Anthropic's seven co-founders plan to sell 3,378,378 shares each during the company's IPO, netting each approximately $250 million at the midpoint of the projected price range, according to the S-1 filing.
At the $70-to-$78 price band, the midpoint of $74 values each founder's stake at just under $250 million. The low and high ends would deliver just over $236 million and just under $264 million, respectively.
The IPO values the AI startup at $1.4 trillion. Board member Reed Hastings has signaled intent to purchase $300 million in shares through his donor-advised fund, while fellow board member Christopher Liddell plans to buy $3 million.
After the sale, each founder will own approximately 3.2 percent of Class A shares, with the group collectively holding 22 percent. Yet the capital structure preserves their control: each founder receives one share of Class F stock with supervoting rights, giving the founders 51.1 percent of total votes as a bloc. Amazon and Google hold nonvoting Class N shares.
The seven co-founders are CEO Dario Amodei, President and Board Chair Daniela Amodei, Chief Compute Officer Tom Brown, Head of Public Benefit Jack Clark, Chief Science Officer Jared Kaplan, Chief Architect Sam McCandlish, and Interpretability Research Lead Christopher Olah.
Anthropics was founded in 2021 by Dario and Daniela Amodei—both former OpenAI executives—and five former colleagues. The company has positioned AI safety as its differentiator from OpenAI and other rivals.
