xAI

Elon Musk's xAI raised $6 billion in a Series B round in 2024 at a $24 billion valuation, funding the construction of its Memphis Colossus supercluster of 100,000 Nvidia H100 GPUs — the world's largest AI training facility. Grok's integration into X Premium positioned xAI as a direct competitor to OpenAI in both consumer and developer markets.
