- • Hidden obligations are roughly 5x the companies' combined reported capex of ~$600 billion.
- • Uncommenced data-center leases hit $1.2T; chip purchase commitments totaled $1.9T across nine firms.
- • Meta holds $347B in unstarted leases; Alphabet discloses $811B in purchase commitments as of June 30.

$3T in off-balance-sheet AI commitments
WSJ analysis of securities filing footnotes for nine major tech companies reveals roughly $3 trillion in off-balance-sheet obligations predominantly tied to AI infrastructure — data-center leases and chip purchase contracts.
5x the $600B in reported capex
The $3T in hidden commitments far exceeds the companies' combined reported capital expenditures of approximately $600 billion over the prior year, and is roughly triple their on-balance-sheet lease and long-term debt obligations.
Uncommenced leases: $1.2T
Data-center lease commitments not yet started reached $1.2 trillion — roughly four times the prior-year level — reflecting massive planned capacity expansion.
Purchase commitments: $1.9T
Purchase commitments, predominantly chip orders and hardware supply contracts, totaled $1.9 trillion across the nine companies analyzed.
Meta: $347B in unstarted leases
Meta alone holds $347 billion in uncommenced lease commitments, including its Hyperion data-center project.
Alphabet: $811B in purchase commitments
Alphabet disclosed $811 billion in purchase commitments as of June 30, the largest single-company figure in the WSJ analysis.
Commitments are non-cancellable
The off-balance-sheet obligations generally cannot be canceled, locking these companies into AI infrastructure spending regardless of future demand fluctuations or market shifts.
Nine major tech companies analyzed
Analysis covers Alphabet, Amazon, Meta Platforms, Microsoft, Oracle, Nvidia, Broadcom, SpaceX, and AMD — reflecting the breadth of Big Tech's AI infrastructure bet across hardware and cloud sectors.

What This Means
This analysis exposes a major gap between Big Tech's publicly reported AI spending and its true financial exposure: $3 trillion in off-balance-sheet commitments — mostly non-cancellable — dwarfs the ~$600 billion in annual capex that dominates investor and media attention. For markets, this reframes the AI infrastructure race as far more financially consequential and irreversible than quarterly capex numbers suggest. If AI demand falters or shifts, these nine companies face enormous sunk costs in data-center leases and chip contracts they cannot easily exit. The scale of the commitment signals that Big Tech is betting its next decade of infrastructure on sustained AI growth, with limited ability to course-correct.
Sentiment
Mostly concerned about hidden leverage and sunk costs, with some nuanced views that structures spread risk rather than create imminent stress
“Massive spending commitments for data-center leases and chips aren’t on companies balance sheets. Nine tech comp had $3 trillion of off-balance-AI obligations that are growing faster than traditional “capex,” which was about $600 billion over past year.”
“The $3T “hidden AI debt” number is not the story. WSJ just put a headline on the shadow capex we’ve been tracking for a while. Purchase commitments + leases that have not started. Most of it never hits the balance sheet. The $3T is real. The interpretation is not. ... 1. Most of this is contract value, not a hard legal obligation to pay. ... This is risk offload, not hidden leverage.”
“Big Tech's AI buildout carries roughly $3 trillion in commitments that are not yet showing up on balance sheets, per @WSJ. About $1.9 trillion of that is purchase commitments for chips, servers, and cloud capacity. Alphabet accounts for $811 billion of that by itself, including energy contracts that run through 2054. Another $1.2 trillion is leases already signed but not yet started...”
“The $3 Trillion AI Bill Big Tech Isn’t Putting on Its Balance Sheet. The @WSJ reports that 9 top tech companies have ∼$3 trillion in off-balance-sheet commitments, mostly tied to AI. ... Risk: If AI demand doesn’t match projections, companies are still locked into paying for infrastructure they can’t profitably use.”
“Big Tech’s AI bill is much bigger than reported capex suggests. WSJ estimates roughly $3T of off-balance-sheet AI commitments, versus about $600B of traditional capex over the past year. a lot of the AI buildout is becoming a financing story”
Split
~70/30 concerned/nuanced: majority highlight irreversible financial exposure and risk if AI demand disappoints; minority argue commitments are mostly flexible contracts or risk-sharing with private capital, not hidden leverage on balance sheets (~4:1 split in quality posts).
