The US IPO market has sustained strong momentum into September 2026, with multiple offerings scheduled in the coming weeks—including Holtec Nuclear targeting an $825 million raise—and the fall calendar building on H1 proceeds exceeding $114 billion, the strongest first-half total since 2021. Supportive equity valuations, robust corporate earnings growth, and sustained demand for AI-related and growth names have encouraged issuers to proceed, while low withdrawal rates signal favorable window conditions. Key near-term catalysts include potential October listings such as Anthropic and additional filings expected before year-end, with resolution of the market hinging on equity market stability and execution of the remaining 2026 pipeline.
