AI-related debt surged 99% in a year, raising portfolio concentration risk

MarketWatch says the rapid buildup of hyperscaler debt could force investors to hit limits tied to exposure to a single company or industry.

AI-related debt has surged nearly 99% over the past year, according to MarketWatch, spotlighting growing concentration risk for investors.

The outlet frames the rise as a “shock to the system,” warning that heavy issuance tied to hyperscalers could make it harder for portfolios to stay diversified.

MarketWatch notes the main concern is that investors may run up against portfolio concentration limits stemming from exposure to a single company or the broader AI-related industry.
