xAI Colossus 2
AI data center in Memphis, Tennessee, operated by xAI (SpaceXAI, part of SpaceX since 2026).
xAI's second Memphis campus on Tulane Road, built as the first gigawatt-scale AI training site. SpaceX's 2026 S-1 describes a next phase of at least 220,000 more GB300 processors and over 400 MW.
Power: what each source says
Epoch AI estimates 946 MW IT / 1,276 MW facility as of 2026-06-15 and projects ~1.5 GW IT (~2 GW facility) by early 2027 after a third building. Musk and press reports cite ~2 GW total; GPU counts reported by Musk (550,000+ GB200/GB300) are unaudited.
Figures labelled Epoch AI are estimates from satellite imagery, permits and filings. Company figures come from the operator, owner or its filings. IT power is what the servers draw; in Epoch AI’s figures for these campuses it runs about 15–35% below total facility power.
Tenants
