AI Capex Doubts Deepen as Third IPO Shelved in October

A South Korean IPO's poor reception has become the latest casualty in a string of AI-trade disappointments. October alone has seen three planned flotations for data-center providers shelved, each backed by major AI players including Nvidia, Blackstone and SoftBank.

The pattern signals growing investor skepticism toward the capital expenditure assumptions underpinning the AI infrastructure boom. Rather than rewarding growth narratives, markets are now demanding proof that massive data-center buildouts can generate sustainable returns.

For traders, this shift matters beyond equities—AI-linked sentiment has been a key driver of risk appetite across asset classes, and repeated IPO failures could signal a broader repricing of tech-sector risk premiums heading into year-end.
