Selling the Supply ChainNarrow moat
Walmart (WMT) — moat facet
Having built a logistics network to fill its own shelves, Walmart now rents it out.
Having built a logistics network to supply its own stores, Walmart now rents it out.
Walmart Fulfillment Services stores, picks, packs and ships marketplace sellers' goods through the same 192 American distribution facilities and the same store network that serve Walmart's own inventory1. The company describes the offering plainly: supply chain and fulfilment capabilities to online marketplace sellers, alongside advertising solutions and data analytics and insights for suppliers and brands2.
This is the most Amazon-like thing Walmart does, and the logic is identical. A fulfilment network is a fixed-cost asset whose unit economics improve with volume; selling capacity to third parties raises utilisation without raising the fixed cost. It also deepens the marketplace's moat, because a seller whose inventory sits in Walmart's warehouses has a real switching cost for the first time — the rest of the marketplace relationship has none.
The strategic ambition goes further than sellers. Walmart's international business already runs an equivalent motion, and the company has been explicit that membership, advertising, marketplace, fulfilment services and financial services are "mutually reinforcing pieces" of one omnichannel model3. Read that as a statement that the supply chain is becoming a product rather than a cost centre.
The limit is capacity. Walmart's network was scaled for its own volumes, and every pallet of a seller's inventory occupies space that could hold Walmart's — which is a real constraint in a business whose capital expenditure is already $26,642 million a year4.
There is no disclosed fee, so the reading has to come from Walmart's eCommerce economics. Management named improved eCommerce economics as a driver of the 20.6% rise in Walmart U.S. operating income in the June quarter5; fulfilment services are the largest single reason that improvement is possible.
Selling fulfilment to marketplace sellers raises utilisation of a network Walmart had to build anyway and creates the only real switching cost the marketplace relationship has. It is early, capacity-constrained and priced against Amazon's, but the direction is clearly toward the supply chain being a product rather than a cost.
The network being rented to marketplace sellers is the same network Walmart is spending heavily to automate. A network being rented profitably should bring that ratio down; it has risen from $20,606M three years ago.
