CoreWeave Sees Investment-Grade Chip Debt Expanding Insurer Access

CoreWeave is looking to investment-grade ratings on more chip-backed debt to attract insurer capital, building on a rated facility that had $2.9 billion drawn by June 30.

Brannin McBee, CoreWeave’s co-founder and chief development officer, said broader ratings coverage, and eventually an investment-grade rating for CoreWeave itself, could help insurers play a larger role in financing. The effort continues the company’s push to bring insurers into AI infrastructure financing.

CoreWeave closed an $8.5 billion delayed-draw facility in March. The structure lets the company borrow in stages as qualifying assets and project conditions allow. The facility is secured by computing infrastructure and a customer contract, and carries ratings of A3 from Moody’s and A (low) from DBRS. Insurance investors participated, though their commitments were not disclosed.

The $8.5 billion is the facility’s borrowing capacity, not the amount already borrowed. By June 30, CoreWeave had drawn $2.9 billion: $1.4 billion at floating rates and $1.5 billion at fixed rates.

CoreWeave’s balance sheet listed $35.068 billion in debt carrying value, $16.319 billion in operating lease liabilities and $221 million in finance lease liabilities at June 30. Together, those items totaled $51.608 billion. The company also listed $35.5 billion in estimated future payments on signed leases that had not begun; those payments are separate from liabilities already recorded.

The facility’s ratings apply to that financing and do not establish an investment-grade rating for CoreWeave or its other debt. McBee said loans tied to contracts with non-investment-grade customers, including AI labs, are not ready for the insurance tranche. “I don't think that non-investment-grade offtakes from us are ready to go into the insurance tranche yet. I do think it'll get there.”

Customer contracts are part of the collateral supporting this kind of financing, making renewal demand relevant to lenders. CreditSights analyst Jordan Chalfin warned that an industry overbuild could make customers less likely to renew contracts. For now, the existing facility shows insurer participation in one rated structure, while loans tied to lower-rated customers remain outside the insurance tranche, McBee said.
