## Summary

SemiAnalysis says SpaceX now targets about 13GW of datacenter capacity in 2027, with 3.6GW already under construction across multiple sites. The report credits faster build times, including Colossus 2 retrofits and new greenfield sites, and says SpaceX's behind-the-meter power plans and large battery storage deployments make the schedule plausible. Part of the analysis is paywalled.

## Why it matters

The report traces SpaceX's datacenter build timelines, power sourcing, and site-level evidence, giving readers a concrete basis for judging its claimed 13GW capacity target.
