Anthropic’s seven co-founders will each sell 3,378,378 shares in the company’s upcoming IPO. That comes to roughly $250 million apiece at the midpoint of the proposed price range. TechCrunch AI reports that the detail appears in Anthropic’s newly filed S-1, the registration document a company must file before it lists on a U.S. exchange. The offering could value the Claude maker at as much as $1.4 trillion.
That would make it one of the largest IPOs on record. The filing also shows something less obvious than the payout: the founders are cashing out a little while keeping majority control.
The Quick Read
- Shares per founder: 3,378,378
- Price range: $70 to $78 per share, which TechCrunch AI calls “unusually broad”
- Payout per founder: about $236M at $70, just under $250M at $74, and just under $264M at $78
- Combined founder sale: about $1.75 billion at the midpoint
- Voting control after the IPO: 51.1% held by the founders as a group
- Early demand signal: board member Reed Hastings wants to buy $300M in shares through his donor-advised fund, and board member Christopher Liddell wants $3M
Who’s Selling
All seven founders are selling the same number of shares:
- Dario Amodei, CEO
- Daniela Amodei, president and board chair
- Tom Brown, chief compute officer
- Jack Clark, head of public benefit
- Jared Kaplan, chief science officer
- Sam McCandlish, chief architect
- Christopher Olah, interpretability research lead
The equal split stands out. You don’t usually see that in tech IPOs, where the CEO tends to hold a much bigger stake than everyone else. Here, according to the S-1, “no single founder will hold significantly more shares or votes than the others.”
How Control Works
After the sale, each founder will own about 3.2% of Anthropic’s outstanding Class A shares, or about 22% as a group. That figure overstates their economic stake, though. Class A is only one of Anthropic’s share classes. Big backers including Amazon and Google hold nonvoting Class N shares, so the founders own a considerably smaller slice of the company’s total equity.
Voting power is a different story. Each founder also gets one share of Class F stock, which carries supervoting rights. Together those shares give the seven founders 51.1% of the votes.
This matters because it means public shareholders can’t easily push Anthropic to change direction. The company has built its brand on putting safety ahead of speed. The founders left OpenAI in 2021 after disagreements with its leadership over how AI should be built. Dual-class structures like this one are common at founder-led tech companies, and here the setup works as a guardrail. The people who wrote the safety-first mission get to keep enforcing it after the company is public.
Why It Matters
For the AI industry: A $1.4 trillion valuation would put a frontier AI lab among the most valuable public companies in the world. It would also set a public-market benchmark for every other lab raising money. Private valuations have been climbing for years with no daily price to check them. Once Anthropic trades, investors get a live number.
For the founders: About $250 million each is a big payday, but it’s a small piece of what they own. Selling only a modest portion is a standard signal to new investors that insiders still believe in the company’s upside.
On demand: The board-level buy orders and the wide price range suggest Anthropic expects strong interest. As TechCrunch AI notes, hotly anticipated IPOs often price above their initial range. If that happens, every founder’s take goes up with it.
What to Watch
- Final pricing. A move above $78 would show investors are paying up for AI exposure even at these valuations.
- Governance scrutiny. Expect governance analysts and institutional investors to push back on the supervoting Class F shares, especially next to Anthropic’s public-benefit framing.
- Pressure on rivals. A successful listing raises the stakes for OpenAI and other labs weighing their own path to public markets.
Anthropic started as a breakaway group that thought the industry was moving too fast. Now it’s asking public investors to back that safety-first approach at a trillion-dollar scale, with the founders still holding the votes. TechCrunch AI has the full breakdown of the S-1 disclosures.
