xAI Colossus 2

A second, physically distinct xAI supercluster in the Memphis area, built at 5420 Tulane Road in the Whitehaven area of Memphis with associated gas turbine power generation across the state line in Southaven, Mississippi, separate from the original Colossus site (xai-colossus-1) at the former Electrolux factory in South Memphis. Mississippi's governor announced an expansion of the site in January 2026 quoting Elon Musk directly that combined Colossus training compute was approaching "~2GW", and Introl's infrastructure industry blog independently reports an initial GB200/GB300 cluster reaching roughly 1 GW for Colossus 2 alone, though the reported GPU count shifts across sources and over time (on the order of 110,000 GPUs at first light in January 2026, reported by other outlets as growing toward 550,000 later in the year) and, while the earliest roughly 110,000 figure is an outside analyst's estimate from cooling capacity, the larger figures rest on Musk's public statements rather than an xAI technical disclosure. Given that spread, no specific GPU count is recorded on this row; the accelerator component row below carries the range with confidence reported and flags it as an estimate. No FLOPS, interconnect vendor or cooling vendor is independently confirmed for this system specifically.
