Big Tech's AI buildout hides $4.49 trillion in off-balance-sheet promises

Alphabet, Meta, Anthropic, Microsoft, Amazon, Oracle and Nvidia have disclosed a combined $4.49 trillion in off-balance-sheet obligations, according to @KobeissiLetter on X. The pile covers lease payments that haven't started yet, data-center commitments, equipment purchases and other contractual promises. It's the bill for the AI infrastructure race, and it isn't booked as debt.

Alphabet carries the heaviest load at $1.08 trillion. Anthropic follows at $865 billion, with Meta at $810 billion. Against those numbers, the same companies' on-balance-sheet obligations — long-term debt plus existing lease liabilities — total just $758 billion, making the off-book commitments nearly six times larger.

Add it all up and the seven companies face roughly $5.25 trillion in combined financial obligations. The disclosures lay out how much future spending is already locked in by the data-center and compute buildout, even before any new deals get signed.
