Fluidstack in talks for $1B at $18B valuation
Fluidstack, an AI-focused data-center startup, is reportedly in talks to raise a $1 billion financing round at an $18 billion valuation, potentially led by Jane Street, according to Bloomberg. The potential raise would more than double a previously reported funding effort in December when the company was said to be raising around $700 million at a $7.5 billion valuation. Fluidstack has secured large commercial interest: Anthropic signed a reported $50 billion deal with the company to build custom AI data centers, and Fluidstack counts customers including Meta and Mistral. The startup relocated its headquarters from the U.K. to New York and recently pulled out of a €10 billion AI project in France to focus on U.S. opportunities.
A large potential $1B funding round and a major commercial deal with Anthropic signal rapid expansion of AI-specific data-center infrastructure, which affects capacity and supply dynamics for AI model training and inference.
