Anthropic Founders to Each Cash Out About $250M in IPO

Preparing for an IPO that has drawn significant investor interest, Anthropic has disclosed the stock sale plans of its seven founders in its S-1 filing.

In Anthropic's ongoing IPO preparations, each of the company's seven founders will sell 3,378,378 shares. Based on the midpoint price of $74 per share, each founder is expected to generate approximately $250 million in proceeds. According to the initial price range of $70 to $78, this amount equates to over $236 million on the low end and under $264 million on the high end.

Company board member Reed Hastings expressed his intent to purchase $300 million worth of shares through a donor-advised fund, while Christopher Liddell indicated he wants to buy $3 million worth. Following the sale, each founder will hold approximately 3.2% of the total Class A shares. While other partners such as Amazon and Google hold non-voting Class N shares, the founders will collectively retain 51.1% of the voting power, maintaining control of the company.

Founded in 2021 by Dario Amodei, Daniela Amodei, Tom Brown, Jack Clark, Jared Kaplan, Sam McCandlish, and Christopher Olah—who departed OpenAI due to leadership disputes—Anthropic is known for its focus on artificial intelligence safety.
