Analysis generated Aug 31, 2026
Polymarket prices Anthropic's IPO closing market cap at 85% for 1.8T+, reflecting traders' confidence in a substantial post-debut pop from the $965B Series H valuation. Lead underwriters Goldman Sachs, JPMorgan, and Morgan Stanley are orchestrating what could become history's second-largest IPO, with expected close timing around October 2026 and revenue momentum—now at $65B annualized run-rate—outpacing near-term profitability risks. The 1.5–1.8T bracket at 11% represents the only material alternative, leaving less than 5% priced for outcomes below that range or a 2027 slip.
As of September 9, 2026, the Polymarket odds for Anthropic IPO Closing Market Cap (Middle Brackets) are: 1.8T+: 87%, 1.5–1.8T: 14%, No IPO by December 31, 2027: 2%, 1.2–1.5T: 2%, 0.9–1.2T: 1%. These probabilities are derived from real-money trading and update in real time.
