Solution

Walmart describes a multi-surface AI implementation for holiday commerce across discovery, purchase, fulfillment, and support. On Walmart.com, AI uses shopper preference and prior search signals to personalize homepage content, while a GenAI-based personalization feature in Mexico broadens product recommendations. A GenAI-powered shopping assistant and GenAI search experience interpret natural-language gift queries and return cross-category results, supported by GenAI-powered product reviews, product summarizations, and an AI-driven comparison feature to help customers evaluate items. In stores, Sam’s Club’s AI-powered exit technology uses computer vision to verify purchases as members leave. For fulfillment, an AI-driven geospatial platform unifies transaction, network catchment, customer insight, and external data into a geo-grid, and a slot optimization data science model allocates grocery delivery capacity from store labor and physical constraints. A GenAI-powered Customer Support Assistant then handles order lookup and returns.

Data flow

Customer preference and search signals feed Walmart.com personalization, GenAI shopping assistance, search, reviews, summaries, and comparisons shown to shoppers on the web and app. For fulfillment, transaction data, network catchment, customer insights, and external data are unified in an AI-driven geospatial platform, while store picker availability and physical constraints feed a slot optimization model that determines delivery coverage and windows. Sam’s Club exit scans and support interactions are then served directly to members and customers.
