This is a source-attributed discovery row. It can help you find a place and its citations; it is not a DataCenterData finding that the facility is distinct or currently operating.

What the source record says
xAI's third Southaven/DeSoto County site, distinct from the existing dataset records for 'Colossus' (xai-southaven-ms, the data center at the former Electrolux plant) and 'Colossus 2' (xai-colossus-2-power-station-southaven-ms, the power station). MACROHARDRR retrofits an 810,000 sq ft former warehouse at 2400 Stateline Road West. Elon Musk announced the building purchase via X on 2025-12-30; Gov. Tate Reeves' office announced the '>$20 billion' investment and 'hundreds of permanent jobs throughout DeSoto County' on 2026-01-08, citing Mississippi's Data Center Incentive Program (sales/use tax exemptions on computing equipment and software) plus City of Southaven and DeSoto County fee-in-lieu agreements. xAI separately purchased two adjacent parcels (47 and 58 acres) near its power plant at 2875 Stanton Road; that acreage is not clearly attributable to this building's own site, so landAcres is omitted here rather than guessed. Musk's public claim that MACROHARDRR takes combined xAI Memphis-area training compute to '~2GW' describes the whole multi-site cluster, not this building's own capacity, so capacityMw is also omitted. Operational status is per Baxtel (aggregator, retrieved 2026-09-13); not yet independently corroborated by an xAI or Mississippi state press release stating a completion date, though a February 2026 operational target was reported at announcement.
Any MW value is reproduced as source-reported context. Its measurement boundary is not established consistently enough for comparison. Unknown is not zero.

Compute Atlas 1.34.1 with retained prior rows and publication holds. This is a DataCenterData composite, not an unmodified publisher edition. This row uses the captured source from 1.34.1, source as of 2026-10-14T20:40:52.293Z.
That does not mean the row is wrong, and it does not mean no reviewed record exists for the same place. A link is added only when an identifier or source establishes the match.
