AI datacenter startup Fluidstack in talks for $1B round at $18B valuation months after hitting $7.5B, says report

AI datacenter startup Fluidstack is in talks to raise $1 billion at an $18 billion valuation, potentially led by Jane Street, after rapid valuation growth from $7.5 billion in December. The fundraising follows a landmark $50 billion deal with Anthropic to build custom data centers in Texas and New York. The company's specialized AI-focused infrastructure model contrasts with hyperscalers like AWS and reflects a strategic shift by leading AI companies toward dedicated, controlled compute.
