Walmart is set to deploy a new generative AI tool called Wally later this year that’s been designed for internal merchants and developers. 

In its Q4 earnings call last week, CEO and director Doug McMillon said Wally will act as an interactive sales agent for stores, pinpointing the root cause of ongoing issues like out-of-stock items and overstocked inventory. Still in a beta phase of development, the tool can also be used to quickly automate the generation of accurate sales reports to identify new shopping trends and determine how well new products are performing on shelves. 

Walmart will roll Wally out to all of its internal developers in North America and India later this year. This is the third AI tool the retailer has unveiled in the last 12 months—it joins an interactive c-commerce shopping assistant for consumers and a forecasting tool powered by Helios AI that can predict the price, availability and climate risk of agricultural products. These tools have saved developers an estimated four million hours of work to date, McMillon adds. 

Walmart generated US$180.6 billion in global revenue during its Q4 sales period (from November 2024 to January 2025)—a 5.3% increase from the same period in 2023. Despite this growth, Amazon managed to overtake Walmart in Q4 revenue for the first time last year, generating US$187.8 billion during the holiday shopping season.
