AI data center builder Fluidstack raises $830M at $7.5B valuation

UPDATED 16:52 EDT / JULY 21 2026 INFRA AI data center builder Fluidstack raises $830M at $7.5B valuation by Maria Deutscher Fluidstack Ltd., a startup helping Anthropic PBC build artificial intelligence data centers, has raised $830 million in funding. The company announced the Series A round on Monday. The lead investor was Situational Awareness, an AI-focused fund backed by Stripe Inc.’s founders. The investment values Fluidstack at $7.5 billion. Fluidstack entered the limelight last November when it partnered with Anthropic on a large-scale data center construction project. The companies plan to build $50 billion worth of AI infrastructure in the U.S. over the next few years. At the time of the announcement, Anthropic stated that the first facilities would come online in 2026. Fluidstack’s website doesn’t provide a detailed overview of its offerings. However, the dozens of job postings on the company’s openings page make it possible to piece together a picture of its value proposition. Multi-gigawatt data center construction projects currently take several years to complete. Fluidstack hopes to reduce construction times to six months. It plans to achieve that speedup by assembling customer facilities from prefabricated, or factory-made, modules. Companies usually ship a data center’s building blocks to their construction site and assemble the components on the premises. The workflow involves a significant amount of manual work. Moving some of the work to a factory, the approach that Fluidstack is taking, makes it possible to automate manual tasks with robots. Some of the company’s job postings indicate that it plans to develop customized robot cells. A robot cell comprises a robot arm and auxiliary systems that help it carry out its work. Usually, the automation equipment is placed in an enclosure designed to prevent accidents. Manufacturers often place multiple robot cells next to a conveyor belt and entrust each module with a separate set of tasks. In the case of Fluidstack, those tasks include welding data center parts. The company is also using robots to automate component painting workflows. Fluidstack’s focus is not limited to manufacturing. The company says that it can help customers secure power for their data centers, one of the most challenging tasks involved in AI infrastructure projects. Furthermore, Fluidstack can manage customer facilities after construction is complete. The company is developing custom software to orchestrate clients’ data centers. A job posting for a product designer indicates that Fluidstack is working on a cluster management platform, a program that automatically allocates hardware to AI models. Additionally, the company will offer observability and alerting tools. Fluidstack’s funding announcement comes on the heels of a report that rival Crusoe Inc. is also raising capital. The $3 billion round is expected to value the company at $30 billion. Like Fluidstack, Crusoe assembles AI data centers from prefabricated modules and uses custom software to manage the servers they host.
