First-order effects

• Late-stage tech companies lose their exit route: with no $1B+ debut all year, founders and their backers who priced off the 2021 window are stuck holding private valuations they cannot monetize.
• Underwriters and exchanges lose the fee pool almost entirely — $8.6B in proceeds versus $155.8B a year earlier removes the deal flow that banks' equity capital markets desks were staffed around.

Second-order effects

• Capital and listing activity migrate to markets that stayed open — the related coverage shows Chinese tech IPOs still raised roughly $14B in 2021 while India's grew 550%, so issuers weigh alternative venues when the US window shuts.
• Private markets absorb the deferred supply: companies that would have listed instead raise privately or cut costs, shifting bargaining power toward late-stage investors who can wait out the window.

Third-order effects

• If the pattern holds, the IPO market reopens narrowly rather than broadly — the 2025 recovery ran on AI and crypto themes at less than half of 2021's deal count, suggesting listings become concentrated in whatever narrative investors will fund rather than distributed across the pipeline.
• A multi-year gap between vintage classes of public tech companies thins the bench of newly listed names, which structurally concentrates index and fund exposure in incumbents that listed before the freeze.
