**Strong 2026 IPO momentum, anchored by SpaceX’s record ~$75–86 billion June debut and over 100 deals raising roughly $146.5 billion through mid-September, underpins trader pricing for several high-profile listings by December 31, 2026.** AI infrastructure and tech names continue to dominate pipelines, with Anthropic targeting an October Nasdaq debut while OpenAI’s confidential filing leaves timing fluid between late 2026 and 2027. Recent selective appetite—evident in mixed first-day pops and pullbacks—reflects caution over AI spending sustainability, 19-year highs in Treasury yields, and potential Fed policy shifts, which can compress valuation multiples and delay roadshows. Upcoming catalysts include Oura and Accelevation pricings plus any additional S-1 filings, which could shift market-implied odds as equity-market volatility and institutional demand evolve through year-end.
