The Capital Intensity of Intelligence

How an asset is financed and how quickly it is written down are accounting choices. At current scale, those choices move reported profitability by amounts that are not small.

Two developments in the financial treatment of AI infrastructure deserve more attention than they receive. The first is the migration of capacity off balance sheet. The second is the extension of assumed useful life for accelerator hardware. Both are defensible individually. Together they make the published financial record a progressively weaker guide to physical reality.

Off balance sheet

In 2023, most large operators owned both the facility and the hardware inside it, and both appeared on the balance sheet. By 2026, a substantial share of capacity is held through leases, colocation agreements with embedded capacity commitments, and special-purpose vehicles in which the operator holds a minority economic interest alongside financial partners.

The economic substance in many of these arrangements is close to ownership: long tenors, capacity commitments that approximate the asset's useful life, and residual value risk borne by the operator. The accounting treatment differs from ownership nonetheless, and the difference flows through to reported leverage, capital efficiency and return metrics.

Useful life

Accelerator hardware was widely depreciated over three years in 2022. Several large operators now use five or six. The stated justification — that hardware remains economically productive for inference well after it is displaced from frontier training — is empirically reasonable. Older accelerators do continue to earn revenue.

The effect on reported figures is nonetheless large. Depreciation is a substantial share of the cost base for these operations. Extending useful life reduces annual depreciation, raises reported operating income, and does so without any change in cash flow or in physical reality. When several large firms make the same change in the same period, the aggregate effect on sector-level reported profitability is material and is not always foregrounded in commentary.

None of this is an allegation of impropriety. Lease accounting and useful-life estimation are ordinary areas of management judgement, and the disclosures are in the filings for anyone who reads them. The point is narrower: the headline numbers that circulate in public discussion of this sector's economics are increasingly sensitive to accounting choices that most readers of those numbers are unaware of.
