Big Tech’s AI binge is rattling credit markets

The AI capex party got a bond-market bill

Big Tech has been acting like it found a cheat code for growth: spend wildly on AI infrastructure now, worry about the balance sheet later. According to the piece, tech giants have issued a record $182 billion of investment-grade bonds in 2026 so far — a jaw-dropping 1,300% jump year over year.

That’s not just a headline number. It means the AI arms race is no longer living only in earnings calls and glossy product demos. It’s showing up in the plumbing of the financial system, where lenders and bondholders are basically asking, “Cool, but who’s paying for all this?”

Credit investors are suddenly less zen

The tell is in credit default swaps, the financial world’s insurance policy for debt. CDS spreads on names like Oracle, Amazon, Google, and Microsoft have climbed to around 75 basis points, near the highest level in at least seven years.

And even if you strip Oracle out of the mix, the group is still around 49 basis points, the highest since at least 2018. In other words: this isn’t just one company being weird. Investors are starting to treat AI spending like a shared credit story, not a solo act.

Why you should care

For equity investors, this is the classic “growth is expensive” tradeoff. If these companies keep prioritizing data centers, chips, and power-hungry infrastructure, they may keep winning the AI race — but they’re also taking on more leverage and making debt markets pay attention.

Big picture: the AI boom is no longer just a stock-market story. It’s becoming a credit-market story too, and that usually means the bill is getting real.
