Anthropic Proposes IPO at $70–$78 a Share

Anthropic, PBC is proposing an initial public offering of 825 million Class A shares, with an estimated price range of $70 to $78 per share, according to its November 10, 2026, filing with the U.S. Securities and Exchange Commission. The submission is Amendment No. 2 to the company’s Form S-1 registration statement.

The prospectus identifies the offering terms as preliminary and subject to completion. The proposed range therefore does not represent a final offering price.

Of the shares proposed for sale, 801,351,354 would come from Anthropic and 23,648,646 from existing shareholders, according to the filing. Both portions form part of the proposed 825 million-share offering.

The Associated Press put the valuation implied by the proposed offering at approximately $1.3 trillion. That figure is the news agency’s estimate, rather than a finalized valuation set out in the SEC filing.

Anthropic announced that the roadshow for its proposed Class A share sale began on November 10, 2026. According to the prospectus, the company has submitted an application for the shares to trade with the ticker ANT on the Nasdaq Global Select Market. The document also states that no public trading market existed for those shares before the offering.

The company’s earlier announcement, dated June 1, 2026, concerned its confidential submission of a draft Form S-1. Anthropic said at that time that neither the share count nor the proposed offering price had been determined.
