Fears that companies may be borrowing heavily to build AI infrastructure before earning enough to support the investment sent investors looking for more credit protection.

Why AI debt worries drove more CDS trading
A credit default swap, or CDS, is a contract that offers protection if a borrower fails to meet its debt obligations. Buyers pay a premium for that protection; a wider CDS spread means it costs more. 2
The contracts linked to Oracle, SpaceX, Alphabet, Amazon, Meta, Broadcom and Nvidia averaged more than $9 billion in weekly trading in September, compared with less than $2 billion in July, according to figures attributed to Morgan Stanley Research. That is an increase of more than 4.5 times. 17

The move came as AI-related borrowing also grew. One report citing Morgan Stanley put borrowing at an estimated $466 billion so far in 2026, compared with $101 billion over the same period in 2025. The reported purpose was to fund infrastructure such as data centers and chips. 20
The concern was not simply whether AI-related stocks had risen too far. It was whether future revenues would justify the cost of building out computing capacity, and whether borrowers could manage their financing if expected returns failed to arrive. That risk was particularly visible in data-center businesses dependent on future demand. 1

CoreWeave became the clearest credit-stress case
CoreWeave’s five-year CDS spread rose above 1,140 basis points at one point on October 15, according to CNBC. 7 Bloomberg reported a separate intraday high of 1,194.5 basis points and said the pricing implied a greater-than-60% chance of default over five years. These are reported market readings and model-based estimates, not a prediction that a default will occur.
The cost of protection rose alongside pressure in CoreWeave’s bonds. By October 19, its 9.625% bond due in 2032 had a yield to maturity of about 14.9%, near its high of more than 15% the previous week. 6
Oracle also saw a sharp repricing: Reuters reported that its five-year CDS spread widened by 26 basis points overnight to a record 288 basis points on October 15. 2 The evidence here does not establish comparable figures for every company in the seven-issuer trading group, so the aggregate volume increase should not be read as identical stress across all of them.
What the gap between stocks and credit showed
On October 19, AI stocks rebounded after a sharp selloff, but credit-market concerns persisted. CoreWeave shares were up 2.4% in choppy trading after losing about a quarter of their value the previous week; its bond yield remained near 15%, while its CDS remained at distressed levels. 6
That divergence matters because stock prices and credit protection reflect different risks. An equity rebound can indicate renewed appetite for shares, while elevated bond yields and CDS spreads show that lenders and credit investors still see substantial uncertainty about a borrower’s ability to meet its obligations. 6
What the CDS surge does—and does not—say
The sharp increase in trading and protection costs is evidence of greater hedging activity and a repricing of credit risk around the AI build-out. It does not, by itself, prove that the AI sector as a whole is facing imminent defaults. Reuters reported on October 15 that the companies whose CDS had recently risen had not defaulted on their obligations.
Higher perceived risk can create a potential feedback loop: investors may sell a borrower’s bonds, pushing yields and future borrowing costs higher, which can further weaken confidence. But that is a possible transmission mechanism—not proof that it has happened across the sector. 1
2
The clearest conclusion is narrower: as AI-related borrowing expanded, demand for CDS protection increased sharply, and CoreWeave’s credit markets showed acute stress. The broader trading surge is a warning to watch financing risk, not a verdict that every large technology company is in danger of default. 17
