The December rush isn’t random. Companies that spent 2023-2024 waiting for better conditions are racing to market before potential volatility returns. The window opened—and everyone rushed through simultaneously.

What the Surge Signals

IPO volume is a leading indicator of market confidence. Twenty-five December debuts represent collective conviction that conditions are right. The surge also reflects pent-up supply—unicorns that delayed IPOs need liquidity for employees, investors, and growth capital.

Quality vs. Quantity

Not all IPO windows are equal. Are these quality companies achieving fair valuations, or marginal companies exploiting temporary enthusiasm? History suggests late-cycle windows often favor issuers over investors. The asymmetric information problem intensifies when companies rush to market.

2026 Outlook

December’s surge sets the stage for 2026. If these IPOs perform well, expect continued robust issuance. If they struggle, the window may close as quickly as it opened. For private companies still waiting: windows don’t stay open forever.
