Starlink Surpasses 10 Million Users as SpaceX Scales Gigawatt AI and Readies Orbital Compute

Starlink orbital AI compute is no longer a thought experiment: SpaceX has stood up gigawatt-scale AI training infrastructure on the ground and is now advancing plans to place portions of that compute in orbit, powered by sunlight and cooled by radiation. The push comes as Starlink's active user base crossed 10.3 million by the end of Q1 2026, more than doubling in the prior year. Its constellation now accounts for roughly three-quarters of every active maneuverable satellite in orbit, with coverage spanning more than 164 countries and territories and serving over three billion people.

Key Takeaways

Starlink reached approximately 10.3 million users by the end of Q1 2026, reflecting more than 100 percent year-over-year growth from roughly 4.4 million users at the end of 2024.

The network now represents about 75 percent of all active maneuverable satellites currently in orbit.

Service is live across more than 164 countries and territories, providing coverage to populations exceeding three billion people.

Adoption is accelerating in aviation with frequent new airline integrations, while enterprises increasingly use Starlink as primary or backup connectivity for operational resilience.

Starshield operates as a dedicated constellation delivering secure capabilities tailored to U.S. government needs.

The first-generation direct-to-device service, activated with 650 satellites and partnerships involving 30 mobile network operators, has already demonstrated coverage for 1.9 billion people and confirmed real demand.

A second-generation direct-to-device system is designed to deliver full 5G performance directly to standard phones, targeting connectivity for the remaining three billion people currently outside reliable networks.

Colossus Two has been deployed as the world's largest coherent supercomputer, incorporating NVIDIA GB300 processors as the first gigawatt-scale training cluster along with the first gigawatt-scale Megapack battery installation and early large-scale use of both GB200 and GB300 hardware.

Orbital AI compute capacity is under active development for deployment within the next couple of years, leveraging solar power generation and radiative cooling in the space environment.

Proven satellite subsystems already in production—including ion propulsion thrusters, inter-satellite laser links, flight computers, and reaction wheels—remove key technical barriers to placing AI workloads in orbit.

Vertical integration across launch, satellites, connectivity, and AI creates a self-reinforcing loop: better infrastructure improves model quality and lowers token costs, which in turn funds further capacity expansion.
