Overview
- Gov. Tate Reeves said xAI will build the MACROHARDRR facility in Southaven, calling the $20 billion project the largest private investment in Mississippi history.
- The company expects the site to begin operations in February 2026.
- The Mississippi Development Authority certified the project for its Data Center Initiative, with state waivers on sales, corporate income and franchise taxes and local agreements for substantially reduced property taxes.
- xAI says the Southaven build, part of a Memphis-area cluster near a newly acquired power-plant site and an existing Tennessee facility, will push its training compute to about 2 gigawatts and constitute the world's largest supercomputer.
- Civil-rights and environmental groups have organized to oppose the development over pollution and equity concerns, including a Southaven petition with more than 900 signatures.
