xAI’s Colossus 2 – First Gigawatt Datacenter In The World, Unique RL Methodology, Capital Raise

SemiAnalysis 10 months ago

xAI is building Colossus 2, a gigawatt-scale datacenter in Memphis with power infrastructure in Mississippi, which it constructed in six months by partnering with Solaris Energy Infrastructure to deploy over 1.1 gigawatts of gas turbine capacity. The company expects to have over 110,000 GB200 NVL72 GPUs operational by Q2 2027, surpassing Meta and Anthropic's clusters and requiring tens of billions in capital funding potentially from Middle Eastern investors. This scale-up positions xAI to maintain its position in frontier AI development and potentially deploy additional datacenters in Saudi Arabia using a capital raise rumored at $40 billion.
