Google announces Universal Cart at I/O

Google said on May 19 at its I/O developer conference that it is launching Universal Cart, a shopping cart designed to work across Google surfaces including Search, YouTube, Gemini and Gmail. In a company blog post, Google called it “an intelligent shopping cart” and said users can add items while browsing Search, chatting with Gemini, watching YouTube or reading Gmail, then return to one place to review purchases. (blog.google) The product sits inside a broader Google shopping push tied to what the company has been calling “agentic commerce.” Google said Universal Cart builds on its Universal Commerce Protocol, or UCP, and on payments infrastructure meant to support AI agents that can complete purchases on a user’s behalf. In a separate March post, Google said UCP had been updated so shopping agents could save multiple items to a cart, pull real-time price and inventory data, and connect shoppers to merchant loyalty programs. (blog.google) That makes Universal Cart less a standalone checkout button than a new coordination layer for shopping activity across Google’s own products. Google’s description says the cart is “proactive,” suggesting it will collect items from different touchpoints rather than require a shopper to stay inside a single retailer session or app. Forbes, in a May 20 analysis, said the launch ties shopping more closely to Google’s AI assistant layer and could enable checkout flows that span multiple Google services and advertisers. (blog.google) Google introduced Universal Cart during I/O 2026, held May 19-20 at Shoreline Amphitheatre in Mountain View, California and online. The company’s roundup of I/O announcements listed Universal Cart alongside Gemini Omni and Google Antigravity as part of dozens of launches across AI, search, Android and commerce. (blog.google) The immediate question is how broadly the system will work with merchants. Google said Universal Cart “works across different merchants and services,” but its post did not spell out at launch which retailers had integrated it, what fees would apply, or when all features would be available to users at scale. The company instead framed the cart as a hub for shopping on Google and as the next step in assembling the pieces for AI-assisted buying. (blog.google) The next place to watch is Google’s shopping and I/O materials. Google’s May 20 I/O recap and its Universal Cart launch post are the company’s main public documents so far, and any rollout details for merchants, payments or user availability are likely to appear there first.
