Opposition and litigation at this site

Nothing on record as of September 13, 2026. No lawsuit, organized opposition, or contested hearing over MACROHARDRR (xAI Southaven Data Center III) in Southaven, DeSoto County, Mississippi appears in the sources this registry tracks. That is an absence in our sources rather than a finding that none exists, and local opposition often predates any coverage a national dataset would pick up.

If you live near this site and something is happening that this page does not show, that is worth telling us. Send us the document and it goes in the record with the source attached. For sites where opposition is already established, see every contested site we track.

Notes on the record

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.

Power capacity in megawatts
The utility's large load service agreement, the interconnection request in the grid operator's queue, or the electrical site plan in the permit file.
Cooling method and water use
The water service agreement, any groundwater appropriation permit, and the mechanical narrative in the site plan.
Tax abatements or other public subsidy
The abatement, PILOT, or development agreement approved by the county, city, or development authority, and the state's data center sales tax exemption certificate if one was issued.
Permanent jobs promised
The economic development application or incentive agreement, which usually states a job commitment and a clawback.
