Anthropic Co-Founders Hold $13 Billion Stakes, Pledge $79 Billion to Philanthropy
Anthropic's seven co-founders, who departed OpenAI in 2021 to establish a safer AI company, each own about 1.4% of the firm, translating to stakes exceeding $13 billion. According to Bloomberg, this valuation is based on Anthropic's latest private funding round, which raised $65 billion in May 2026, bringing the company's post-money valuation to $965 billion.
Philanthropic Commitment
The co-founders have committed to donating 80% of their personal stakes, amounting to an estimated $79.4 billion, to philanthropy. This pledge, while significant, is voluntary and non-binding, allowing the founders to maintain substantial voting power through a founder-controlled Class F share.
Company Growth and IPO Plans
Anthropic reported $16.8 billion in revenue for Q3 2026, marking a 46% increase year-over-year, despite facing substantial losses attributed to non-cash accounting items. The company is gearing up for an initial public offering (IPO) targeted for November 2026, with potential valuations ranging from $1.5 trillion to $2 trillion.
Governance Structure
As a public-benefit corporation, Anthropic's governance allows leadership to balance its mission of AI safety with shareholder returns. The co-founders, while owning a small fraction of the company's economics, collectively control 50.1% of the voting power through a newly formed Founder LLC.
