Fluidstack, an AI datacenter startup, is in talks to raise $1 billion at an $18 billion valuation, reportedly led by Jane Street. This would more than double the company's valuation from $7.5 billion in December. Fluidstack builds specialized data centers for AI companies like Anthropic, which signed a $50 billion deal with the startup. The company relocated from the UK to New York and recently exited a French AI project to focus on U.S. opportunities.
