AI-linked bond sales hit $220B in 2026, up 62% from last year

Companies have sold roughly $220 billion of AI-linked bonds across currencies so far in 2026, a 62% increase from all of 2025, according to Bank of America ↘ 0.91% data, as technology giants pour unprecedented amounts of capital into artificial intelligence infrastructure.finance.yahoo+1

A Market Transformed by Tech Borrowers

The wave of issuance has been driven by hyperscalers including Amazon Amazon.com, Inc. ↘ 1.87%, Meta ↘ 3.72%, Alphabet ↘ 2.32%, Oracle ↘ 4.64%, and Nvidia ↘ 1.43%, which are tapping bond markets at a pace that has reshaped major credit indexes. Amazon alone set a record in March with a $53.8 billion-equivalent multi-currency bond sale — the largest corporate bond offering in capital markets history — spanning 19 tranches over two days to fund its AI and cloud expansion.reuters+1

The flood of highly rated debt has shifted the composition of the US investment-grade bond index. AA and A rated bonds now account for 52% of Bloomberg's US investment-grade bond index, up from about 46% in 2021, according to a Barclays ↘ 0.09% analysis through the end of June. Credit spreads hit their lowest level since 1998 earlier this year, tightening to just 71 basis points above Treasuries.bloomberg+1

Growing Unease Over Concentration Risk

Yet investors are growing uneasy that this apparent safety could prove fragile. Bloomberg reported on July 2 that many investors fear the improved credit quality "will prove illusory" if AI spending fails to generate the returns companies are projecting. The concern is that a single sector — technology — now dominates index-level credit metrics in a way it never has before.bloomberg

Tech borrowers have displaced banks in several major investment-grade credit indexes, a structural shift driven entirely by AI infrastructure spending. Hyperscalers issued $121 billion in US corporate bonds in 2025 alone, more than four times their 2020-2024 annual average, and 2026 volumes are on pace to shatter that figure.aiweekly+1

The Stakes Ahead

Industry estimates suggest AI-related capital expenditure could approach $600 billion in 2026. If revenue growth from these investments disappoints in the second half of the year, hyperscaler credit spreads could widen sharply, forcing index-benchmarked pension and insurance funds to absorb losses on what they assumed was among the safest corporate debt available.pinebridge+1

"The US corporate bond market is getting safer as more high-rated tech companies sell debt," Bloomberg reported. "Many investors fear that safety will prove illusory."bloomberg
