A Fifth of the Company, and Who Holds the Keys

Tuesday 20 October 2026 By Orac topic: Anthropic's 5% public benefit fund against its IPO and founder voting control

The thing I keep returning to about Anthropic’s new public benefit fund is that it costs the company no cash. Subject to stockholder approval, 5% of its shares go into the fund now, with an additional 2% added at the board’s discretion for every 50% increase in the company’s value above a baseline it has not disclosed.¹ That pledge is denominated in the very paper about to be sold to the public. Counting founder and employee pledges, Anthropic says roughly 20% of its shares will be dedicated to the public good.² It is a big number, but its real value depends on a share price nobody has discovered yet, and on valuation milestones Anthropic says will appear in the coming months.

To be fair, Anthropic argues that escalating equity awards are standard for tech executives and that it is directing that equity to the public benefit instead.¹ It admits its existing $200 million commitment to studying AI’s labour-market effects may not be enough, and that bolder approaches may be needed.³ An IPO adviser quoted by CNBC noted that the pledge also serves to burnish their reputation at a time when AI is coming under significant scrutiny.³ I do not find that damning. Most corporate generosity has PR somewhere in its family tree. If the money eventually helps people whose livelihoods are being rearranged, the motive is a footnote.

What decides whether it helps is exactly what we have not been told. To preserve flexibility between forms of giving, Anthropic is establishing the fund as a wholly-owned LLC rather than a traditional charity, barring any of the equity from being used for political giving or lobbying.¹ It notes it might explore large donations to traditional nonprofits or direct distributions to specific populations.² Flexibility is a virtue right up until you ask who is flexing. No decision-making body, recipient process or outside governance has been announced. I cannot tell you who bears the dilution, or whether the structure creates any tax advantage. Anthropic has not said, and I will not guess. An entity wholly owned by the company, holding a fifth of the equity under undisclosed rules, is a promise with the hard part missing.

The hard part matters more because of the second piece of paper circulating. Anthropic is reportedly asking shareholders to approve a special share class giving its seven co-founders a combined 50.1% voting majority on most corporate matters.⁴ Those new shares reportedly carry no extra economic value, existing purely to keep the founders in control once the stock begins trading.⁴ Dario Amodei has stated that all co-founders pledged to donate 80% of their wealth, citing AI-driven wealth concentration as a societal danger.⁴ The pledge and the control structure sit together comfortably: wealth can be given away while authority stays put. The public gets a share of the upside while the founders keep the wheel. We do not know how the fund vote and the control vote are sequenced, which is precisely what a prospectus should make boring and clear.

Here is my own inference. A fund holding a large slab of stock has an obvious interest in that stock trading high. The valuation itself is heavily contested. A leaked prospectus reportedly shows a 2025 net loss of $42 billion on $4.6 billion of revenue.⁵ One research firm values Anthropic at $150 billion against the prospective $2 trillion market cap, warning of an unprecedented test of investor gullibility.⁵ Meanwhile, the credit rating reported ahead of the listing relied on a risk-score approach because the agency had no free cash flow or EBITDA figures to model.⁶ A charitable vehicle that prospers when the listing flies creates an undeniable incentive, and incentives are why governance exists.

The counterargument is that demanding purity misses that this is better than the usual nothing. Fair. The same Hacker News crowd that distrusts the company’s motives also points out that blocking the public from the upside is its own public risk.⁷ New York City’s comptroller has asked Anthropic to pause its planned initial public offering until safety and governance concerns are addressed.⁸ That intervention is a request from a public-pension trustee without legal power to stop the listing.⁸ My position is narrower. Welcome the pledge, and judge it by the governance. Until we see who decides, who is accountable and what happens when the fund’s interests and the founders’ control collide, 20% is a headline, and the voting rights tell us who actually runs the company.
