Elon Musk's artificial intelligence company xAI has announced a landmark $20 billion investment to build a data centre in Southaven, Mississippi, representing the largest private investment in the state's history according to Governor Tate Reeves.
Project Details and Scale
The data centre, designated as MACROHARDRR, will be constructed in Mississippi's DeSoto County near Memphis, Tennessee. This facility marks xAI's third data centre in the greater Memphis area, contributing to what the company describes as a cluster of facilities.
| Project Parameter: | Details |
|---|---|
| Investment Amount: | $20 billion |
| Location: | Southaven, Mississippi (DeSoto County) |
| Facility Name: | MACROHARDRR |
| Computing Power: | 2 gigawatts |
| Expected Operations Start: | Next month |
xAI CFO Anthony Armstrong stated that the cluster of data centres will house "the world's largest supercomputer" with 2 gigawatts of computing power, positioning the facility as a significant technological infrastructure development.
Environmental Concerns and Community Opposition
The announcement comes amid growing scrutiny over xAI's data centre projects in the Memphis area. The NAACP and the Southern Environmental Law Center have raised concerns regarding air pollution generated by xAI's supercomputer facility, particularly its impact on predominantly Black communities in Memphis.
Local opposition has organized through the Safe and Sound Coalition, a Southaven group that has launched a petition calling for the shutdown of xAI's operations in the area. The petition had received more than 900 signatures as of Thursday afternoon, demonstrating community resistance to the project.
A fact sheet released by the Mississippi governor's office addressed these concerns, stating that environmental responsibility represents a "core commitment" for xAI, though the company did not immediately respond to requests for comment about specific environmental concerns.
Economic Impact and Tax Incentives
Governor Reeves predicted the investment will generate substantial economic benefits for the region, including hundreds of permanent jobs, thousands of indirect subcontracting positions, and increased tax revenue to support public services.
| Economic Benefits: | Details |
|---|---|
| Permanent Jobs: | Hundreds |
| Indirect Jobs: | Thousands (subcontracting) |
| Tax Revenue: | Enhanced public services funding |
| Property Taxes: | Substantially reduced rates |
Under incentives for data centres passed in 2024, Mississippi will waive all sales, corporate income, and franchise taxes on the xAI development. The savings on sales taxes for the computing power purchases alone would likely represent substantial value, though the Mississippi Development Authority did not immediately respond to questions about the total tax revenue the state will forgo.
DeSoto County and the city of Southaven have also agreed to provide substantially reduced property tax rates as part of the incentive package. xAI expects to begin data centre operations in Southaven next month, indicating an accelerated timeline for the project's initial phase.
