Anthropic filed its S-1 prospectus publicly on October 26, outlining a planned Nasdaq listing under ANT and reporting first-half financial results.
Anthropic publicly filed its S-1 prospectus with the Securities and Exchange Commission on October 26, 2026, detailing plans to list on Nasdaq under the ticker symbol ANT. The filing follows a confidential submission in June, and makes the company’s stated plans and financial disclosures public as it prepares for a potential initial public offering.
The prospectus reports that Anthropic recorded $16.3 billion in revenue and an $80.7 billion net loss in the first half of 2026. Those figures are reported in the filing and do not, by themselves, explain the sources or timing of the loss. The document also sets out risks for investors and describes how the company views the opportunities and dangers associated with AI.
Anthropic’s filing says the company aims to pursue AI’s potential benefits while addressing risks, and asks investors to consider its approach to building and operating the business, including how it may differ from a company focused solely on maximizing profit. These are the company’s stated positions in its prospectus, not a guarantee of outcomes.
The S-1 marks a public disclosure step in Anthropic’s IPO preparations; the company says it plans a Nasdaq listing, but the filing does not mean that a listing has already occurred. The prospectus provides investors with financial and company information as they assess the planned offering.
