Bite: Is the AI investment boom running out of steam? | Brad Olsen

Companies are borrowing billions to fund AI, energy infrastructure and expansion. But with global debt at record levels and borrowing costs putting pressure on businesses, are investors becoming more cautious?

In this Shared Lunch Quick Bite, Infometrics Chief Economist Brad Olsen looks at the surge in corporate borrowing, the risks behind soaring AI valuations, and why some investors are starting to question whether the potential returns justify the price.

Plus, how higher borrowing costs are changing investment decisions, from corporate expansion to property and bonds, and why understanding risk matters more than ever.

This conversation was recorded before the Reserve Bank's 28 October 2026 decision to hold the Official Cash Rate.
