Citing Anthropic's S-1, investor Michael Mott details the IPO lock-up structure: 825M shares offered, but 316M shares held by non-founder directors, officers, employees and consultants unlock on day one — nearly 40% of the deal. Further unlocks follow on days 27, 48 and 76, totaling 1.6B tradable shares within 76 days (about 2x the offering), with another 1.7B unlocking after annual results, likely in January. He notes this implies ongoing dilution pressure. Gary Marcus shared it with a pointed take: "Anthropic is here to fleece humanity, not save it," reading the lock-up design as a cash-out signal.
