Anthropic announced on October 18 that it plans to put 5% of the company's equity into a newly created Anthropic Public Benefit Fund. The commitment still needs shareholder approval.
The announcement also builds in a top-up mechanism: each time the company's valuation climbs 50% above a set baseline, the board may, at its own discretion, add a further 2% of shares to the fund. The announcement does not say what the baseline is. In Anthropic's own words:
"the more Anthropic grows, the larger the share of the company that can be dedicated expressly to the public good"
How the fund is structured, and what limits it
The fund is a limited liability company (LLC) wholly owned by Anthropic. It is not registered as a 501(c)(3) charity under US tax law. The company explains that this keeps room to adjust between different ways of giving.
The announcement sets one hard limit: Anthropic equity held by the fund may not be used for lobbying or political contributions, whether inside or outside the United States.
As for where the money goes, the announcement only points to directions. The fund could make large donations to traditional nonprofits, or send money directly to specific groups of people. The example given is the impact of AI on the labor market. In June this year, Anthropic separately set aside $200 million to study and respond to that issue, and the new fund "may take bolder approaches."
The fund's structure, how it will be governed, and which valuation milestones trigger a top-up are all things the company says it will publish in the coming months. For now they remain blank.
Adding up to roughly 20%
Before this 5%, Anthropic already had several equity arrangements for the public good. According to the announcement, the co-founders pledged at the company's founding to give away 80% of their respective holdings. Employee share donations are matched by the company, and about half of employees take part. Add these to the new fund and about 20% of the company's shares will be devoted to the public good, not counting any top-ups triggered by valuation milestones.
A rough calculation of that 5%
Anthropic's funding round in May this year closed at a post-money valuation of $965 billion. On that figure, 5% works out to roughly $48 billion. That is paper value: the shares are not publicly traded and cannot be turned into cash for now.
OpenAI offers a useful comparison. In July it was reported that OpenAI intended to hand 5% of its equity to a US sovereign wealth fund. At its March valuation of $852 billion, that is about $42.6 billion, with returns designed to be paid directly to American citizens. The two companies are setting aside the same percentage but sending it to different places: OpenAI's stake would go to a government-led fund, while Anthropic's stays in its own wholly owned company, with its own board deciding on top-ups.
Paper value and spendable money are two separate ledgers. Equity in a private company can only be converted to cash through an IPO, a buyback or a secondary share transfer. Until then, the fund would have to rely either on extra cash from Anthropic or on borrowing against the shares, and the announcement explains neither route.
Our judgment is that in the first year after the governance details are published, the fund's actual spending will stay in the range of hundreds of millions of dollars, directed mainly at labor-market projects, with no single grant in the tens of billions. Once Anthropic completes an IPO and lets the fund sell shares, that assessment will need to be revisited.
