xAI

Elon Musk's xAI raised $6 billion in 2024 at a $24 billion valuation and built the Colossus supercluster in Memphis — 100,000 Nvidia H100 GPUs — in just 122 days, a world record for data center construction speed. Grok 2's integration into X Premium and its first-place ranking on multiple benchmarks demonstrated xAI's capacity to challenge OpenAI from a standing start.
