anthropic is setting aside 5% of its shares for a new public benefit fund, the company announced on oct 18. the stake can grow by another 2% for every 50% rise in anthropic's value above a set baseline. the commitment still needs stockholder approval.

the fund's rules

the fund is a wholly owned llc, not a charitable foundation. anthropic says the structure gives it more ways to give:

large donations to traditional nonprofits
direct payments to specific groups of people
support for workers if ai makes their jobs less stable

none of the fund's equity can go to lobbying or political giving, in the us or abroad. the extra 2% steps are added at the board's discretion.

together with earlier pledges, about 20% of anthropic's shares are now set aside for public benefit. the co-founders pledged 80% of their own equity when they started the company. about half of employees donate equity through a company matching program.

open questions

anthropic has not said who will run the fund or how it will be governed. it has not named the baseline valuation behind the extra 2% steps. it has not given a dollar figure either. the company says it will share these details in the coming months.

earlier pledges and the ipo

the fund adds to earlier programs. anthropic has already committed $200m to research on how ai affects the labor market. it and opeanai joined a $15m simons foundation initiative that helps mathematicians check and build on ai-generated proofs. anthropic also gives the researchers access to its models and compute.

the fund arrives about a month before anthropic's ipo. reuters reports the listing is expected in november at a valuation of up to $2t. at that price, 5% of the shares would be worth about $100b, our estimate. reuters also reports that some investors are weighing a lower valuation, so the final figure could be smaller.
