SpaceX's $35 Billion Funding Gap Tests the Economics of Its AI Land Grab

SpaceX has never had trouble convincing investors it can grow. The harder question, and the one now moving to the front of the debate, is whether the capital pouring into its AI buildout comes back.

Forbes Japan has put a number on the mismatch: across the first nine months of 2026, capital expenditure reached $48.1 billion against an operating cash flow of $13.1 billion — a $35 billion shortfall. That figure, rather than the adjusted profit line, may be the more telling gauge of where the company stands.

The distinction matters because a rising operating result and a heavy funding need can travel together. SpaceX's third quarter of 2026 delivered a net profit of $4.4 billion and adjusted EBITDA of $8.8 billion, while capital spending ran to $19.6 billion in the same three months. Those metrics measure different things and cannot be netted against one another, but together they explain why a profitable quarter is not, on its own, an all-clear. On this reading, SpaceX is less a story of proven earning power than a wager on how productively an enormous capital base can eventually be put to work.

The Payback Promise Is the Pivot

Chief financial officer Bret Johnsen expects capital expenditure of $35–40 billion in the fourth quarter of 2026, and has said new computing capacity should pay for itself in under a year at current prices. That claim is the economic hinge on which the whole strategy turns. If it holds durably, the aggressive buildout looks far more defensible; the qualifier "at current prices" is what makes it fragile, since a payback calculation struck today says nothing certain about capacity delivered later. Investors would do well to treat it as a testable company assumption rather than a guaranteed return.

The AI segment illustrates the tension. Forbes Japan reports that $16.4 billion of third-quarter 2026 capex went to AI, while the AI business booked an operating loss of $3.3 billion over the first nine months of 2026. None of that invalidates the long-term plan, but it shows that revenue growth and operating profitability have yet to move in step. Operating cash flow, in that light, carries more signal than an adjusted earnings figure viewed in isolation — depreciation and running costs belong in any honest assessment of a capital-intensive infrastructure play.

Should investors sell immediately? Or is it worth buying SpaceX?

A $40 Billion Chip Lease, and a Carrier Ambition

The scale of the financing machinery behind that buildout became clearer with a binding commitment for a master financing lease of roughly $40 billion, arranged with a unit managed by Apollo Global Management. The deal covers graphics processing units and related equipment, with closing targeted before year-end subject to customary conditions. Elon Musk said on Sunday that $40 billion of debt financing for GPUs had been secured.

A space company mobilising sums of that order for high-performance silicon marks a genuine shift in the technology landscape, one in which computing power and orbital data networks merge and the lines between telecoms, cloud computing and spaceflight simply dissolve. The expansion also reaches down to earth: according to media reports, SpaceX is seeking access to at least 80,000 mobile sites to build its own carrier, negotiations the company has not confirmed but which fit the picture of an all-encompassing communications network.

Profit, Upgrades and a Merger in the Wings

The investment plans land alongside an operating performance that has changed dramatically. Quarterly revenue climbed 161% year on year to $14.6 billion, and the bottom line swung from a net loss of $1.1 billion a year earlier to the $4.4 billion profit. Adjusted EBITDA rose 306% to $8.8 billion — evidence of an earnings engine emerging from a costly research and buildout phase, one able to absorb heavy upfront spending.

That momentum is forcing sceptics to rethink. PhillipCapital upgraded the stock from Sell to Buy on Friday and lifted its price target from $75 to $250. Bernstein, for its part, raised its target to $268 a day earlier while reaffirming its positive rating, modelling full-year 2028 revenue of $424 billion without assuming either a Tesla merger or a cell-tower contract. Even so, a revenue model does not answer how much capital gets tied up along the way, or what sustainable cash flow emerges.

Structural questions are in play too. Musk said boards of both SpaceX and Tesla have formed special committees to explore a possible combination; no terms have been agreed, and any transaction would need approval from the special committee, the board and the majority shareholder. The committee has made no determination.

In Monday trading the stock stood at €132.60, a market capitalisation of about €1,971.01 billion and 32% below its 52-week high of €194.46. Access to capital is an advantage — but it is not proof that every additional facility earns its keep. The convincing next step would not be more revenue or another financing round; it would be evidence that the new computing capacity reliably returns the money SpaceX is committing at such pace.
