Bond market alarm lifted? Strategists assert that the widening credit spreads of AI tech giants are a "supply shock," not a signal of default.

The competition to build artificial intelligence infrastructure has become a core axis of the credit market, driving the scale of debt issuance by tech giants to nearly half a trillion dollars this year. This influx of new bonds currently accounts for about one-third of the total corporate bond supply. Gina Martin Adams, Chief Market Strategist at HB Wealth, stated that this unprecedented wave of AI-related debt has widened the credit spreads and credit default swaps (CDS) for these tech giants, raising concerns about debt-driven risks. As investors grow increasingly anxious about the sustainability of so-called revolving financing and the large balance sheet commitments linked to AI infrastructure construction, NVIDIA Corporation's CDS spreads widened this week, breaking above the peak seen in late July. However, Adams emphasized that this is largely a technical supply issue rather than a deterioration in fundamental financial conditions. A review of the option-adjusted spreads (OAS) for the period from January 2024 to August 2026 confirms this dynamic. While the broader Investment Grade Index held steady at 78.0 basis points as of mid-August 2026, high-quality issuers like Microsoft Corporation (MSFT.US) at 19.6 basis points and Apple Inc. (AAPL.US) at 18.8 basis points maintained extremely tight spreads. In contrast, Meta (META.US) at 103.2 basis points and Oracle Corporation (ORCL.US) at 194.8 basis points stand out, with trading spreads significantly higher than the Investment Grade Index. Adams noted that these two companies are among the only ones in the group with substantial net debt-to-equity ratios. The vast majority of tech giants, supported by large cash balances, still maintain excellent AA ratings, making this entire situation seem more like a slight repricing rather than a major default crisis.
