HAWTHORNE, Calif. — SpaceX built its name on reusable rockets and a satellite internet network that spans the planet. In 2026, it is quietly becoming something else entirely: one of the most important artificial-intelligence infrastructure companies in the world.
The transformation accelerated when SpaceX absorbed Elon Musk's xAI under the SpaceXAI banner earlier this year in a roughly $1.25 trillion combination, folding Grok's development directly into the same company that builds Starship and Starlink. The result is a business that now spans launch, connectivity, and frontier AI compute under a single roof — and, increasingly, a single ticker.
A Compute Landlord at Gigawatt Scale
At the center of the effort are SpaceX's Colossus supercomputing clusters in Memphis, Tennessee, which operate at gigawatt scale and rank among the largest coherent AI training systems ever assembled. Rather than reserve all that horsepower for internal Grok training, SpaceX has aggressively leased it out.
The customer list reads like a who's-who of the AI race. Anthropic is reported to pay on the order of $1.25 billion a month for access to more than 220,000 GPUs, while Google is said to lease roughly 110,000 GPUs for around $920 million monthly, with additional deals such as Reflection AI layered on top. Those arrangements alone are projected to throw off tens of billions of dollars in annual revenue — a stream that increasingly rivals SpaceX's traditional launch and Starlink businesses, echoing the demand behind its server order that sent Super Micro sharply higher.
