Anthropic’s seven co-founders each plan to sell 3,378,378 shares in its planned initial public offering, according to the company’s S-1 filing. Each would receive just under $250 million at the midpoint of the proposed price range. The offering could value Anthropic at $1.4 trillion.

The company has proposed pricing shares between $70 and $78, with a midpoint of $74. Each founder’s proceeds would be just over $236 million at the bottom of that range or just under $264 million at the top.

The filing says each founder would hold about 3.2% of outstanding Class A stock following the sale, giving them roughly 22% collectively. Those figures do not represent their ownership of Anthropic’s total equity: other investors, including Amazon and Google, own nonvoting Class N stock.

Each founder will also receive a single Class F share with supervoting rights. Together, they will retain 51.1% of voting power, with no individual founder holding significantly more stock or votes than the others.

Two directors have signaled interest in purchasing shares. Reed Hastings wants to invest $300 million through his donor-advised fund, while Christopher Liddell wants to purchase $3 million worth, according to the filing.

The founders are CEO Dario Amodei; president and board chair Daniela Amodei; chief compute officer Tom Brown; public benefit head Jack Clark; chief science officer Jared Kaplan; chief architect Sam McCandlish; and interpretability research lead Christopher Olah. They left OpenAI and established Anthropic in 2021 after disagreements with its leadership over AI development.
