How shopping with AI is evolving
Shopping becomes an agentic service
Shopping becomes an agentic service
At I/O 2026 Google stopped thinking of shopping as a sequence of web pages to scroll and started thinking of it as a service the user delegates. Universal Cart unifies the cart across Search, Gemini, YouTube, and Gmail. Universal Commerce Protocol tries to write the open standard through which Google's AI agents and those of its partners (Shopify, Amazon, Walmart, Meta, Etsy, Wayfair, Target) talk to marketplaces and complete transactions on behalf of the user. Auto Browse in Chrome shops on its own, stopping only at checkout and login. Three announcements, one clear direction: the next level of interaction with an online store is not a page to visit but an instruction to issue.
Behind Universal Cart there is a more ambitious piece of infrastructure. At I/O 2026 Google published the Universal Commerce Protocol (UCP), an open-source standard co-developed with Shopify, Etsy, Wayfair, Target, Amazon, Walmart and Meta. Its job is to give AI agents a common language to read catalogs, manage carts and complete checkouts. Consumers see it as Universal Cart; for merchants, the adoption work starts now.
At I/O 2026 Google brings Gemini 3 inside Chrome with a new side panel and an agentic feature called Auto Browse. It compares products across two tabs in parallel, fills forms reading data from a PDF, runs multi-step research, and always pauses before checkout or sign-in. Available now to US AI Pro and Ultra subscribers. Chrome for Android joins in late June, with Gemini Spark integration coming in the fall.
A single cart across Search, Gemini, YouTube, and Gmail. Add a product and Gemini starts hunting for deals, tracking price history, and alerting you when it's back in stock. US rollout this summer.
