Nvidia’s grip on the artificial intelligence supply chain tightened on multiple fronts this week, as the chipmaker rolled out a next-generation AI model with OpenAI while simultaneously anchoring a major sovereign infrastructure push in the United Kingdom.
The launch of GPT-5.5 for enterprise use on Friday marks a technical leap forward for autonomous AI systems. Powered by Nvidia’s GB200-NVL72 architecture, the new model tackles the industry’s most persistent bottleneck: energy consumption. Nvidia claims a 35-fold reduction in cost per million tokens compared with the previous generation, alongside a dramatic increase in token output per megawatt of power consumed.
The technology is already being stress-tested internally. More than 10,000 Nvidia employees are using the GPT-5.5-powered Codex application, with internal reports showing software development cycles collapsing from days to hours for bug fixes. The shift toward so-called agentic AI systems is reshaping how the company itself builds software.
A Billion-Dollar Infrastructure Bet
OpenAI has locked in a decade-long infrastructure commitment alongside the model rollout, securing more than ten gigawatts of Nvidia-optimised computing power for future world-model development. The first milestone is already complete: a cluster of 100,000 graphics processors has been brought online, marking the operational transition from Blackwell Ultra systems to the new GB200 environment.
Across the Atlantic, Nvidia’s hardware is also powering a very different kind of expansion. BT Group has partnered with Nscale, an Nvidia-backed cloud provider, to build sovereign AI services on British soil. The deal calls for 14 megawatts of capacity spread across three existing BT network sites, with Nscale supplying GPU cloud services and BT handling network connectivity and power.
Nscale is investing roughly $2.5 billion into the UK market over three years, including a 50-megawatt campus in Loughton, Essex. That project has been delayed from late 2026 to the second quarter of 2027 to accommodate installation of the latest Vera Rubin 200 technology. For its clusters, Nscale has secured around 200,000 units of the Blackwell-generation GB300.
Should investors sell immediately? Or is it worth buying Nvidia?
Market Momentum Meets Technical Caution
Nvidia’s shares have been riding a powerful wave. The stock trades at €171.30 in recent sessions, roughly 11% above its 30-day moving average and more than 9% above its 200-day average. Over the past twelve months, the gain exceeds 83%.
The broader semiconductor ecosystem is providing tailwinds. TSMC reported a 58% profit surge in the first quarter, driven by sustained demand for AI hardware. ASML raised its 2026 revenue outlook to between €36 billion and €40 billion.
Yet beneath the surface, some chart watchers are sounding notes of caution. Analysts point to a head-and-shoulders pattern forming on the two-day chart since Nvidia’s February quarterly results. Weak money-flow indicators suggest that recent recovery attempts lack the broad institutional support that powered earlier rallies.
The Sovereign AI Playbook
The BT-Nscale agreement reflects a broader geopolitical shift: governments and corporations increasingly want to control their AI infrastructure rather than outsource it to foreign providers. Similar projects are cropping up across Europe, including the SUSE AI Factory in Prague, which launched on April 21 as a turnkey open-source platform running on Nvidia hardware.
Nvidia sees the sovereign opportunity as enormous. The company estimates the revenue potential of its Blackwell and Vera Rubin platforms at $1 trillion by 2027. For the first quarter of fiscal 2027, it is targeting roughly $78 billion in revenue — a figure that has already surpassed earlier market expectations.
Meanwhile, the next hardware cycle is already in motion. Nvidia is sampling its Vera Rubin architecture, with broad availability expected in the second half of 2026. The company plans to defend its 75% gross margin by shifting to a more complex chiplet counting methodology, cementing its position as the dominant supplier to the world’s AI factories.
