CoreWeave's $41.6B Debt Outweighs Its Demand Edge Over Nebius

CoreWeave booked $3.66 billion of third-quarter revenue, up 168.3%, and still ended the quarter with a $709 million GAAP net loss. The gap between those two numbers sits on the balance sheet: $41.6 billion of corporate debt and $846 million of net interest expense.

Nebius Group reported $980.8 million of revenue, up 571.3%, with a net loss of $37.5 million. The two companies published third-quarter results two days apart. Both said demand for AI compute exceeds the capacity they can bring online.

So the divergence is not demand. It is funding.

How do the two quarterlies compare?

Metric	CoreWeave	Nebius
Q3 net loss	$709M	$37.5M
Cash	$4.12B	$7.43B
2026 capex guide	$37–$39B	~$27B
Demand signal	~$132.5B backlog	$12B+ signed since Q3 began

CoreWeave says qualified demand runs at 10 times available capacity through the end of 2027. The company raised prices by roughly 25% in July and another 10% later in the quarter. Adjusted operating margin reached 10%, a quarter ahead of plan. Interest expense, guided to $1.05–$1.15 billion for the fourth quarter, is what turns that operating profit into a reported loss.

What does CoreWeave's debt change for shareholders?

CoreWeave's chief financial officer told analysts: "we will not use the unsecured debt market to fund our business at current yields, nor do we need to." Management expects less than $5 billion of parent-level capital through 2027, plus roughly $9 billion of customer prepayments and deposits arriving in the next three months.

That funding mix does not remove the leverage. A debt-to-equity ratio of 8.94 leaves shareholders with a thin buffer, and a share issuance program covering up to 35 million shares adds dilution on top of it.

Can prepayments replace bonds?

Nebius is trying the same trade with a different instrument. CEO Arkady Volozh said: "prepayments on Q3 agreements covered more than 100% of the associated capex." On paper that is the cleaner model, since customers fund the build before the assets exist.

The cash flow did not yet follow. Nebius operating cash flow came in at negative $273 million, and the company added $5.75 billion in convertible notes. Convertibles buy time, but they convert into shares later.

Where does each company's growth actually come from?

Nebius reported a rocky quarter. About $325 million of revenue came from a non-recurring, asset-light deal, which inflates the headline relative to the recurring business. Colocation delays in New Jersey pushed 2026 revenue guidance to the low end of the $3.0–$3.4 billion range. Prices rose more than 20% per GPU-hour against the second quarter, and Databricks, Datadog and Snowflake signed multi-year contracts.

CoreWeave's renewal book is the item to watch. More than 130,000 GPUs come off contract in 2027, and management says renewing them could add close to $4 billion of annualized revenue with no new capex. For Nebius, the test is whether its own sites in Missouri, Alabama and Finland deliver $12–$13 billion of 2027 revenue and pre-tax breakeven in the fourth quarter of 2027.

Why did Nebius fall harder?

Investors punished Nebius more on Thursday. Its shares fell 16.84% to $128.64. CoreWeave fell 6.86%.

One reading of that reaction: it punishes a timing problem and misses a more durable advantage. Nebius holds more cash, reported a much smaller loss and carries $12.30 billion of shareholders' equity. CoreWeave holds the larger backlog, but interest costs absorb much of its operating profit. If renewals land and interest expense stops climbing, CoreWeave's balance-sheet risk eases. Until then, CoreWeave carries the greater leverage against the same demand.

What does this change for investors in either name?

Watch four line items in the next filings: prepayments actually received, renewal conversions on the 130,000 expiring GPUs, quarterly interest expense, and the pace of capex against the $37–$39 billion and ~$27 billion 2026 guides. Both companies sit at the chip layer of the buildout. The power, thermal and connectivity suppliers downstream of them are a separate trade.

And keep the two funding models distinct. CoreWeave runs on debt and customer prepayments with a 8.94 debt-to-equity ratio. Nebius runs on prepayments and convertible notes with $7.43 billion of cash. Same demand cycle, different balance-sheet risk.
