The primary threat to today's tight credit spreads is not weakening demand but a sustained surge in supply, particularly from AI 'hyperscalers'. The concern is how this new debt is employed, as it could fundamentally deteriorate the issuers' balance sheets over time.

The rapid, unpredictable nature of AI makes corporate futures 'increasingly invisible.' This fundamental uncertainty calls into question all long-term valuations, sparking a debate on whether multiples for all businesses, not just tech, should be structurally lower, regardless of the macroeconomic environment.

Heavy issuance from tech giants is forcing them to sweeten the deal for long-term investors. A hyperscaler that recently issued debt offered a 42 basis point curve between its 10- and 30-year bonds, more than double the 20 basis points from its previous deal.

Unlike equities, credit markets face a growing risk from the AI boom. As companies increasingly use debt instead of cash to finance AI and data center expansion, the rising supply of corporate bonds could pressure credit spreads to widen, even in a strong economy, echoing dynamics from the late 1990s tech bubble.

Unlike M&A financing with a clear deleveraging path, the AI investment cycle represents a permanent use of debt capacity. This unprecedented scale requires investors to re-evaluate long-term credit risk, concentration limits, and ratings for hyperscaler companies.

A significant portion of private credit portfolios consists of loans to software companies, which were underwritten based on predictable, recurring revenue. AI is now fundamentally disrupting these business models, threatening to devalue the very collateral that underpins billions of dollars in these 'safe' loans.

Tech giants are no longer funding AI capital expenditures solely with their massive free cash flow. They are increasingly turning to debt issuance, which fundamentally alters their risk profile. This introduces default risk and requires a repricing of their credit spreads and equity valuations.

A significant portion of private credit is concentrated in software companies. Many of these loans were made when rates were low, often with high leverage and weak terms. The emergent threat of AI-driven disruption to their business models now adds a new layer of fundamental risk to this already vulnerable cohort.

Massive, strategically crucial AI capital expenditures by the world's wealthiest companies could create a new risk. These firms may be less sensitive to borrowing costs, potentially issuing debt even into a weakening market, which could drive credit spreads wider for all issuers.
