Four companies are driving most of the fresh corporate bond supply tied to the AI buildout. Amazon.com Inc. (NASDAQ:AMZN), Alphabet Inc. (NASDAQ:GOOG) (NASDAQ:GOOGL), Meta Platforms Inc. (NASDAQ:META) and Oracle Corp. (NYSE:ORCL) sold about $194 billion of bonds in 2026 through early July, up 79% from roughly $108 billion for all of 2025, according to a Reuters analysis of LSEG data.
Goldman Sachs expects issuance from those four plus Microsoft Corp. (NASDAQ:MSFT) to reach $250 billion this year and $400 billion in 2027.
Equity Raises Widen The Tally
The tally widens once equity raises are included. Through July 22, the same five hyperscalers had collectively raised $302 billion via stock and bond sales, Axios reported, citing S&P Global Market Intelligence.
Goldman separately pegged global AI-related debt supply at $489 billion so far this year, already ahead of its full 2025 estimate of $322 billion. Fortune put the bond total alone at more than $300 billion since the start of 2025 for Alphabet, Meta, Amazon and Oracle.
This supply now sits alongside the Treasury’s own borrowing needs rather than off to the side. AI-related debt has climbed to roughly 15% of total investment-grade bond issuance, Barclays data shows, per Reuters.
A separate Reuters piece cited a strategist who put AI-linked issuance at about 15% of the total duration the Treasury supplies to the market.
Apollo chief economist Torsten Slok has warned that the surge raises a basic question: who becomes the marginal buyer of investment-grade paper when hyperscaler supply keeps climbing, Fortune reported.
The federal deficit, meanwhile, is running near $2 trillion a year with roughly $1 trillion in interest costs alone, leaving the Treasury little room to out-yield the competition.
Investors Push Back On Price
Investors are pushing back on price. A Wall Street Journal report on a combined $75 billion of bonds from Nvidia Corp. (NASDAQ:NVDA), SpaceX (NASDAQ:SPCX) and Amazon found the debt struggled to clear the market and slumped soon after pricing.
Spreads on hyperscaler paper have widened across maturities this year, with Amazon needing extra yield to complete a recent $25 billion sale.
The strain has shown up in Treasury’s own market too. The 30-year yield topped 5.33% on Tuesday, a level CNBC linked directly to hyperscaler debt issuance layering onto an already crowded long end of the curve.
