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

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.
