The document that reframes SpaceX is the prospectus the company published in June 2026, and one line of arithmetic does most of the work. Connectivity, the segment led by Starlink, booked $11.387 billion of revenue in 2025 and $4.423 billion of income from operations. The rocket business, grouped in a segment called Space, took in $4.086 billion and finished $657 million in the red. The strategic calculus has flipped: the launch system that once carried the broadband network is now carried by it.
Strategically, the share is what signals the shift. Group revenue was $18.674 billion, so Connectivity supplied 61 percent of total sales, and Space Daily calls it “apparently the first” satellite-broadband operation ever to pass $10 billion in a single year. The hedging is deliberate. No complete register of every satellite operator exists, and accounting periods differ. The nearest comparators underline the point anyway: EchoStar’s broadband and satellite services segment reported $1.456 billion for 2025, Viasat’s whole company managed about $4.5 billion, SES recorded €3.512 billion and Eutelsat €1.244 billion, of which its OneWeb low-orbit arm contributed just €187 million.
The Engine Room
Growth built the position. Connectivity revenue rose 49.8 percent in 2025 from $7.599 billion, having been $3.869 billion in 2023, nearly a tripling across two years on recurring service relationships rather than one-off hardware sales. Operating income more than doubled from $2.006 billion, and the segment’s operating margin ran near 38.8 percent.
The details deserve care, because operating income is not cash. It sits after $6.964 billion of segment costs, leaves interest and tax aside, and a network thick with assets keeps spending on spacecraft, launches, terminals and ground systems. The prospectus separately lists $7.168 billion of adjusted segment EBITDA. The rocket segment’s $657 million loss, meanwhile, is an operating figure too: Space still produced positive adjusted EBITDA of $653 million, and its result carried $3.004 billion of research and development spending, up 63.7 percent, which SpaceX tied mainly to accelerated Starship work.
One System Financing the Next
The label “Bankrolling” is an inference, as the column itself concedes, but a grounded one. Connectivity’s operating profit came in roughly $1.419 billion above the whole research budget of the Starship-heavy Space segment, and the prospectus says cash from operations funds research including Starship and next-generation satellites. No ledger traces a household subscription to a Raptor engine; the loop is real all the same.
The two sides are stitched together by flight rate. SpaceX flew 165 Falcon missions in 2025, and only 43 of them served outside customers; 122 were internal, most expanding or replenishing the constellation, which has crossed 11,000 satellites in orbit. Falcon gives Starlink cheap, frequent orbit access, and Starlink gives Falcon a customer able to sustain a cadence no external market would.
Two caveats temper the headline. Subscriber count grew 99.9 percent in 2025, but revenue per subscriber slid 11.2 percent on average, so growth is coming from widening, not from pricing power. And the group’s 2025 accounts were recast to include xAI, acquired on 2 February 2026: the AI segment adds $3.201 billion of revenue and a $6.355 billion operating loss, which is why the combined company booked a $2.589 billion operating loss even with Starlink in profit. Count only Space and Connectivity, and the broadband arm’s share of their revenue is about 73.6 percent. Either way, the broader stakes are the same: one recurring-revenue business is now paying for the next rocket.
