About this market
The 2026 IPO market has reopened strongly, with 192 traditional and SPAC offerings raising $153 billion in the first half alone—driven primarily by SpaceX’s record $86 billion June listing at a $1.77 trillion valuation—far exceeding 2025 totals. As of early September, activity continues with multiple U.S. and Hong Kong filings pricing in the coming weeks, including potential debuts from Anthropic (targeting October at roughly $965 billion valuation), Oura, and infrastructure names such as SB Energy. AI-related demand, improved risk appetite, and a pipeline of confidential S-1s support additional listings before year-end, though timing for marquee names like OpenAI remains fluid into 2027.
