Musk’s xAI buys third building to expand AI compute power
xAI, the artificial intelligence company founded by Elon Musk, has acquired a third building as part of its effort to significantly expand computing capacity, Musk said on Tuesday. The move is aimed at boosting xAI’s training infrastructure to nearly 2 gigawatts of compute power.
The expansion highlights xAI’s ambition to compete more aggressively with leading AI developers such as OpenAI, which develops ChatGPT, and Anthropic, creator of the Claude chatbot. xAI’s main supercomputer cluster, known as Colossus and located in Memphis, Tennessee, has been described by Musk as the largest in the world.
“xAI has bought a third building called MACROHARDRR,” Musk wrote on X, without revealing the site’s exact location. The name appears to be a play on Microsoft, a major investor in OpenAI.
The Information, which reported the development earlier citing property records and a person familiar with the matter, said the new building is intended to support a third large-scale data centre planned outside Memphis.
According to the report, xAI plans to expand Colossus to house at least 1 million graphics processing units (GPUs). The company is expected to begin converting the newly acquired warehouse into a data centre in 2026. Both the planned facility and a separate expansion known as Colossus 2 are located near a natural gas power plant that xAI is building, alongside access to other power sources.
The rapid build-out of AI infrastructure has drawn criticism from environmental groups, who warn that large data centres consume vast amounts of energy and place strain on local power grids.
