SpaceX Shares Slide as Investors Question the Cost of Its Expanding AI Ambitions

05 August 2026

SpaceX is promising unusually fast returns from its aggressive push into artificial intelligence, but investors are not yet convinced that the enormous spending required to build its AI infrastructure can be sustained. Shares of Elon Musk’s space and satellite company fell sharply following its first earnings call as a publicly traded business, highlighting growing Wall Street concerns about whether rapid AI expansion will ultimately justify its extraordinary costs.

SpaceX shares dropped about 12 percent, pushing the stock well below its $135 initial public offering price less than two months after its blockbuster market debut. The decline came despite the company reporting strong growth in its emerging artificial intelligence business and revealing billions of dollars in new cloud computing contracts.

The central concern is capital spending. SpaceX spent approximately $18.4 billion on capital expenditures during the second quarter, including $15.8 billion devoted specifically to AI infrastructure. That quarterly total represents more than one fifth of the $85.7 billion the company raised through its June IPO.

The spending has left SpaceX deeply negative on free cash flow as it simultaneously invests in artificial intelligence infrastructure, Starship production and next generation Starlink satellites.

Management, however, argues that the economics behind its AI expansion are improving much faster than investors expected. Chief Financial Officer Bret Johnsen said new computing investments are currently generating a payback period of less than one year, considerably faster than traditional data center projects that can require several years to recover their initial costs.

SpaceX also disclosed that its AI business generated $2.6 billion in second quarter revenue, more than tripling from the previous year. The operation remains unprofitable on an operating basis, but executives believe growing demand could eventually allow the AI division to finance its own expansion.

That possibility received another boost from $6.7 billion in additional cloud computing contracts signed since the end of the second quarter. SpaceX expects its computing capacity to exceed two gigawatts by the end of 2026 and is targeting a $100 billion annualized revenue run rate by year end.

For investors, the debate increasingly centers on whether those ambitious growth targets can keep pace with spending.

Starlink has traditionally been viewed as the profitable engine capable of funding SpaceX’s more expensive ventures. Management is now attempting to convince Wall Street that artificial intelligence infrastructure itself can generate enough revenue to support future investment rather than depending indefinitely on Starlink’s cash flow.

The company has no immediate plans to slow down. Capital expenditures during the next two quarters are expected to remain around second quarter levels as SpaceX continues expanding its computing infrastructure and satellite network.

Analysts remain divided. Supporters point to enormous demand for AI computing and the unusually rapid monetization of new capacity as evidence that SpaceX could build another major business alongside Starlink. Skeptics argue that maintaining such extraordinary spending requires near flawless execution and continued demand.

That tension explains the sharp market reaction. Investors increasingly want technology companies to demonstrate clear financial returns from their enormous AI investments, and SpaceX is now facing the same scrutiny.

The company’s early results suggest its AI ambitions have significant potential. For Wall Street, however, the question is no longer whether SpaceX can build enormous computing infrastructure. It is whether the revenue can grow quickly enough to justify the billions required to keep building it.
