Look across the last six weeks of 2026's IPO calendar and a pattern emerges that's easy to miss story by story: this isn't one IPO market reopening, it's two very different markets running in parallel, and only one of them is actually hot.
At one extreme, SpaceX raised $75 billion in June at a $1.77 trillion valuation, the largest IPO in history, and Cerebras raised its price range twice before ultimately pricing at $185 a share -- above even its raised $150-$160 band -- and popping 108% on debut to a $5.5 billion raise. Those are AI-infrastructure names being priced with almost no visible ceiling, on the logic that compute capacity is the scarcest input in the entire economy right now.
“Lime's $174 million raise at a $1.7 billion valuation opened up just 8% -- a respectable but unremarkable debut for a real, profitable-adjacent consumer business.”
At the other extreme, more conventional listings are landing at a completely different scale and multiple. Lime's $174 million raise at a $1.7 billion valuation opened up just 8% -- a respectable but unremarkable debut for a real, profitable-adjacent consumer business. Bending Spoons' $1.68 billion raise and 40% first-day pop looks stronger on the surface, but it's still priced at software-industry multiples, not the open-ended AI premium.
This week's IPO pipeline makes the split visible inside a single seven-day stretch: SK Hynix is bookbuilding a $28.13 billion AI-memory offering with cornerstone investors lined up for $7 billion, while Standard Nuclear -- power infrastructure adjacent to the same AI buildout -- is targeting just $355.9 million on a conventional 18.25-million-share offering. Both are legitimately AI-adjacent; only one is being priced like it.
For founders and boards planning a 2027 listing, the takeaway isn't that "the IPO window is open" in some general sense -- it's that there are effectively two windows, and which one you're walking through depends entirely on whether public investors read your growth story as AI infrastructure or as everything else. The gap between those two windows, if anything, appears to be widening rather than closing as 2026 goes on.
