Two years in, and Nscale is already sprinting toward the public markets. The British AI infrastructure company could list as soon as later this month, according to Bloomberg, but first it’s trying to stack another $3.5 billion in financing. The structure is telling: $1.5 billion in convertible notes to a group of investors, plus an additional $2 billion from Nvidia. That’s the same Nvidia that participated in Nscale’s Series B back in March — a $1.1 billion round led by Aker, which Nscale proudly called “the largest Series B in European history.”

What’s driving the urgency? Compute has become the hard currency of the AI boom, and Nscale just landed a monster customer. The company recently signed a deal with Anthropic worth roughly $45 billion. That number has been doing heavy lifting in investor pitches — reports earlier this week indicated Nscale was telling potential backers it now has approximately $103 billion in revenue tied to the deal. But here’s the catch: that’s not money in the bank. The Information clarified the figure reflects projected revenue from signed customer leases, not current sales. It’s a forward-looking number dressed up as a headline.

The gap between projected and realized revenue is where this gets interesting. Data center and compute providers routinely sign long-term leases that look spectacular on paper but take years to convert into actual cash flow. Nscale’s ability to deliver on those leases — power, cooling, GPUs, uptime — is the real test. Anthropic’s commitment suggests confidence, but the infrastructure still has to be built and operated. That’s likely why Nvidia’s involvement matters beyond the check: access to GPUs remains the industry’s biggest bottleneck, and a direct financing relationship with Nvidia could help Nscale secure supply that competitors can’t.

Nscale’s trajectory mirrors the broader AI infrastructure gold rush. In December 2024 the company raised a modest $155 million Series A. Three months later, $1.1 billion. Now potentially $3.5 billion more, with an IPO weeks away. That’s a pace that would have seemed absurd two years ago. Whether the public markets reward that velocity — or punish the gap between signed leases and actual revenue — is about to be tested in real time. TechCrunch reached out to both Nscale and Nvidia for comment; neither has responded publicly.
