AI Shopping Agents Challenge Amazon's Retail Media Model
AI shopping agents could disrupt the retail media business model of Amazon and Walmart by taking over product search, comparison, and purchase. Currently, Amazon and Walmart control 88% of the US retail media market, valued at $74.4 billion. Amazon is attempting to block external agents like Meta's Muse and Perplexity's Comet to maintain control, while Walmart is opening its infrastructure to AI agents since October. This shift threatens the lucrative advertising revenue, as brands pay for prominent placement on retailer platforms. The future of retail media will depend on how these platforms adapt to the agentic commerce revolution.
