Google unveils unified shopping cart

Google used its May 19 I/O 2026 keynote to introduce Universal Cart, a new shopping hub that pulls products together across Search, Gemini, YouTube and Gmail. The company said the feature tracks deals and price drops in the background, surfaces price history and back-in-stock alerts, and can help users complete purchases with Google Pay at participating merchants. Google tied the feature to its broader push into what it calls “agentic commerce,” alongside Gemini Spark and related payments tools announced at the conference. Ynet reported the shopping capability as part of Google’s wider effort to build AI agents that can act on a user’s behalf. ### What exactly did Google announce on May 19? Google said on May 19 that Universal Cart is “an intelligent shopping cart” and a new shopping hub inside its services. According to Google’s product post, users can add items while browsing Search, chatting with Gemini, watching YouTube or reading Gmail, and the cart then keeps monitoring those items after they are added. (blog.google) Ynet’s May 19 coverage described the feature as a unified shopping cart that can track deals, compare products and buy on users’ behalf as part of the company’s I/O presentation. That report linked the shopping tool to Gemini Spark, the new always-on assistant Google presented during the keynote. ### How does the cart work once something is added? Google said the cart begins working “in the background” as soon as a product is added. (blog.google) The company said it can find deals and price drops, show price-history information and notify users when an item returns to stock. Google also said the cart uses Gemini models to reason across items from different sellers. (ynetnews.com) In one example, the company said a shopper building a custom PC could add parts from several retailers and the cart would flag compatibility problems and suggest alternatives. 9to5Google reported the same example from Google’s materials and said Gemini could identify incompatible parts without a direct prompt.

Google said people shop across its services more than a billion times a day and that its Shopping Graph contains more than 60 billion product listings. The company described that catalog as the data layer behind its shopping tools and said Universal Cart builds on that existing infrastructure. Google has been layering shopping features into Gemini ahead of I/O. (blog.google) In a November 2025 holiday-shopping post, the company said Gemini users in the United States could already see shoppable listings, comparison tables, prices from across the web and places to buy directly inside the Gemini app. ### Can it actually complete a purchase for you? (blog.google) Google said Universal Cart is built on Google Wallet and can take account of payment-method perks, loyalty information and merchant offers when suggesting ways to save. The company said users can check out with Google Pay “in just a few taps” at many participating brands, or transfer items to a merchant site to finish the purchase there. (blog.google) 9to5Google reported that Google is also launching an Agents Payment Protocol, or AP2, to let AI agents “make secure payments on your behalf,” with rollout beginning in Google products including Gemini Spark. Google’s own shopping post said the broader foundation for the feature includes the Universal Commerce Protocol and payments infrastructure for agentic checkout. (blog.google) ### Which merchants and products are included first? Google said select checkout features will be available across merchants including Nike, Sephora, Target, Ulta Beauty, Walmart, Wayfair and Shopify merchants such as Fenty and Steve Madden. The company added that, even when checkout happens through Google’s tools, “the brand stays the merchant of record.” (9to5google.com) The company said Universal Cart will begin rolling out across Search and the Gemini app in the United States this summer. Google said YouTube and Gmail support will follow later, making those next rollout points the clearest milestones after the I/O announcement on May 19. (blog.google)
