CoreWeave seeks insurer capital

Highlights

CoreWeave seeks broader investment-grade recognition for chip-backed loans to unlock insurer capital, aiming to expand its AI cloud infrastructure funding base.
CoreWeave raised over $35bn in 2024 via chip-backed loans and other instruments, leading to $52bn in debt and lease obligations by end of June as it targets 8GW capacity by 2030.
Interest costs more than doubled year on year to $640mn in Q2, with S&P highlighting aggressive leverage at 5.8x annualised Q2 EBITDA and ongoing negative free cash flow forecasts.

Debt strategy expands with insurance focus

As reported by Financial Times, CoreWeave is trying to win broader investment-grade treatment for its chip-backed borrowings and eventually for the company itself, a move it believes would open the door to insurer money on a much larger scale. Brannin McBee, the co-founder leading financing efforts, said that access could materially widen the company’s funding base as it scales its AI cloud infrastructure.

CoreWeave has become one of the best-known neocloud providers, operating large clusters of Nvidia chips and renting computing capacity to AI labs and major technology groups. Earlier this year it secured an $8.5bn loan backed by chips and a long-term Meta contract, the first of its chip-backed loans to be fully rated investment grade.

McBee said the next step is persuading insurers to buy loans tied to lower-rated customers such as AI labs, although he acknowledged that market is not yet ready. He added that planned stock market listings by large AI labs could help broaden acceptance of that debt among insurance investors.

Over the past four years, CoreWeave has transformed from a small crypto miner into an AI cloud provider with more than 1.5 gigawatts of active power, with plans to reach 8GW by the end of 2030. To fund that expansion, the company has raised more than $35bn this year through chip-backed loans, high-yield bonds, convertible bonds and share sales, leaving debt and lease obligations at about $52bn at the end of June.

Growth ambitions raise funding and market risks

CoreWeave’s financing model has helped create a new market for loans secured against Nvidia graphics processing units and long-term customer contracts. McBee, a former natural gas and electricity trader, arranged the company’s first such deal in 2023, a $2.3bn loan led by Blackstone, and CoreWeave has since completed five more at lower rates for roughly $27bn in total.

Still, the company’s rapid borrowing has increased scrutiny of its balance sheet. Interest costs more than doubled year on year to $640mn in the second quarter, while S&P describes CoreWeave’s financial risk as aggressive; its debt stood at about 5.8 times annualised second-quarter EBITDA.

Jordan Chalfin, a credit analyst at CreditSights, said CoreWeave had been creative in its financing approach but warned that borrowing costs could rise as rivals and hyperscalers pursue similar chip-backed structures. He also pointed to investor concerns over a mismatch between long data centre leases and shorter customer contracts, especially if the sector overbuilds capacity.

McBee said CoreWeave could reach investment grade within a few years despite forecasts for negative free cash flow over the next several years. He argued the company would be strongly cash-flow positive if it stopped expanding now, but said scale remains critical in the current AI infrastructure race.

CoreWeave is also evaluating a $500bn financing programme Nvidia unveiled with institutional partners including Goldman Sachs in August. McBee said the company expects to help shape that programme, reflecting a deep relationship with Nvidia that includes more than $2bn of investment, a $6.3bn agreement for unused computing capacity and support around CoreWeave’s IPO.

He rejected claims of circular financing and said Nvidia’s contributions account for only a small portion of the tens of billions CoreWeave has raised. McBee also said demand remains strong, with nearly all of the company’s 2027 capacity sold and new contracts now being signed for 2028 and later, while powered-shell data centres remain especially scarce.

Our earlier report on a CoreWeave-linked data center financing explained how a 15-year triple-net lease underpins cash-flow visibility for DDC 01 Propco LLC, which received a BB- rating with a Positive Outlook for its senior secured notes. We noted that construction and delay risks were mitigated by features such as a guaranteed maximum price contract, pre-commencement rent, and a debt service reserve, while the overall rating remained constrained by CoreWeave’s own credit profile.
