CoreWeave’s 9.625% notes due 2032 traded at a 14.21% yield on 11 November, according to FINRA TRACE data, as our loan piece reported. The day before, chief executive Mike Intrator said the company “will not use the unsecured debt market to fund our business at current yields”.
Instead, CoreWeave is leaning on its customers. It said it expects about $9 billion of prepayments and deposits in the next three months, about 95% of the $9.44 billion it spent on property and equipment in the third quarter, by our arithmetic. Nebius said it expects $17 billion to $20 billion of customer prepayments in 2027.
Business Pill · Free Cash Flow Explained
An evergreen Business Engineer explainer on free cash flow, the cash left after capital spending. It teaches the general idea only and does not discuss CoreWeave or Nebius.
The key insight: As we read the week, the neoclouds are changing whose credit stands behind the build: CoreWeave’s unsecured notes yielded 14.21%, while customer cash it expects in three months equals 95% of a quarter’s capital spending, by our arithmetic.
CoreWeave booked $2,022 million of net interest expense in the first nine months of 2026, about 144 times its $14 million of operating income, by our arithmetic from its results release (our interest piece). Its debt other than convertibles carried an average effective rate of about 9.9% at 30 June, by our arithmetic from its 10-Q (our rate piece).
The 10-Q for the quarter to 30 September shows $10.974 billion of principal due in 2027, up 77% from the previous filing, and total principal of $47.5 billion (our debt schedule piece). In the third quarter, capital spending was 4.8 times operating cash flow and free cash flow was about negative $7.5 billion, by our arithmetic (capex, cash burn).
What CoreWeave pays to borrow: the yield on its 9.625% notes due 2032 in FINRA TRACE data on 11 November 2026, the average effective rate on its non-convertible debt at 30 June (our arithmetic from its 10-Q), and its finance chief’s guide for its next investment-grade loan (10 November call).
Borrowing Against Contracts
CoreWeave plans to raise at least $4 billion through an investment-grade loan, Bloomberg reported on 11 November. Its finance chief guided the next such loan to a 7% to 7.5% yield, about half the 14.21% on its unsecured notes, by our arithmetic. Intrator said it expects “approximately $9 billion in prepayments and deposits from signed customer contracts” (our call piece).
The two companies carried $19.4 billion of deferred revenue at 30 September, nearly twice the $9.8 billion at the end of 2025, by our arithmetic (our deferred revenue piece). Nebius’s expected $17 billion to $20 billion of 2027 prepayments is 38% to 50% of its $40 billion to $45 billion of 2027 capital spending, by our arithmetic (our Nebius piece).
CoreWeave’s revenue backlog was about $132.5 billion at 30 September, up 27% in a quarter, by our arithmetic (our results piece). As we read it, concentration runs through the layer too: at Cerebras, three customers made up 79% of its third-quarter revenue, by our arithmetic from its 10-Q (our Cerebras piece).
The Market’s Week
By Friday’s close, CoreWeave and Nebius had lost $15.6 billion of market value since the 11 November close, by our arithmetic on the share counts in their latest filings: $4.2 billion at CoreWeave and $11.4 billion at Nebius (our close update).
The Structural Read
As we read the filings, prepayments and deferred revenue lean on the customer’s contract rather than the neocloud’s own name, and the guide for the next investment-grade loan, 7% to 7.5%, is about half the unsecured yield.
As we read the Nebius and Cerebras figures, the reliance on a few large customers runs through the layer: Nebius plans to fund 38% to 50% of its 2027 spending with prepayments, and three customers made up 79% of Cerebras’s third-quarter revenue, by our arithmetic.

“Looking ahead, we will not use the unsecured debt market to fund our business at current yields. Nor do we need to”
Three Implications
FOR CREDIT INVESTORS CoreWeave’s 9.625% 2032 notes traded at a 14.21% yield on 11 November, FINRA TRACE data show; its loan guide is 7% to 7.5%.
FOR AI LABS AND OTHER CUSTOMERS Nebius expects $17 billion to $20 billion of customer prepayments in 2027, 38% to 50% of its planned capital spending, by our arithmetic.
FOR NEOCLOUD SHAREHOLDERS CoreWeave and Nebius lost $15.6 billion of market value from the 11 November close to Friday’s, by our arithmetic.
The framework’s central line: “The $1T capex cycle is being underwritten by a $1T concentrated demand commitment from two counterparties whose combined free cash flow is deeply negative.”
As we read it, the neoclouds’ move to customer cash ties their funding more closely to those counterparties. The framework does not discuss this week’s loan, yields or prepayment figures.
Customer prepayments the companies expect, against their capital spending: CoreWeave’s 10 November call and third-quarter release; Nebius’s 12 November shareholder letter. Shares are our arithmetic.
What Is Not Established
The 14.21% is one day’s trade in one bond. The $9 billion of prepayments and the investment-grade loan are the company’s expectation and plan, not completed transactions, and the loan’s final terms are not public. Share prices do not show what drove each move.
We read our earlier pieces built on the companies’ filings, releases and call transcripts; none of the companies was contacted for this piece.
This Week In The AI Supercycle
AI Lost Its Central Banker, the Lab Oligopoly, and the Future of Open Source
This week’s issue: the Nvidia leadership change, read as the AI build-out losing its central banker: who now finances the GPU landlords, backstops the data centres and sponsors open models, and why two labs are becoming the bank.
CoreWeave’s unsecured notes yielded 14.21% on 11 November and its nine-month interest bill was 144 times operating income, by our arithmetic. It now expects about $9 billion of customer prepayments in three months, 95% of a quarter’s capital spending, and Nebius expects $17 billion to $20 billion in 2027; the two hold $19.4 billion of deferred revenue.
A note on sourcing. This analysis combines eleven of our pieces from 10 to 13 November, each built on the companies’ own filings, releases and call transcripts, Bloomberg’s report and FINRA TRACE data, with our 13 November close update. Shares, ratios and multiples are our arithmetic. Yields and share prices are market data.
