Costco Wholesale Corporation COST suggests that artificial intelligence (AI) is a small but important digital opportunity, even at this early stage. Management said consumers are increasingly using AI to research products and services, and Costco is working with leading AI companies to improve how its value proposition is presented to current and potential members. The strategy is not about changing the core model. It is about making Costco products easier to find through AI search.
The key step is to improve online product pages so that large language models can better capture Costco’s quality, pricing and member value. This matters because some Costco offers are hard to explain through a regular search. Management pointed to appliances, where the real value includes delivery, installation and haul-away and to tires, where installation, road hazard coverage and nitrogen are included. AI search can present that broader value more clearly.
The early signals are notable. AI-generated traffic remains low, but Costco saw triple-digit growth in the third quarter of fiscal 2026, and this traffic carried the highest conversion rate of any source coming to its site. That sits alongside strong digital engagement, with site and app traffic up 37% and digitally enabled comparable sales up 21.5%. AI search is not yet a major revenue engine, but it could become a useful driver for Costco’s digital business.
