SpaceX’s first quarter as a public company came with a startling split-screen: revenue surged 92% to $7.8 billion, but shares still fell about 7% to 8% after the company revealed an $18.4 billion spending surge, including nearly $16 billion tied to xAI and AI. The selloff shows what Wall Street is focusing on now that Elon Musk’s rocket and satellite business is no longer a private story: growth is no longer enough unless investors can see a path to returns that justify the bill.
The numbers themselves were strong by almost any measure. SpaceX said second-quarter revenue rose from the prior year to beat the $6.81 billion analyst consensus, while its net loss came in at $541 million, far better than the $1.9 billion loss analysts had expected. Starlink revenue grew 66% year over year, and the AI segment posted 247% growth. But those figures were overshadowed by the size and direction of the spending, which appears to have become the main market story.
The market reaction was immediate. SpaceX shares slid in after-hours and postmarket trading on August 4 after the earnings release, according to multiple reports, even though the company’s top line beat expectations. The stock was already under pressure before the report, down about 49% from its June 2026 high of $225.64 and below its $135 IPO price, Proactive Investors reported. In other words, investors entered the print with a lot of doubt already baked in, and the quarter did little to ease it.
At the center of the backlash is capital expenditure. SpaceX said quarterly capex reached $18.4 billion in the second quarter, well above the roughly $13 billion analysts had estimated. Nearly $16 billion of that went to the xAI and AI segment, underscoring how aggressively Musk is folding artificial intelligence into the company’s future. SpaceX merged with Musk’s xAI in February 2026, integrating AI into the company before the IPO, according to Moneyweb and CNN. That combination may excite believers in Musk’s ecosystem strategy, but it also means investors are now financing a much larger and less familiar buildout.
Luke Lango, technology analyst and publisher of Innovation Investor, summed up the market’s mood in a quote to CNN and Yahoo Finance: “The stock’s negative reaction is less a rejection of the fundamentals than a reflection of the enormous price of growth. Investors are demanding clearer evidence that its extraordinary growth can ultimately generate returns commensurate with its extraordinary spending and valuation.” That framing captures the core tension. SpaceX is still growing fast. The question is whether the company is now spending faster than shareholders can tolerate.
Musk, for his part, leaned into the long game. On the analyst conference call, he said, “We expect the cadence of AI development to improve dramatically.” He also told investors, “Our internal projections for reaching a trillion dollars in revenue…have moved up from 2031 to 2030. And there’s a non-zero chance of that being in 2029.” Those comments fit Musk’s usual style: bold, timeline-driven, and designed to keep the story pointed at a much larger future. They also raised the bar for evidence.
This earnings release is not being judged like a normal utility-style growth update. Investors are trying to price a company that now combines launch, broadband, AI and Musk’s broader ecosystem ambitions in one public vehicle. The result is a valuation debate that looks less like a quarterly scorecard and more like a referendum on whether Musk can keep creating new growth engines without overextending the balance sheet or the share price.
The concern is not that SpaceX failed to grow. It is that the company grew while spending at a scale that changes the whole financial model. Revenue nearly doubled, losses narrowed sharply, and the AI and Starlink businesses both accelerated. Yet the market still sold the stock. That suggests investors are separating operating performance from capital intensity and deciding that the second number matters more right now.
That tension is especially sharp because the company’s AI exposure is no longer abstract. Nearly $16 billion of capex was directed to the xAI/AI segment in the quarter, a figure that dwarfs what many investors would associate with a satellite-and-space operator. Even if the business eventually proves more valuable because of the AI layer, the near-term cost is clear. That is why the quarter landed less like a celebration of scale and more like a warning about how expensive that scale may become.
There is also a calendar risk. A lockup expiration on Thursday, August 6, will free 911.5 million shares, or about 12% of the company, worth roughly $116 billion, for sale by early investors and employees, according to Proactive Investors and CNN. Another 455.8 million shares can unlock around August 20, with additional expiries scheduled through September and beyond. That matters because stock pressure from the earnings reaction could meet a new wave of potential supply almost immediately.
The timing increases the stakes for both bulls and bears. If shareholders who have been waiting for liquidity decide to sell into weakness, the market could treat the earnings report as the opening act rather than the final word. If insiders and early backers hold their positions, the supply overhang may prove less severe than feared. Either way, the lockup puts a hard deadline on the market’s ability to digest the new valuation story.
For now, the message from the tape is simple. SpaceX can beat revenue estimates, cut losses far more than expected, and still be punished if investors think the next phase of growth will be too expensive. That is the kind of reaction usually reserved for companies trying to prove they can scale without burning through capital. With Musk’s AI push now welded into the business, the burden is even heavier: the company has to show not just speed, but discipline.
The next few sessions should tell traders whether the selloff was a reflex to a huge capex number or the start of a broader reset in how the market values Musk’s most ambitious public company. Either way, the August 6 lockup expiry now looks like the next catalyst to watch.
