market under the ticker ANT. The public filing follows a confidential submission to the SEC in June.
The planned offering concerns Class A common stock. Anthropic describes the transaction as a proposed IPO and says its registration statement has not yet become effective.
Anthropic’s IPO filing sets out the offering process
Anthropic’s IPO filing does not allow sales to begin: the securities cannot be sold, and offers to buy cannot be accepted, until the registration statement becomes effective. That restriction separates the filing from the sale of shares.
The offering will proceed only through a prospectus. Anthropic identifies Goldman Sachs & Co. LLC and Morgan Stanley & Co. LLC as contacts for obtaining copies of the preliminary prospectus once it becomes available. Goldman Sachs and Morgan Stanley are also the lead underwriters.
Anthropic says its announcement is neither an offer to sell the securities nor a solicitation to buy them. It also states that sales cannot take place in any state or jurisdiction where they would be unlawful before registration or qualification under the applicable securities laws.
