SemiAnalysis: SpaceX raises 2027 AI compute target to about 13GW
Understand this story
SemiAnalysis says SpaceX has raised its 2027 data center capacity target from 10GW to about 13GW, and on that basis judges that SpaceX will become the world's largest AI cloud service provider. According to SemiAnalysis, SpaceX's combined construction scale across multiple new and old sites has already reached 3.6GW, with more than 9GW of feasible capacity additionally identified. All the above figures come from SemiAnalysis estimates, not data published by SpaceX.

- SemiAnalysisElon Is Doing It Again: SpaceX Will Be The World’s Biggest AI Cloud
SemiAnalysis reports that SpaceX now has 3.6GW of datacenter capacity under construction across multiple sites and has raised its 2027 estimate to roughly 13GW, which would exceed all of Google's datacenter capacity built from 1999 to 2026. The report says SpaceX may be the world's fastest datacenter builder, citing Colossus 2 build times of 91 days for 210MW and a planned ~4-month greenfield build at a Mississippi site, plus a datacenter likely planned at the TeraFab chip fab site in Texas. It also tracks over 8GW of likely behind-the-meter power, a ~6GWh BESS deployment at Colossus 2, and a 500kV substation connecting Macrohard (700MW) and MiniHard (450MW) to TVA service.
