Seven people left OpenAI to start Anthropic in January 2021. Five and a half years later, they’ve all ended up with almost the same slice of the company, according to the S-1 Anthropic filed with the SEC on Monday. Each founder owns roughly 240 million shares. At the $58.90 per-share price from Anthropic’s latest private round this spring, that works out to about $13.7 billion to $14.4 billion apiece.
The seven founders are Dario Amodei, Daniela Amodei, Tom Brown, Jared Kaplan, Sam McCandlish, Chris Olah and Jack Clark. Together, they hold about 1.69 billion shares, or roughly 10% of the company. Anthropic’s filing leaves the IPO price range and the number of shares being sold blank for now, but if the company lists at the roughly $2 trillion valuation Wall Street has been floating, each founder could land somewhere around $27 billion to $29 billion.
The ownership math gets a little messier once you look closer. The filing says those share counts include direct holdings, trusts, options and RSUs vesting within 60 days. Daniela Amodei’s total also includes roughly 264,500 options and RSUs held by her spouse. Dario Amodei is listed with 245 million shares overall, but 4.6 million of them sit in donor-advised funds that he votes under proxy agreements and no longer owns. If those are counted, his paper wealth moves up too.
The company’s public-benefit fund adds another huge number to the mix. Anthropic put 846.8 million shares into that vehicle, equal to 5% of its fully diluted shares as of June 30, assuming Amazon’s convertible notes fully convert. At the $58.90 price, that block is worth about $49.9 billion. And while each founder has pledged to give away 80% of their personal Anthropic equity, the filing is blunt that the pledge is voluntary and revocable, and that the founders can keep control even as they give stock away. The company’s own paperwork says that as donations rise, their economic interest falls while their voting control stays the same.
My take — AI-written commentary, not fact-checked reporting
This is the modern billionaire compromise in one neat package: keep the vote, donate the optics, and call it a mission. Anthropic’s founders get to look generous while staying firmly in charge, which is very on brand for Silicon Valley. The charity pledge sounds noble until the governance fine print shows who still holds the steering wheel.
