Kalshi prices the market at 95% confidence Anthropic announces before March 1, 2027, with nearly equal odds splitting the January and February deadlines, indicating strong conviction the IPO occurs in Q4 2026 or early 2027. However, recent reporting shows the IPO has slipped from early-September expectations; as of September 4-5, Anthropic now plans to file its prospectus in late September, begin marketing in mid-October, and list days before the November midterm elections. The market-implied timing remains tighter than the company's revised schedule suggests, pricing in moderate execution risk but betting the offering clears well before February 1.
As of September 9, 2026, the Kalshi odds for When will Anthropic officially announce an IPO? are: Before Apr 1, 2027: 97%, Before Jan 1, 2027: 96%, Before Mar 1, 2027: 94%, Before Feb 1, 2027: 93%, Before Dec 1, 2026: 90%.
