AI Firm Anthropic Files S-1 with U.S. SEC for Proposed Nasdaq IPO
Anthropic formally applied for an IPO, planning to list Class A common stock on Nasdaq under symbol ANT, with share count and price range still undetermined.
Artificial intelligence company Anthropic filed a Form S-1 registration statement with the U.S. Securities and Exchange Commission (SEC) on October 26, 2026, initiating its initial public offering (IPO) process. The company intends to list its Class A common stock on the Nasdaq Global Select Market under the ticker symbol “ANT.”
According to Anthropic’s official announcement, the number of shares to be offered and the price range for the proposed offering have not yet been determined. The registration statement has been filed but has not yet become effective; therefore, securities may not be sold, nor may offers to buy be accepted, prior to effectiveness. Underwriters include Goldman Sachs & Co. LLC and Morgan Stanley & Co. LLC.
This move marks a significant development in AI industry capital markets. As one of the leading large language model developers, Anthropic’s listing process will provide important valuation references and exit path signals for private AI companies. However, investors should note that current disclosures only confirm the intent to list and regulatory filing status; specific financial terms, dilution effects, and final pricing remain unknown.
