According to TechCrunch, citing Anthropic's prospectus, the seven co-founders each plan to sell 3,378,378 shares. Based on the midpoint of the $74 per-share range cited in the report, this amounts to approximately $250 million per person. Following the sale, they intend to collectively hold about 22% of Class A shares and retain a 51.1% combined voting stake through Class F super-voting shares. The 22% figure refers exclusively to the Class A shareholding rather than total equity in the company, and the actual cash-out amount will depend on the final IPO pricing.
