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.

Unlike prior tech revolutions funded mainly by equity, the AI infrastructure build-out is increasingly reliant on debt. This blurs the line between speculative growth capital (equity) and financing for predictable cash flows (debt), magnifying potential losses and increasing systemic failure risk if the AI boom falters.

Private credit funds are exposed on two fronts: they are financing the massive debt rounds for AI infrastructure and also hold debt for traditional SaaS companies. As AI companies pitch a future where they render SaaS obsolete, it creates instability and default risk across these private credit portfolios.

While equity markets remain bullish on mega-cap tech, the bond market is flashing a warning. The credit spreads for hyperscalers are widening as they take on massive debt for AI capex. This signals that debt investors, who are often more risk-aware, see growing financial strain that equity investors are ignoring.

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.

While AI growth seems organic, low interest rates encourage even healthy companies to take on excessive debt. This is happening now, with some AI-related firms seeing decreasing free cash flow as leverage increases. The private credit market is already showing signs of nervousness about this trend.

While MAG7 companies fund AI spending with cash flow, the real danger is other firms using debt, especially private credit. This transforms potential corporate failures from isolated events into systemic risks that can cause broader economic ripple effects.

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.

Major tech companies are financing their AI build-outs so aggressively that they are undeterred by rising debt costs. This inelastic demand for capital could drive up borrowing costs across the entire corporate bond market, creating a 'crowding out' effect that impacts companies in unrelated sectors.
