SpaceX spends $18.4B in a single quarter, and investors are not convinced

SpaceX just posted its first full earnings report as a public company, and the numbers tell two very different stories at once. Revenue nearly doubled. Capital expenditure exploded by more than six times. Investors, apparently, focused on the second part.

After-hours trading following the announcement saw SpaceX shares fall between 7% and 12%, a pointed signal that Wall Street is not simply impressed by growth when the bill for that growth is this large.

The numbers, laid out plainly

For the quarter ended June 30, 2026, SpaceX reported $7.8 billion in revenue, a 92% increase compared to the same period a year earlier.

At SpaceX, it was overshadowed by $18.4 billion in capital expenditures during the same three months. To put that ratio in perspective: the company spent roughly $2.36 for every $1 it brought in.

Of that $18.4 billion in capex, $15.8 billion went toward artificial intelligence infrastructure. One year earlier, total capex for the equivalent quarter was $2.8 billion.

The net loss for the quarter narrowed to $541 million. Adjusted EBITDA came in at $3.5 billion.

Starlink, the satellite internet division, contributed $4.3 billion of the $7.8 billion in quarterly revenue, making it the company’s clearest proof point for durable, recurring income.

The IPO context matters here

SpaceX completed its initial public offering in June 2026, with the transaction valuing the company at between $1.75 trillion and $1.8 trillion.

Post-IPO, the company held approximately $93.5 billion to $100 billion in cash and marketable securities, a war chest built in part through a $25 billion bond issuance that accompanied the public offering.

What the spending is actually buying

The $15.8 billion directed toward AI infrastructure represents a strategic pivot that goes well beyond SpaceX’s identity as a rocket company. Elon Musk has been vocal about the convergence of space, AI, and computing, and the capex numbers now reflect that ambition in concrete dollar terms.

Starlink’s $4.3 billion quarterly contribution is the clearest validation that at least one of those arms is working. A subscription-based revenue stream tied to satellite connectivity is relatively predictable, and that predictability becomes more valuable as the rest of the business remains in investment mode.

The $25 billion bond issuance and the cash pile from the IPO give SpaceX the runway to keep spending without an immediate liquidity crisis.
