SpaceX S-1 Shows Starlink Leads Revenue, Starship Still Costly
SpaceX's S-1 filing suggests that Starlink is the main source of company revenue, while Starship development is still expensive and not yet fully reusable. Most of SpaceX's money is going into satellites rather than rockets, and Starlink brought in about three-quarters of the company's income in 2025. Partial reuse of Starship might still help lower satellite launch costs, but there are still many uncertainties, like proving Starship can be reused reliably and quickly. SpaceX's future profits may depend on how fast Starship becomes less costly to operate and how well Starlink keeps growing.
