Big Tech bond demand collapsed to 1.7x cover ratio in July, lowest since Sept 2025, as investors cool on AI capex financing.
Macro & Markets ·
Investor appetite for debt issued by major technology firms has weakened considerably. The cover ratio for bonds from Amazon, Apple, Meta, Microsoft, and Oracle fell to approximately 1.7x in July, marking the lowest level since at least September 2025, according to market data. This metric—which reflects the dollar volume of investor orders relative to bonds offered—has declined 3.0 points over five months. The current reading stands roughly half the 3.4x average seen across all investment-grade bonds, a sharp reversal from February 2026, when Big Tech's cover ratio reached 4.7x, exceeding the broader market average.
The pullback reflects shifting sentiment around financing for artificial intelligence infrastructure investments. Despite issuing a record $194 billion in debt across currencies year-to-date—equivalent to approximately 9 percent of total U.S. investment-grade bond supply—these major technology firms face notably reduced demand for their borrowing. The compression in cover ratios suggests bond investors are reassessing their exposure to the sector's capital expenditure cycle.
What remains unclear is whether this softening reflects temporary market dynamics or a more sustained repricing of technology debt risk. The extent to which reduced bond demand may constrain technology firms' ability to finance ongoing AI buildout remains to be seen.
