A shopper watches a YouTube review, adds a pair of headphones to a cart and closes the tab. Three days later, the price drops. An artificial intelligence agent buys them.
No redirect. No checkout page. No decision.
At Google I/O, Google unveiled Universal Cart, a Gemini-powered hub that follows a consumer across Search, YouTube and Gmail, holds products from multiple merchants in one cart, tracks prices continuously and can execute checkout the moment conditions are met. Consumers can also check out themselves through Google Pay or transfer items to the merchant’s site and buy.
The full stack that Google announced includes:
- Universal Cart, an intelligent cross-surface cart built on Google Wallet that monitors deals, price drops and stock availability continuously. It’s launching across Search and the Gemini app in the United States this summer, and YouTube and Gmail will follow.
- Universal Commerce Protocol (UCP) expansion to Canada, Australia and the United Kingdom, plus new verticals, including hotel booking and local food delivery.
- Agent Payments Protocol (AP2) rollout to Google products in the coming months, starting with Gemini Spark, a personal AI agent coming soon.
From Storefront to Infrastructure Layer
The Universal Cart is a consumer product. AP2 is a commercial architecture. The two products push the shopping journey from discovery to price monitoring to checkout inside Google’s surfaces rather than onto the retailer websites built to control it.
Despite Google’s repeated attempts to become a commerce destination, from Froogle in 2002 to Google Express to its current Shopping tab, the company has remained a listing service that sends consumers somewhere else to buy. The transaction, the customer relationship and the post-purchase experience have always happened in someone else’s ecosystem.
