SpaceX’s 2027 AI datacenter estimate rises to about 13GW
SemiAnalysis reports that SpaceX has about 3.6GW of data-center capacity under construction across multiple sites and has identified more than 9GW of potential capacity at Colossus, Starbase and other tracked locations. The firm says SpaceX’s estimate for 2027 has risen to approximately 13GW, while Elon Musk has claimed high confidence that the company could build 10GW during that year. These figures are estimates or targets rather than confirmed operating capacity, and power availability, grid connections, permitting, emissions rules and hardware supply could constrain the rollout.
SpaceX’s reported construction progress would put it on a path to deploy AI-compute capacity on the scale of Google’s entire 1999–2026 buildout within roughly 18 months, according to SemiAnalysis.
We wrote at length about how SpaceX’s plans for 10GW in 2027 was feasible, paving the way for 300b+ ARR. We received a lot of pushback from folks calling it impossible. Now, just two months later, we’re already seeing 3.6GW under construction across multiple sites, both existing and new. SpaceX has even revised its estimate up to ~13GW in 2027. This would be the largest amount of datacenter capacity ever built by any one company in that timeframe, roughly equivalent to all of Google’s datacenter capacity from 1999-2026 in just 1.5 years. We think it’s possible and have already identified >9GW of capacity.
We’ve since written multiple update notes to our Datacenter Industry Model subscribers showing off all the sites that can make this possible. We now believe that SpaceX may be the fastest datacenter builder in the world, even more so than Chinese peers. Watch how Colossus 2 adds nearly two Stargate Abilenes (2GW) in just under one year!
