The six biggest tech companies are now borrowing so much money that they’re competing with the US government for investors’ attention.

JPMorgan strategist Michael Cembalest flagged that hyperscalers, the group that includes Amazon, Alphabet, Meta, Microsoft, Oracle, and Nvidia, have collectively issued roughly $320 billion in new long-term investment-grade debt and related financing through late August 2026. That figure represents approximately 68-70% of total new long-term US Treasury bond issuance over the same period.

Prior to 2025, these same companies issued under $50 billion annually in debt, relying instead on enormous cash piles generated by their core businesses. In 2025, hyperscaler debt issuance climbed to roughly $180-205 billion. By 2026, it nearly doubled again.

The six largest hyperscalers now make up approximately 5% of the US investment-grade bond index, double their share from just two years ago.
