Corporate Debt Surge Forces Investors To Rethink Bond Strategies
Companies are borrowing much more money than they did last year.
By August 2026, U.S. companies had issued $1.68 trillion in debt.
Big cloud companies that support artificial intelligence borrowed $219 billion through investment-grade bonds.
They plan to use most of that money to build data centers.
Many large technology companies still appear financially strong.
However, investors are becoming more worried about some companies.
The cost of protecting against an Oracle debt default rose sharply over the past year.
This means investors may need to examine corporate bonds more carefully than before.
U.S. companies issued $1.68 trillion in debt through August 2026, up 27% from the same period in 2025.
AI hyperscalers issued $219 billion in investment-grade bonds during 2026, according to Bank of America.
Most hyperscaler bond proceeds are earmarked for data-center development.
Large technology companies generally remain financially strong based on credit ratings and other measures.
The five-year cost of insuring Oracle debt rose from 0.4% to more than 2% of bond value, signaling increased perceived default risk.
