**Market volatility and valuation skepticism have prompted several high-profile IPO postponements in recent weeks, tempering expectations for major listings before year-end.** Oura delayed its roughly $2.2 billion offering in late September citing market uncertainty, while Anthropic shifted from an earlier fall target toward November or later and OpenAI moved plans into 2027. Bond yields near 19-year highs, AI spending concerns, and selective investor demand have reduced risk appetite, with the fourth-quarter calendar starting quiet and few sizable deals priced for early October. Seasonal slowdowns ahead of holidays and potential election effects further compress the window. Smaller or SPAC-related activity continues, but trader consensus on big-ticket IPOs by December 31, 2026, reflects these near-term hurdles and the limited runway remaining.
