AI infrastructure debt jumps to $270 billion

MarketWatch says AI-related corporate debt has risen 99% year over year to about $270 billion, with Amazon, Alphabet, Meta, and Oracle among the hyperscalers issuing investment-grade bonds to finance AI infrastructure. Amazon alone has raised $92 billion this year, including a $25 billion bond deal. The borrowing wave is increasing overall investment-grade supply and raising questions about credit exposure if AI infrastructure demand or market conditions turn.

Key details: AI-related corporate debt has reportedly reached $270 billion, Hyperscalers are issuing bonds to finance AI infrastructure buildouts, Amazon has raised $92 billion this year, including a $25 billion bond deal.

Why it matters: The AI buildout is increasingly a credit-market story, so infrastructure risk is moving from chips and power into bond supply and lender concentration.
