Anthropic Plans to Commit 5% of Its Shares to a Public Benefit Fund Ahead of IPO

Anthropic said on Sunday, October 18, that it plans to commit 5% of its shares to a newly created Anthropic Public Benefit Fund, subject to stockholder approval. The board will also have the discretion to add another 2% each time the company's value rises 50% above a set baseline, which Anthropic has not disclosed. The fund is structured as a wholly owned LLC rather than a nonprofit, is barred from lobbying and political donations, and could make large donations to nonprofits or direct distributions to specific groups, with people whose jobs are affected by AI cited as one example.

The dollar value depends on which valuation you use. Yahoo Finance put the stake at about $48 billion, based on the roughly $965 billion valuation from Anthropic's May funding round, and about $75 billion at the $1.5 trillion IPO valuation some investors have discussed. Forbes estimated about $100 billion if the IPO reaches a valuation above $2 trillion, while noting that figure is share value rather than cash. Anthropic frames the commitment as bringing roughly 20% of its shares dedicated to the public good, counting its cofounders' earlier pledges and an employee donation-match program, though it has not shown how those pieces add up.

The timing puts the fund squarely in the IPO conversation. Anthropic could list as soon as November, and commentary this week has ranged from a Bloomberg Opinion argument that its IPO hopes may be eclipsed by cloud companies to what a weak debut for Anthropic or OpenAI would mean for AI stocks. Open questions for prospective buyers include whether the fund's shares will be newly issued, which would dilute other holders, and how the fund will turn stock into cash. Elon Musk criticized the structure, writing "I recommend giving the shares directly to the public", and has since pledged a SpaceX share to every U.S. child.

What to watch: the stockholder vote, the valuation milestones and governance details Anthropic says it will publish in the coming months, and how the fund is described in the IPO prospectus. For listed AI names such as MSFT and SPCX, the Anthropic offering is shaping up as the next big test of how much public investors will pay for AI growth.
