SpaceX Q3 2026: First-Ever Profit of $4.4 Billion as AI Revenue Overtakes Starlink

SpaceX (Nasdaq: SPCX) reported its first quarterly profit as a public company on Tuesday, posting net income of $4.4 billion for the third quarter as revenue rose 161% to $14.6 billion, well above the $12.7 billion analysts expected, with its Super Intelligence segment overtaking Starlink's parent business to become the company's largest.

The stock rose 7.8% on Wednesday to close at $159.31, its first session after the release. Diluted earnings per share were $0.35, against consensus expectations of about $0.14. Adjusted EBITDA reached $8.8 billion, up 306% from a year earlier. TECHi's preview of the report said the quarter would be judged against the bar set in Q2, because SpaceX gives no guidance: a full quarter of its Cursor acquisition, a full quarter of interest on its $25 billion bond, and an AI capital bill that had already doubled once. On the measures the preview set, SpaceX cleared the bar — and the same release shows what the clearance cost.

The quarter against the bar Q2 set

Revenue of $14.575 billion was up 87% from Q2's $7.814 billion in a single quarter. Income from operations swung to $2.791 billion from a $143 million loss in Q2 and a $273 million loss a year earlier. The net income figure compares with a net loss of $1.054 billion in the third quarter of 2025; for the nine months to September 30, SpaceX remains $413 million in the red, because the first half's losses have not yet been fully earned back.

Segment detail from the release: Super Intelligence revenue $7.560 billion (Q2: $2.561 billion), Connectivity $5.248 billion (Q2: $4.291 billion), Space $1.767 billion (Q2: $962 million). Every segment beat the consensus figures circulating before the report, with total revenue about 15% above the $12.72 billion LSEG consensus.

Where the $4.4 billion came from

The operating business earned $2.791 billion of the $4.404 billion net income — about 63%. TECHi's calculation from the statements in the release shows the remaining $1.613 billion, roughly 37%, arrived below the operating line: $873 million of interest income, earned largely on the cash pile from June's IPO; $1.025 billion of other income, net, of which $561 million is identified as related-party; less $675 million of interest expense, of which $351 million is related-party; plus a $390 million income-tax benefit that added to, rather than reduced, the result.

None of that makes the profit artificial — interest income on a $51.3 billion cash balance is real money, and the operating swing from a $143 million loss to a $2.791 billion profit in one quarter is the genuine inflection. But the composition matters for what repeats. The related-party share of both the interest bill and the other-income line runs through the wider Musk ecosystem of companies, and the release does not break out what the $561 million related-party gain consists of. That detail, if it comes, will arrive in the quarterly 10-Q rather than the earnings release.

Super Intelligence is now the company

A year ago the segment SpaceX then called Artificial Intelligence produced $813 million, 15% of revenue. In Q2 it produced $2.561 billion, 33%. In Q3, renamed Super Intelligence, it produced $7.560 billion — 51.9% of everything SpaceX sold, more than Connectivity and Space combined. TECHi's calculation: $5.0 billion of the $6.8 billion of revenue SpaceX added versus Q2 came from SI alone, driven, the company says, by new cloud services agreements, the acquisition of Cursor — completed in August and consolidated for a full quarter for the first time — and adoption of its SI models and software, including Grok Bot.

SI also posted its first operating profit: $431 million, against a $1.257 billion operating loss in Q2 and a $1.722 billion loss a year earlier. Its operating margin, though, was 5.7%, against 45.1% for Connectivity — the satellite business remains far more profitable per dollar of revenue. And SI's expansion is capital-hungry in a way Starlink never was: the segment's capital expenditure was $16.444 billion in the quarter, 2.2 times its own revenue and 84% of the company total. Nameplate compute reached 1.7 gigawatts at September 30, up from 1.4 GW at June 30 and 0.6 GW a year earlier.

Starlink keeps compounding — at thinner prices

Connectivity revenue rose 69% year over year to $5.248 billion, with operating income up 99% to $2.367 billion. Starlink consumer subscribers reached 13.6 million at September 30, up 1.6 million in the quarter and from 7.2 million a year earlier; enterprise and government revenue within the segment was $2.127 billion. The trade-off is price: consumer ARPU was $69 a month, up from $66 in Q2 but down from $83 a year ago, as growth comes from cheaper plans and markets.

The Space segment, meanwhile, nearly broke even — an operating loss of just $7 million on $1.767 billion of revenue, against a $542 million loss in Q2. SpaceX flew 35 launches in the quarter (12 customer, 23 internal) and completed its first revenue-generating Starship mission, delivering 26 Starlink V3 satellites — about ten times the downlink capacity of a Falcon 9 Starlink launch, the company says.

The cash equation underneath

Total capital expenditure was $19.593 billion in the quarter, 134% of revenue. Across the nine months, SpaceX generated $13.097 billion of operating cash flow and spent $48.069 billion on property, plant and equipment — free cash flow of roughly negative $35.0 billion, by TECHi's calculation. The funding is not in question this year: cash and equivalents stood at $51.294 billion at September 30, and the company also bought $46.8 billion of marketable securities during the nine months, parking IPO proceeds. The open question is duration: at Q3's pace of spending, even a $51 billion cash balance plus securities is a runway measured in quarters, which makes SI's revenue durability — how much of Q3's cloud-agreement surge is recurring — the number that decides the story in Q4.

The merger question

On Tuesday's earnings call, Elon Musk said the boards of SpaceX and Tesla have formed committees to discuss a merger of the two companies, according to reports of the call, and argued there is "a lot of merit" in combining them. Wedbush's Dan Ives was reported estimating an 80% to 90% chance of a merger by the end of 2027. Nothing about a transaction is in the earnings release, and the two companies already transact with each other — the related-party interest and income lines above are part of that existing web — so investors should treat the committee news as a direction of travel, not a deal.

What to watch

Three things decide whether Q3 was an inflection or a spike. First, the 10-Q: it should detail the related-party other income, the digital-asset position ($1.573 billion at September 30, with a $64 million unrealized loss over nine months) and any colour on how much SI revenue is contracted versus one-off. Second, Q4 SI revenue: Q3 included the first full quarter of Cursor and the start of new cloud agreements; a flat or falling SI line would reframe this quarter as a step-change in level rather than in growth rate. Third, the spending line: capex has risen from $6.9 billion a year ago to $19.6 billion, and the market is now capitalising the company above $2 trillion on the assumption that the SI build-out converts to durable, higher-margin revenue before the cash pile thins.
