Global Bond Sales Reach $6.61 Trillion Record on Tech AI Borrowing

World debt issuance hit a fresh annual peak as a surge in capital spending on artificial intelligence drove companies to raise unprecedented levels of credit. The total volume of bond sales reached $6.61 trillion, a milestone that mirrored a spike in US investment-grade debt, which climbed to $1.76 trillion to exceed the pandemic-era high of $1.75 trillion set in 2020.

The borrowing trend has been led by hyperscalers including Amazon, Meta, Alphabet and Oracle, which together issued more than $228 billion in bonds—nearly 14 times the $16.7 billion those four firms raised in 2024. BlackRock’s Rick Rieder said the scale of recent financing in debt and equity markets is without precedent, while Bank of America predicts the momentum will continue with a record $175 billion in US investment-grade issuance during November.

Orderly AI Financing
Record global bond issuance is treated as evidence of deep demand for long-dated, investment-grade technology credit rather than a late-cycle warning. Large AI infrastructure borrowers continue to fund data centers and chips without a sharp rise in required yields.

Leverage Questions Intensify
Investors begin to differentiate between cash-rich hyperscalers and companies relying more heavily on debt to fund AI buildouts. The market does not shut, but spreads widen for borrowers seen as carrying greater execution risk.

Issuance Repricing Phase
The record issuance pace leaves dealers and investors temporarily saturated. Borrowers still have access to funding, but the market demands better pricing and a slower calendar after the AI-driven surge.

Policy Scrutiny Rises
Regulators and lawmakers focus on whether AI data-center borrowing is creating concentrated credit, power-grid and disclosure risks. The reaction is mostly sector-specific because no immediate funding failure or systemic bank exposure is evident.
