Stsrlink is about the only thing in the company pulling in solid revenue. There's a good analysis on https://newspaceeconomy.ca/2026/05/30/what-is-starlinks-financial-performance
But basically it's a subscription service which they can sell around most of the planet and compete with infrastructure heavy services (as in expensive to replace them). They also have a lot of enterprise customer usecases (like agriculture and construction) as well as cashcow government (army).
Their growth is actually massive compared to last year, and starlink itself is already profitable. Their economy gets better with the investment in the rocket tech. Starship will be able to lift 20x the amount of starlink than falcon 9, apparently also cheaper, while the next gen starlink sats will also be able to serve a lot more customers. That'll drive their operating cost down, while allowing selling more.
(Just to be clear, spacex as a company is still hot garbage because of the bundling of x and xai and also probably the control structure giving musk all the power while not even holding majority stake, the above is just about starlink and the rocket tech.)
