Bloomberg reported on April 14 that Fluidstack is in talks to raise about $1 billion at an $18 billion valuation, a potential jump from the $7.5 billion valuation Bloomberg had previously reported for the company late last year. TechCrunch separately summarized the report and said Fluidstack did not respond to its request for comment.

What is reported

The conservative, verified version is that this is still a reported financing discussion, not a closed round. Bloomberg's headline says Jane Street is in talks around the deal, while TechCrunch described Fluidstack as a startup building specialized data center capacity for AI companies rather than a general-purpose cloud vendor.

Fluidstack's own site positions the company around GPU cloud and AI infrastructure, which helps explain why the reported valuation matters. Investors have continued to treat power, compute, and custom capacity as strategic choke points in the AI stack, especially as demand keeps outrunning supply.

Why it matters

If talks on these terms are completed, the raise would rank among the larger recent capital events in AI infrastructure, not just in software. It would also reinforce the market's willingness to back providers that sit underneath model builders and application companies.

For now, the safest takeaway is narrower: Fluidstack is reportedly pursuing a very large round, but the financing has not been formally announced and terms could still change.
