Amazon, Alphabet, Meta, Microsoft, and Oracle have issued roughly $194 billion in bonds already this year, squeezing the same pool of capital that funds US government debt
The bond market has a crowding problem. AI’s biggest spenders are tapping public debt markets at a pace that hasn’t been seen before, and they’re doing it at exactly the moment the US government needs to borrow roughly $2 trillion to cover its own deficit.
Amazon, Alphabet, Meta, Microsoft, and Oracle collectively issued approximately $194 billion in bonds by early July 2026. That figure already surpasses the $108 billion those same companies issued across all of 2025, a 79% increase in about half the time.
The numbers behind the borrowing surge #
Goldman Sachs projects the group will close out 2026 with roughly $250 billion in total issuance, then push that figure to around $400 billion in 2027.
The driver is data centers. Every major AI model requires massive compute infrastructure, and building that infrastructure at scale costs money that even trillion-dollar companies prefer to borrow rather than pull entirely from cash reserves.
On the government side, the US federal budget deficit for the current fiscal year is projected to come in near $2 trillion. Treasury has to sell bonds to finance that gap, and it’s doing so into the same market where hyperscalers are rapidly expanding their own issuance calendars.
Investors are already showing fatigue #
The strain is showing up in the data. Cover ratios fell from nearly 5x in February 2026 to below 2x by July. A ratio above 2x is generally considered healthy; below that threshold, sellers are doing a lot more work to move paper.
Median new-issue concessions jumped from 2.25 basis points in 2025 to 12 basis points in 2026.
Credit spreads over Treasuries have widened too. For shorter-dated hyperscaler bonds in the two-to-four year range, spreads moved from roughly 30 basis points to 40 basis points. Longer-dated paper, bonds with maturities beyond 20 years, saw spreads widen from around 108.5 basis points to 118 basis points.
The Fed is no longer the buyer of last resort #
The Federal Reserve has stepped back from the quantitative easing posture it maintained for much of the post-2008 period. That means the central bank is no longer quietly absorbing excess supply in the Treasury market.
Private-sector investors now have to absorb two overlapping supply waves simultaneously: the projected $2 trillion in annual Treasury issuance and a corporate bond calendar from hyperscalers alone that could hit $400 billion by next year. Without a central bank backstop, price discovery becomes the mechanism, and price discovery with this much supply tends to push yields higher.
What fixed-income investors are watching most closely now is whether the softening in cover ratios stabilizes or continues to deteriorate. A sustained drop below 2x, particularly for longer-dated maturities, would likely force more meaningful repricing across the investment-grade corporate bond market.
