What Starlink is, and why 12 million people use it

How it works

Starlink is the connectivity arm of SpaceX, the company founded in 2002 that also builds rockets and now runs an AI division. Instead of bouncing the web off one distant satellite parked over the equator, it uses a constellation of more than 10,000 small satellites flying only a few hundred miles up. Because they are close, the connection is fast: roughly 20 to 50 milliseconds of delay, against around 600 for old-school satellite internet. To a user, it feels less like satellite and more like ordinary broadband - good enough for video calls and online games, the two things a laggy connection ruins first.

The satellites are the clever part. They talk to one another with laser links, handing your data across the sky to whichever satellite can reach a ground station. That is how Starlink reaches Antarctica, a place with no ground stations at all: a polar satellite relays traffic to stations in South America, New Zealand, or Australia.

The user side is a small motorized dish that needs no technician. It finds the satellites on its own. Early testers in late 2020 reported download speeds above 150 megabits per second, far beyond what many rural phone lines could offer. Since then the service has spread to roughly 160 countries and territories.

How fast it grew

The growth has been relentless. Starlink crossed 1 million subscribers at the end of 2022, 3 million by May 2024, 8 million by late 2025, and more than 12 million by mid-2026. In the second quarter of 2026 it earned $4.29 billion, the single largest line in SpaceX's first earnings report. Starlink is not a side project. By revenue, it is the main business. And all of it now sits inside a company that, in June 2026, staged the largest IPO in history.

Who actually uses it

The subscriber list runs far beyond remote cabins. Airlines put it on planes - United, Qatar Airways, and Lufthansa among them. Cruise lines and cargo ships use it at sea. Governments buy a hardened version. After storms and earthquakes, crews use it to bring communications back fast. SpaceX is also pushing Starlink Mobile, a direct-to-cell service meant to connect ordinary phones with no dish at all. In the first earnings report, president Gwynne Shotwell made the ambition plain: 'I anticipate us to be able to acquire quite a few of their customers because I think our service will be better.'

The scale is hard to overstate. Starlink's satellites now make up roughly three-quarters of every maneuverable satellite in orbit, by one count. And SpaceX is nowhere near finished: a second-generation Starlink Mobile constellation, designed to connect phones directly, could be about ten times the size of the current one and is planned to start flying in 2027, with service by the end of 2027. The long-term goal is to make the dish optional.

Strip away the jargon and Starlink is the most cheerful thing SpaceX has ever shipped. It does not go to Mars. It does not set records on the pad. It just lets someone video-call their family from a place that never had a wire, a tower, or a cable company willing to bother. A farm, a fishing boat, a research station at the bottom of the world - same sky, same dish. That is a quiet kind of magic, and it now pays most of the company's bills.
