CoreWeave owes $10.974 billion of debt principal in 2027, up 77% from the $6.184 billion its previous quarterly report listed, by our arithmetic, according to its Form 10-Q for the quarter ended 30 September, filed with the SEC on 12 November. Principal due from October 2026 through the end of 2028 now adds up to $18.9 billion, against $15.0 billion in the June filing.
Total debt principal reached $47.5 billion at 30 September, up from $35.6 billion at 30 June. Undrawn availability under its credit facilities fell to $5.7 billion from $10.0 billion, the two filings say.
Business Pill · Backlog
An evergreen Business Engineer explainer on backlog: revenue that is signed but not yet earned. It teaches the general idea only and does not discuss CoreWeave’s filing.
The key insight: As we read the two filings, CoreWeave added $3.9 billion of principal due through 2028 in one quarter while the backlog it expects in the next 24 months grew about $5.1 billion, by our arithmetic, so debt due through 2028 now equals about 40% of that near-term backlog, up from about 35%.
The new schedule lists $2.433 billion for the rest of 2026, $10.974 billion in 2027, $5.479 billion in 2028, $4.727 billion in 2029, $4.247 billion in 2030 and $19.645 billion after that. The June 10-Q listed $4.413 billion for the rest of 2026, $6.184 billion in 2027 and $4.416 billion in 2028.
Counting only the rest of 2026 and 2027, $13.4 billion is due, against $10.6 billion in the June schedule, by our arithmetic. Debt classed as current, recourse and non-recourse together, rose to $10.572 billion from $7.513 billion.
The debt table shows what was added. OEM and software license financing on the recourse side rose to $6.891 billion from $3.518 billion at the end of 2025, with maturities from December 2026 to July 2030. New lines include the $2.749 billion DDTL 5.0 facility, repaid monthly from November 2026, the $1.555 billion DDTL 5.5 facility and $4.583 billion under the non-recourse DDTL 4.0 facility.
The filing gives effective interest rates by line: 15% on DDTL 1.0, due March 2028; 11% on DDTL 5.5; 10% on the OEM and software license financing; and 2% to 3% on the three convertible notes. On 7 November we reported the June schedule, which then added up to $15.0 billion through 2028.
Future principal payments on CoreWeave’s total debt by calendar year, as listed in its 10-Qs for the quarters ended 30 June and 30 September 2026. The rest-of-2026 bar covers July to December in the June filing and October to December in the September filing. The 77% rise in 2027 payments is our arithmetic.
Against the Backlog
The 10-Q puts remaining performance obligations, the contracted revenue not yet delivered, at $132.3 billion. It expects 36% to be recognised in the 24 months ending 30 September 2028, 38% in months 25 to 48 and the rest in months 49 to 86.
That is about $47.6 billion in the first 24 months, by our arithmetic, against about $42.5 billion in the June filing, when the share was 41% of $103.7 billion and the last window ended at month 78. The near-term slice grew by about $5.1 billion while principal due through 2028 grew by $3.9 billion.
By our arithmetic, the $18.9 billion due through December 2028 equals about 40% of the $47.6 billion of backlog expected by September 2028, up from about 35% in June. The windows do not match exactly; the debt schedule runs three months longer. Our results piece used the release’s approximately $132.5 billion backlog figure.
Customers and Cancellable Contracts
One customer, labelled Customer B, accounted for 30% of third-quarter revenue and another, Customer A, for 24%, the 10-Q says. In the June quarter Customer A was 36%, Customer B 26% and Customer C 10%. The filing warns that “The customer references of A through D may represent different customers than those reported in a previous period”.
The two largest customers made up 54% of revenue in the third quarter against 62% in the second, by our arithmetic. At 30 September Customer B held 33% of accounts receivable and Customer A 18%.
Deferred revenue, which holds customer prepayments, was $10.0 billion at 30 September against $9.7 billion at 30 June. The filing adds that $1.9 billion “of the deferred revenue balance from the beginning of the period was reclassified from deferred revenue to customer liabilities, which are included in other current liabilities, as contracts became cancellable during the quarter”.
Customer liabilities stood at $1,915 million, against $137 million at the end of 2025. The $1.9 billion is about a fifth of the June deferred revenue balance, by our arithmetic. On its call CoreWeave said it expects about $9 billion of prepayments and deposits in the next three months.
Covenants, Cash and Rumors
CoreWeave says it was “in compliance with all covenants under its loan agreements” at 30 September. It held $4.2 billion of cash, cash equivalents and marketable securities, plus $2.3 billion of restricted cash, and says its cash and available borrowing “will be sufficient to meet our obligations due or anticipated to be due within one year” of the filing.
A new risk factor names October. It says the trading prices of its stock and “of certain of our outstanding notes declined significantly and market yields on certain of our notes increased substantially due in part to negative publicity and market rumors about our company, our use of indebtedness” and the ability of AI companies to obtain financing, as well as broader market conditions.
The 10-Q also says no shares were sold under its at-the-market program in the quarter, leaving 35 million available. We reported on 11 November on CoreWeave’s plan for a $4 billion investment-grade loan.
The Structural Read
As we read the schedule, 2027 is now the heaviest single year before 2031: $10.974 billion, against $5.479 billion in 2028, while undrawn availability fell to $5.7 billion from $10.0 billion.
As we read the deferred revenue note, the $1.9 billion moved to customer liabilities is prepayment money tied to contracts the filing says became cancellable during the quarter; the filing does not say which contracts.
CoreWeave Form 10-Q, quarter ended 30 September 2026
“We have a substantial amount of debt, which requires significant interest and principal payments.”
Three Implications
FOR LENDERS The 10-Q lists $2.433 billion of principal for the rest of 2026 and $10.974 billion in 2027, and says CoreWeave was in compliance with all covenants at 30 September.
FOR THE BACKLOG The filing expects 36% of the $132.3 billion backlog in the next 24 months, down from 41% in June, with the last window now running to month 86.
FOR CUSTOMERS Customer B made up 30% of third-quarter revenue and Customer A 24%; the filing says the letters may refer to different customers than in June.
The framework says: “the capex race is no longer a corporate spending cycle. It is a sovereign-scale financing problem dressed in tech-company clothing”.
As we read it, CoreWeave’s maturity schedule is that financing problem at company scale: $47.5 billion of debt principal set against $132.3 billion of contracted revenue. The framework predates this filing and does not discuss CoreWeave’s 10-Q.
CoreWeave figures from its 10-Qs for the quarters ended 30 June and 30 September 2026. Debt due through 2028 sums the filings’ yearly schedules; 24-month backlog applies the filings’ 41% and 36% to $103.7 billion and $132.3 billion; the percentage changes are our arithmetic.
What Is Not Established
The 10-Q does not name Customers A to D in the passages we read, and says the letters may refer to different customers than in June, so the share changes may not describe the same companies. The sentence on the $1.9 billion does not say which contracts became cancellable or why. We did not contact CoreWeave 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.
CoreWeave’s September 10-Q lists $10.974 billion of principal due in 2027, 77% more than its June filing, and $18.9 billion through 2028, about 40% of the backlog it expects to recognise in the next 24 months by our arithmetic. It also moved $1.9 billion out of deferred revenue as contracts became cancellable.
A note on sourcing. We read CoreWeave’s Form 10-Q for the quarter ended 30 September 2026, filed with the SEC on 12 November, in full, and compared it with the matching sections of its 10-Q for the quarter ended 30 June 2026. Sums across years, percentage changes, backlog dollar windows and ratios are our arithmetic. CoreWeave was not contacted for this piece.
