Hidden AI Bills: What Big Tech’s Off-Balance-Sheet Debt Could Mean for Investors

A Nikkei-led review finds roughly $1.65 trillion in future AI infrastructure commitments by Microsoft, Meta, Alphabet, Amazon, and Oracle buried in SEC footnotes rather than on headline debt. Many of these obligations are financed via long-term leases and private credit, which can keep reported debt looking reassuring even as leverage grows. If AI demand slows, these off-balance-sheet commitments could become impairment charges, affecting shareholders and lenders. While cash flows remain strong for these giants, the key takeaway for investors is to examine footnotes and total commitments beyond traditional debt figures during earnings season.
