xAI MACROHARDRR data center (Southaven)

Operational

United States · 1 project · Last reported

Summary

Third xAI data center in the Memphis area, made by retrofitting a warehouse of roughly 800,000 square feet that xAI bought in late 2025 in Southaven, Mississippi, just south of Colossus 2 across the state line. Mississippi's governor announced it in January 2026 as an investment of more than $20 billion, the largest economic development project in state history, supported by a state sales and use tax exemption and local fee-in-lieu agreements. Musk said it would lift Colossus training compute to about 2 GW, and a July 2026 report relaying his comments said it holds 220,000 NVIDIA GB300 GPUs.

Status is inferred from a July 2026 WMC report that calls Macro-harder an existing site equipped with 220,000 GB300 GPUs, relaying Elon Musk; no source reviewed confirms when operations began. Converge Digest labels the building 'Colossus 2 (MACROHARDRR)', and analyst estimates for Colossus 2 (xai-colossus-2-memphis) may include it; no Colossus 2 figure is repeated here. The 2 GW figure in the announcements refers to xAI's combined Colossus compute, not this building alone.
