Anthropic’s seven co-founders to sell $1.75B in stock in IPO

Founder liquidity of this scale at IPO is a structural signal about the offering's composition, not just a payday: it puts a large block of insider supply into the float from day one, which matters for how the stock absorbs demand after trading begins. The gap between the roughly $18 billion retained stakes and the $1.75 billion sold suggests founders are diversifying a modest slice rather than exiting, a distinction that shapes how the move reads. Whether the offering prices near the top of its range and how the shares trade once public will be the real test of whether that insider selling is digested quietly.
