Tesla and SpaceX CEO Elon Musk’s xAI company has purchased a third building near its existing Memphis sites in the US, that will bring its artificial intelligence (AI) computing capacity to almost 2 gigawatts (GW).
Elon Musk has already built one data centre in Memphis, known as Colossus, and is constructing a second centre nearby dubbed Colossus 2, according to multiple reports.
The newly acquired building is in Southaven, Mississippi, and adjoins the Colossus 2 facility, according to reports citing people familiar with the matter.
“xAI has bought a third building called Macrohardrr,” Musk posted on social media platform X, saying it will “take @xAI training compute to almost 2GW.”
A gigawatt is enough to provide electricity for about 7,50,000 US homes. Musk has publicly discussed plans to build the world’s largest data centre for AI training and previously said Colossus 2 will eventually have 5,50,000 chips from Nvidia, costing tens of billions of dollars.
Moreover, Musk’s xAI Holdings is reportedly in talks to raise new funding at around $230 billion valuation. Musk owns a 53 per cent stake in xAI Holdings, worth $60 billion.
Musk took a dig at Wikipedia in October, claiming Grokipedia, developed by xAI, will surpass the popular online encyclopedia “by several orders of magnitude in breadth, depth and accuracy.”
Grokipedia is an AI-powered encyclopedia that aims to challenge what Musk calls a “woke” and biased Wikipedia.
