All 7 Anthropic co-founders are selling stock in the IPO, about $250M each.
The amended S-1 shows each founder selling 3,378,378 shares. At the $70–$78 range, that’s $236M–$264M apiece, about $1.75B together.
It’s expected to list on Nasdaq as ANT, pricing Nov 18 and trading Nov 19. At the top of the range it’s valued at up to ~$1.4T fully diluted.
Demand: $26B of private-placement orders at the IPO price (Nvidia, Google, Microsoft and more), and Reed Hastings’ fund wants $300M.
