FluidStack AI Datacenter Startup in Talks for $1B Funding at Skyrocketing $18B Valuation After $7.5B Jump

FluidStack, a leading AI datacenter provider, is reportedly in advanced talks to raise $1 billion at an impressive $18 billion valuation.

This potential round comes just months after the company secured around $700 million at a $7.5 billion valuation in December 2025.

FluidStack's Explosive Growth Trajectory

Originally spun out of Oxford University, FluidStack has emerged as a key player in Europe's AI infrastructure scene.

The startup gained massive traction in the U.S. following a landmark deal with Anthropic to build custom data centers in Texas and New York.

Prior to that, FluidStack powered infrastructure for European AI leader Mistral and now serves major clients like Meta, Poolside, and Black Forest Labs.

Strategic Shifts and Investor Interest

In a bold move, the company recently withdrew from a €10 billion French AI project to prioritize U.S. expansion opportunities.

Trading giant Jane Street is in discussions to lead the new round, with previous backer Situational Awareness—an AGI-focused fund—likely co-leading.

Google was previously considering a $100 million investment during February talks, highlighting broad interest from tech giants.

Implications for AI Infrastructure Boom

This valuation surge from $7.5 billion to $18 billion underscores the exploding demand for specialized AI compute resources.

As AI models grow hungrier for power, startups like FluidStack challenge hyperscalers such as AWS and Google Cloud by offering tailored solutions.

Looking ahead, the funding could fuel aggressive data center builds, positioning FluidStack as a cornerstone of the global AI revolution.
