Anthropic Plans Initial Public Offering With A $2 Trillion Valuation And Potential Employee Stock Sale Restrictions

Anthropic is preparing to launch its initial public offering (IPO) in the coming weeks, with a projected valuation of $2 trillion. The company plans to release its prospectus after Labor Day, with a potential listing in late September or early October 2026. Morgan Stanley and Goldman Sachs are expected to lead the IPO, with Goldman Sachs serving as the stabilization agent. Other banks, including JPMorgan, Citigroup, and Barclays, are also expected to benefit from the offering. Amazon and Alphabet are major investors in Anthropic, holding stakes that would be worth over $420 billion and $280 billion respectively if the company hits its $2 trillion valuation. Anthropic is also considering a unique restriction where all employees, including rank-and-file staff, would be required to use preset Rule 10b5-1 trading plans to sell shares. These plans allow employees to set stock-sale instructions in advance to avoid timing sales based on insider information. The company is also weighing longer lockup periods than the customary 180 days to manage share supply.
