Starlink

Starlink is SpaceX's low-Earth-orbit broadband network, first deployed in May 2019. It is by far the largest satellite constellation in history — over 10,000 satellites operating — and crossed 10 million subscribers in early 2026, adding its most recent million in just 53 days.

Starlink brings real internet to rural and remote places terrestrial networks never reached, and has provided critical connectivity in disasters and conflict zones, most prominently Ukraine from 2022. It serves aviation, maritime and enterprise customers, and through "Direct to Cell" with T-Mobile and other carriers it now connects ordinary phones from space to eliminate dead zones.

Starlink is also a financial engine: it generated an estimated ~$11.4B in revenue in 2025 at a high margin, underpinning SpaceX's valuation independent of any single product.
