Anthropic's IPO paperwork has put numbers on how its seven co-founders will take part in the offering. According to TechCrunch's report on the S-1 filing, each founder plans to sell exactly 3,378,378 shares.
The numbers
Anthropic has floated an unusually wide initial price range of $70 to $78 a share. The proceeds per founder depend on where the offering prices:
- At $70: just over $236 million each.
- At the $74 midpoint: just under $250 million each.
- At $78: just under $264 million each.
The report notes that heavily anticipated offerings often price above the initial range, so these figures are a floor for that scenario rather than a ceiling. The filing also shows early demand: board member Reed Hastings has said he wants to buy $300 million of shares through his donor-advised fund, and board member Christopher Liddell wants to buy $3 million. The source says the IPO could value the company at $1.4 trillion; that is a possibility, not a confirmed valuation.
Who keeps control
After the sale, each founder will own about 3.2% of the outstanding Class A shares, roughly 22% together. The report emphasizes that this does not reflect their portion of the entire company. Because Amazon and Google own Class N shares, which carry no voting rights, the founders' share of overall equity is considerably smaller.
Control comes from a different instrument. Each founder also receives one share of Class F stock with supervoting rights. Together the seven will control 51.1% of the votes, and no single founder holds significantly more shares or votes than the others.
The seven are Dario Amodei (CEO), Daniela Amodei (president and board chair), Tom Brown, Jack Clark, Jared Kaplan, Sam McCandlish and Christopher Olah. They left OpenAI in 2021 to found the company.
What is not in the source
The filing as reported says nothing about product plans, pricing or customer terms. The final price and the date of the offering are not stated in the source text.
