CoreWeave wants investment-grade ratings to tap 'unlimited' insurance money for its AI build-out
What's going on? CoreWeave co-founder Brannin McBee, who runs the neocloud's financing, told the Financial Times the company wants investment-grade ratings on more of its chip-backed debt, and eventually on CoreWeave itself, so it can reach insurance-company capital. That pool "is unlimited… all the money in the world that sits in the insurance tranche," he said.
The template: Earlier this year CoreWeave closed an $8.5bn loan secured on its chips and backed by an offtake contract with Meta, the first chip-backed loan to be fully rated investment grade. The structure goes back to 2023, when a $2.3bn Blackstone-led loan was secured on Nvidia GPUs and backed by a Microsoft contract, at an effective rate of about 15%. The chips sit in subsidiaries, contract revenue pays interest, principal and costs first, and roughly 20 cents of each dollar reaches the parent. Five similar loans since then add up to about $27bn. Contracts with AI labs, which are not investment grade, are "not ready" for the insurance tranche yet, McBee said, though he expects them to get there, helped by lab IPOs.
By the numbers: CoreWeave has raised more than $35bn this year across chip-backed loans, high-yield bonds, convertibles and share sales, and had about $52bn of debt and lease obligations at the end of June. Second-quarter interest costs more than doubled to $640mn, and debt is about 5.8 times annualised Q2 EBITDA. Visible Alpha consensus puts free cash flow at about -$25bn this year, -$28bn next year and -$18bn in 2028. Active power is above 1.5GW, with a plan for 8GW by the end of 2030. Nearly all 2027 capacity is sold and the company is signing contracts for 2028 and beyond. "If you gave me 100 megs of powered shell today, I'd sell it in 18 seconds," McBee said.
Why it matters: Neoclouds are trying to turn GPU capacity contracts into bond-like assets that insurers and other long-term investors can hold. If that works, the AI build-out gets access to a far larger pool of money than venture capital, high-yield bonds or bank loans.
The risks: S&P rates CoreWeave's financial risk as "aggressive". Jordan Chalfin of CreditSightsDealroom has a profile for this one. Try Dealroom → calls the structures "very creative" but warns that costs could rise (CoreWeave's unsecured bonds yield almost 15%) and points to a mismatch between long data-centre leases and shorter customer contracts: "If there's an overbuild, why would [customers] renew?" McBee rejects the idea of circular financing with Nvidia, which has invested more than $2bn, signed a $6.3bn agreement to buy unused capacity and anchored CoreWeave's IPO. CoreWeave's founders have sold about $2bn of shares this year, according to S&P Capital IQ.
What's not known: Whether rating agencies will grant more investment-grade ratings, and when; what pricing insurers would demand; and whether CoreWeave will use Nvidia's $500bn financing programme, which it says it is "actively" looking at. The insurance-tranche ambition is McBee's stated goal, not a completed deal.
