FOURWEEKMBA EXPLAINER · FROM THE NEWSROOM · UPDATED 12 NOVEMBER 2026
The short answer: AI cloud companies borrow in two places. Inside a special-purpose subsidiary that owns the servers and one customer’s contract, lenders are mostly betting on the customer, so the loan can be investment grade: CoreWeave’s DDTL 4.0 is rated A3 and floats at SOFR + 2.25%. At the parent company, unsecured notes are priced on the cloud company’s own credit, which is high yield: CoreWeave’s 9.625% notes due 2032 are rated B1, seven notches lower.

A neocloud (a company that rents out AI chips by the hour) spends billions on chips and servers and funds much of it with debt. It can borrow in two places.
At the asset level. The company sets up a separate subsidiary, a special-purpose vehicle (SPV). The SPV buys the servers and holds the customer contract that will use them. Lenders lend to the SPV, take a pledge over everything in it, and get repaid from the customer’s payments. If the parent company fails, the lenders still have the servers and the contract.
At the parent level. The company itself sells bonds. No asset is pledged. Bondholders are paid from whatever cash the whole company makes, so they price the company’s own credit.
CoreWeave’s finance chief, Nitin Agrawal, described the same split on the 10 November 2026 call: “debt that sits at the asset level, directly financing our customer contracts backed by committed cash flow and cloud infrastructure”, and “debt that sits at the parent company” (our newsroom’s explainer).
Asset level: SPV loanBorrower: a bankruptcy-remote subsidiary. Security: the servers, the SPV’s shares and the customer contract. Repaid by: the customer’s payments. Lenders’ risk: close to the customer’s. CoreWeave example: DDTL 4.0, A3.
Parent level: unsecured notesBorrower: the company itself. Security: none. Repaid by: the whole company’s cash flow. Lenders’ risk: the company’s own. CoreWeave example: 9.625% notes due 2032, B1 / B.
What a delayed draw term loan is
A delayed draw term loan (DDTL) is committed up front and drawn in stages, as servers are bought and installed. It suits AI clouds because the chips arrive in batches over months.
CoreWeave’s DDTL 4.0 is an $8.5 billion facility “available in one or more draws through June 30, 2027”, its 10-Q for the quarter to 30 June 2026 says. The loan is sized to the price of the equipment. It also requires a cash cushion: restricted cash covering “a forward-looking three-month coverage of scheduled cash interest and principal payments” (CoreWeave 10-Q).
Investment grade vs high yield
A credit rating is an agency’s view of how likely a borrower is to pay. S&P draws the line at BBB-: “BBB- and above” is investment grade; BB+ and below is speculative grade, which the market calls high yield (S&P). On Moody’s scale the line sits between Baa3 and Ba1 (Moody’s). Each step on the ladder is a “notch”.
The ladder below shows where AI cloud debt sits. Rating categories are from the agencies’ public scales; each placement is the rating the borrower disclosed or FINRA’s bond data lists.
B1 B+CoreWeave 9.625% notes due 2032: B1 (Moody’s)
B2 BSame notes: B (S&P)
Moody’s rating with the S&P/Fitch equivalent below it. Sources: CoreWeave releases of 31 March and 10 August 2026; IREN release of 1 June 2026; Lambda release of 27 August 2026; FINRA bond data read 11 November 2026 (via our newsroom). From A3 to B1 is 7 notches; from A3 to Ba2 is 5 (count on Moody’s scale).
Why a big customer makes the loan cheaper
In an SPV loan, the money that repays the lender comes from the customer’s contract. If the customer is a large, highly rated company, the risk the lender takes is close to that customer’s risk, not the cloud company’s. The servers and a cash reserve sit behind it as a second layer.
That is why the cheapest debt in this group names a big customer. IREN said its $3.65 billion June 2026 facility was “Anchored by Microsoft’s offtake”, rated A by Fitch and A(low) by DBRS, at a blended 6.00% (our newsroom). CoreWeave’s release named DDTL 4.0’s customer only as a “leading AI enterprise”; Bloomberg reported it is Meta. Lambda’s term loan B funds GPUs for an unnamed “investment-grade offtaker” (Lambda).
The customer’s quality is not the only factor. CoreWeave’s DDTL 5.5, signed on 7 August 2026, is backed by contracts that average about three years while the loan runs about five, so lenders carry what the release calls “renewal risk”. It is guaranteed by the parent, yet it rated Ba2 / BB+ and priced at SOFR + 5.50%, 3.25 points wider than DDTL 4.0. CoreWeave’s chief executive said its facilities have priced “from 225 to 550 basis points above SOFR with high-quality investment-grade customers at the tight end of that range and AI labs towards the wide end”.
Effective rates from each 10-Q’s debt note. IREN: $409M DDTL at 7.22% and $1,571M of notes at 7.09% (non-recourse, Microsoft agreement) vs $947M at 10.70% and $355M at 10.38% (parent-guaranteed, August 2026). Weighted averages are our arithmetic; CoreWeave’s 9.8% is our newsroom’s.
Worked example: CoreWeave’s DDTL 4.0
Every number below is from CoreWeave’s filings for 2026, as read by our newsroom (explainer, loan piece).
1 · The customer contractA “leading AI enterprise” signs for capacity (Meta, according to Bloomberg). Its payments are the main source of repayment.
↓ the contract and the servers go into one subsidiary
2 · The SPV: CoreWeave Compute Acquisition Co. VIIIHolds the servers and the contract. At 30 June 2026: $3.3B of non-current and $155M of current assets against $2,837M of DDTL 4.0 principal, about $1.22 of assets per $1 borrowed (newsroom arithmetic).
↓ lenders take a first-priority pledge of its shares and substantially all its assets
3 · The loan: DDTL 4.0, $8.5BNon-recourse to CoreWeave Inc. Rated A3 (Moody’s) and A (low) (DBRS). Floating tranche SOFR + 2.25%; fixed tranche about 5.9%; matures March 2032. Effective rate in the 10-Q: 7%.
↓ the customer pays; the loan amortises over the contract
4 · Repayment“The cash flow from those contracts pays interest and repays the principal over the contract term while generating additional cash flow for CoreWeave”, chief executive Michael Intrator said on 10 November 2026.
For comparison, the parent’s 9.625% notes due 2032 are unsecured, rated B1 / B, and traded at a 14.21% yield on 11 November 2026 (FINRA TRACE, one trade at 82.50).
What CoreWeave’s debt costs overall
By our newsroom’s arithmetic from the 10-Q, CoreWeave’s debt other than convertible notes carried about 9.9% at 30 June 2026, and about 8.4% with the convertibles, on $35,551 million of principal. The dearest line was DDTL 1.0 at 15% (our report). The company’s own measure at 30 September was 7.9%; it did not give its method.
Its debt stood at $46,873 million at 30 September 2026: $41,600 million recourse and $5,273 million non-recourse (newsroom sum of the Q3 balance sheet). On the 10 November call, the CFO guided the next investment-grade DDTL to “a 7% to 7.5% yield based on current SOFR”, and the company said it will not use the unsecured market at current yields (our report). Bloomberg reported on 11 November that it plans an investment-grade loan of at least $4 billion; the terms were not filed.

What to look for in any AI cloud filing
Four questions sort any AI cloud loan. Which entity borrows: the parent or a subsidiary? What is pledged: servers, shares of the SPV, the contract? Who guarantees it: nobody beyond the SPV (non-recourse), or the parent? And which customer’s payments repay it, for how long, compared with the loan’s term? The answers usually explain the rating and the spread.
FAQ
What is an SPV in AI cloud financing?
A separate subsidiary set up to own specific servers and the customer contract that uses them. CoreWeave’s 10-Q describes “bankruptcy-remote, special-purpose consolidated subsidiaries” whose assets “may be used only to settle the obligations of those entities”. Its SPVs held $20.8 billion of pledged assets at 30 June 2026.
How can a high-yield company have an investment-grade loan?
Because the loan is rated on the SPV, not the company. CoreWeave’s DDTL 4.0 is rated A3 because its lenders hold the servers and a customer contract and have no claim on the parent; the parent’s own notes are rated B1.
Does a parent guarantee make a loan safer?
Not if the parent is high yield. CoreWeave’s DDTL 5.5 is guaranteed by the parent but was rated Ba2 / BB+ and priced at SOFR + 5.50%, against SOFR + 2.25% for the non-recourse, A3-rated DDTL 4.0. Its shorter customer contracts left renewal risk.
What is the difference between a coupon and a yield?
The coupon is the fixed rate the company pays on a note; the yield is what a buyer earns at today’s price. CoreWeave’s 2032 notes pay 9.625% but traded at a 14.21% yield on 11 November 2026, at a price of 82.50.
Why do AI clouds also sell convertible notes?
Convertibles pay a low coupon because holders can swap them for shares. CoreWeave’s pay 1.75% and 2.875%. The cost shows up elsewhere: Nebius’s convertibles carry a 1.9% weighted coupon but a 5.1% effective rate, because they accrete to a higher principal.
What happens to the servers when the contract ends?
For the long-term facilities, CoreWeave says “by the time the customer contract ends, the debt is repaid, and the infrastructure is owned free and clear by CoreWeave”. Where the contracts are shorter than the loan, as with DDTL 5.5, lenders take what CoreWeave’s release calls “renewal risk”.
