Ask HN: OpenAI, SpaceX/xAI, Anthropic all to IPO, is this a sign of the peak?

My question is to people far more experienced in this world and familiar with the behavior of investors and startups -> IPO.

Given the leaks recently that they’re all aiming for an IPO asap, is this a strong signal that their investors feel this is the peak of their valuation for the near if not indefinite future?

I understand it’s impossible to know anything for sure, least of all how the market will react regardless of the motivations of these players, but I’m curious to get some perspectives.
