Big Tech Debt Issuance Tops $170 Billion as Credit Spreads Stay Tight

The four largest technology companies issued more than $170 billion in corporate debt in 2026 as of June 17, surpassing their total issuance for all of 2025 as credit spreads reached all-time tights.

Credit volatility was near all-time lows, creating favorable financing conditions even as borrowing tied to artificial-intelligence infrastructure increased. Investors received an all-in yield of almost 6% on the corporate bonds discussed in the June analysis.

The four biggest technology companies had issued more than $170 billion in corporate debt year to date, raising questions about whether current credit spreads can remain sustainable.

Corporate-credit spreads measure the additional yield investors demand to hold company debt instead of government bonds. Tight spreads generally reflect strong demand or confidence in borrowers, while wider spreads indicate that investors want more compensation for credit risk.

The market faces a balance between strong demand for yield and a growing supply of new debt. Higher Treasury yields can also make corporate bonds less attractive unless issuers offer additional compensation.

The combination of tight spreads and heavy issuance has created an uncomfortable tension in the credit market. If artificial-intelligence borrowing continues to rise, supply could eventually overwhelm demand and increase pressure on corporate-credit markets.
