This is captive capacity. The operator does not sell GPU-hours, so no price on GPUQuant refers to it.
No provider names an area that GPUQuant has recorded as containing this building.
A power or accelerator figure appears above only where an operator or a filing states it.

Memphis is home to Colossus, a state-of-the-art supercomputer that is also the computing power behind Grok – SpaceXAI’s revolutionary AI companion. By 2026, SpaceXAI plans to equip this facility with 1 million GPUs (special computer chips) to enhance the speed and intelligence of our AI systems.
SpaceXAI transformed a vacant 1-million-square-foot factory in Southwest Memphis into a cutting-edge technology hub.
Utilizing existing infrastructure in the former Electrolux facility, already zoned for our use.
We have provided tens of millions of dollars in local tax revenue since we arrived in Memphis in March 2024.
At our Electrolux site we have on-site energy storage (over 240 batteries) and 15 permitted natural gas generators with best-in-class emissions control technologies that will serve as back-up power in emergencies, or when the local grid is strained during times of deep cold or heat.
Built in 122 days — outpacing every estimate — Colossus was the most powerful AI training system yet. Then we doubled it in 92 days to 200k GPUs. This is just the beginning.

xAI’s Gigafactory of Compute – the World’s largest supercomputer – would be located in Memphis, Tennessee.
In a landmark announcement at the Greater Memphis Chamber Annual Chairman’s Luncheon, xAI revealed plans for an expansion of its “Colossus” supercomputer facility.
"AIRStatus":"Operating"
"AIRName":"COLOSSUS DATA CENTER"
In 2024, the world’s largest supercomputer, Colossus, became operational on President’s Island in Memphis, Tennessee.
Beginning in early June 2024, CTC began installing and, thereafter, operating numerous gas turbines at its facility in Southwest Memphis without obtaining any air permit or other written approval from the Health Department.
