Rated GPU debt: how a non-investment-grade sponsor gets to A (low)
Three GPU financings now carry public ratings, two of them investment grade. The sponsors are not investment grade. The ratings come from the structure.
- 01IREN Hardware 3 is rated A by Fitch and A (low) by DBRS. Lambda Compute I is rated A (low) by DBRS. CoreWeave DDTL 5.5 is rated Ba2 by Moody's.
- 02Lambda reached A (low) by isolating the GPUs and two highly rated take-or-pay contracts in one borrower.
- 03DBRS cut the rating by half a notch because the debt service reserve is lighter than the project finance norm.
A public rating changes who can buy a loan. Banks hold less capital against it, insurers can buy it, and it can be sold on. In 2026 the GPU market reached that point: IREN's Hardware 3 financing is rated A by Fitch and A (low) by DBRS, Lambda's Compute I loan is rated A (low) by DBRS, and CoreWeave's DDTL 5.5 is rated Ba2 by Moody's.
None of those sponsors is itself rated investment grade. The ratings attach to the financing, and Lambda Compute I shows how.
How the Lambda structure works
Lambda Compute I LLC, an indirect subsidiary of Lambda, owns more than 30,000 NVIDIA GB300 and VR200 GPUs and leases the capacity to two highly rated customers under take-or-pay contracts. Lenders have step-in rights under those contracts. JPMorgan is sole lead arranger of the US$1.008bn fixed-rate delayed-draw term loan, and Lambda's equity funds part of the build.
Lambda Compute I: what the A (low) rating relies on
What the rating relies on
The DBRS release points to features any project finance lender would recognise:
- Draw conditions tied to delivery and acceptance of the GPUs.
- Amortisation of each tranche once its GPUs stabilise, at a 1.20x minimum DSCR, with final maturity in May 2033.
- Fixed-price supply from Dell for the later tranches, and independent technical review of the data centres' redundancy.
- Operations: a spares plan, warranty terms and power hedging with a reserve for unhedged power.
DBRS also cut the rating by half a notch because the debt service reserve is lighter than the project finance norm. That single adjustment is a useful benchmark: the agencies are measuring GPU deals against infrastructure practice, and pricing the gaps.
Questions for sponsors considering a rating
- Is the customer's credit strong enough, and its contract long enough, to carry the loan to full repayment?
- Which reserves would the agency expect, and what does a lighter reserve cost in notches?
- Can the operational protections, such as spares, warranties and power hedging, be documented as obligations?
- Would a rating widen the investor base enough to justify the cost and disclosure?
