Anthropic said on October 18 (early October 19, Beijing time) that it is committing part of its shares to a new entity called the Anthropic Public Benefit Fund. Subject to stockholder approval, 5% of the company's shares will go in now, and the board can add another 2% for every 50% rise in Anthropic's value above a set baseline. Counting pledges its co-founders and employees have already made, Anthropic says roughly 20% of its shares will be dedicated to the public good.

What's going in

The 5% is the part tied to this announcement, and it still needs stockholder approval. The later 2% additions are up to the board, and Anthropic hasn't said what the baseline valuation is. It says it will share the valuation milestones, along with the fund's structure and governance, in the coming months.

The roughly 20% figure adds two earlier commitments to today's 5%. When Anthropic was founded, its co-founders pledged to donate 80% of their equity. The company also runs a donation match program in which employees pledge equity and Anthropic matches it, and it says about half of its employees take part. Anything the fund gains from future valuation milestones would come on top of that.

Anthropic compares the growing stake to the escalating pay awards tech companies often give their executives. It says it is directing that equity to the public benefit instead.

What the money might go toward

Anthropic is a public benefit corporation, and it says most of its mission work happens inside the company, such as safety and interpretability research, applied biomedical research, and discounts on Claude for nonprofits and scientific institutions. The new fund is meant to give it more flexibility and scale. As examples, Anthropic says it "might explore large donations to traditional nonprofits or direct distributions to specific populations."

It names one area as an example: the labor market. Anthropic writes that AI could create enormous economic value but could also cause instability for many workers. It says it has already committed $200 million to studying and addressing this, and that bolder approaches may be needed given how fast AI is moving. It hasn't said who would receive money from the fund, how much, or when.

How the fund is set up

The fund is a wholly owned LLC rather than a 501(c)(3) charity. Anthropic says it picked that format so it can adjust between different kinds of giving. It also says none of the Anthropic equity held by the LLC will be used for lobbying or political giving, in the US or abroad. Separately, the company says it will report on its progress toward its mission in an upcoming public benefit report.
