Elon Musk’s artificial-intelligence company xAI is expanding. That should be good news for Nvidia, Dell Technologies and Super Micro Computer.
Musk’s xAI has purchased a third building to expand its massive data center complex near Memphis. The Tesla CEO said the acquisition will help boost the company’s AI training capacity to nearly two gigawatts of computing power.
“xAI has bought a third building called MACROHARDRR,” Musk posted to social-media platform X on Tuesday. “Will take @xAI training compute to almost 2GW.”
That building is about to be filled with a lot of AI hardware, with Nvidia, Dell and Super Micro as the most likely vendors.
The Memphis complex, called “Colossus,” already houses over 200,000 Nvidia chips and powers the technology behind the AI chatbot Grok. Eventually the site is set to incorporate a minimum of one million graphics-processing units, according to a statement from the city’s chamber of commerce.
Nvidia shares fell 0.6% on Wednesday.
Meanwhile, Dell and Super Micro have been xAI’s chosen suppliers of servers to house those Nvidia chips. The company has agreed to buy $5 billion worth of Dell servers, according to a Bloomberg report earlier this year. Dell shares down 1.6%.
Super Micro has also been repeatedly identified as a server supplier for the Colossus project. Shares were down 1.3% Wednesday and the stock remains well off its highs reached in early 2024.
