Anthropic, the artificial intelligence company behind Claude, filed for an initial public offering with the U.S. Securities and Exchange Commission on October 26, 2026, seeking to list its Class A common shares on the Nasdaq Global Select Market under the ticker symbol ANT.
The company confirmed the proposed listing in its official announcement, while its SEC registration filing identifies ANT as the proposed trading symbol. The filing marks a significant step toward public ownership of Anthropic, which develops the Claude family of AI models. It does not mean the company has completed its IPO or begun trading.
According to the SEC filing record, the registration statement was accepted on October 26. Anthropic previously submitted confidential draft registration materials, making the publicly filed Form S-1 the latest formal development in its listing process.
The company has not determined how many Class A shares it will offer or the proposed price range. Consequently, the filing does not establish the amount Anthropic expects to raise or the valuation investors will assign to the offering. Goldman Sachs and Morgan Stanley are identified in Anthropic’s announcement as contacts for obtaining the preliminary prospectus when available.
The IPO remains subject to the registration process. Anthropic stated that its registration statement has not become effective and that the securities cannot be sold before effectiveness.
For investors considering exposure to the AI sector, the next substantive developments will be the disclosure of offering terms, any amendments to the registration statement and confirmation of a trading date. Until those details are announced, ANT remains a proposed Nasdaq symbol rather than an actively trading Anthropic stock.
