Walmart has been awarded patents by the US Patent and Trademark Office (USPTO) for AI tools that help set pricing across its e-commerce platforms. One of these patents contains systems and methods for automatically updating item prices across e-Commerce platforms. The second patent uses machine learning to predict the demand of various items and recommend prices. This move has raised concerns among consumers about dynamic pricing and surveillance pricing, which are currently subject to nationwide debates involving the Federal Trade Commission (FTC), several state legislatures, and several state governments. Walmart has also implemented Digital Shelf Labels (DSLs) across its stores and plans to expand this technology chain-wide within the next year.
