Fluidstack Eyes $1B Round at $18B Valuation

Fluidstack, a startup focused on building specialized data centers for AI companies, is reportedly in discussions to raise a significant $1 billion funding round. This round could potentially value the company at $18 billion, a substantial increase from its previously reported valuation.

Earlier this year, in December 2025, Fluidstack was rumored to be raising approximately $700 million at a $7.5 billion valuation. The company has recently attracted major attention due to a $50 billion deal with Anthropic, announced in November 2025, to construct bespoke data centers in Texas and New York. This partnership underscores Fluidstack's strategic importance to AI firms requiring dedicated infrastructure.

Unlike general cloud providers, Fluidstack's infrastructure is custom-designed for the unique demands of artificial intelligence. This specialization has made it a key player, with other notable customers including Meta and Mistral. The company's relocation of its headquarters from the UK to New York and its withdrawal from a major French AI project further emphasize its focus on U.S. market opportunities.
