Anthropic founders plan to sell shares worth nearly $250 million each during the company’s upcoming initial public offering. All seven co-founders intend to sell 3,378,378 shares, according to an updated regulatory filing released Nov. 10.
At the proposed IPO midpoint of $74 per share, each founder would receive approximately $250 million before taxes and expenses. The actual proceeds will depend on the final offering price.
Anthropic Founders Plan $250 Million Share Sales
The planned sales involve CEO Dario Amodei, President Daniela Amodei, Chief Compute Officer Tom Brown and Head of Public Benefit Jack Clark.
The remaining founders are Chief Science Officer Jared Kaplan, Chief Architect Sam McCandlish and Interpretability Research Lead Christopher Olah.
Anthropic’s updated SEC filing establishes an IPO price range of $70 to $78 per share.
At the lower end, each founder’s planned sale would generate approximately $236 million. At $78 per share, that figure would increase to nearly $264 million.
The seven founders would collectively sell approximately 23.65 million shares, potentially generating $1.75 billion at the midpoint.
Founders Retain Control After IPO
Despite their planned sales, the founders will retain substantial ownership in Anthropic. Each is expected to hold approximately 3.2% of outstanding Class A shares after the offering.
Collectively, they will own roughly 22% of that share class. However, their overall economic ownership will be smaller because Anthropic has multiple share classes.
The company also plans to preserve founder voting control through a special Class F share held by Founder LLC. This structure gives the founders collective control over 50.1% of votes on most shareholder matters.
TechAmerica previously examined Anthropic’s founder voting structure and its implications for shareholders.
Anthropic IPO Could Value Company at $1.4 Trillion
Anthropic plans to offer 825 million Class A shares, including newly issued stock and shares sold by existing shareholders.
The proposed offering could value the company at approximately $1.4 trillion on a fully diluted basis.
TechAmerica recently detailed Anthropic’s IPO pricing plans, including a separate $26 billion investment from major technology companies.
The filing also identifies potential purchases by existing board members. Reed Hastings has indicated interest in buying $300 million in shares through his donor-advised fund. Christopher Liddell has expressed interest in purchasing $3 million.
Those indications are not binding commitments, and the final allocations could change.
Anthropic expects to list on Nasdaq under the ticker ANT. The final IPO price will determine the founders’ actual proceeds and the company’s valuation at listing.
