The fall 2026 IPO window remains open but selective, with 109 U.S. deals priced for $146.5 billion through mid-September amid strong equity markets and AI-driven demand. Valuation mismatches between issuers and investors have triggered recent postponements, while mega-cap candidates such as OpenAI lean toward 2027 targets near $1 trillion to meet internal hurdles. Anthropic’s confidential filing positions it for a potential October listing around $965 billion, and names like Oura and Accelevation are slated for near-term pricing. Broader pipeline visibility supports 40–70 additional sizable offerings by year-end, though macroeconomic stability, Fed policy signals, and aftermarket performance will determine whether the rebound sustains into Q4 or shifts activity to 2027. Trader sentiment reflects this balance of momentum versus execution risk.
