Two AI powerhouses, OpenAI and Anthropic, are lining up IPOs that could unlock roughly $430 billion in pledged philanthropic commitments, a scale that would echo the monumental philanthropy of the Gilded Age giants.

Anthropic alone is projected to donate about $110 billion from its seven co-founders, who vow to give 80% of their wealth to charity, complemented by an estimated $60 billion from employee donor-advised funds and company matching.

The timing of these donations hinges on IPO schedules and ongoing commitments from founders, executives, and staff, with no fixed dates and the possibility that pledges could change.

Observers say the real social impact depends on whether pledges translate into actual giving, including collaborative efforts like a $500 million vaccine donation involving OpenAI, Anthropic, and Stripe.

OpenAI’s philanthropic apparatus, notably the OpenAI Foundation, could hold as much as 26% of OpenAI’s stock and channel roughly $260 billion into charitable funding through grants and partnerships.

If both firms meet their pledges, combined giving could reach about 1.3% of US GDP and would exceed the Internet-era philanthropic total, which hovered around $230 billion from 1990 to 2018.
