SpaceX Q3 Profit Hits $4.4 Billion as AI Revenue Surges

Revenue rose 161% to $14.6 billion as Super Intelligence overtook Starlink, but a $35 billion to $40 billion fourth-quarter capex plan keeps the funding question at center stage.

Key Takeaways

• Super Intelligence revenue reached $7.56 billion, more than half of group sales, as cloud compute contracts ramped and Cursor contributed $608 million in its first six weeks.
• Net income of $4.4 billion exceeded operating income of $2.8 billion, lifted by interest income, $1.0 billion of other income and a tax benefit that investors should not annualize.
• Shares rose as much as 8% after hours on the beat and first-quarter 2027 revenue guidance of $33 billion to $37 billion, ahead of a large lock-up release later this week.

From Launch Provider to Compute Landlord

SpaceX’s second report as a listed company read less like the accounts of a rocket maker than those of a cloud provider that also happens to dominate orbital launch. Revenue for the three months to September 30 reached $14.58 billion, up 161% from $5.58 billion a year earlier and 87% above the $7.81 billion booked in the second quarter, according to the earnings release furnished to the SEC on Form 8-K. It was the first quarter to reflect a full three months of capital raised in June, when the company priced the largest initial public offering on record at $135 a share. The Super Intelligence segment, the name SpaceX now uses for the former xAI business absorbed in February, generated $7.56 billion, or 52% of group sales. A year ago it contributed $813 million.

The bottom line moved with similar force. Net income was $4.40 billion, or $0.35 per diluted share, against a loss of $1.05 billion a year earlier, making this the first profitable quarter since the June listing. Adjusted EBITDA rose 306% to $8.81 billion. Consensus had clustered around $12.6 billion to $12.9 billion of revenue and roughly 14 cents of earnings, depending on the compiler. The scale of the beat matters less than its composition. Nearly all of the upside came from rented compute, a business that barely registered inside SpaceX a year ago and whose economics rest on a market that management itself describes as acutely short of supply.

Compute Moves to the Center

Within the segment, solutions and infrastructure revenue climbed to $7.02 billion from $2.19 billion in the second quarter. Cursor, the AI coding company acquired on August 14 at an implied equity value of $60 billion, added $608 million; excluding it, the line still grew 192% sequentially as new cloud services agreements went live. Nameplate compute reached 1.7 gigawatts at quarter end, up from 1.4 gigawatts in June. Chief financial officer Bret Johnsen told analysts that new deployments are earning back their cost in under a year, with pricing tracking slightly above the top of the $30 to $50 per watt range cited last quarter. The software layer is beginning to contribute as well: Grok Bot, launched in August, counted 800,000 paid weekly users earlier this month, while advertising, the legacy of the X platform, grew 19% to $538 million.

Reported profitability is thinner than the EBITDA line implies. The segment earned $431 million at the operating level after $1.22 billion of share-based compensation tied to Cursor, and the release attributes $23.4 billion of acquisition equity to post-deal service, which Johnsen said vests over roughly three years. Spread evenly, that is close to $2 billion a quarter of non-cash expense for some time to come. Elon Musk added that SpaceX prefers short-term rentals at spot rates, on the view that the value of compute per watt will rise as models improve. In a tight market, that stance captures upside. It also leaves revenue more exposed than long-dated contracts would if supply catches up with demand.

Starlink Still Carries the Margin

Connectivity remains the most dependable earner. Revenue rose 69% to $5.25 billion, operating income nearly doubled to $2.37 billion and segment adjusted EBITDA reached $3.50 billion. Consumer subscribers reached 13.6 million, against 7.2 million a year earlier, while enterprise and government revenue grew 91% to $2.13 billion on aviation installations and the Starshield program. More than 3,800 aircraft now carry Starlink, and Starlink Mobile passed 22 million monthly users. Monthly consumer ARPU of $69 improved 5% sequentially but sits well below the $83 recorded a year ago, a sign that volume rather than price is doing the work.

Two qualifications apply. The segment’s 55% gross margin included a one-time benefit of about three percentage points, mainly from tariff refunds, and Johnsen guided group gross margin in the fourth quarter back toward second-quarter levels. The capacity story is more constructive. Starship Flight 14, the vehicle’s first orbital flight, delivered 26 Starlink V3 satellites carrying roughly ten times the downlink capacity of a Falcon 9 Starlink launch, and on October 8 SpaceX agreed to acquire up to 14 megahertz of paired 800 MHz spectrum, expected to close in the first half of 2027, to support a U.S. mobile service. The Space segment itself grew only 6% to $1.77 billion despite 35 launches against 44 a year earlier, and posted a $7 million operating loss as Starship research and development absorbed $1.23 billion. Its order book is deepening, with 18 new National Security Space Launch missions and three additional NASA crew flights signed, while a Louisiana spaceport is targeted for a first launch in 2029.

The Price of the Build-Out

Capital expenditure was $19.59 billion in the quarter, of which $16.44 billion went to Super Intelligence, taking nine-month spending to $48.07 billion against operating cash flow of $13.10 billion. Management now expects fourth-quarter capex of $35 billion to $40 billion as capacity in Memphis and Southaven moves toward 2.5 to 3 gigawatts by year end, which would put full-year spending between roughly $83 billion and $88 billion. Musk said he is highly confident of adding 10 gigawatts in 2027, and he set out a chip road map running from a test device in mid-2027 to volume output at the planned Terafab site in the third quarter of 2028, dates he himself called aggressive. Formal guidance remains narrower: first-quarter 2027 revenue of $33 billion to $37 billion, and a reiterated target of $100 billion in annualized revenue based on December. His suggestion of $500 billion to $1 trillion in annual recurring revenue by the end of 2027 is aspiration, not guidance, and should be read accordingly.

The balance sheet can absorb the near term. SpaceX held $51.29 billion of cash and $38.56 billion of marketable securities at September 30, against $38.84 billion of debt and finance leases, a position built largely on $85.68 billion of net IPO proceeds. Backlog stood at $63 billion, of which about $42 billion is expected to convert within a year. Johnsen pointed to the company’s investment-grade standing and several pools of debt capital, arguing that short paybacks will let new capacity begin funding itself in the first half of 2027. Investors annualizing earnings should note that net income exceeded operating income by $1.6 billion. Interest income of $873 million, other income of $1.03 billion, $561 million of it from related parties, and a $390 million tax benefit more than offset $675 million of interest expense. None of those items is a dependable engine.

Market Verdict and the Tesla Question

The shares closed Tuesday’s regular session at $147.79, about 9% above the $135 IPO price but far below the $225.64 high touched in the days after the June listing. At that price, the 13.58 billion Class A and Class B shares outstanding at quarter end imply an equity value of about $2.0 trillion. The stock rose as much as 8% in extended trading after the release. The contrast with August is instructive: after the first report, a capex figure well ahead of models sent the stock down about 14%. This time a larger spending plan arrived alongside revenue guidance that gives investors a visible return path. That verdict now faces a supply test, with roughly 1.3 billion previously locked shares scheduled to become eligible for sale on the second full trading day after results.

Musk also confirmed that SpaceX and Tesla have formed special committees of independent directors, at shareholders’ request, to examine a combination. He called a merger a good idea but said the committees have not agreed terms, that he is excluded from their deliberations as a conflicted party, and that a Tesla vote would need a majority of all outstanding shares, which he called a high hurdle. The results filing itself is silent on the subject, and Tesla reports after the close today. The quarter establishes that SpaceX can monetize compute faster than most skeptics allowed. What it has not yet shown is that returns hold once this year’s spending reaches the depreciation line and the compute market finds its equilibrium. The fourth-quarter capex print, next month’s attempt to catch both Starship stages and delivery against the first-quarter revenue range will supply the next evidence.
