- The Fund starts with 5% of Anthropic's shares, and the board can add 2% for each 50% rise in value above an undisclosed baseline.
- At the valuation of more than $2 trillion that Anthropic's draft prospectus targets, the initial 5% alone would be worth about $100 billion on paper.
- Anthropic built the Fund as a wholly owned LLC, so its board keeps control of the equity until it publishes the Fund's governance rules.
Anthropic will place 5% of its shares in a new Anthropic Public Benefit Fund, subject to stockholder approval, and has written an escalator into the structure that lets its board add a further 2% for every 50% increase in the company's value above a set baseline. The announcement, published on October 18, lands ahead of an expected listing, which means public investors will buy into a company that has already promised a growing slice of itself to purposes outside the shareholder return.
Anthropic's Public Benefit Fund grows as the company's valuation grows
Anthropic describes the Fund as a vehicle for work that sits awkwardly inside a company: large donations to traditional nonprofits, or direct distributions to specific groups of people. The one area it names is labor market disruption, where it has already committed $200 million to research and says “bolder approaches may be needed.” The timing fits that concern. Anthropic's own workforce data, published days earlier, showed junior technical hiring falling from 27% to 9% of its intake.
The Fund adds to pledges made at founding. Anthropic says its co-founders promised to donate 80% of their equity and that about half of employees take part in an equity donation match. Combined with the new Fund, the company puts the share of Anthropic “dedicated to the public good” at roughly 20%.
“It is common practice for tech companies to offer escalating compensation awards to their executives. We are instead directing that equity to the public benefit.”

The escalator copies the design of an executive mega-grant
The comparison Anthropic chose is precise. Performance-linked stock awards hand an executive more equity as the share price clears set milestones, and the Fund works on the same trigger, with the public interest in the executive's seat. If every step were added, the stake would reach 7% at 1.5 times the baseline value, 9% at 2.25 times and 13% at roughly five times.
Two caveats limit how far the chart can be read. Each extra 2% requires a board decision, and Anthropic has yet to disclose the baseline valuation or the milestones, which it says will come “in the coming months.” The chart therefore shows the ceiling of the design, and the real stake depends on decisions the board has yet to make.
Ownership and control of the stake stay inside Anthropic
Choosing a wholly owned LLC over a 501(c)(3) charity is the structural detail with the most consequence. Anthropic says the format gives “adjustability between different forms of giving,” and it bars the equity from use in lobbying or political giving in any country. A wholly owned subsidiary also means the shares remain inside Anthropic's corporate tree, directed by the same board that runs the company, at least until the promised governance rules say otherwise.
OpenAI took the opposite route. Its 2025 recapitalization left the nonprofit OpenAI Foundation holding 26% of OpenAI Group PBC, worth about $130 billion at the time, along with special voting rights to appoint the company's entire board and a warrant for more equity if the share price rises more than tenfold after 15 years.
| Anthropic Public Benefit Fund | OpenAI Foundation | |
|---|---|---|
| Starting stake | 5% (subject to stockholder approval) | 26% |
| Growth mechanism | +2% per 50% value rise, board discretion | Warrant if share price rises 10x+ after 15 years |
| Legal form | Wholly owned LLC of Anthropic | Nonprofit parent |
| Control over company | None stated | Appoints all OpenAI Group directors |
| Political use | Barred from lobbying and political giving | Not addressed on structure page |

OpenAI's nonprofit holds a larger stake and controls the company, while Anthropic's Fund holds a smaller, growing stake that the company controls, so the two labs have arrived at mirror-image answers to the same question about who owns the upside of AI.
Public investors will price the escalator into Anthropic's IPO
For anyone weighing the coming listing, the Fund is a dilution schedule tied to success. Each 2% step the board approves transfers value from ordinary holders exactly when the stock is performing best, and existing holders, including Anthropic's large strategic backers, must approve the initial 5% before it takes effect. Disclosure before listing lets the market price that cost from the first trade, which is easier to defend than a commitment added after investors have bought in.
The Fund also gives Anthropic a ready answer to a political and economic question that will sharpen as its models reach more jobs. A company reporting $16.8 billion in quarterly revenue can now point to a mechanism that grows its giving in proportion to its own value, with labor displacement named as a first target and the AI safety research it funds remaining inside the company.
Anthropic has tied a share of its future wealth to the disruption its products may cause, and the open question is governance. Until the baseline, the milestones and the Fund's decision rules are published, the 5% stands as a credible pledge whose final size and direction remain in the hands of the board that controls it.
