⚠ Renting Out Capacity You May NeedLow threat

Walmart (WMT) — threat to the moat

Capacity sold to third parties is capacity that has to be built twice.

Walmart's fulfilment network was built to fill its own shelves. Every pallet of a marketplace seller's inventory occupies a slot that was sized for Walmart's.

Every pallet of a seller's inventory occupies a slot sized for Walmart's, which means the capacity has to be built twice — and the second build is what the capex line is paying for.

That is a genuine constraint rather than a theoretical one. The company spent $26,642 million on property and equipment in fiscal 2026, up from $20,606 million two years earlier1, and names supply chain automation and fulfilment capability as a principal use of it2. Capacity that is being sold to third parties is capacity that has to be built twice — once for the seller and once for the growth in Walmart's own volumes — and the second build is what the capital expenditure line is paying for.

The economics only work if utilisation genuinely rises. A fulfilment network running at full capacity with third-party goods earns a fee on every cubic foot. The same network running at half capacity because Walmart over-built for a marketplace that did not arrive is a very expensive mistake, and the lead time on the decision is years.

There is also a competitive subtlety. Walmart is selling logistics to sellers who also sell on Amazon, and those sellers will use whichever network is cheaper for a given order. The service is therefore priced against Amazon's, by a company with less scale in parcels and a network designed for pallets, which caps the margin.

And the customer-facing risk is the obvious one: a fulfilment failure by Walmart on a third-party order is a failure the customer attributes to Walmart.

Watch capital expenditure against operating cash flow: $26,642 million against $41,565 million in fiscal 2026, about 64%3. A network being rented profitably should bring that ratio down. It has been going the other way.
