What Is the Backstage Bubble?
The backstage bubble refers to the rapid expansion of private market valuations, especially in venture capital and growth equity, where companies raise large rounds at steep premiums before reaching public markets. Fueled by abundant capital, low interest rates in recent years, and strong investor demand for exposure to high-growth startups, private valuations have climbed well above historical averages, raising concerns about mispricing and liquidity risk Forbes.
