AI Financing Under Pressure: CoreWeave Bonds at Distressed Levels, IMF Warns of Systemic Risks

Technology stocks came under heavy pressure in mid-October 2026. At the centre of concerns is the worry that numerous companies are funding their multibillion-dollar expansion in artificial intelligence with unsustainable financing models. The Nasdaq 100 fell 2.5 percent on October 16, while semiconductor stocks recorded their eighth consecutive loss period – the longest losing streak since 2008.

CoreWeave as the focal point of credit concerns

Cloud computing provider CoreWeave became a symbol of market fears. The company has taken on several dozen billion US dollars in debt to finance data centers for AI applications. On October 16, CoreWeave stock plummeted 12 percent. The 9-percent bonds issued by the company traded at 80.75 cents per dollar – a price level typically associated with distressed debt securities. The yield on these bonds climbed to 15.3 percent.

CoreWeave exemplifies a financing practice that is increasingly making investors wary: companies accumulate high debt to expand AI infrastructure whose earning power has yet to be proven. The question of whether massive investments will generate sufficient returns is driving the current sell-off.

Broad-based sell-off in the AI sector

The turmoil was not limited to CoreWeave. IREN, Cipher Digital and Applied Digital also suffered double-digit daily losses. Established semiconductor manufacturers were not spared either: US shares of ASML fell 3.9 percent to 1,650 US dollars, even though the Dutch company had raised its revenue guidance for 2026 for the third time. The sell-off engulfed the entire neocloud, data center and semiconductor complex.

The selling pressure results primarily from a reassessment of the financing structures underlying the AI expansion. Rising financing costs are exacerbating the situation: US Treasury yields remain elevated, while inflation proves more stubborn than expected. This further raises borrowing costs and intensifies doubts about the financial sustainability of many AI investments.

International Monetary Fund warns of systemic risks

The International Monetary Fund rated a collapse in AI stocks as a "material risk" to global financial stability in its October 2026 report. The IMF identified equity transactions between large cloud providers and smaller AI firms totalling 300 billion US dollars over the past three years. In addition, there are 650 billion US dollars in debt – coupled with 1.4 trillion US dollars in future revenue commitments. The IMF described these "circular financing arrangements" as potentially problematic.

The concern: Should the lofty expectations for AI revenues not materialise, the mountains of debt could prove unsustainable. Because many companies are financing their expansion through high-yield bonds and loans, a default would send ripple effects through the financial system.

Macroeconomic additional pressures

In parallel with financing concerns, macroeconomic factors are intensifying pressure on tech stocks. A group of US congressmen introduced legislation on October 16 that would block an agreement by President Donald Trump to release Russian diesel onto the world market. Brent crude oil traded around 110 US dollars per barrel. Higher energy costs amplify inflation pressure and burden US Treasuries further.

At market close on October 15, 2026 at 2:00 a.m. CEST, the DAX stood at 25,488.5 points and rose 0.93 percent from the previous day's close. The S&P 500 rose 0.33 percent in the same period to 7,744.06 points, while the Nasdaq Composite closed virtually unchanged with a gain of 0.08 percent at 26,713.03 points. The US indices thus showed greater resilience than the technology-heavy Nasdaq 100, which declined sharply on October 16.

Which companies are particularly at risk

Investors now distinguish more sharply between companies with solid balance sheets and those that rely heavily on debt. CoreWeave is considered an extreme case: the company finances its AI data centers primarily through high-yield bonds whose prices have now fallen to distressed levels. Other smaller AI infrastructure providers such as IREN, Cipher Digital and Applied Digital also came under pressure because their business models are based on high debt-to-capital ratios.

By contrast, established technology companies such as Microsoft, Amazon or Alphabet have substantial cash reserves and can finance their AI investments from operating profits. These differences in capital structure are currently being reassessed by investors.

Recovery on October 16 points to a counter-movement

On October 16, 2026 at around 12:30 p.m. ET, a slight counter-movement appeared. CoreWeave shares traded only around 2 percent lower after falling sharply in the preceding days. Whether this represents a sustained stabilisation or merely a technical counter-movement remains to be seen. Volatility in the AI sector is likely to remain high as long as the question of financing sustainability remains unresolved.
