CoreWeave, the "Eye of the Storm" in the Latest AI Crash amid "Double Blow to Stocks and Bonds"

This infrastructure company focused on AI cloud computing is becoming the most concentrated reflection of the risk accumulation in the current wave of artificial intelligence investment frenzy.

This week, CoreWeave’s share price plunged 25% in a single week, marking its worst performance since November 2025; meanwhile, its junk-rated bond yield soared to 15%, a level typically considered a critical indicator of debt distress, and credit default swap pricing shows its five-year default probability exceeds 60%.

Despite Nvidia CEO Jensen Huang publicly expressing confidence in CoreWeave on Thursday, and Deutsche Bank characterizing the sell-off as a "buying opportunity"—with the stock rebounding 5.9% that day—market unease has not dissipated. On Friday, CoreWeave’s share price fell another 12%, closing the week down 25% overall.

The turbulence triggered by this “double whammy” in both stocks and bonds has spread outward: The Philadelphia Semiconductor Index dropped 11% this week, about 24% down from its June 2025 peak; the Nasdaq 100 Index recorded its worst single-week performance since April 2025, falling 5.5%; the average yield of high-yield bonds climbed to 8.41% on Wednesday, an 18-month high, while risk spreads widened to their broadest level since March.

During this bout of volatility, trends in the bond market have been seen by some market participants as having deeper significance than share prices themselves.

Bonds issued by CoreWeave in June 2025 with a yield of 9.675% saw their yields surge to 15% this week, reaching levels typically recognized as “distressed.” At the same time, the cost of debt default protection rose to record highs on Thursday.

Max Frumes, head of financing at credit data and analytics firm 9fin, stated:

CoreWeave is absolutely the ‘canary in the coal mine’ for this sector. This will become a turning point in how credit for the AI frenzy is priced, accessed, and structured. Pricing will rise, scrutiny will increase, and we may see a marked backlash from investors.

Jim Reid, Deutsche Bank’s Global Head of Macro and Thematic Research, pointed out that the market is entering a new phase where the importance of debt financing is rising. He wrote in his latest research report:

As we enter a capex cycle driven by debt rather than free cash flow, we must pay increasing attention to credit price trends. Overall, financing costs for AI are not an issue, but there are worrying signs at the margins.

From a more macro perspective, so far this year the U.S. bond market has issued $106 billion in investment-grade and high-yield bonds for project financing, nearly triple the $37 billion total for all of 2025, with a large portion flowing into AI-related investments such as data centers.

Goldman Sachs strategists estimate that global project financing bond issuance could exceed $300 billion next year.

CoreWeave’s debt distress has clearly transmitted to the entire AI infrastructure financing ecosystem.

According to Bloomberg, bonds tied to data centers such as Tract Capital Management, Prime Data Centers, and Cipher Digital all hit record lows this week. The average dollar price of high-yield data center bonds has dropped from about $101 in June 2025 to around $95.

The Goldman Sachs U.S. AI Data Center Basket Index (GSUCADSP) experienced dramatic surges early this week.

CoreWeave’s co-founder said this week the company is exploring financing in the investment-grade debt market, including tapping the vast pools of insurance capital. This move stoked concerns that the company may take on large-scale debt, further intensifying sell-off pressure.

Grant Nachman, founder and Chief Investment Officer of Shorecliff Asset Management, remarked:

At current market prices, large-scale unsecured new cloud computing company financing is either so expensive as to be prohibitive, or simply impossible to complete, or both.

He believes that in order for new bonds to attract buyers, they may need to be collateralized by assets or contractual cash flows, and offer stronger creditor protection covenants.

On Thursday, JPMorgan Chase and Goldman Sachs increased incentives for investors (sweeteners) in a $5 billion leveraged loan underwritten for AI cloud infrastructure startup Volta Infrastructure Holdings. The final yield on this loan exceeded an initial discussion level of 11%, matching the highest interest rate on record in the AI infrastructure financing space.

Amanda Lynam, Goldman Sachs’s Chief Credit Strategist, had already warned that the surge in U.S. high-yield corporate bond issuance is starting to overwhelm debt investors.

John Yovanovic, co-head of leveraged finance at MetLife Investment Management, zeroed in on the heart of the matter:

The issue isn’t that credit conditions have changed over the past year, but that there’s a massive supply still to come in the next year and a half.

In the equity market, CoreWeave’s high-leverage business model is facing a much harsher re-rating.

Since going public at $40 per share in March 2025, CoreWeave’s share price once soared over 360% on the back of surging AI demand. But this was followed by a severe correction; it has now fallen about 67% from its peak, hovering around $60 and less than $25 above its IPO price.

It’s worth noting that the company’s IPO itself was quite turbulent and required “backstop” support from Nvidia. Optimistic analysts consider the current sell-off an overreaction by the market.

Deutsche Bank analyst Brad Zelnick maintains a Buy rating, highlighting in a Thursday report that CoreWeave has "a strong customer base, proven execution record, order backlog conversion capability, and leading infrastructure performance." He believes the AI compute demand trend continues to outstrip supply, and the core industry fundamentals remain unchanged.

However, a changing macro environment makes it difficult for optimism to fully unfold. Roundhill Financial’s ETF strategist Thomas DiFazio said:

The macro backdrop has created a ‘sell first, ask questions later’ market. It’s hard to say things have improved in the short term.

Bloomberg Intelligence analyst Robert Schiffman pointed out that, in theory, CoreWeave’s close relationship with Nvidia could provide a source of capital if market financing channels narrow. However, Jensen Huang, while in Stockholm, explicitly refuted this possibility, saying:

CoreWeave doesn’t need a bailout. They are getting stronger every day. I’m optimistic. Their capital costs are actually going down.

This wave of turmoil has exposed a clear split in the market’s view on both CoreWeave and the broader logic of AI investment.

The pessimists focus on: rising U.S. treasury yields and persistent inflation driving up financing costs; the long cycle from building AI data centers to generating returns; the risk of GPU equipment becoming obsolete even before new facilities go live; and mounting political controversy over data center permits and electricity pricing.

Larry Holzenthaler, Senior Portfolio Manager at fixed-income house Catalyst Funds, stated:

A few months ago, I would have said people were too optimistic on AI.

He believes that the risks dismissed or downplayed by the market back in June—massive financing needs, high leverage, reliance on external funding—are now being repriced in a much more forceful way.

Optimists, on the other hand, believe the AI capex cycle is still in its early stages, and the long-term demand story remains unshaken.

Matt Bartolini, Global Head of Research Strategy at State Street Global Advisors, said:

We’re still early in the AI capex cycle. Interest rates won’t become an insurmountable hurdle, but they do change the math behind continual debt issuance and whether this funding can match up with credible future growth. The long-term demand story is what drives the capex cycle, and I believe that demand will persist, no matter what happens to rates.

John Han, a portfolio manager at fixed-income firm F/m Investments, said his team is "actively reassessing overall exposure to AI infrastructure, especially where the risks are concentrated and whether we’re being adequately compensated."

At the core of this debate is that AI investors are facing a historic valuation reset: As the era of free money ends, the sustainability of debt-driven AI infrastructure business models is being subjected to unprecedented market scrutiny.
