The short answer
A share of SpaceX is mostly a share of Starlink, a satellite broadband business with 12.0 million subscribers that produced more than half of the company's revenue and was its only segment with operating income in the latest reported quarter. Attached to it are an AI business (the Grok models, the X platform and AI infrastructure), which brought in a third of revenue and lost money; the world's busiest launch business, which mostly launches Starlink; and Starship, a rocket that does not yet earn money and absorbs a great deal of it.
The market values that combination in the trillions of dollars (live figure above) against revenue that annualises to a few tens of billions. That gap is the whole conversation about this stock: the price is a bet on the businesses SpaceX is expected to have, not the ones it has. Whether that bet is a good one depends on judgements about Starship, Starlink's growth ceiling and capital spending that this page lays out but does not make for you.
What a share is a claim on
Starlink. Consumer, business, aviation, maritime and government broadband, plus direct-to-phone service, delivered from more than 10,200 satellites (SpaceX, August 2026). It is a subscription business with the economics of a telecom and the capital costs of a space programme, and unlike Amazon's Leo constellation, which belongs to Amazon rather than Blue Origin, Starlink is inside SpaceX: SPCX is the only way to own it.
Launch. Falcon 9 and Falcon Heavy fly commercial satellites, NASA cargo and crew, national-security payloads and (most of the manifest) Starlink batches; SpaceX launched 165 Falcon 9 rockets in 2025, its prospectus says. External launch revenue, reported in the Space segment, is the older, smaller business; its strategic value is that it makes Starlink deployment cheap and denies rivals the same advantage. Our tracks every flight.
