Major AI hyperscalers are poised to fuel a significant increase in U.S. corporate bond issuance in 2026, with analysts forecasting $2.46 trillion in total supply. The Big Five tech giants—Amazon, Alphabet, Meta, Microsoft, and Oracle—issued $121 billion in bonds last year and are expected to borrow $140 billion annually over the next three years as they race to expand AI infrastructure.

AI Hyperscalers Reshape Corporate Bond Landscape

U.S. corporate bond supply is heading for a dramatic expansion in 2026, with AI hyperscalers emerging as the primary catalyst behind this financial shift. According to a Barclays report, overall U.S. corporate bond issuance is expected to reach $2.46 trillion in 2026, marking an 11.8% increase from $2.2 trillion in 2025

Surge in Borrowing by Hyperscalers Accelerates

The five major AI hyperscalers—Amazon, Alphabet's Google, Meta, Microsoft, and Oracle—have ramped up their borrowing at an unprecedented pace. These tech giants issued $121 billion in U.S. corporate bonds last year, a staggering increase from an average of $28 billion per year between 2020 and 2024, according to BofA Securities

. BofA analysts project the Big Five hyperscalers will borrow roughly $140 billion annually over the next three years, with potential to exceed $300 billion annually

3

. This anticipated ramp-up would put them on pace with the Big Six banks' expected average $157 billion issuance annually.

Substantial Capital Expenditure Fuels AI Infrastructure Build-Out

Barclays analysts noted that "the increase in net supply is largely a non-financial story, and the biggest upside risk is AI hyperscaler capex, which could require more jumbo public deals than typical"

. AI companies have rapidly increased their spending and borrowing as they race to expand data centers and processors. Hyperscalers made up four of the five biggest U.S. high-grade bond deals in 2025, with most transactions occurring in the second half of the year. Oracle sold $18 billion in bonds in September, followed by Meta's record-breaking $30 billion deal in October—the largest-ever individual non-M&A high-grade bond sale—and November deals from Alphabet ($17.5 billion) and Amazon ($15 billion)

Investment-Grade Bond Market Faces New Dynamics

BofA analysts predict that "more supply to fund AI could make the five hyperscalers some of the largest issuers in the IG index"

3

. This significant increase in U.S. corporate bond issuance signals a fundamental shift in the investment-grade index composition, with tech companies potentially rivaling traditional financial institutions as dominant issuers. The hyperscaler borrowing surge has already widened credit spreads, prompting investors to increasingly turn to credit default swaps (CDS) to hedge against AI-related financial risks

Rising Concerns Over AI-Related Financial Risks

The cost to insure hyperscaler debt through credit default swaps has risen since June 2025, most notably for Oracle, whose five-year CDS has more than tripled since its September deal, according to MUFG

1

. This spike reflects growing investor caution about the sustainability of massive AI infrastructure investments. Bondholders sued Oracle on Wednesday, alleging the company failed to disclose it needed to sell significant additional debt to build out its AI infrastructure

3

. As hyperscalers continue their aggressive expansion, market participants should monitor credit spread movements and the potential for additional disclosure-related legal challenges that could impact future borrowing costs and investor confidence in this sector.
