Fluidstack In Talks For $1 Billion Raise At $18 Billion Valuation With Jane Street Eyed As Lead

Investor interest reflects a huge Anthropic build contract that pushed the Oxford startup to refocus on U.S. data centers.

Overview

  • Fluidstack is negotiating a $1 billion funding round that would value the AI data center builder at about $18 billion, according to Bloomberg and TechCrunch.
  • The new figure would more than double a December report that it was raising about $700 million at a $7.5 billion valuation, which the company did not announce as closed.
  • Jane Street is being discussed as lead investor, with Situational Awareness in the mix and Morgan Stanley advising, according to reporting.
  • Anthropic confirmed a $50 billion deal for custom facilities in Texas and New York, which underpins demand for Fluidstack’s AI‑focused buildouts.
  • The company has shifted toward the U.S., moving its headquarters to New York and exiting a €10 billion French project to prioritize American sites.
