Credit markets show strength despite high issuance, fueled by AI optimism

Credit markets are showing unexpected strength, absorbing more than $300 billion in new debt issuance since the beginning of 2026. This robust performance is largely attributed to sustained investor optimism surrounding artificial intelligence (AI), which is driving significant demand for new debt. Credit default swaps and spreads have not indicated any signs of stress, suggesting a healthy market environment despite the high volume of new debt being issued. Investor appetite, particularly for AI-related ventures, is so strong that it is leading to oversubscribed deals and a tightening of credit spreads.

This positive outlook in public credit markets stands in stark contrast to the private credit sector, where borrower defaults have reached a record high. According to a Kroll Bond Rating Agency index, the default rate among private-credit borrowers is at its highest point in the index's three-year history. This indicates increasing financial stress within the $1.8 trillion private credit industry, suggesting that while public markets are thriving on AI narratives, a segment of the private lending landscape is struggling.

Within the AI investment landscape itself, strategies are evolving. Gavin Baker, CIO of Atreides Management, notes a shift in focus from companies addressing supply chain bottlenecks to those possessing enduring franchise value. This suggests investors are looking beyond immediate production challenges and are instead prioritizing companies with sustainable competitive advantages and long-term market positioning.

Further underscoring the strong investor interest in AI-related companies, Nvidia recently completed a substantial $25 billion bond sale. The issuance has experienced robust initial trading volume, indicating active market participation. Despite this high level of activity, the prices of Nvidia's newly issued bonds have remained largely stable, trading close to their original sale price, which reflects continued confidence in the company and its market position.
