Summary
- Nebius has arranged $3.5 billion of senior secured financing with Citi.
- The 364-day facility initially carries interest at Term SOFR plus 2.75 percentage points.
- The financing supports global expansion and is not allocated exclusively to Europe.
Nebius has arranged a $3.5 billion senior secured financing facility with Citi to support data centre development and GPU procurement, adding short-term borrowing capacity to its international AI infrastructure expansion programme.
The Amsterdam-based company disclosed the arrangement on 22 October. The facility has a maturity of 364 days and initially carries an interest rate of Term SOFR plus 2.75 percentage points, with the contractual margin capable of increasing to a maximum of 3.50 percentage points.
Nebius said the new financing would provide flexibility over the timing and structure of additional funding as it continues to develop infrastructure for AI computing customers.
The facility is part of a broader financing strategy that includes customer prepayments, operating cash flow, convertible debt and other borrowing arrangements. The company has reported more than $40 billion of long-term commercial contracts with major customers, including Microsoft and Meta.
Those contracts provide visibility into future demand, but their total value is not equivalent to cash immediately available for construction. Customer payments, project expenditure and revenue recognition can occur at different stages of a multiyear infrastructure programme.
Data centre construction creates substantial cash requirements before new capacity enters service. Developers must fund building work, power distribution, cooling systems, connectivity, and the equipment needed to host customer workloads.
AI infrastructure introduces an additional timing challenge because large GPU purchases must be coordinated with the availability of operating facilities. Delays to power or cooling infrastructure can affect the date on which expensive computing equipment becomes productive, while equipment delivery schedules can also influence commissioning plans.
The Citi arrangement provides another source of funding during that process. Its short maturity means it should not be treated as permanent financing for the long economic life of the facilities being developed.
The borrowing rate is linked to Term SOFR, meaning interest costs will depend on the applicable benchmark and the agreed contractual margin. The secured structure also distinguishes the facility from unsecured borrowing and other forms of capital available to Nebius.
According to the company, the arrangement supports its global capacity programme. It has not allocated the full $3.5 billion to any named European facility, and the announcement should not be interpreted as a financing commitment exclusively for projects in the Netherlands or elsewhere in Europe.
Nebius has an expanding European infrastructure footprint, including a proposed major data centre development near Rotterdam. That project has been separately reported by DataCentral following an agreement connected with a planned campus of up to 600MW.
Its potential capacity remains subject to the delivery of the physical development and supporting infrastructure. The existence of a commercial agreement or financing arrangement does not establish that the full amount of electricity or computing equipment is already operational.
Across Europe, projects continue to face constraints associated with grid connections, specialist construction, long lead equipment and the availability of suitable sites. A company’s access to finance can support procurement and development but cannot remove every external dependency.
Continued investment also increases the importance of operational resilience. As computing estates expand, network reliability, equipment maintenance and the ability to manage faults across multiple facilities become recurring operating costs alongside new capital expenditure.
Nebius’s latest financing adds resources for the immediate development programme, while the company’s longer-term performance will depend on matching contracted customer demand with the timely delivery of operating infrastructure and sustainable financing arrangements.
