Nebius Is Not CoreWeave, but Its Funding Model Still Carries Risk

Nebius fell alongside CoreWeave during the October selloff in AI infrastructure stocks, even though the two companies do not carry the same financing structure. The market’s reaction was understandable: both businesses must spend heavily before new data-center capacity produces cash. The relevant question is how that spending is funded.

Nebius completed a roughly $775 million senior secured facility in July 2026. The debt is backed by deployed GPU infrastructure and cash flows from an investment-grade customer contract, matures in October 2030 and carries pricing of SOFR plus 2.50%. Nebius said the customer cash flows and financing together cover more than 100% of the capital expenditure for the underlying deployment.

That asset-level structure limits the usefulness of comparing a single net-debt number. It ties borrowing to identifiable equipment and contracted revenue. Nebius also said it had more than $40 billion of additional contracted revenue with investment-grade customers including Microsoft and Meta, which it expects to support similar financing.

CoreWeave’s June filing shows a more extensive stack. Its facilities included delayed-draw capacity of $8.5 billion and $3.1 billion added in 2026, plus $5.1 billion of equipment and software financing outstanding at June 30. Some facilities are guaranteed by the parent, while the $8.5 billion facility is largely non-recourse. The mix matters more than a single headline figure because maturities, guarantees and customer contracts determine which risks reach shareholders.

Nebius is therefore not simply a smaller CoreWeave. Its first secured facility demonstrates access to relatively low-spread, contract-backed capital. It does not remove construction, customer-concentration or refinancing risk. Management still must deliver capacity on schedule, keep utilization high and avoid funding long-lived assets with capital that reprices too quickly.

Investors should watch the terms of each new facility rather than assuming all AI-cloud debt is equivalent. Pricing near the July structure would support the argument that lenders view Nebius’ contracted deployments as bankable. A sharp increase in spreads, weaker covenants or more parent-level guarantees would show that the balance-sheet distinction is narrowing.
