Anthropic commits roughly 20% of its shares to the public good
The new Anthropic Public Benefit Fund starts with 5% of shares, adding 2% for every 50% increase in company value over a baseline, subject to the board — about 20% in total. Co-founders have pledged to donate 80% of their equity, and around half of employees are donating via a matching program. Notably it's a wholly owned LLC, not a 501(c)(3), for 'adjustability between different forms of giving' — with a pledge of no lobbying or political giving.
