Fluidstack, an AI data center startup, is reportedly in advanced talks to raise $1 billion at an $18 billion valuation, just months after being valued at $7.5 billion, according to sources familiar with the matter. The funding discussions follow Fluidstack’s $50 billion agreement to build data centers for AI firm Anthropic, signaling intense investor appetite for AI infrastructure companies.
The potential funding round would position Fluidstack among the most valuable private AI infrastructure companies globally. Analysts attribute the skyrocketing valuation to unprecedented demand for GPU clusters powering large language models like those developed by Anthropic. “The AI data center space is seeing hockey-stick growth curves we haven’t witnessed since the early cloud computing days,” said a Tier 1 bank analyst speaking anonymously due to client relationships.
Fluidstack’s reported valuation jump comes amid fierce competition for AI compute resources. Industry sources note the company has secured preferential access to Nvidia’s latest GPUs, a critical advantage given global chip shortages. However, some investors express caution about the sector’s overheated valuations. “We’re seeing multiple expansion disconnected from traditional metrics,” noted a venture capitalist at a Tier 2 firm.
If completed, the funding would accelerate Fluidstack’s plans to build 12 new hyperscale data centers across North America and Asia by 2027. The company’s technology focuses on liquid-cooled, modular data centers optimized for AI workloads.
