Anthropic, the AI startup, is set to make a major move with an anticipated IPO valued at $1.4 trillion. As part of this IPO, each of the company's seven co-founders plans to sell 3,378,378 shares each. With an initial price range of $70 to $78 per share, at the midpoint it's projected that each founder will net approximately $250 million, ranging from over $236 million at the lower end to just under $264 million at the higher end.

Board member Reed Hastings has expressed interest in purchasing $300 million worth of shares, while Christopher Liddell has shown intent to buy $3 million worth of shares. Collectively, the seven founders will own around 3.2% of the company's outstanding Class A shares, totaling about 22% collectively. Though these shares represent their ownership in the company's equity, they should note that other entities, such as Amazon and Google, also hold non-voting Class N shares, reducing their overall equity control.

Despite this, the founders maintain control of the company, with a combined 51.1% of the votes. As siblings Dario and Daniela Amodei were part of OpenAI, along with five other OpenAI employees, Anthropic was created in 2021 as a response to disagreements over AI leadership. The founders have emphasized their focus on AI safety from the beginning of their venture.
