SpaceX Grew AI Revenue Ninefold to $7.6 Billion and Spent $19.6 Billion Doing It — the Tesla Merger Committees Are a Financing Decision

Super Intelligence revenue of $7.56 billion exceeded the $7.02 billion that Starlink and space launch produced together. The segment grew from $813 million a year earlier, and management said solutions and infrastructure revenue rose 192% sequentially excluding Cursor, driven by newly activated cloud services agreements. SpaceX bought xAI in February 2026 and renamed the unit SpaceXSI on Oct. 4; it now reports as the Super Intelligence segment.

The margin story hides in the capex line. Super Intelligence produced a 65.5% adjusted EBITDA margin, yet its reported operating income was $431 million, a 5.7% margin that absorbed $1.2 billion of Cursor-related stock compensation;a $4.5 billion wedge separates adjusted EBITDA from operating income. Across the company, depreciation of $3.64 billion and stock compensation of $2.36 billion together ran at 41% of revenue. A rented-compute business reports profit as a depreciation-schedule decision, not a cash outcome.

This was not a demand surprise from a proprietary product. Reuters and NBC News both reported that AI revenue rose more than ninefold mostly from renting out computing capacity. The renters are the same hyperscalers now spending $195–205 billion on their own data centers in 2026, according to Alphabet's own guidance, and they are the most sophisticated buyers in the market. The contracts are large, long-dated and concentrated in two counterparties.

Revenue of $14.58 billion came with operating cash flow of $9.63 billion and capital expenditure of $19.59 billion, so free cash flow was negative $9.96 billion in a single quarter. Cash and marketable securities ended September at $89.86 billion against $38.84 billion of debt, a net cash position of $51.01 billion, but the trajectory is steep: management guided fourth-quarter capital expenditure to $35–40 billion, which puts full-year 2026 spending at $83–88 billion.

The Cursor deal explains why the cash picture looks better than the cash flow suggests. SpaceX booked $42.5 billion of purchase consideration and $60 billion of implied equity value, yet investing activities show acquisitions consuming just $514 million of net cash in the quarter while additional paid-in capital rose $45.2 billion — the arithmetic signature of a deal paid largely in the company's own stock. Goodwill ended the quarter at $48.42 billion against a $37.45 billion accumulated deficit.

The market has repriced SpaceX as though the AI business deserves a software multiple. On trailing revenue the company trades at about 76 times sales and 150 times EBITDA — against 10.5 times and 20 times for CoreWeave, the listed pure-play neocloud. SpaceX's AI segment is now larger than CoreWeave's entire business and more profitable on adjusted EBITDA, yet the market pays roughly seven times the sales multiple for it.

Two things follow. First, CoreWeave is the market's prior on this asset class: 11.5 times net debt to EBITDA, negative $13.65 billion of trailing free cash flow, and a share price 56% below its 52-week high — and that is the business whose economics SpaceX is now copying with better funding. Second, depreciation intensity makes the comparison sharper. CoreWeave's trailing depreciation runs at 52.6% of revenue; SpaceX's runs at 25.0%, which deserves scrutiny rather than relief, because the gap closes as the fleet ages or reflects longer depreciation lives.

On the earnings call Elon Musk said both boards formed special committees of independent directors to examine a combination at shareholders' request, that he is recused because of his conflicts, and that no terms have been agreed. Notably, SpaceX's Oct. 20 filing with the SEC was the earnings release, not a transaction disclosure: no merger agreement, no special-committee report. For a company of this size, a signed deal would have produced its own filing. What investors hold is a committee process, not a deal.

Put those facts beside the cash numbers and the committees read differently. SpaceX is not liquidity-constrained: $89.86 billion of cash and securities covers the guided fourth-quarter build more than twice over. What is constrained is the price of equity, at a moment when the stock sits about 30% below its 52-week high and before the Dec. 8 unlock puts a large block of paper into the market. SpaceX is separately arranging a reported $40 billion GPU purchase with Apollo Global Management and banks. A combination with Tesla would supply public equity currency — a $1.53 trillion market capitalization against $16.4 billion of cash and $5.76 billion of trailing free cash flow — and would clear a related-party conflict that forced independent committees in the first place. The committees are the cheapest financing SpaceX has been offered.

The pattern is a textbook build-out: the chip vendor and the arrangers of the debt are paid first, the landlord of compute collects the rent, and the balance sheet keeps the depreciation. NVIDIA has the cleanest exposure because it is paid when the chips ship, not when the fleet is paid for; SpaceX's segment capex of $16.44 billion in a single quarter is roughly 80% of what CoreWeave spent on equipment in all of the trailing twelve months. The tenant side is where the squeeze lands: with Alphabet guiding to $195–205 billion of its own 2026 capital expenditure, renting from SpaceX is a rounding error for Google and an existential question for the neoclouds.
