Anthropic’s Seven Co-Founders Near-Equal Stakes Could Be Worth $200B Post-IPO
TREE NEWS reports: Anthropic, the AI safety and research company, is preparing for an initial public offering that could value the company at $1.5 trillion to $2 trillion. A Fortune analysis of the company’s IPO filing reveals that its seven co-founders each hold nearly identical equity stakes, a structure that breaks sharply with Silicon Valley norms. Each founder’s stake could be worth $21 billion to $30 billion after the IPO, for a combined total of up to $200 billion.
The filing shows that each co-founder holds between 231 million and 244 million shares, along with identical grants of 2,185,400 immediately exercisable options and 639,500 restricted stock units (RSUs) that vest after the IPO. That gives each about 1.4% to 1.5% of the company. The seven founders—including CEO Dario Amodei and President and Board Chair Daniela Amodei—have committed to donating 80% of their shares to charity, a pledge that could total $80 billion to $165 billion, though it is not legally binding.
A Rare Egalitarian Structure
Compensation consultants say the equal split is highly unusual for a company of this size. “Giving all founders the same thing is itself unusual,” said Robin Ferracone, founder of Farient Advisors. “Typically, as vesting progresses, pay diverges based on role.” The Amodei siblings, the only named executive officers, each received a salary of $654,167 last year, plus stock and options valued at about $13 million at the time of the filing—or roughly $330 million at a $2 trillion valuation. In July, their salaries rose to $1.4 million. In February, each received about 1.4 million stock options and 2.4 million RSUs, followed by an additional 537,000 RSUs in July. At a $2 trillion valuation, those grants would be worth about $505 million each.
The company explained in its registration statement: “We consider internal pay equity in setting executive compensation. Each co-founder receives the same compensation.” The other five co-founders—Tom Brown, Jared Kaplan, Sam McCandlish, Jack Clark, and Chris Olah—hold C-level titles such as Chief Computing Officer and Chief Science Officer but do not appear in the compensation table. However, their identical option and RSU grants, vesting by late November, suggest they received equivalent awards.
Contrast with Musk’s SpaceX
The structure contrasts sharply with SpaceX, the last company to list at a similar scale. Before its IPO, Elon Musk received a total of 1.3 billion restricted shares in two tranches tied to market-cap milestones, including Mars colonization and space-based data centers. If all targets are met, those grants could be worth $650 billion to $700 billion—far beyond what anyone else at the company received. By contrast, Anthropic’s founders’ charitable pledge would still leave them with control of the company even after donating most of their wealth.
Notably, the two Amodeis already sold some shares in an April tender offer at $25.91 per share. Two board members who will oversee executive compensation after the IPO are also investors: Novartis CEO Vas Narasimhan, who chairs the compensation committee, bought about $10 million of Anthropic stock through a company he co-owns with his wife weeks after joining the board in May. The other committee member, Yasmin Razavi, is a general partner at Spark Capital, whose funds have invested $777 million in Anthropic since 2023.
Market Implications
For investors, the IPO could be a landmark event for the AI sector and the broader equity market. A $1.5 trillion to $2 trillion valuation would make Anthropic one of the most valuable companies in the world, rivaling the largest tech giants. The near-equal founder stakes and the charitable pledge may reduce concerns about insider selling and align incentives with long-term shareholders. However, the lack of legal enforceability on the charitable pledge and the potential for founder sales after lock-up periods could create overhang. The structure also raises questions about governance and control, as the founders would retain significant influence even after donating most of their shares.
The IPO could also impact the crypto market, as Anthropic is a major player in AI and blockchain intersection. However, the direct impact on crypto is likely limited unless the company announces blockchain-related initiatives. For now, the focus is on the equity market, where the IPO could set a new benchmark for tech valuations and founder compensation structures.
