Details

AI data center startup Fluidstack is in talks to raise $1 billion led by Jane Street, which would push its valuation up to $18 billion.

If completed, this would mark a sharp jump in valuation within just a few months. Back in December, reports emerged that the company was pursuing a $700 million raise at a valuation of about $750 million, and in February, Google was reported to be considering putting $100 million into that round.

Fluidstack has raised its profile through a major deal with Anthropic. Anthropic signed a $50 billion data center deal with the startup, after which Fluidstack moved its headquarters from the UK to New York. The company also dropped out of France's €10 billion AI project, and currently counts Meta, Poolside, Black Forest Labs, and Mistral among its customers as well.
