⚠ The Trip Is the Product, and Trips Are Getting ShorterModerate threat

Walmart (WMT) — threat to the moat

A hundred and twenty thousand items only pays if somebody walks past most of them, and an online order never wanders.

A hundred and twenty thousand items under one roof only pays if the customer walks past most of them. That was a safe assumption when the alternative was driving to four different shops. It is a less safe assumption when the alternative is a phone.

Walmart U.S. net sales by merchandise category ($bn)264.2Grocery FY24285.5Grocery FY26114.0Gen. mdse FY24115.1Gen. mdse FY26The impulse categories that depend on somebody walking past a display have stopped growing.
Groceries added $21.3bn in two years. General merchandise added $1.1bn. An online order is a list, and a list does not wander past the televisions.

Walmart's own risk factors say so, in the flattest possible language: a greater concentration of eCommerce sales, including online grocery and the increasing role of AI-enabled platforms in product search and purchasing, "could result in a reduction in the amount of traffic in our stores and clubs, which would, in turn, reduce the opportunities for cross-store or cross-club sales of merchandise that such traffic creates"1. The company is describing the mechanism by which its own best growth engine erodes its own store economics.

The evidence that this is already happening is in the merchandise mix. In fiscal 2026 Walmart U.S. grocery net sales were $285,482 million and general merchandise $115,060 million — and general merchandise was $113,985 million two years earlier2. The impulse categories, the ones that depend on somebody wandering past a display, are the ones that have stopped growing.

An online order does not wander. It is a list, and a list has no margin on it beyond what was on the list.

The number to watch is the composition of Walmart U.S. comparable sales. In the June 2026 quarter transactions excluding fuel rose 1.5% and average ticket 1.1%3. If ticket growth turns negative while eCommerce keeps climbing, the trip has been replaced rather than supplemented, and 698.7 million square feet is a cost rather than an advantage.
