UK AI infrastructure hyperscaler; raised $2bn Series C in March 2026, Europe's largest-ever venture round.
Nscale raised $2bn in Europe's largest-ever venture round in March 2026, and by 23 April had become the critical delivery vehicle for Britain's AI Growth Zone ambitions after OpenAI paused its own Cobalt Park data-centre build.

Data Centres: Boom and BacklashBackground
Nscale is a British AI infrastructure hyperscaler founded in May 2024 by Josh Payne, operating a vertically integrated stack covering chips, networking and data centres. Its flagship facilities run on hydroelectric power in Glomfjord, Norway, with further campuses under construction near Narvik.
The company holds a reported $14bn contract to supply approximately 200,000 Nvidia GB300 GPUs to Microsoft across sites in the UK, Norway, Portugal and the US, and its March 2026 fundraise brought former UK Deputy Prime Minister Nick Clegg and former Meta chief operating officer Sheryl Sandberg onto its board alongside Susan Decker.
Nscale is the UK technical partner for the Stargate AI Growth Zone build-out. Its infrastructure footprint spans multiple policy areas: UK sovereign compute policy, European tech sovereignty, AI data-centre economics and the concentration of AI capital, and the DSIT Sovereign AI Unit launched in April 2026 was designed in part to grow UK infrastructure companies to comparable strategic weight.
It raised Europe's largest venture round
Nscale closed a $2bn Series c in March 2026 at a $14.6bn valuation, the largest venture round ever raised in Europe, with Aker ASA and 8090 Industries leading alongside Nvidia, Dell, Citadel and Point72.
The round alone supplied roughly 70% of all London venture capital deployed that March, GBP1.5bn of a GBP2.14bn total; strip Nscale out and the remaining 44 deals raised just GBP644m between them, a scale gap that has defined how every subsequent UK funding total gets read against it.
It becomes the critical delivery vehicle
When OpenAI paused its planned Stargate data centre at Cobalt Park, North Tyneside on 23 April 2026, citing an unfavourable regulatory environment and high energy costs, the Blackstone and Nscale components of the same UK AI Growth Zone programme continued unaffected.
Four days later OpenAI put a number on the underlying problem: UK industrial electricity runs more than four times US and Nordic rates, adding roughly $100m a year at comparable scale. With the highest-profile US partner stepping back, Nscale becomes the government's single most important remaining vehicle for delivering UK AI infrastructure ambitions on schedule.
