Nebius Group N.V. (NASDAQ: NBIS) surged today after Nvidia unveiled a $2 billion investment in the company to accelerate the buildout of AI cloud and data center infrastructure, sending the stock to $109.18, up $12.75 or 13.22% in intraday trading.
The sharp move made NBIS one of the session’s strongest AI-linked gainers, with the stock significantly outperforming its sector, which was up only around 0.29%. Earlier in the session, market updates tied the move directly to Nvidia’s decision to back Nebius as the Netherlands-based company expands its hyperscale AI cloud platform.
Trading data showed how aggressive the move was. NBIS had a previous close of $96.43, opened at $105.14, and traded in a day’s range of $104.49 to $109.60. Early volume was about 7,145,747 shares, compared with average volume of 12,516,394. Nebius carried an intraday market value of about $27.693 billion, while its 1-year target estimate stood at $147.45. The company’s 52-week range of $18.31 to $141.10 shows just how volatile investor expectations around AI infrastructure names have become.
Nvidia’s $2 billion bet puts Nebius deeper into the AI infrastructure race
The Nvidia investment is not just a capital injection. It is part of a broader strategic partnership designed to help Nebius expand across the full AI stack, from AI factory architecture to production software, inference capabilities, infrastructure deployment and fleet management optimization.
Nebius said the partnership supports a plan to deploy more than 5 gigawatts of capacity by the end of 2030, a figure that immediately caught investor attention because it points to very large-scale ambitions in AI cloud and data center buildout. The agreement also includes the deployment of multiple generations of Nvidia systems across Nebius’s platform, including the NVIDIA Rubin platform, NVIDIA Vera CPUs and NVIDIA BlueField storage systems.
Nebius is already deploying Nvidia infrastructure across its global platform, including multiple gigawatt-scale AI factories in the United States. That gives the story more substance than a simple headline partnership. Investors are looking at a company trying to scale into a more serious AI compute and cloud player at a time when demand for training and inference capacity remains one of the hottest themes in technology markets.
Jensen Huang’s message adds to the momentum behind NBIS stock
Nvidia CEO Jensen Huang framed the deal around the next phase of AI demand, saying artificial intelligence is moving into another inflection point as agentic AI increases the need for compute and speeds up infrastructure investment. That message matters for NBIS because Nebius is positioning itself as an AI cloud platform built for that demand wave, rather than as a conventional cloud operator.
For traders, that narrative was enough to push the stock sharply higher. Yahoo’s market summary also flagged the move as a standout gain tied directly to Nvidia’s announcement, reinforcing that today’s rally was catalyst-driven rather than part of a broad-based advance in communication services or internet infrastructure names.
The strategic angle is also important. Nvidia is not only supplying hardware to Nebius but helping shape the company’s buildout at a time when access to advanced accelerated computing remains a competitive advantage. In the current market, companies with direct exposure to AI infrastructure spending have often drawn stronger investor interest than software names without a clear monetization path.
The valuation debate remains active despite the rally
Even with today’s surge, the stock still sits in a complicated valuation discussion. Nebius showed a trailing PE ratio of 912.08 and EPS (TTM) of 0.12, figures that underline how much of the current story is tied to future scale rather than mature earnings power. The company also has a beta of 1.16, another sign that investors should expect elevated volatility when sentiment swings around AI infrastructure and growth stocks.
That is why the market reaction is being viewed through two lenses. Bulls see Nvidia’s investment as a strong vote of confidence in Nebius’s ability to emerge as an important AI cloud infrastructure provider. Bears are more likely to focus on the capital intensity of large-scale AI factory expansion and whether the growth story can justify the valuation premium now being priced into the stock.
There is also scrutiny around the broader financing structure behind AI infrastructure deals. Reports around the announcement noted criticism that Nvidia has at times faced over so-called circular financing, where it invests in companies that then buy large amounts of its GPUs and related systems. Similar concerns have been raised in relation to Nvidia’s ties with high-profile AI players and cloud providers including OpenAI, CoreWeave and Anthropic.
That does not erase the strategic significance of the Nebius partnership, but it does add another layer to the discussion. Investors are not just buying a stock rising on momentum today. They are also weighing whether AI infrastructure partnerships of this scale represent durable long-term value creation or whether some of the enthusiasm is being amplified by capital flowing within the same ecosystem.
For now, the market is clearly focused on the upside case. A stock that was trading below $97 at the previous close moved above $109 after the news, showing how quickly investor sentiment can shift when a major AI infrastructure catalyst lands. Nebius now sits more firmly in the conversation around AI cloud buildout, hyperscale capacity expansion and the next leg of demand for Nvidia-powered compute.
Whether NBIS can hold these gains will likely depend on execution, deployment pace and the company’s ability to turn strategic backing into sustained commercial growth. But today’s rally made one thing clear: the market is treating Nvidia’s $2 billion investment as a serious signal that Nebius could become a more important name in the expanding AI data center story.
Investors looking for the broader AI infrastructure backdrop can also track Nvidia’s own positioning through its AI platform strategy, which remains central to how the market is valuing partnerships like this one.
