A stake that grows with the valuation
Anthropic announced the Anthropic Public Benefit Fund on its website on October 18. Subject to stockholder approval, 5% of the company's shares are committed now; after that, the board may add another 2% at its discretion for every 50% increase in the company's value above "a set baseline." In other words, the more the company is worth, the larger the fund's share can become. The announcement does not say what the baseline is or where the milestones sit.
Anthropic frames the equity against executive pay: tech companies commonly give executives escalating compensation awards, and it is directing that equity to the public benefit instead.
Why an LLC
The fund is a wholly owned limited liability company, not a 501(c)(3) nonprofit, the usual US vehicle. Anthropic says this allows adjustment between different forms of giving, such as large donations to traditional nonprofits or direct distributions to specific populations. Its example is AI's impact on the labor market: the company has already committed $200 million to studying the issue and says that, given the pace of AI progress, bolder approaches may be needed. The announcement also states that none of the Anthropic equity held by the fund will be used for lobbying or political giving, in the US or abroad.
Where "roughly 20%" comes from
The figure is not the new fund alone. When Anthropic was founded, its co-founders pledged to donate 80% of their equity, and the company runs an equity donation match program in which about half of employees participate. Anthropic says the three together come to roughly 20% of its shares, not counting any milestone-based additions. Reuters reports that Anthropic is preparing to go public as a public benefit corporation (PBC).
Anthropic says the fund's governance, the valuation milestones and its first public benefit report will come in the next few months. Until then, it is not possible to tell who decides how the money is spent or when the extra 2% would kick in.
