How Sponsored Prompts Work

The Sponsored Prompt feature is designed to drive brand engagement and personalized recommendations through Sparky conversations, according to a company presentation viewed by the Wall Street Journal 1

. During testing, Walmart displayed sponsored prompts on Walmart.com, and when users clicked on them, Sparky would respond with an answer followed by a click-to-buy advertisement for a featured product 1

This approach represents Walmart's strategy to protect its dominant retail position as AI-driven, autonomous shopping agents begin changing consumer behavior patterns 1

Competitive Landscape and Challenges

Walmart's move comes as competitors are aggressively pursuing similar strategies. Amazon has introduced Sponsored Prompts inside its AI chatbot Rufus, which boasts 250 million active customers this year 1

. Amazon CEO Andy Jassy reported that customers using Rufus during shopping trips are 60% more likely to complete a purchase, with the platform on track to deliver over $10 billion in incremental annualized sales 2

However, Walmart faces significant challenges with its current implementation. Sources familiar with the matter told the Wall Street Journal that engagement and click-through rates in Walmart's Sparky pilot remained low 1
