Nebius Lands $3.5B Citi Financing for AI Infrastructure

Nebius Group, a prominent player in the specialized AI cloud computing sector, has secured a substantial $3.5 billion financing facility from Citigroup. This significant capital infusion is earmarked for the aggressive expansion of its data center infrastructure and the acquisition of critical Graphics Processing Units (GPUs), addressing the escalating demand for artificial intelligence processing power.

The Amsterdam-based firm's strategic move comes at a time when the AI infrastructure market is experiencing unprecedented growth, with companies racing to build out the necessary computing capabilities. Nebius's agreement with Citi provides access to a senior secured facility, enabling the company to accelerate its global build-out plans without immediate pressure for a larger, long-term capital raise. This flexibility is crucial for managing the significant upfront investments required for data center development, including land acquisition, power systems, cooling solutions, and the procurement of high-performance hardware.

This latest financing underscores Nebius's robust commercial traction, backed by over $40 billion in long-term customer commitments. These substantial contracts offer significant revenue visibility and provide a strong foundation for securing additional debt financing. Ophir Nave, Chief Operating Officer at Nebius, highlighted the company's disciplined approach to capital management, stating, "We continue to execute our funding strategy as planned, and are pleased to have secured this financing from a leading global financial institution." He further emphasized Nebius's ongoing ability to strategically access capital to fuel its growth trajectory.

The $3.5 billion facility from Citi follows a series of significant funding activities by Nebius, including a $775 million senior secured debt facility announced earlier and a $5.75 billion convertible notes offering completed in August. These moves reflect the immense capital requirements inherent in building out the specialized infrastructure needed for advanced AI workloads, differentiating such providers from traditional cloud services.

The strategic importance of this financing is amplified by Nvidia's increasing involvement with Nebius. In July, Nvidia disclosed a 9.3% beneficial ownership stake in Nebius, following a prior $2 billion investment earlier in 2026. This deepens the symbiotic relationship between the leading AI chip manufacturer and a cloud infrastructure provider heavily reliant on Nvidia's hardware. Nvidia CEO Jensen Huang has previously acknowledged the substantial financing needs of AI infrastructure companies, noting that independent lenders critically assess these deals.

Nebius, which traces its origins to the Russian technology giant Yandex, has established itself as a key provider of high-performance computing for AI development. The company competes in a dynamic market alongside other specialized providers like CoreWeave, all vying to meet the insatiable demand for GPU capacity. The $3.5 billion Citi facility is a critical step in Nebius's mission to scale its operations and solidify its position as a leading AI infrastructure provider, navigating the complex interplay between securing capital, acquiring hardware, and delivering essential computing power to the AI industry.
