Fluidstack

Builds and operates purpose-built AI data centers at gigawatt scale — the first known operator of Google TPU sites outside Google, and Anthropic's build partner.
Fluidstack builds and operates purpose-built AI data centers, renting space and operations to AI labs rather than buying and reselling chips the way CoreWeave and Nebius do — a model it claims lets it stand up a site in three months against a year or more for Google, Amazon or Meta. Founded in 2017 by Oxford students Gary Wu and Jamie Cox (joined in 2020 by César Maklary, previously a Formula One aerodynamicist), it started by renting idle gaming GPUs to AI researchers, shifted to whole-cluster rental during the pandemic, and moved into data center construction after ChatGPT. It has become the proving ground for Google's push to sell TPUs against Nvidia: it appears to be the first publicly known operator of TPU data centers outside Google, and in November 2025 Anthropic said it would invest $50 billion in new data centers built by Fluidstack for a rollout of up to 1 million TPUs. It has locked up power from struggling bitcoin miners TeraWulf, Cipher Mining and Hut 8 in decade-long, Google-backstopped contracts totalling just under a gigawatt, leased over 1 million square feet outside Glendale, Arizona, and is building a site west of Abilene, Texas. Other customers include Meta, Jane Street, Black Forest Labs, Poolside and Mistral. It walked away from an $11.5B French data center announced at Macron's 2025 AI Action Summit, citing faster access to power in the US, and relocated its headquarters from London to New York in December 2025. Beyond equity it has raised over $15 billion of project debt with partners including Coatue's data center arm.
