Recent equity market volatility, elevated Treasury yields near 5%, and selective investor appetite have tempered IPO timelines for major tech and AI firms, with several high-profile candidates like Anthropic and OpenAI signaling potential 2027 debuts amid valuation scrutiny and proof-of-revenue demands. Biotech and smaller deals continue to price successfully, reflecting sector-specific demand, while broader U.S. issuance has already surpassed prior-year records through Q3 2026. Goldman Sachs projects $175 billion in 2027 IPOs alone, underscoring a supportive pipeline if conditions stabilize. Key near-term catalysts include FOMC decisions, Q4 earnings, and any confidential filings or roadshows that could accelerate or further delay resolutions before year-end. Trader consensus on Polymarket reflects these uncertainties, with probabilities varying sharply by company readiness and macro backdrop.
