Nebius Group disclosed a substantial increase in quarterly capital spending on Thursday, driven by purchases of artificial intelligence processors and stepped-up investments in data center infrastructure as the company races to secure capacity to meet rapidly rising demand. The Amsterdam-based AI cloud firm, which lists Microsoft and Meta among its customers, said it will continue broadening its data center footprint with nine additional locations across the U.S., France, Israel and the UK.
Shares of the company, which surged more than 200% last year, showed volatility in premarket trading and were last up nearly 2%.
Nebius operates as one of the larger so-called neocloud providers that supply specialized hardware and cloud capacity to technology companies. Its principal business centers on providing Nvidia processors and AI cloud infrastructure to enterprise and AI-native customers. Along with its larger competitor CoreWeave, Nebius has been a beneficiary of strong enterprise investment in AI over recent years.
In a letter to shareholders, Nebius CEO Arkady Volozh said: "Demand from enterprises and AI native customers continues to outpace supply, allowing us to sell future capacity well in advance ... We are very focused on investing resources to continue expanding our capabilities in 2026 both organically and through targeted acquisitions."
Capital expenditures ballooned to about $2.1 billion in the December quarter, compared with $416 million in the year-ago period. Those investments have enabled Nebius to lock in more than 2 gigawatts (GW) of contracted power, ahead of its prior projections. The company now expects to have more than 3 GW of contracted power by year-end, an increase from its earlier outlook of over 2.5 GW.
For the fourth quarter, Nebius reported revenue of $227.7 million, more than six times the prior-year quarter, but below the $246.1 million analysts had estimated, according to data compiled by LSEG. Net loss widened to $249.6 million from $133.2 million a year earlier.
Looking farther ahead, Nebius said it expects to finish 2026 with an annualized revenue run-rate between $7 billion and $9 billion, up from $1.25 billion at the end of 2025.
Investors and corporate customers have been willing to commit in advance as demand outstrips current supply, supporting the company s decision to accelerate capacity deployments. Management emphasized a continued focus on growth financed through high levels of investment and potential targeted acquisitions to support the 2026 expansion plan.
Separately, a financial services product note included with the filing highlighted the value of institutional-grade data and AI-powered insights for identifying potential investment opportunities, while noting such tools cannot guarantee outcomes.
As Nebius pushes to expand its hardware footprint and contracted power, the company remains under market scrutiny for how its sizeable capital outlays translate into sustainable revenue growth and profitability over the coming quarters.
