When you IPO, you’re getting wealthy off of Other People’s Money flowing in creating liquidity. When you have to buy out existing cap table folks (either through enterprise cashflow or financing), it becomes harder. An artifact of ZIRP evaporating after entire businesses were built on the VC IPO flip model (and profitability becoming king over growth at any cost).

It will take time for everyone’s expectations and actions to reach the new macro reality, with current participants attempting to "find a way out" that is most favorable for the circumstances.
