AI Debt Issuance Soars Amidst Declining Investor Demand

The artificial intelligence boom is increasingly financed by debt, with major technology companies, known as hyperscalers, significantly increasing their bond issuances. Since the beginning of 2025, Alphabet, Meta, Amazon, and Oracle have collectively issued over $300 billion in bonds, according to Bloomberg calculations. This trend is driven by the immense capital requirements for AI infrastructure, which necessitate funding beyond cash flows and equity offerings. Nvidia, a key player in AI chips, also issued $25 billion in bonds last month, its first such sale in five years. SpaceX, which has entered the AI sector through its acquisition of xAI, sold $25 billion in bonds shortly after a record $86 billion stock offering.

The demand for AI-related capital is projected to continue its upward trajectory. The top five hyperscalers are expected to issue approximately $300 billion annually in the coming years, an increase from $175 billion in 2026. JPMorgan estimates that debt proceeds from these companies, excluding SpaceX, will reach $375 billion between 2026 and 2030. This substantial increase in debt supply coincides with a noticeable decline in investor enthusiasm.

Evidence of this waning demand is emerging. Amazon, for instance, had to offer an additional 18 to 21 basis points of yield on its longest-dated debt during a recent $25 billion bond sale to attract investors. The order book for this sale reached only 2.5 times the amount of bonds offered, a decrease from 3.2 times in March. Bank of America noted in a statement that "Investors are pushing back," suggesting that this situation "should also inject even more uncertainty into the hyperscaler/AI supply outlook."

Further underscoring this trend, Torsten Slok, chief economist at Apollo Global, highlighted a significant drop in the "cover ratio" for hyperscalers, which measures investor orders against the value of bonds offered. This ratio fell from nearly 5x in February 2026 to below 2x in July. Slok warned that this decline indicates "investors may need wider spreads to absorb additional hyperscaler supply," signaling a potential challenge for future debt financing in the AI sector.
