When Is the Anthropic IPO? What the S-1 Reveals, the Steps to Listing, and Whether You Can Buy
On October 26, 2026 (US time), Anthropic filed a Form S-1 for an initial public offering (IPO) with the US Securities and Exchange Commission (SEC) and applied to list on the Nasdaq Global Select Market under the ticker "ANT". The listing date, share count, price range and amount to be raised have not been set. Drawing on the original S-1, this article covers revenue ($4.585 billion in 2025 and $16.286 billion in the first half of 2026) and what is behind the losses, the five share classes (A, N, T, F and E) and their voting rights, how the Long-Term Benefit Trust (LTBT) and the public benefit corporation (PBC) structure work, the stakes held by Amazon and Google, the use of proceeds and the risk factors. It then walks through the steps to listing based on the SEC's guidance, whether and how you can buy the shares (checked October 27, 2026), and what it means for Claude users. It is not investment advice, and it is updated whenever new information comes out.
