Plan to sell $1.75 billion in stock… 7 Anthropic founders

Seven Anthropic co-founders plan to sell a combined $1.75 billion of stock in the company's upcoming IPO next week, with each founder offloading roughly $250 million at the midpoint of the offering range, or about 1.5% of their holdings. The sale marks the first insider liquidity event tied to the listing, following earlier tender offers in June 2025 and April 2026 in which co-founders Dario and Daniela Amodei participated; the remaining five co-founders are included in this plan. The move matters because it tests investor appetite for shares in the AI developer at its public-market debut while giving early leadership a partial exit. What to watch next is whether the offering prices within the stated range and how the stock trades once insiders begin converting paper wealth into cash.
