A surge in corporate spending on AI, capex, and M&A can boost stock prices. However, this same activity often requires issuing large amounts of new debt, increasing supply and causing credit spreads to widen, leading to underperformance versus equities.

Massive AI and cloud infrastructure spending by tech giants is flooding the market with new debt. For the first time since the 2008 crisis, this oversupply, not macroeconomic fears, is becoming a primary driver of market volatility and repricing risk for existing corporate bonds.
A massive U.S. capital expenditure cycle for AI and hyperscalers is driving heavy issuance in the U.S. high-grade bond market. This increased supply can crowd out investor demand for emerging market investment-grade credit, creating a notable headwind by potentially pushing up DM spreads.
Morgan Stanley predicts the AI investment cycle, plus M&A and capex, will drive a 60% surge in U.S. investment-grade bond issuance in 2026. This massive supply increase is expected to push U.S. credit spreads wider, even if the underlying economy remains healthy and demand is strong.
Trillion-dollar tech companies are issuing massive bonds to fund AI CapEx, attracting immense demand from yield-hungry institutions. This 'hoovers' up available capital, making it harder and more expensive for smaller, middle-market businesses to secure financing and deepening the K-shaped economic divide.
Tech giants are issuing massive amounts of highly-rated debt at a discount to fund AI expansion. This makes existing, lower-rated corporate bonds from other sectors look less attractive by comparison, forcing a repricing of risk and higher borrowing costs across the credit spectrum.
Despite forecasting a massive surge in bond issuance to fund AI and M&A, Morgan Stanley expects credit spreads to widen only modestly. This is because high-quality, highly-rated companies will lead the issuance, and continued demand from yield-focused buyers should help anchor spreads.
Instead of an imminent collapse, the credit market is likely poised for a final surge in risk-taking. A combination of AI enthusiasm, Fed easing, and fiscal spending will probably drive markets higher and fuel more corporate debt issuance. This growth in leverage will sow the seeds for the eventual downturn.
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.
Barclays forecasts a 40% jump in net investment-grade debt supply in 2026, driven by tech sector CapEx and renewed M&A activity. This massive influx of new bonds will test market demand and could lead to wider credit spreads, even if economic fundamentals remain stable.
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.
