SpaceX closed down for a second consecutive session Wednesday, erasing most of the gains accumulated since its record $135 IPO one month ago and raising questions about whether the Nasdaq-100 inclusion last week marked a local top rather than a catalyst for sustained institutional accumulation.
The stock traded as high as $162 in the five sessions following its March listing—a 20% premium to the fixed IPO price Elon Musk's team announced weeks before the deal priced. That early rally pulled forward demand from retail accounts and momentum funds betting on post-listing scarcity. The Nasdaq-100 addition on April 14 triggered an estimated $4.2 billion in passive index buying over a three-day settlement window, briefly lifting the stock to $158 intraday. Two sessions later, the bid disappeared.
The reversal follows a pattern visible in other mega-cap IPOs that entered major indices within weeks of listing. Passive funds execute their index-matching buys in a compressed window, often absorbing supply from early investors who treat the inclusion as a distribution event rather than a long-term entry point. SpaceX insiders and pre-IPO shareholders were subject to a modified 90-day lockup with carve-outs for up to 15% of holdings after Nasdaq-100 inclusion. That carved-out supply is now meeting a market without the passive bid that absorbed it last week.
The company's decision to fix its IPO price at $135 weeks in advance—bypassing the traditional bookbuilding process—removed a price discovery mechanism that typically calibrates supply and demand before listing day. That unorthodox structure created information asymmetry: early buyers didn't know if they were paying a market-clearing price or leaving money on the table. The initial 20% pop suggested underpricing. The current return to $137 suggests the opposite.
Space sector comps have not helped. Rocket Lab and AST SpaceMobile both traded down 8% and 11% respectively over the past two weeks as sector rotation out of speculative industrials accelerated. SpaceX's dual exposure to launch services and artificial intelligence infrastructure—Musk has emphasized the company's role in deploying satellite-based compute clusters—positioned it as a hybrid play, but that narrative has not yet translated into premium valuation support during this drawdown.
Allocators should monitor the 90-day lockup expiration on June 14, when the remaining 85% of pre-IPO shares become eligible for sale. If the stock remains near IPO price at that point, secondary supply could overwhelm buy-side demand absent a catalyst. The company reports its first post-IPO earnings on May 8. Analysts expect $6.2 billion in quarterly revenue, but guidance on Starship production cadence and DoD contract renewals will matter more than the backward-looking print.
The next technical test is $135. If that level fails, the stock enters price discovery below its IPO reference point with no prior trading support until pre-listing private market transactions in the $118–$125 range from Q4 2024.
