Amazon's $137.2bn of leases it hasn't opened

Amazon's 10-Q for the June quarter discloses $137.2bn of leases not yet commenced, a number more than 60 per cent larger than the capex guidance figure the market actually tracks.

Key takeaway

Amazon has signed $137.2bn of data-centre leases on buildings that have not yet been delivered.

Amazon filed its Form 10-Q for the quarter ended 30 June with the US Securities and Exchange Commission on Friday 31 July, disclosing $650.0bn of total contractual commitments⁠1. One line inside that table appeared in no earnings-call commentary: $137.2bn of leases not yet commenced, meaning buildings Amazon has signed for where the facility has not yet been delivered, overwhelmingly data-centre and power infrastructure. Unconditional purchase obligations, which the filing says include long-term energy procurement, add a further $130.1bn⁠2.

Cash capital expenditure, the money actually spent on physical assets in the period, ran to $53.1bn in the quarter against $31.4bn a year earlier, a rise of 69 per cent, and $96.3bn across the first half⁠3. Amazon raised full-year 2026 guidance to roughly $220bn, citing memory costs and continued cloud investment. That figure counts only the cash it expects to lay out this year.

Guidance and the lease line measure different things, and the gap between them is where the planning problem sits. A lease not yet commenced is a building somewhere that a landlord is contracted to deliver and Amazon is contracted to take, with a grid connection behind it that some system operator has to find. None of that shows up in the number quoted when a campus goes before a planning committee.

Virginia's regulator issued Amazon's Lake Anna cooling-water discharge permit on 21 July, assessed as one campus drawing on one river. The pipeline sitting in the 10-Q is a portfolio-scale commitment being permitted one site at a time, by bodies that see only the site in front of them.

Deep Analysis

In plain English

When a company files its quarterly results with US financial regulators, it has to list what it spent this year and, separately, what it has already promised to spend in future, even on buildings that are not finished yet. Amazon's filing shows it has signed $137.2bn worth of data-centre leases for facilities that have not opened, which is more money than its entire announced budget for building data centres this year. That gap matters because most headlines about Amazon's spending only report the smaller, current-year figure.

Deep Analysis
Root Causes

The structural cause is that data-centre leasing separates the signing of a long-term contract from the physical delivery of the building, unlike direct capital expenditure which Amazon records as spending occurs. A hyperscaler can lock in years of future capacity with a lease commitment long before construction finishes, which lets its balance sheet carry contracted growth that its published capex guidance, a cash-flow figure for the current year only, does not capture.

A second structural driver is Amazon's own disclosure that unconditional purchase obligations, including long-term energy procurement agreements, total $130.1bn, reflecting that securing future power supply now requires the same kind of multi-year contractual commitment as securing the buildings themselves.

What could happen next?
  • Meaning

    Headline hyperscaler capex guidance understates the true scale of contracted future data-centre capacity by tens of billions of dollars.

  • Consequence

    Communities and regulators debating local moratoria may be assessing a materially smaller pipeline than the one Amazon has already committed to build.

This Event
Amazon's $137.2bn of leases it hasn't opened
The commitment Amazon has already contracted for sits in a filing table rather than in guidance, so the counties weighing individual campuses work from the smaller number.

Seven projects, one linked to Google, asked SEA this month for rulings that they fall outside full environmental review; four declared diesel-storage volumes just under the review-triggering tonnage, mirroring the mechanism Alto Jahuel used in July. The clustering suggests the threshold is being engineered, not sized to need.

Ireland's planning appeals body refused the €1.5bn Killala data centre on 17 September, overturning Mayo County Council's 2025 grant for lack of a fixed grid-connection agreement and no corporate renewable power-purchase agreement. The ruling makes matched-power evidence, not planning consent alone, the deciding factor.

Aragon holds 3,600 MW of granted grid access against 108 MW built.
