What is the claim?

Elon Musk said he was "highly confident" that SpaceX could build 10 GW of data center capacity in 2027 alone. SemiAnalysis analysts calculate that adding this on top of the existing 3 GW would put the company at the same capacity Google built over its entire existence, in just 1.5 years.

What is it based on?

The analysts track construction at the Colossus 1 and Colossus 2 sites using aerial imagery and public information. Colossus 2's power capacity is projected to rise from 0.4 GW in January to 2.4 GW by year-end. Across the sites they monitor, they tally roughly 9 GW of potential capacity.

The power bottleneck

The facilities house 89 turbines capable of about 2.5 GW and 1,377 Tesla Megapack batteries. Emissions rules will eventually limit the site to roughly 1.24 GW from its own turbines; with 1.2 GW coming from the grid, a shortfall of about 300 MW is expected to be covered by batteries. SpaceX has an agreement with Mississippi allowing temporary operation of extra turbines, with a phase-out promised by July 2027.

Speed, but also obstacles

The analysts note SpaceX starts builds before deciding how a facility will be powered, and that Tesla appears to manufacture mechanical and electrical equipment in modules. Still, zoning, permits, grid connections and public opposition can delay capacity from actually coming online. As Microsoft CEO Satya Nadella put it, having chips in inventory that you cannot plug in is a problem in itself.
