A symbolic line crossed on a fourth straight losing day

SpaceX shares closed at $135.27 on Wednesday, July 15, 2026, briefly dipping as low as $132 to $134.50 during the session — the first time the stock has traded below its $135 initial public offering price since the company's historic Nasdaq debut on June 12. It marked SpaceX's fourth consecutive down session, and it arrived just one month after a listing that had, at the time, been celebrated as the largest IPO in history.

The symbolism matters more than the specific dollar figure. Falling below the offering price means that anyone who bought SpaceX shares at the IPO itself — rather than during the subsequent trading frenzy that pushed the stock considerably higher — is now sitting on a paper loss for the first time since the company went public. That's a notable psychological threshold for a stock that, barely a month ago, was being discussed as evidence of unstoppable investor enthusiasm for Elon Musk's combined rocket, satellite, and AI business.

How far the stock has actually fallen

The scale of the reversal is considerable. SpaceX shares peaked at roughly $214 to $225 on June 17, just days after their debut, pushing the company's valuation as high as $2.6 trillion — briefly above the market capitalizations of both Amazon and Microsoft. As of Wednesday's close, the stock sits more than 34% below that peak, and the company's market capitalization has fallen to somewhere between $1.75 trillion and $1.79 trillion, depending on the exact closing price used, wiping out more than $800 billion in paper value from the high.

That's an unusually dramatic round trip for a company barely a month removed from what was, by any measure, a wildly successful public debut. SpaceX stock had climbed more than 40% in its first two trading sessions alone, at one point pushing its valuation above both Amazon's and Microsoft's, before a sharp single-session reversal knocked it down 16% and set the broader retreat in motion.

The Nasdaq-100 boost that didn't hold

Part of what makes this decline notable is that it happened despite, not because of, one of the more favorable structural tailwinds a newly public stock can receive. SpaceX joined the Nasdaq-100 index just last week, qualifying under a recently adopted "fast-track" rule that cuts the standard waiting period for newly public companies from the usual seasoning requirement down to just 15 trading days. That inclusion channeled a wave of mechanical, passive buying into the stock, as every index fund tracking the Nasdaq-100 was required to purchase shares to match the benchmark's new composition.

That demand proved short-lived. Within a single trading session of its Nasdaq-100 debut, SpaceX had already surrendered the $150 per share level at which it first began trading following the index inclusion — evidence that whatever mechanical buying pressure the index inclusion generated wasn't enough to offset the broader selling pressure building against the stock from other directions.

What's actually driving the retreat

Several distinct factors appear to be compounding against SpaceX simultaneously, according to market analysts tracking the decline. Daniela Hathorn, senior market analyst at Capital.com, told Reuters that the selloff reflects investors locking in gains after the stock's dramatic initial run-up, a broader reassessment of what had become an extremely rich valuation, and the unwinding of heavily bullish positioning that had built up around one of the most hyped listings in market history.

The company's underlying financials give reassessment-minded investors real substance to work with. SpaceX posted a net loss of $4.9 billion in 2025 and lost an additional $4.28 billion in just the first quarter of 2026 — considerable and continuing losses for a company now trading at a price-to-sales ratio of roughly 70, according to figures from GuruFocus. That's an extraordinarily rich multiple even by the standards of high-growth technology companies, and it leaves the stock with very little valuation cushion if investor sentiment continues souring or if growth expectations get pared back even modestly.

Broader AI-financing anxiety isn't helping

SpaceX's troubles aren't occurring in isolation from the rest of the market. Reuters reporting connected part of the selloff to broader anxieties about the heavy borrowing being used across the technology sector to finance AI infrastructure buildouts, combined with concern about how continued Federal Reserve interest rate moves might pressure richly valued technology stocks generally. SpaceX itself raised $25 billion in the bond market last month specifically to fund its own technology infrastructure buildout — a debt load that becomes more expensive to service, and riskier to carry, if rates move higher or if the AI capital-spending cycle broadly starts to show cracks.

That backdrop matters because it means SpaceX's decline isn't purely a company-specific story about slowing enthusiasm for reusable rockets. It's unfolding alongside a broader market conversation about whether the enormous capital expenditure commitments technology and AI infrastructure companies have made over the past year are sustainable at current financing costs — a question that's been weighing on numerous other high-multiple growth stocks in recent weeks, independent of SpaceX's own specific fundamentals.

Why one analyst says this stock moves the whole market's mood

Steve Sosnick, chief market analyst at Interactive Brokers, offered a framing that goes beyond SpaceX's own balance sheet: the decline illustrates just how closely the broader market is watching this particular stock, and how disproportionately much weight it now carries in shaping overall investor sentiment. "There hasn't been anything lately to remind people of some of the catalysts for why they bought SpaceX," Sosnick said — a comment suggesting the stock's recent weakness reflects less a specific negative catalyst than an absence of fresh positive news to sustain the initial hype that drove the run-up in the first place.

That absence-of-catalyst framing puts real weight on what happens next. SpaceX's thirteenth Starship test flight is scheduled for Thursday, July 16, with a 90-minute launch window opening at 6:45 p.m. Eastern from the company's Starbase, Texas facility. Engineers have reportedly made targeted fixes following issues from the twelfth flight, including reworking the ignition sequence after a timing problem caused the Super Heavy booster to flip roughly 90 degrees off course during stage separation on the previous attempt. A clean, successful test could give the stock exactly the kind of positive catalyst Sosnick suggests has been missing. Another visible failure, on the other hand, would arrive at a moment when the stock has already lost more than a third of its value and investor patience for setbacks may be considerably thinner than it was immediately after the company's record-breaking debut.
