Anthropic Founder Commits 80% of Equity to Philanthropy Ahead of IPO

Anthropic’s chief executive, Dario Amodei, has pledged to allocate 80 % of his personal equity in the company to charitable causes. The pledge will be executed through two donor-advised funds—Daffy Charitable Fund and Dechomai Asset Trust—which allow donors to receive an immediate tax deduction while retaining control over the timing of grant distributions. The filing notes that Amodei retains voting rights over the shares placed in these funds, including any shares later acquired by them.

The SEC filing reveals that Amodei directly holds 240.6 million shares of Anthropic and an additional 4.6 million shares subject to voting proxies. Each of the seven co-founders owns over 200 million shares, a stake that could be worth billions if Anthropic achieves its projected valuation of more than $1 trillion. The company expects to go public in the month following the filing, meaning the pledged equity could translate into a substantial charitable endowment.

Amodei’s pledge follows an open letter he published in January, urging wealthy individuals—particularly in technology—to support workers and families displaced by artificial intelligence. The sentiment was reiterated during a meeting with French President Emmanuel Macron at the AI Impact Summit in New Delhi on February 19, 2026. The filing frames the pledge as a response to what Amodei described as a “cynical and nihilistic attitude” toward philanthropy among some tech elites.

Anthropic’s filing states that the company will match the founders’ share-based donations with additional contributions from staff equity, potentially adding billions of dollars to the charitable pool. The filing also clarifies that the donor-advised funds can receive highly appreciated private shares, allowing donors to avoid capital-gains tax on any future sale.

The move highlights a growing trend among newly wealthy tech founders to use donor-advised funds for large-scale giving, combining tax efficiency with flexible grantmaking. If the IPO proceeds as anticipated, the resulting charitable capital could set a precedent for future equity-based philanthropy in the technology sector.
