SpaceX stock has done what hot post-IPO stocks often do once the first burst of enthusiasm wears off: it fell back to earth. On Tuesday, the shares briefly slipped to $149 before recovering to $156, marking the first time they traded below $150 since the listing. The move answers the key question for investors watching the SpaceX stock price: the post-IPO rally is losing momentum, even if the company’s valuation remains eye-watering.
From a peak of nearly $226 on June 16, the shares have dropped almost 34%, wiping about $1 trillion from the company’s market value. SpaceX also slid from fourth place among the world’s most valuable companies to seventh, though it still sits ahead of Broadcom, valued at $1.8 trillion. That ranking shuffle is a neat reminder that even the most prized tech names can lose altitude fast when investors stop bidding like it’s a private lunch reservation.
What drove the SpaceX stock sell-off
The wider tech sector did not help. U.S. technology stocks were generally down on Tuesday, and JPMorgan attributed the caution to investors waiting for Micron Technology’s quarterly report later in the week. That kind of nervousness tends to hit richly valued names first, because there is less patience for anything that looks even slightly overextended.
Elon Musk still has room to shrug
The drop is painful on paper, but it has not knocked Elon Musk off the billionaire perch. His fortune is still large enough to keep him in the dollar-trillion club, despite a paper loss of about $41.7 billion tied to the decline in SpaceX shares. In other words, this is a setback for the market story around SpaceX, not a personal financial emergency for its owner.
How far SpaceX stock can slide from here
The bigger question is whether this is a reset or the start of a longer deflation in enthusiasm. Newly public tech names often get a fast valuation lift, then spend the next stretch proving they deserve it. If SpaceX keeps trading more like a mature giant than a fresh listing, investors may find that the easy upside has already been booked.
