Nebius and CoreWeave carried $19.4 billion of deferred revenue at 30 September 2026, nearly twice the $9.8 billion at the end of 2025, by our arithmetic from Nebius’s third-quarter results and CoreWeave’s 10-Q. Nebius’s shareholder letter says it expects $17 billion to $20 billion of customer prepayments in 2027, which is 38% to 50% of its $40 billion to $45 billion of 2027 capital spending, by our arithmetic.
Customers are paying for AI capacity before it is built. “Customers are increasingly financing the AI infrastructure they’re contracting to use”, Shanu Mathew, who posts on AI power and data centres, wrote on X on 13 November. The money also runs the other way: Nvidia’s 10-Q shows $42.4 billion of equity purchases in the six months to 26 July, 60.6% of its free cash flow, by our arithmetic. We read the filings behind both flows.
Business Pill · Vendor Guarantees Explained
An evergreen Business Engineer explainer on who carries the risk after the sale. It teaches the concept with a chip-financing example and does not discuss Nebius, CoreWeave or the filings in this piece.
The key insight: As we read the filings, the AI cloud build is now financed from both ends: customers prepay Nebius and CoreWeave for capacity, leaving $19.4 billion of deferred revenue between them at 30 September, by our arithmetic, while Nvidia spent 60.6% of its six-month free cash flow on equity purchases, by our arithmetic.
Nebius’s letter, dated 12 November, says: “Prepayments are now the standard structure of our agreements.” It expects $10 billion of committed customer prepayments in 2026, rising to $17 billion to $20 billion in 2027, and adds: “The 2027 range is not a ceiling.” Against capital spending of approximately $27 billion this year, the 2026 prepayments come to 37%, by our arithmetic.
The letter says prepayments on deals signed in the third quarter covered more than 100% of the associated capital spending, up from 50% to 60% in the second quarter, and that more than 90% of contract value signed in the quarter carried a prepayment. “customers are meeting our terms: bigger deals, for longer, at higher prices, and with more paid up front”, the letter says.
Prepayments and asset-backed financing of existing investment-grade contracts are expected to fund 75% to 85% of 2027 capex. Our piece on Nebius’s 2027 capex guide covers the revenue side.
Capital spending guidance against the customer prepayments each company expects. Nebius: about $27 billion of 2026 capex and $10 billion of committed 2026 prepayments; $40 billion to $45 billion of 2027 capex and $17 billion to $20 billion of 2027 prepayments (range midpoints drawn), from its Q3 2026 shareholder letter. CoreWeave: a 2026 capex guide of $37 billion to $39 billion and about $9 billion of prepayments and deposits expected in the three months from its 10 November call. The shares of capex, 37%, 38% to 50% and 23% to 24%, are our arithmetic; CoreWeave’s compares a three-month figure with a full-year guide.
What Was Posted on X
Nebius expects $17–20B of customer prepayments in 2027. CoreWeave expects ~$9B over the next three months. Customers are increasingly financing the AI infrastructure they’re contracting to use.
I’ve seen people discuss the Bull read: Customers are committing cash to secure capacity. Prepayments reduce the provider’s funding requirement, while signed contracts support secured borrowing at better terms than unsecured corporate debt. CoreWeave says its contracted cash flows should cover costs and repay debt before counting renewals. If that underwriting holds, the initial customer contract pays for the infrastructure and subsequent bookings generate additional returns.
Seen less on the Bear read: Expensive unsecured funding is pushing more of the cash requirement onto customers. For AI labs, that means paying for compute before generating the revenue needed to support it. The supplier’s liquidity improves, while the customer commits more of its available cash upfront.
If demand disappoints, spreading customer payments over more years may also require lenders to extend repayment schedules. The GPUs keep depreciating during that negotiation too btw!
Customer quality becomes central. A contract supported by a cash-generating hyperscaler has a different funding profile from one supported by a lab dependent on further capital raises.
The market can reasonably read rising prepayments as evidence of scarce capacity and stronger supplier bargaining power. Sustaining those terms depends on customers continuing to earn enough from the compute, or continuing to attract capital to fund it.
Shanu Mathew, who posts on AI power and data centres, wrote at 16:06 UTC on 13 November that Nebius expects $17 billion to $20 billion of customer prepayments in 2027 and CoreWeave about $9 billion over the next three months, and set out a bull and a bear read. This piece checks both figures in the companies’ own documents and adds their balance sheets.
Why the Neoclouds are getting smoked: “a big chunk of Nvidia’s $50-60BN in quarterly free cash flow gets recycled straight back into customers, suppliers and neoclouds, and even a temporary pause could pull $50BN or more out of the AI ecosystem. Think of it as QT for the AI trade, announced by press release at 8:48am.”
ZeroHedge posted at 16:04 UTC on 13 November a quoted note saying a big chunk of Nvidia’s quarterly free cash flow is recycled into customers, suppliers and neoclouds. This piece compares the note’s figure with Nvidia’s latest 10-Q, which it treats as the primary source.
CoreWeave’s Next Three Months
On its 10 November earnings call, CoreWeave’s chief executive Mike Intrator said: “In the current environment, prepayments are more attractive.” Intrator added: “This year, we have collected prepayments on 70% of our deals, with customers funding up to 100% of the contract value upfront.”
Chief financial officer Nitin Agrawal said: “We expect approximately $9 billion of customer prepayments and deposits in the next three months alone, and for that number to continue to grow in 2027.” That is 23% to 24% of CoreWeave’s 2026 capital spending guide of $37 billion to $39 billion, by our arithmetic, collected in a single quarter. Intrator said more than $3 billion of the $9 billion is prepayment for existing infrastructure “that has been fully paid off”, so less than $6 billion relates to new capacity, by our arithmetic. Our piece on CoreWeave’s $9 billion of prepayments has the call in full.
Deferred revenue, current plus non-current, at 31 December 2025 and 30 September 2026, from Nebius’s third-quarter results release and CoreWeave’s 10-Q. Nebius rose 6.0 times and CoreWeave 1.2 times; the combined $19.4 billion and the multiples are our arithmetic.
Booked Is Not Yet Collected
Deferred revenue is money billed or received before the service is delivered. At Nebius it rose to $9.41 billion at 30 September from $1.58 billion at the end of 2025, 6.0 times, by our arithmetic from the balance sheet. In the third quarter alone, the cash flow statement shows deferred revenue up $3,434.0 million while accounts receivable rose $3,761.8 million, and operating cash flow was an outflow of $273.0 million.
At CoreWeave, the 10-Q puts deferred revenue at $10.0 billion at 30 September, against $8.2 billion at the end of 2025. It also says $1.9 billion of the opening balance was reclassified to customer liabilities “as contracts became cancellable during the quarter”. The 10-Q says CoreWeave has “received and may continue to seek upfront payments from customers under committed contracts in connection with the deployment of capacity for those customers”.
Micron shows the same pattern in memory, as our piece on Micron’s customer deposits sets out. Mathew’s post also gave the bear read: “For AI labs, that means paying for compute before generating the revenue needed to support it.”
The Other Direction: Nvidia Funds Its Customers
The supplier is financing the buyers too. Nvidia’s 10-Q for the quarter to 26 July shows operating cash flow of $74.4 billion in the first six months of the fiscal year and $4.4 billion of property and equipment purchases, which leaves free cash flow of about $70.0 billion, by our arithmetic. In the same six months it spent $42.4 billion on purchases of equity securities, 60.6% of that free cash flow, by our arithmetic.
Its non-marketable equity securities, “primarily in privately-held companies”, rose to $47.9 billion from $22.3 billion over the six months. In August, Nvidia entered into guarantees capped at $105 billion “to provide credit support on a land, power, and shell buildout” on behalf of a customer, an affiliate of OpenAI, the 10-Q says. Under its AI cloud agreements, Nvidia says: “if AI clouds do not successfully sell committed capacity to third-party customers, we have agreed to purchase that capacity.” Those commitments totalled $36 billion. Our tally of Nvidia’s deal pledges lists the deals.
A note quoted by ZeroHedge on X said “a big chunk of Nvidia’s $50-60BN in quarterly free cash flow gets recycled straight back into customers, suppliers and neoclouds”. The latest 10-Q averages about $35.0 billion of free cash flow a quarter over the six months, by our arithmetic, below the note’s range. Our explainer on how AI clouds borrow sets out the debt options.
The Structural Read
As we read Nebius’s guide, prepayments move part of the funding burden from the cloud to its customers: the 2027 prepayments it expects equal 38% to 50% of its 2027 capex, by our arithmetic, and the letter says the 2027 range is not a ceiling.
As we read CoreWeave’s 10-Q, the deferred revenue is not all locked in: $1.9 billion moved to customer liabilities as contracts became cancellable during the quarter, so the balance can shrink as well as grow.
Nebius Group, Letter to shareholders, Q3 2026
“We receive them well in advance, which gives us visibility into our funding.”
Three Implications
FOR AI LABS AND OTHER BUYERS CoreWeave said customers funded up to 100% of contract value upfront on some deals this year, and Nebius said more than 90% of third-quarter contract value carried a prepayment.
FOR LENDERS Nebius said prepayments and asset-backed financing of investment-grade contracts are expected to fund 75% to 85% of its 2027 capex; CoreWeave said it expects asset-level debt to cover most of its remaining needs.
FOR INVESTORS Year-end balance sheets will update both deferred revenue figures, and Nvidia’s next 10-Q will update its equity purchases and its AI cloud commitments.
The framework’s thesis: “the capex race is no longer a corporate spending cycle. It is a sovereign-scale financing problem dressed in tech-company clothing — and the financial architecture is starting to invert.”
As we read it, customer prepayments at Nebius and CoreWeave and Nvidia’s equity purchases are two signs of that inversion at company scale. The framework predates these results and does not discuss Nebius, CoreWeave or Nvidia’s 10-Q.
What Is Not Established
Deferred revenue is not the same as cash collected, and Nebius’s receivables grew faster than its deferred revenue in the third quarter. The prepayment figures for 2027 and for CoreWeave’s next three months are company expectations, not results. CoreWeave’s $9 billion covers a three-month window and its capex guide a calendar year, so the 23% to 24% compares different periods.
Nvidia’s 10-Q reports equity purchases in aggregate and does not say how much went to its own customers; its next 10-Q, for the quarter to late October, was not on SEC EDGAR when we checked on 13 November. Mathew’s post and the note ZeroHedge quoted are commentary, and the note’s author is not named in the post. We did not contact Nebius, CoreWeave or Nvidia for this piece.
This Week In The AI Supercycle
The Great Convergence of Capital, Power, and Geopolitics
This week’s issue: for two years the AI build-out was priced as a supply story, and last week as a credit story. This week it was priced as a permission story, and the answer arrived as a cost, not a ban.
Nebius and CoreWeave carried $19.4 billion of deferred revenue at 30 September, by our arithmetic, and both say customer prepayments are now a main way to fund the build: 38% to 50% of Nebius’s 2027 capex and about $9 billion at CoreWeave in three months. Nvidia, on the supplier side, put $42.4 billion into equity purchases in six months. The next figures to watch are Nebius’s and CoreWeave’s year-end deferred revenue and Nvidia’s 10-Q for the quarter to late October.

A note on sourcing. We read, on 13 November 2026, Nebius Group’s third-quarter 2026 letter to shareholders and results release, CoreWeave’s transcript of its 10 November earnings call and its 10-Q for the quarter to 30 September 2026, and Nvidia’s 10-Q for the quarter to 26 July 2026 on SEC EDGAR. The story was prompted by posts on X from Shanu Mathew and ZeroHedge, which we treat as commentary.
The combined deferred revenue, the multiples, the shares of capital spending, Nvidia’s free cash flow and the share spent on equity purchases are our arithmetic. Prepayment figures for future periods are the companies’ expectations. We did not contact Nebius, CoreWeave or Nvidia for this piece.
