Anthropic Public Benefit Fund: what the 5% share pledge commits, what it could fund and what's still undecided

On Sunday, October 18, 2026, Anthropic announced the Anthropic Public Benefit Fund, a new company-owned entity that will receive 5% of its shares if stockholders approve. The board may add 2% more for every 50% increase in Anthropic's value above "a set baseline," which the company hasn't published. Anthropic says the fund could make large donations to nonprofits or pay money directly to specific groups of people, and it names AI's effect on workers as one example. It hasn't said who will run the fund.

This story is based on Anthropic's October 18 post, OpenAI's structure pages, and reporting by Forbes, The National, MIXED and Bloomberg (read through Business Standard's syndicated copy), checked October 20, 2026. It isn't investment advice. The fund is separate from the board-electing trust covered in our explainer on Anthropic's Long-Term Benefit Trust.

The short version

• What: 5% of Anthropic's shares committed to a new fund, "subject to stockholder approval." Anthropic's post doesn't name a share class or a share count.
• Uses: large donations to nonprofits or "direct distributions to specific populations." AI's impact on the labor market is the example given.
• Limit: none of the fund's Anthropic equity will be used "for lobbying or political giving, in the US or abroad."
• Open: governance, the baseline and named recipients. Anthropic says it will share the structure and governance "in the coming months."

What exactly did Anthropic commit?

The post, titled "Investing in the public benefit," says: "Subject to stockholder approval, 5% of Anthropic's shares will be committed today." Until stockholders vote, on a date Anthropic hasn't given, the 5% is a commitment, not a completed transfer.

The growth mechanism is optional. Additional grants of 2% come "at the board's discretion" for each 50% rise "above a set baseline." Anthropic says it is redirecting equity that tech companies often give executives as escalating awards.

Anthropic also gave a total. It says the co-founders pledged at founding to donate 80% of their equity, and that roughly half of employees take part in an equity donation match. With the new fund, it says, "roughly 20% of Anthropic shares will be dedicated to the public good," before any milestone additions. That 20% mixes two different things: personal pledges by founders and employees, and a fund the company itself owns.

What will the fund pay for?

Anthropic says the LLC form gives "adjustability between different forms of giving," such as large donations to traditional nonprofits or direct distributions to specific groups. Its example is the labor market. Anthropic says AI "could also cause instability for many workers," and points to the $200 million it has already committed to studying and addressing that issue, a pledge AP reported on June 10, 2026. The fund, it says, could support "bolder approaches." No recipients, programs or amounts have been named.

Safety and interpretability research, applied biomedical work and Claude discounts for nonprofits and scientific institutions stay inside the company, the post says.

How big could it be?

Anthropic gave no dollar value. Using reported valuations:

• Forbes estimated on October 19 that 5% could be worth about $100 billion at a $2 trillion IPO valuation. Reuters has reported both "more than" and "up to" $2 trillion (our IPO explainer shows the difference). Forbes noted that's share value, not cash, assuming no dilution.
• At the $965 billion valuation from Anthropic's most recent round, cited by Bloomberg, 5% would be about $48 billion. That's 9to5AI's arithmetic, not a figure from Anthropic.

The same week, Bloomberg reported on October 19 that former Google CEO Eric Schmidt owns "around 1%" of Anthropic, citing people familiar with the matter. According to Bloomberg's story as syndicated by Business Standard, Schmidt invested tens of millions of dollars in the 2021 Series A, when Anthropic was valued at $461 million. Bloomberg said a $2 trillion debut would raise his net worth by about a third, to nearly $80 billion. Schmidt and Anthropic declined to comment. On those figures, the fund's starting stake would be about five times Schmidt's.

How does it relate to the trust and the IPO?

Anthropic's post doesn't mention the Long-Term Benefit Trust or the IPO. They are different things. The trust holds Class T stock that elects directors, and its trustees have no economic stake. The fund, as described, holds an economic stake but has no announced governance role. Whether its shares would carry votes isn't stated.

Anthropic confidentially submitted a draft S-1 on June 1, 2026, and Bloomberg has reported that IPO marketing could start as soon as the week of November 9 (our IPO explainer). Forbes noted that it's unclear how the IPO would affect the fund's setup or its ability to turn shares into cash. For the revenue behind the valuation, see our story on the $16.8 billion quarter.

How does it compare with the OpenAI Foundation?

Last verified: October 20, 2026

OpenAI's 26% predates its 2026 fundraising and may since have been diluted. OpenAI hasn't published an updated figure (OpenAI explained). The main difference is control: OpenAI's foundation picks the board, while Anthropic's fund, so far, is a holder of equity and a giving vehicle.

Reaction

Critics responded on X, Forbes reported. Elon Musk wrote, "I recommend giving the shares directly to the public." David Sacks wrote that "whether it serves the public good remains to be seen." Anduril co-founder Palmer Luckey called it "USAID 2.0."

What's confirmed, reported and uncertain

• Confirmed (Anthropic, October 18): 5% subject to stockholder approval; the 2% per 50% mechanism at the board's discretion; the LLC form; the ban on lobbying and political giving; example uses; the "roughly 20%" total; governance details to come.
• Confirmed (OpenAI): the Foundation's 26% stake, its warrant and its board appointment rights; the $25 billion commitment.
• Reported: Schmidt's roughly 1% stake (Bloomberg, people familiar); value estimates (Forbes; Bloomberg); IPO timing (Bloomberg).
• Uncertain: the vote date, the baseline, the share class, who governs the fund, whether its shares vote, and when it would make its first grants.
