Anthropic's seven founders each worth up to $14 billion in IPO filing
Each of Anthropic's seven co-founders holds a stake worth at least $13.7 billion, according to the company's own IPO paperwork.
Anthropic just showed, in writing, how much its seven founders are worth. This is real, filed data on how much wealth the AI boom is creating at the very top, and it shows how concentrated that wealth still is.
The seven people who quit OpenAI in January 2021 to start Anthropic still each hold almost exactly the same slice of the company, five and a half years later. On Monday, Anthropic filed its S-1 (the paperwork a company must file with regulators before it can sell shares to the public, the first formal step toward going public, called an IPO). That filing shows each of the seven founders owns about 240 million shares.
Anthropic's most recent private funding round, this spring, priced shares at $58.90 each, adjusted for a later stock split. At that price, 240 million shares works out to between $13.7 billion and $14.4 billion a person, the range the filing points to once small differences between each founder's exact share count are accounted for. Together, the seven hold about 1.69 billion shares, roughly 10 percent of the whole company. At $58.90 a share, that combined stake is worth close to $100 billion.
An IPO could push the number much higher. Wall Street estimates have pointed to Anthropic listing at a valuation near $2 trillion. If that holds, the founders' 10 percent would be worth roughly $200 billion between them, or between $27 billion and $29 billion each, close to double their paper wealth at the private price.
Two things stand out. The ownership split has barely moved since 2021: based on what the filing shows, no single founder has pulled meaningfully ahead of or fallen behind the other six. And the filing itself is what makes any of this knowable. A private company does not have to disclose who owns what; a company preparing to sell shares to the public does, because regulators require it before the public can buy in.
Each founder own about 240 million shares, according to the S-1 registration statement Anthropic filed with the Securities and Exchange Commission on Monday.via Fortune →
