CoreWeave stock selloff tracks rising debt-market fears

The CoreWeave stock selloff deepened during the week of October 12-16, with shares falling nearly 12% on Friday and about a quarter from the previous Friday’s close, according to CNBC. The decline came as CoreWeave bonds weakened and investors reassessed the financing behind the company’s AI-computing expansion, while the Nasdaq lost 4.5% for the week.

The clearest market signal was in credit. Reuters reported that yields on CoreWeave bonds issued in April traded at about 15% on October 15, while the bonds changed hands at 79.15 cents on the dollar, according to Tradeweb data. Bond prices and yields move in opposite directions: when a bond’s price falls, its yield rises because buyers demand a greater prospective return to hold it.

Why did CoreWeave stock sell off?

Investors were reacting to the prospect that CoreWeave may face higher funding costs as it continues to build AI infrastructure with borrowed money. Reuters reported that the company had about $50 billion of debt. Yahoo Finance put the total at roughly $52 billion at the end of June, compared with about $15 billion a year earlier. The differing estimates point to the scale of the borrowing, rather than a single comparable reported figure.

CoreWeave is a so-called neocloud provider, renting computing capacity built around Nvidia processors to AI customers. Reuters reported that such companies often borrow heavily to buy costly chips. The concern in the market was whether future revenue and profitability can support that debt-funded expansion if lenders require materially higher returns.

What does CoreWeave’s CDS pricing mean?

Investors also focused on credit-default swaps, or CDS. A CDS is a contract that can protect a debt holder against losses if an issuer defaults. CNBC reported that five-year CoreWeave CDS rose above 1,000 basis points during the week. At that level, insuring $1 million of CoreWeave debt would cost more than $100,000 a year, CNBC said.

Reuters reported that CDS pricing implied a nearly 63% market-implied chance of default over five years, up from about 30% a year earlier. That figure is derived from traded prices, not a forecast that a default will occur. CDS pricing also differs from a formal credit rating and can change rapidly as investors trade the contracts.

Bond yields incorporate factors beyond company-specific credit risk, including benchmark rates, expected inflation and market liquidity. CNBC said CDS spreads are a more direct measure of the credit risk that investors assign to the issuer. Together, the higher yields and wider CDS spreads indicated that debt investors were demanding more compensation for perceived risk.

There were countervailing signals. Reuters reported that Nvidia chief executive Jensen Huang said CoreWeave’s financial strength was improving and that Nvidia did not need to backstop the company. Reuters also reported an arrangement under which Nvidia would buy unsold CoreWeave capacity through April 13, 2032. Those assurances did not prevent investors from repricing CoreWeave’s shares and debt during the week.
