Nebius reports November 12. Its $3.5 billion Citi loan comes due October 2027.

Early today Nebius▼−11.53% — Nebius, down 11.53 percent today Group, the Amsterdam-headquartered AI cloud listed on Nasdaq, fixed its third-quarter report for Thursday, November 12, before market open↗ ¹. The date matters more than the ritual. The stock is up 103% in 2026 through Wednesday's close↗ ², but it fell about 6% in Thursday's pre-market ³ and 7.4% in a single session this week ⁶, and the print is the first hard read on whether customers are still paying up front for a buildout the company is partly funding on a one-year loan ².

The buyer just said later

Microsoft▼−1.66% — Microsoft, down 1.66 percent today, Nebius's largest customer under a contract worth $17.4 billion to $19.4 billion ², spent $45.2 billion on capital expenditures and finance leases last quarter, about 30% more than a year earlier but short of the $50.7 billion analysts expected ⁴.

Finance chief Amy Hood told analysts that "some third-party capacity deliveries we expected in Q1 were delayed,"↗ and said the delays "have to do with GPU-as-a-service providers" ⁴, the category Nebius sells into. The money is not going away: Microsoft guided to more than $50 billion of capex in its current quarter and about $170 billion for calendar 2027 ⁴. But the largest tenant of rented GPU capacity has told the market its third-party machines are arriving late.

The lender's clock is shorter

On October 22 Nebius agreed a $3.5 billion senior secured facility↗ with Citi▼−3.16% — Citi, down 3.16 percent today: 364 days, maturing October 16, 2027, priced at SOFR plus 2.75% with the margin stepping up every 90 days to as much as 3.5%, secured by substantially all assets of the parent and two subsidiaries ⁵⁶. Chief operating officer Ophir Nave called it near-term construction capital, with longer-dated financing to follow ⁵.

Then the mood turned. Elon Musk said debt markets had "almost entirely shut off access to money" for neoclouds without revenue outside data centers, predicting "guppy-level death" among more than 200 providers ²³. And on Monday chief executive Arkady Volozh said certain asset-backed funding sources and access to debt markets had been temporarily shut↗ ⁶. Piper Sandler cut its price target to $185 from $237 while keeping a Neutral rating on October 21 ⁶.

The gap the loan has to bridge

The filings show it plainly. From March 2025 to June 2026, Nebius's quarterly debt rose from $0.19 billion to $10.06 billion and quarterly capex from $0.54 billion to $5.65 billion, against quarterly revenue that reached $582 million ⁷. Analysts expect about $906 million of revenue for Q3, and the number that matters most is deferred revenue, the prepayments customers hand over before capacity runs: $6.0 billion at June 30, up from $1.6 billion at the end of 2025 ².

Prepayments are the bull case

If that keeps growing, prepayments and the $40 billion of investment-grade contracts can plausibly carry the buildout to refinancing; if it flattens, the company enters the year the Citi loan comes due needing more stock or more debt ²⁵. The counterargument is real: Hood still says demand exceeds supply ⁴, analysts have trimmed 2027-2030 estimates by less than 2% since September 30 ², and Nebius's net debt of about $0.5 billion at June 30 was a rounding error next to CoreWeave's▼−11.15% — CoreWeave, down 11.15 percent today $29.5 billion on the same basis ². The borrowing against Microsoft and Meta was already on the record ⁸; what is new since October 22 is the loan's short clock and, since October 28, the buyer's own delay notice. A buyer taking delivery later and a lender wanting its money back sooner are two clocks running on the same machine.

What November 12 has to show

Watch deferred revenue first, connected power second: management targets 800 MW to 1 GW connected by year-end and $7 billion to $9 billion of annualized revenue by December ⁵². If the print shows both, the facility is construction capital. If not, it is a deadline.
