SpaceX is now half an AI company, and Starlink is paying for it
Super Intelligence passed half of revenue and swung to its first reported operating profit, $431 million, in a quarter that consumed $16.4 billion of segment capex. The AI buildout is being carried by Starlink's subscription cash and a post-IPO balance sheet, while each subscriber pays less than a year ago.

The beat changed what SpaceX is
SpaceX's+6.79% — SpaceX, up 6.79 percent today second earnings report as a public company beat every line that matters, and it moved the company's center of gravity. Revenue was $14.6 billion, up 161%, with net income of $4.4 billion 1. The $0.35 a share earned beat a $0.16 consensus, and the stock added 1.5% in extended trading 2.
More than half of that revenue, $7.6 billion, came from Super Intelligence, the segment renamed from Artificial Intelligence, which swung to its first reported operating profit, $431 million, even after absorbing $1.2 billion of Cursor share compensation 1. Nameplate compute reached 1.7 gigawatts 1. This is the report our October 20 preview set up.
Super Intelligence is now more than half of SpaceX's revenue
- Super Intelligence$7.6B52.1%
- Connectivity$5.2B35.6%
- All other segments$1.8B12.3%
Data
| Slice | Value | Share |

| Connectivity | $5.2B | 35.6% |
| All other segments | $1.8B | 12.3% |
The profit arrived inside a construction site
The same tables price the inflection. SI capex was $16.4 billion in the quarter, and across nine months it ran 3.6 times the segment's own revenue 1. Whole-company capex, $19.6 billion, was more than twice the quarter's $8.8 billion of adjusted EBITDA 1.
What converts that spend into sales is specific: newly activated cloud services agreements, Cursor's$30B — Cursor, private, latest valuation $30B $608 million of revenue since the August 14 close, and Grok adoption among enterprise customers and consumers 1. The Google and Anthropic$350B — Anthropic, private, latest valuation $350B cloud deals were set to start ramping late in the quarter or in October 3. Grok Bot, the always-on agentic system, is the application layer the compute is being bought for 1.
SI's first profitable quarter still spent more than twice its revenue

Starlink is the printer, and each subscriber pays less
Connectivity, the Starlink segment, is the printer: the subscription business whose cash funds the AI build, the furnace. Its operating income reached $2.4 billion, up 99%, on revenue of $5.2 billion 1.
It earned that on 13.6 million consumer subscribers, nearly double a year ago, each paying $69 a month against $83 1. The base grows while the price per subscriber falls. Add $85.7 billion of net IPO proceeds and tens of billions in fresh debt 1, and a subscription franchise plus a post-IPO balance sheet are funding a buildout that does not yet fund itself.
What the beat leaves unpriced
The 800 MHz spectrum agreement signed on October 8, a nationwide low-band portfolio of up to 14 megahertz paired, carries no price in the release and is expected to close in the first half of 2027 1. Reporting put the deal near $8 billion in cash, for airwaves T-Mobile swapped to Grain Management in August, and it knocked 13.2% off T-Mobile+0.59% — T-Mobile, up 0.59 percent as of its last quote the day it surfaced 45. We weighed that price on October 15.
The bears' case, and the metric that answers it
The soft spots the beat does not touch are the ones bears had already named: Starlink's falling ARPU and the capital consumption of the AI build 6. Those concerns had held the stock 7.7% below its June IPO price into the print 7. CFO Bret Johnsen's answer is what the release calls building "the infrastructure of the future with discipline" 1.
The deciding number next quarter is revenue per gigawatt, the metric analysts flagged going in 3. If the compute added beyond these 1.7 gigawatts 1 earns more revenue per gigawatt than the first tranche did, Starlink can stop carrying the buildout.
