CoreWeave Closes Landmark $8.5 Billion Financing Facility, Achieving First Investment-Grade Rated GPU-backed Financing (DDTL 4.0)
$8.5bn non-recourse DDTL (about $7.5bn available at first), floating SOFR+2.25% / fixed ~5.9%, matures March 2032, A3 (Moody's) / A (low) (DBRS), secured on a single-purpose subsidiary and one 'leading AI enterprise' contract. First point of the +225 -> +450 -> +550 curve; closed 2026-03-31, so the curve spans ~4.5 months, and its first step lines up with a switch to sub-investment-grade customers.

Lead
On 31 March 2026 CoreWeave closed an $8.5 billion delayed draw term loan ("DDTL 4.0 Facility"). It is rated A3 by Moody's and A (low) by DBRS, which the company calls "the first investment-grade rated financing secured by HPC infrastructure and an associated customer contract". The release describes it as a "first of a kind non-recourse facility".

What it adds to this rung
1. The first point of the curve, and a correction to its dates. The DDTL 5.5 close read listed DDTL 4.0 as a 2025 facility. It is not: it closed on 2026-03-31. So the three facilities span about four and a half months, not about a year:
| Facility | Closed | Size | Pricing | Rating (agencies) |
|---|---|---|---|---|
| DDTL 4.0 | 2026-03-31 | $8.5bn | SOFR + 2.25% / ~5.9% fixed | A3 (Moody's) / A (low) (DBRS) |
| DDTL 5.0 | 2026-05-18 | $3.1bn | SOFR + 4.50% | Ba2 (Moody's) / BB+ (Fitch) |
| DDTL 5.5 | 2026-08-10 | $2.6bn | SOFR + 5.50% | Ba2 (Moody's) / BB+ (Fitch) |
2. The biggest reason for the gap is probably who the customer is, not when the loan was made. DDTL 4.0 is secured by one ring-fenced company holding the assets and a contract with a "leading AI enterprise". DDTL 5.0 says outright that its two customers are below investment grade. A loan is usually rated no better than the customer paying for the chips it finances. So the jump from SOFR + 2.25% to + 4.50% is mostly a change in customer credit, not a market repricing over time. This is an inference from the two releases. Neither release puts a number on how much of the gap is customer credit and how much is timing. Read the curve as "the same borrower pays about 2.25 points more to finance chips for a junk-rated customer than for an investment-grade one", and less as "GPU debt got 3.25 points dearer in a year".
3. The ring-fenced company is the structure itself. CoreWeave Compute Acquisition Co. VIII, LLC is a separate, single-purpose subsidiary. The lenders' claim is on it and its assets, not on CoreWeave as a whole ("non-recourse"). This is the first source on the rung for the special-purpose-vehicle (SPV) structure that the rung's scope names. The Roman numeral VIII suggests at least seven earlier such vehicles [unverified: the release does not say].
4. The company framed this facility as a fall in its cost of capital. The release says "further reducing our cost of capital". That was true when it was issued. The next two facilities priced higher. The words are a snapshot, and the curve is what you get when you read the three releases together.
Through-line: token price → task price
The interest rate on the loan that bought the chip is one of the inputs to the chip's hourly cost, and so to every token served on it. This release gives the cheapest money CoreWeave has disclosed: SOFR + 2.25%, or about 5.9% fixed. Set beside SOFR + 5.50% five months later, it puts a range on the financing part of a GPU-hour's cost. No source here yet converts that range into dollars per GPU-hour.
Limitations
- Issuer press release, not the credit agreement. No advance rate, covenants, amortisation, draw conditions or the value lenders assume for the chips at the end.
- The two ratings come from different agencies. DDTL 4.0 is Moody's and DBRS; DDTL 5.0 and 5.5 are Moody's and Fitch. The Moody's step (A3 to Ba2) is like-for-like; the second agency is not.
- The customer is unnamed. "Leading AI enterprise" is all the release says, so the customer-credit explanation in point 2 cannot be checked from this source.
- The fixed tranche's size is not given, so the blended rate on the whole facility is unknown.
- "First investment-grade" is the company's claim, not checked independently here.
- Vendor bias: this is the borrower describing its own financing. Figures are read as stated, with the as-of date 2026-03-31.
