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.
