Analysis
Two of 2026's largest and most closely watched tech IPOs have taken opposite paths since their debuts, offering a real-time lesson for every company still weighing a public listing this fall.
Cerebras: A Historic Pop, Then a Round Trip
Cerebras priced its IPO at $185 a share in May, and the stock opened trading at $350 -- more than double its offer price, the largest tech IPO pop of the year at the time. Since then, the stock has traded through real volatility: it reached an all-time high of $386.34 on May 14, its opening day, then fell to an all-time low of $160.81 by late June, before stabilizing in a range around $185 to $190 in early September -- essentially back to its original IPO price after a round trip through both a historic pop and a subsequent crash tied to earnings results. Cerebras currently carries a market capitalization of roughly $45 billion.

SpaceX: A Deeper Drop, Then a Partial Rebound
SpaceX took a similar round trip on a different timeline. It priced at $135 a share in June and closed its first trading day near $161, but by summer it had fallen as low as $104.83 -- a 52-week low that sits below its own IPO price, a steeper drawdown in percentage terms than Cerebras ever saw. The stock has since clawed back roughly 19% over the past four weeks to trade around $150 in early September, helped by Oppenheimer raising its price target to $280 from $250 on Sept. 2, but it remains below its first-day close of $161. That's not the durable climb it can look like at a glance from the recent four-week chart alone -- it's a slower-motion version of the same pop-and-drawdown pattern Cerebras went through, just with a deeper trough and an earlier recovery underway.
What the Pattern Says About 2026 IPO Pricing
Unitree Robotics adds a third data point to the same lesson: its IPO priced around a $9 billion valuation and the stock surged 460% on opening day -- an even larger first-day pop than Cerebras -- which by itself tells a prospective investor almost nothing about where the stock trades six months later. Across all three of 2026's marquee tech listings, first-day performance has been a weak predictor of aftermarket durability. Cerebras and Unitree both had the biggest headlines on day one; SpaceX priced more conservatively and still fell below its own IPO price within weeks -- proof that a smaller pop doesn't buy immunity from a real drawdown, either.
Why This Matters for the Pipeline Still to Come
Oura just filed for an IPO targeting a $16 billion-plus valuation, and Crusoe is reportedly meeting IPO bankers off the back of a fresh $30 billion private mark. Both companies, and every other name still in the 2026 IPO pipeline, are effectively choosing which pattern they'd rather bet on: a Cerebras-style pop that generates the bigger initial headline but risks an equally sharp reversal once lockups and first-earnings scrutiny arrive, or a SpaceX-style conservative opening that still isn't immune to a double-digit-percent drawdown of its own, just spread out over a longer runway and a deeper trough.
The Counterweight
None of this is fully settled yet -- Cerebras's current price near its IPO level could just as easily be a floor before the next leg up as it could be a ceiling on a stock that already had its best days on opening morning, and SpaceX's recent bounce off its $104.83 low could just as easily fade if the Oppenheimer upgrade proves premature, especially since the stock still hasn't reclaimed its own first-day close of $161. Six months of trading history is not the same as a multi-year track record, and every one of 2026's IPO class is still young enough that today's pattern is a data point, not a verdict.
Cerebras's next earnings report will be the real test of whether its price has actually stabilized or is simply pausing before another move in either direction.
