All 7 Anthropic founders will each cash out about $250M in IPO

As Anthropic barrels toward an enormous IPO that could value it at $1.4 trillion, the company has disclosed a tidbit in its new S-1 filing about how many shares each of its seven co-founders plan to sell.

Each will sell 3,378,378 shares. Anthropic has floated an unusually broad initial price range of $70 to $78 a share. At the midrange of $74, each founder would take in just shy of $250 million.

The seven co-founders are Dario Amodei, CEO; Daniela Amodei, president and chair of the board; Tom Brown, chief compute officer; Jack Clark, head of public benefit; Jared Kaplan, chief science officer (pictured above); Sam McCandlish, chief architect; and Christopher Olah, interpretability research lead.
