Nebius Group (NASDAQ: NBIS) posted second-quarter 2026 revenue of US$582.3 million, with its AI cloud division delivering substantial year-on-year growth driven by landmark contract wins.

The company secured four AI infrastructure contracts each exceeding US$1 billion in total value, signaling that enterprise demand for large-scale AI compute capacity remains exceptionally strong.

Nebius also raised its contracted power target to 5 gigawatts, reflecting the scale of infrastructure commitments required to service its growing client base.

The company’s deepening relationship with NVIDIA (NASDAQ: NVDA) continues to position it as a preferred partner for high-density GPU infrastructure deployments across major markets.

Nebius expanded its UK footprint by adding new data center capacity at Vantage’s CWL1 campus in South Wales, accelerating its presence in a region seen as a strategic AI growth zone.

The Wales expansion aligns with UK-focused policy goals around domestic AI infrastructure, while also helping Nebius bring additional high-density capacity online to serve its multi-billion-dollar contract backlog.

The Simply Wall St Community has posted 17 fair value estimates on Nebius ranging from approximately US$35 to over US$400 per share, illustrating sharply divergent views on the company’s growth trajectory.

That wide valuation spread reflects how differently investors are weighing Nebius’s growth potential against its execution risks, heavy capital requirements, and relatively new board structure.

The stock’s strong 12-month run and rich book multiple have drawn short seller scrutiny, keeping capital allocation and delivery on contracted commitments as the most pressing near-term risks for investors.

To own Nebius today, investors must believe its AI cloud platform can convert large contracted power commitments into profitable, long-lived customer relationships despite intense capital needs and sharp share-price swings.

The Wales deal at Vantage’s CWL1 campus adds further upside opportunity, but also raises the bar on what the company must deliver to justify its current market valuation.

Nebius’s rapid build-out of AI infrastructure capacity across multiple geographies gives it meaningful scale advantages, though that same expansion also amplifies the execution and capital-intensity risks that investors must carefully weigh.
