CoreWeave’s borrowing costs came under further pressure on October 15, as its 2031 bonds’ yield rose to 15.78% and five-year credit default swap (CDS) spreads briefly exceeded 1,140 basis points. The spread was last quoted at 1,088 basis points, up 33% in a week and 177% from a year earlier—a level markets commonly associate with distressed credit.
The AI infrastructure provider, part of a group often called “neocloud” companies, has taken on more than $51 billion in debt and related obligations to build data centers, buy chips and expand computing capacity. Its shares and bonds are both under pressure as investors scrutinize the scale of AI investment and how it is financed, making CoreWeave a closely watched test of debt risk in the sector.
Bond yield reaches 15.78% as CDS spreads top 1,000 basis points
Bond yields move in the opposite direction to prices. The rising yield on CoreWeave’s 2031 notes indicates that investors are demanding a higher return to hold the debt. A CDS is a contract that provides protection against a borrower failing to repay; wider spreads generally signal that the market sees greater default risk.
Gavan Nolan, executive director of fixed-income pricing at S&P Global Market Intelligence, said CDS spreads of 1,000 basis points or more are typically viewed as a sign of credit distress. He said the market is not questioning whether demand for CoreWeave’s services exists: the company has contracts with major cloud providers. The key issue is whether those agreements will generate enough cash flow to fund capital spending and service debt.
CoreWeave’s free cash flow is currently deeply negative, Nolan said. The company will need to convert future cash flows into results to demonstrate that its large investments are financially sustainable. Evercore ISI’s trading desk said the market is rejecting AI debt financing that lacks support from operating cash flow.
Sell-off spreads to CoreWeave peers and chipmakers
Credit-market stress has also reached equities. CoreWeave shares fell again on October 15, after dropping 15.5% the previous day. Nebius declined about 5% on October 15, while Iren fell 8%, as other neocloud companies also faced selling pressure.
Concerns about AI spending have extended to chipmakers. Micron Technology shares fell 4% and Advanced Micro Devices lost 6%, following a sharp sell-off in South Korean chip stocks. Investors are looking beyond chip demand itself to the financing costs and repayment burdens companies incur to buy chips, build data centers and lease computing capacity.
CEO says backlog is large enough to cover obligations
In an internal memo, CoreWeave CEO Mike Intrator said periodic misunderstandings about emerging technology companies can lead to irrational moves in share and bond prices. He said the company is confident in its backlog and that existing orders are sufficient to cover all its debt obligations.
CoreWeave’s backlog exceeds $100 billion, with about two-thirds coming from investment-grade counterparties including Microsoft, Meta, IBM and Caterpillar. Deutsche Bank maintained its “buy” rating on the shares, describing the recent market dislocation as an investment opportunity. That view has not eased bond investors’ focus on cash flow and capital spending.
Oracle CDS spreads also widen
Investors’ concerns could extend to other AI-related companies reliant on heavy investment. Oracle’s five-year CDS spread also climbed sharply this week, reaching about 288 basis points, up more than 12% over the week.
Jim Reid, a macro and thematic researcher, said the concerns could become self-reinforcing and create financing pressure for other AI companies. He also noted that a downgrade of Oracle from its current BBB rating could prompt institutions that invest only in investment-grade bonds to sell. The central question for markets remains whether demand for AI infrastructure can translate into operating cash flow quickly enough to support rising debt and capital expenditure.
