Anthropic’s seven co-founders are each preparing to sell more than 3.3 million shares in the artificial intelligence company’s planned initial public offering, potentially generating nearly $250 million apiece as the Claude developer moves toward a listing that could value it at $1.4 trillion.
Details contained in Anthropic’s newly filed registration statement, known as an S-1, show that each founder plans to sell exactly 3,378,378 shares. The company has proposed an initial price range of $70 to $78 per share, putting the value of each founder’s planned sale at approximately $236 million to $264 million.
At the midpoint of $74, each would receive about $250 million before applicable taxes and transaction costs.

The proposed price range is unusually broad, and the final offering price could exceed it if demand proves sufficiently strong. The scale of the potential listing and early indications of investor interest suggest that the offering could attract substantial attention from institutional investors seeking exposure to one of the leading companies in the AI industry.
The S-1 also identifies significant potential purchases by two members of Anthropic’s board. Reed Hastings, the Netflix co-founder, has indicated an intention to buy $300 million worth of shares through his donor-advised fund. Christopher Liddell, another board member, plans to purchase $3 million worth.
Those proposed purchases would provide additional demand for the offering, although the filing’s disclosures do not establish that the indicated orders will necessarily be completed at the final IPO price.
Founders Retain Majority Voting Control
The seven founders are chief executive Dario Amodei; Daniela Amodei, the company’s president and board chair; Tom Brown, chief compute officer; Jack Clark, head of public benefit; Jared Kaplan, chief science officer; Sam McCandlish, chief architect; and Christopher Olah, interpretability research lead.
Following the planned share sales, each founder is expected to own approximately 3.2% of Anthropic’s outstanding Class A shares. Together, they would hold roughly 22% of that share class.
That figure does not represent their combined ownership of the entire company. Anthropic has multiple classes of shares, including Class N stock held by investors such as Amazon and Google. The founders’ combined stake in the company’s total equity is therefore considerably smaller than their share of Class A.
Their influence over the company, however, will remain substantially greater than their economic ownership alone might suggest.
Each founder will also receive one share of Class F stock, a special class carrying supervoting rights. Collectively, the seven founders will control 51.1% of Anthropic’s voting power, allowing them to retain majority control over corporate decisions even after selling millions of shares through the IPO.
The structure separates the founders’ ability to realize part of their financial stakes from their control over the company’s direction. No single founder will hold significantly more shares or voting power than the others, according to the filing.
For public-market investors, that arrangement is important because purchasing shares in Anthropic will not necessarily translate into proportional influence over its governance. The founders will retain decisive voting authority, while outside shareholders will have a more limited role in determining major corporate decisions.
The planned sales also offer an indication of how the founders are approaching the transition from a privately held AI company to a publicly traded business. They will be able to convert a portion of their holdings into cash while maintaining substantial exposure to Anthropic’s future valuation and growth.
From OpenAI Departures To A Major Public Offering
Anthropic was founded in 2021 after a group of senior OpenAI employees left the company following disagreements over its leadership and approach to developing artificial intelligence.
Dario and Daniela Amodei, who had held senior research and policy positions at OpenAI, joined five former colleagues to establish the new company. Their stated objective was to build advanced AI systems with a stronger emphasis on safety and responsible development.
The founders positioned Anthropic as an alternative to OpenAI, arguing that the development of increasingly capable AI systems required greater attention to potential risks and safeguards.
That emphasis became a central part of the company’s identity as it expanded its research operations and developed Claude, its family of AI models and chatbot services.
The proposed IPO represents a major financial milestone for a company that began as a breakaway group of researchers and executives. A potential $1.4 trillion valuation would place Anthropic among the world’s most valuable technology companies and give public-market investors a direct opportunity to invest in its AI business.
However, the founders’ planned share sales and the company’s dual-class ownership structure also raise questions about the balance between investor participation, founder control, and long-term corporate governance.
The immediate attraction is the scale of the offering and the opportunity to gain exposure to a leading AI developer. The longer-term consideration is how public shareholders will assess a company in which the founders retain majority voting power while holding a much smaller proportion of total equity.
The S-1 provides the first detailed picture of how the founders intend to participate financially in the listing. Their planned sales could deliver hundreds of millions of dollars to each, while the supervoting structure ensures they remain firmly in control of Anthropic after it enters the public market.
