Imagine this: you search for sneakers, add them to a cart, and later see the same cart when you open Gemini. On May 19, 2026, Google announced this idea as “Universal Cart” at Google I/O 2026. Google describes it as a new shopping hub that works across different stores and across Google services. The first rollout is planned for Search and the Gemini app in the U.S. in summer 2026, with YouTube and Gmail coming later. (blog.google)
Universal Cart is not just a place to save items. Google says that after you add a product, the cart can start working in the background. It can look for deals, track price drops, show price history, and send alerts when an item is back in stock. Because the system uses Gemini AI, it can also try to solve problems for you. For example, if you are buying parts for a custom PC from different shops, it may warn you if some parts do not match and suggest other options. (blog.google)
Google also connects the cart with Google Wallet and Google Pay. That means the system may notice card perks, loyalty rewards, and special store offers, helping shoppers find extra savings. When it is time to buy, Google says some stores will let users check out with Google Pay in just a few taps, while other purchases can be moved to the store’s own website. Google has already named early partners such as Nike, Sephora, Target, Walmart, and Wayfair. (blog.google)
Behind this feature is Google’s bigger plan for “agentic commerce,” where AI can do parts of shopping for people. Google says it is also developing systems called UCP and AP2 to support checkout and payments, with user-set limits and a clear record of what the AI does. If this works well, online shopping may become faster and easier—but it also shows how quickly AI is moving from giving advice to taking action. (blog.google)
