Google Launches AI-Powered Universal Cart for Shoppers
Google announced the Universal Cart at Google I/O, an AI-powered, cross-merchant shopping cart that will operate across Google Search, Gemini, YouTube and Gmail. The cart tracks deals and price history, alerts on restocks and incompatibilities, suggests alternatives, and lets shoppers check out with Google Pay or transfer items to a merchant’s site. Universal Cart will roll out in Google Search and Gemini in the U.S. this summer, with YouTube and Gmail access to follow. Google says retailers need take no action for products to appear but can integrate for seamless checkout via the open Universal Commerce Protocol. Launch partners named by Google include Nike, Sephora, Target, Ulta Beauty, Walmart, Wayfair and Shopify merchants such as Fenty and Steve Madden. Industry observers caution the feature could reduce direct retailer traffic and complicate merchants’ merchandising strategies.
A major product launch from Google that embeds AI into checkout and cross-merchant commerce can materially affect retailer traffic, checkout flows, retail media and payments; industry-wide implications warrant high importance.
