Anthropic Plans $1.5 Trillion IPO and May Let Shareholders Sell Shares

The AI developer intends to reveal its initial public offering prospectus after Labor Day, targeting a listing in late September or early October. Anthropic is leaning toward allowing existing shareholders to sell stock in the debut, a decision that departs from restrictions seen in other high valuation private companies.

Bankers have discussed a valuation around $1.5 trillion for the company. To limit volatility following the listing, the firm is considering longer than usual lockup periods and expects to host an investor day in mid-September.
