Anthropic's seven founders are set to cash out about $250 million each in the company's IPO — without giving up any control. An amended prospectus filed on November 10, 2026, shows each of the seven selling 3,378,378 shares. At the $70–$78 offering price range, that works out to roughly $236 million to $264 million apiece, about $1.75 billion in total. Every dollar goes to the founders personally; Anthropic receives none of it.
The sale is a sliver — each founder keeps over 98%
The seven are CEO Dario Amodei, president Daniela Amodei, chief compute officer Tom Brown, chief science officer Jared Kaplan, chief architect Sam McCandlish, Jack Clark, and Christopher Olah. The filing shows each holding roughly 240.6 million to 244.2 million shares before the offering, so the sale covers only about 1.4% of each stake. Afterward, each will still hold about 3.2% of the Class A shares — roughly 22% combined. At the $74 midpoint of the price range, each remaining stake is worth about $18 billion.
Control is locked up in a single Class F share
What makes the cash-out look modest is the voting structure. The seven founders jointly control a founder LLC that holds a single Class F share, which carries a fixed 50.1% of the votes on most matters put to shareholders, cast as the majority of the founders decide. Each founder can still vote their own Class A shares separately. In other words, selling 1.4% changes neither who is in charge nor the balance among the founders.
The deal also has two hard constraints. First, the founders and holders of more than 0.5% of the company face a lock-up of up to 365 days, longer than the 180 days that apply to most shareholders. Second, all seven founders have previously pledged to give 80% of their personal Anthropic equity to philanthropic causes. Anthropic is expected to price the offering on November 18 and start trading on Nasdaq the next day under the ticker ANT.
