They're successfully launching rockets since 2008 (when they successfully launched small Falcon 1), and started earning big money with Falcon 9 that's flying since 2010. Their biggest customer is NASA, as SpaceX has done over a half of American resupply flights to the ISS (that started in 2012), flying Falcon 9 with their Dragon spacecraft - and these are big contracts, it was $1.6B for 12 flights at the start. Falcon 9 has been sending payloads for many commercial customers since 2013. Since 2020 they're the only American company able to send astronauts to space (at >$200M per flight). Boeing was supposed to be the second option that should be ready around the same time as SpaceX, and they were even awarded more money than SpaceX for development of their spacecraft, but they're not ready yet (which means even more money for SpaceX). By the time SpaceX started sending Starlinks to space frequently, they've already done 70+ launches for various customers. Compare that with Blue Origin that was founded BEFORE SpaceX (in 2000), which launched its first orbital rocket just recently, while SpaceX has launched Falcon 9 rocket 400+ times.
