'Bond King' Jeff Gundlach Compares Nvidia's $500 Billion AI Financing Push to Bonds Backed by Bananas: 'Will Not Age Well'

Billionaire investor Jeff Gundlach is pouring cold water on the latest Wall Street scheme to keep the artificial intelligence boom rolling. The founder of DoubleLine Capital, often called the Bond King, took a sharp swipe at Nvidia and the broader push to fund massive AI infrastructure projects with a new type of financing. He compared the structure to bonds backed by bananas, suggesting the whole thing will not age well.

Gundlach was reacting to reports that Nvidia is involved in a plan to raise up to 500 billion dollars for AI data centers. The idea involves packaging future revenue from these facilities into debt securities that investors can buy. On the surface, it looks like a clever way to finance the enormous energy and computing costs that AI demands. But Gundlach sees it differently. He argues that this kind of creative financing usually shows up late in a cycle, when traditional sources of capital are getting stretched or when the underlying assets are too speculative to support normal borrowing.

The comparison to banana bonds is not random. In the 1930s, a company actually issued bonds that were meant to be repaid with proceeds from banana sales. That scheme collapsed when the banana crop failed. Gundlach's point is that tying debt to a single, volatile revenue stream is a risky bet. If AI demand slows, or if the promised returns from these data centers do not materialize, the bonds could sour quickly.

He also hinted that the move could be a sign that risk markets are close to a peak. When investors start accepting increasingly exotic structures to keep a bull market alive, it often marks a turning point. Gundlach has been cautious on equities for a while, and this latest development seems to reinforce his view that the easy money has been made. For now, the market is still buying the AI story, but the Bond King is clearly betting that the bill will come due eventually.
