AI debt nerves trigger race for default insurance in case boom turns to bust

By the Editorial Team · Wednesday, October 21, 2026

Investors have sharply increased trading of credit default swaps to hedge against risks from the rapid rise in AI-focused company debt, with weekly volumes hitting over $9 billion in September. This surge reflects growing concern about the sustainability of heavy borrowing by AI firms and signals heightened caution across both speculative and established tech companies.

Investors are increasingly turning to credit default swaps (CDS) to protect their portfolios against potential risks stemming from the rapid expansion of artificial intelligence (AI) infrastructure spending. Trading volumes of these insurance-like derivatives, which provide payouts if the issuer of the underlying debt defaults, have surged sharply in recent months.

According to recent analysis, average weekly trading of CDS linked to bonds from major technology and AI-related companies such as Oracle, SpaceX, Alphabet, Amazon, Meta, Broadcom, and Nvidia reached over $9 billion in September. This marks a significant increase from less than $2 billion in July. Additionally, trading volumes for U.S. corporate CDS indices in 2026 have already exceeded last year’s total, reflecting heightened market activity.

The surge in demand is closely tied to a sharp rise in debt issuance by AI-focused firms. These companies have collectively raised approximately $466 billion this year, substantially higher than the $101 billion raised during the same period in 2025, primarily to fund infrastructure projects including data centers and chip manufacturing.

Investor concern over the scale of borrowing and the ability of these companies to generate sufficient profits from their AI investments has driven up the cost to insure this debt, known as the CDS spread, which hit record highs for certain companies. While spreads have widened for more speculative firms such as AI cloud-computing provider CoreWeave, they have also increased for established players including Microsoft, Alphabet, Amazon, and Meta. For example, the five-year CDS spread for Meta climbed to 108 basis points in October, implying an annual cost of $108,000 to insure $10 million of debt, while Nvidia’s spread rose to 101 basis points. In contrast, CoreWeave’s CDS spread reached approximately 1,090 basis points, with buyers facing substantial upfront payments.

Market strategists describe CDS trading as a key indicator of investor sentiment regarding hyperscaler financing and the broader AI sector. According to some analysts, the market’s primary focus is increasingly divided between these derivatives and companies’ free cash flow positions. The concentrated risk within the AI space incentivizes many investors to purchase CDS as a hedge against potential fallout if the AI boom slows or reverses.

Traditionally, CDS were used mainly by dedicated credit investors. However, there is now growing participation from multi-asset and equity managers who seek a relatively inexpensive way to hedge their exposure to the technology sector. This influx of diverse investors reflects broad unease about the level and concentration of AI-linked debt.

The interconnectedness of AI companies and their suppliers, including infrastructure providers linked to organizations such as OpenAI and Anthropic, has further heightened concerns around systemic risk and bubbles in the sector. Despite the rise in CDS costs for major tech firms, these remain low relative to those deemed more vulnerable, underscoring a differentiated risk perception across the industry.
