Nebius’s $3.5 billion Citi facility puts a one-year clock on GPU expansion

Nebius has secured access to $3.5 billion for GPU infrastructure and other corporate needs, with a repayment deadline of 16 October 2027. The Citi facility, disclosed on 22 October, is a bridge between spending on capacity now and arranging longer-term funding. Its rising interest margin makes that timetable part of the price.[1][2]

The agreement was signed on 17 October. It provides a senior secured term-loan facility of up to $3.5 billion; the disclosed size is capacity to borrow, not a statement that the entire amount has already been drawn. The borrowers’ assets provide security, subject to specified exceptions.[1][2]

The rate increases as the calendar advances

According to the filing, the facility initially charges Term SOFR plus 2.75 percentage points per year. The margin rises by 0.25 percentage points each 90 days after the agreement date, up to 3.50 percentage points, subject to adjustments. It is a floating-rate arrangement, not a fixed 2.75% loan. The final interest cost depends on the SOFR benchmark, the actual amount drawn, the time the balance remains outstanding and other contractual terms.[1][2]

As a simple illustration—not a calculation of Nebius's actual bill—2.75% of $3.5 billion is $96.25 million annually, before the SOFR benchmark and other terms. At a 3.50% margin, that margin component alone would be $122.5 million on an unchanged fully drawn balance for a full year. The difference illustrates why lenders can price a bridge facility to encourage replacement with longer-term funding. Neither illustrative number says how much Nebius will actually borrow or pay.[1][2]

The agreement provides for voluntary prepayment without premium or penalty. It also imposes a minimum-liquidity covenant. The collateral encompasses substantially all assets of the borrowers, with specified exclusions, including holdings in certain borrower subsidiaries. Those provisions become especially important if the timing of construction or fundraising shifts. A profitable long-term contract cannot necessarily solve a short-term cash requirement unless lenders will advance money against that contract on acceptable terms.[1][2]

What customers' promises can and cannot finance

Nebius says it has long-term customer commitments worth more than $40 billion with investment-grade counterparties, and it has pointed to potential asset-backed financing against those commitments. The number is a company's reported long-term contractual reference, not an immediately available cash balance. The period over which revenue is recognized, the conditions under which customers pay and the cost of delivering that capacity determine its financial significance. It would be an error to compare $40 billion of multi-year commitments directly with a one-year debt facility as though both were the same type of asset.[1][2]

The appeal of the bridge is clear. Accelerating construction may allow a company to capture GPU demand while the market is capacity-constrained. The danger is also clear. Equipment generations change, energy infrastructure takes time, and the market price of a unit of compute could fall if supply rises or models become more efficient. A datacentre can have customers and still be an unattractive investment if the financing and operating costs eat too much of the return.[1][2]

Nebius describes the loan as part of a funding sequence that also includes customer prepayments and operating cash flow. In its announcement, it points to asset-backed finance against long-term customer commitments as another potential source. The bridge buys flexibility over when and how to arrange those later transactions.[1][2]

The asset timetable and the debt timetable

A large borrowing figure tells us almost nothing about economic efficiency unless paired with units of delivered capacity and their cash generation. Useful measures would include dollars of funded debt per megawatt or GPU capacity, average utilization, gross margin after power and maintenance, customer concentration, and how reliably contracted customers translate into payments. A lender may be comfortable with a high nominal loan if well-underwritten cash flows support it; a smaller facility can be risky if the promised utilization never arrives.[1][2]

The immediate achievement is access to capital that can bring capacity forward. The test arrives on the financing schedule: assets intended to earn over several years must be supported by cash generation, repayment or replacement funding when this facility matures.[1][2]
