Elon Musk’s xAI has bought another building in Memphis, Tennessee, for a planned data center, potentially bringing the company’s compute capacity up to “almost 2GW.”

On December 30, 2025, the tech entrepreneur posted on X, saying: “xAI has bought a third building called MACROHARDRR.”

Musk recently said xAI is working on a purely AI software company called Macrohard. He said Microsoft pun was tongue-in-cheek, but the project was "very real."

The Information reported that the data center, now only a warehouse, will be located somewhere near xAI’s natural gas power plant in Memphis, Tennessee.

When completed, this will be the company’s third data center after Colossus and Colossus 2, the former of which attracted controversy for the unauthorized deployment of 26 gas turbines.

Both facilities are also located in the general vicinity of Memphis.

xAI is best known for developing Grok, its own AI model.

In November of last year, xAI partnered with Saudi Arabia’s Humain to develop a 500MW data center in the Middle Eastern country.
