SpaceX's Capital Spending Was 2.4 Times Its Revenue Last Quarter. The IPO Left $93.5 Billion to Cover It.

Written by Daniel Sparks for The Motley Fool

SpaceX's second-quarter capital spending of $18.37 billion was more than double its $7.81 billion of revenue.

Cash and equivalents ended June at $93.5 billion, lifted by about $85.7 billion of IPO proceeds.

Operating cash flow covered about 12% of the company's capital spending in the first half of 2026.

SpaceX(NASDAQ:SPCX) spent $18.37 billion on capital projects in the second quarter. It booked $7.81 billion of revenue. For every dollar of that, about $2.35 went out for data centers, chips, satellites, and rockets. That ratio was deliberate.

What makes the arithmetic possible is the balance sheet June's initial public offering (IPO) built. SpaceX ended the quarter with $93.5 billion of cash and equivalents, up from $24.7 billion at the end of last year.

The offering raised about $85.7 billion in net proceeds, and a debut bond sale in late June raised $25 billion more, most of which repaid a bridge loan.

So the money exists. How long does it last at this pace of spending, and what takes over when it runs low?

A year ago, SpaceX spent $2.8 billion on capital projects in a quarter. In this year's first quarter, it spent $10.1 billion. Last quarter's $18.37 billion was a more than sixfold jump from a year earlier, and nearly double the quarter before.

Of the latest total, $15.83 billion went to artificial intelligence (AI) infrastructure, the data centers and chips behind the company's expanding cloud platform. The rockets and satellites SpaceX is known for accounted for about $2.5 billion combined.

Sure, revenue is climbing fast too, up 92% year over year to $7.81 billion, with AI segment revenue up 247% year over year to $2.6 billion on new cloud computing contracts. But spending is climbing faster. The gap between capital outlays and revenue widened to about $10.6 billion last quarter, from about $5.4 billion in the first quarter.

Cash flow tells the cleanest story. Through the first half of 2026, SpaceX's operations produced about $3.5 billion of cash, while capital spending ran $28.5 billion.

In other words, the business funded about 12% of its own build-out. The balance sheet funded the rest.

The profit base underneath is, I'd argue, narrower than the revenue growth makes it look. Starlink's connectivity segment produced $1.7 billion of operating income last quarter, up 79% year over year, and it remains the only segment running at a profit. The AI segment cut its operating loss to $1.3 billion, 49% smaller than the first quarter's, and swung to positive non-GAAP (adjusted) EBITDA of $1.1 billion. Companywide, the net loss narrowed to $541 million from $1 billion a year earlier.

Set the cash against the spending, and the arithmetic is quick. At the second quarter's pace, $93.5 billion covers about five quarters of capital projects. Add what operations currently generate, and it stretches to just under six.

Those five quarters assume the pace holds, and the company's own capacity targets say it can't for long.

After all, SpaceX ended June with 1.4 gigawatts of computing capacity, up from 1 gigawatt three months earlier. On the Aug. 4earnings call the company said it expects more than 2 gigawatts by the end of 2026, and closer to 10 gigawatts than 5 by the end of 2027. Building toward that means capital expenditures grow before long.

Management's defense is that the AI spending pays back unusually fast.

"All capex is not the same," said chief financial officer Bret Johnsen on the call. "Specifically on the AI compute side, we're able to deploy capital in such a way that we're getting less than a one-year payback."

And to be fair, there is contracted revenue behind the claim. SpaceX signed $14.1 billion of cloud services agreements during the quarter.

Johnsen said the company added another $6.7 billion of cloud contracts in the first weeks of the current quarter, and that SpaceX expects to reach a $100 billion annualized revenue run rate by the end of the year -- a target that counts the newly acquired Cursor along with the cloud deals. If deals keep landing at that rate, the gap the balance sheet has to cover could shrink quickly.

But if they don't, the alternatives are more borrowing or more stock, and SpaceX is already using both: it sold $25 billion of bonds in late June, and it paid for Cursor, the AI coding company, entirely in newly issued shares -- a $60 billion deal that closed Aug. 14.

Ultimately, the IPO bought time, not a finished transition. The stock, around $146 as of this writing, values SpaceX near $1.9 trillion -- roughly 60 times its annualized second-quarter revenue. A valuation like this arguably treats the shift to self-funding as nearly done.
