I am old enough to have had multiple career changes since starting on a major firm’s rates floor in 2008. These IPOs are tiny compared to the overall stock market and the stock market is absolutely tiny compared to debt markets. People consistently underestimate the size of the world economy or even their local economy. The world may look small from an orion capsule near the moon but almost every aspect of human society is bigger than most people can reason about. It is possible these IPOs have an outsized impact on sentiment for weird reasons. But it won’t be an actual outsized impact on capital markets.
Edit: I should add the AI bubble can absolutely burst but there is no reason to believe these IPOs are the end of the ride. If I knew I would be…
