Google Launches Universal Cart Across Search and the Gemini App

Google on October 15, 2026 launched Universal Cart in the U.S., rolling out the shopping cart it previewed at Google I/O 2026 in May across Google Search and the Gemini app.

The launch was announced by Suresh Ganapathy, Google’s senior director of product management for consumer shopping, in a post on The Keyword. Ganapathy described Google’s commerce work as proceeding on two fronts: developing agentic capabilities that act on a shopper’s behalf, and designing practical tools that give shoppers confidence and control. Universal Cart, he wrote, is built for that second track, mirroring how people already shop across Google without losing track of their items, their savings, or the merchants they trust. Checkout in the cart is powered by the Universal Commerce Protocol, or UCP.

One Cart Across Retailers

Google describes Universal Cart as an intelligent shopping cart and a hub for shopping on Google, and the company is pitching it as a holiday-shopping tool. The first of the four features Google highlights is organization: the cart saves products from multiple retailers wherever the user is shopping on Google, preserving progress across Google surfaces so a shopper does not have to start over. In Google’s example, a handbag saved from Steve Madden in AI Mode in Search, followed by a sweater from Quince and lipgloss from Ulta Beauty in the Gemini app, remains in the same cart when the shopper returns. Google presents this as a more organized alternative to browser tabs and screenshots.

The cart is built on the 60+ billion continually refreshed product listings in Google’s Shopping Graph. According to the company, that foundation lets the cart work proactively in the background, sending notifications when prices drop and when an out-of-stock item becomes available again.

Savings, Payments, and Checkout

Because the cart is built on Google Wallet, Google said it understands a user’s card perks and can help choose between payment methods, and it also surfaces relevant promo codes directly inside the cart. According to the company, the feature is aimed at shoppers who hold multiple credit cards but do not know each one’s specific benefits.

When a shopper is ready to buy, the cart offers two paths: check out with Google Pay in a few taps with participating stores directly in the cart, or transfer the items to the merchant’s own cart and finish the purchase on the merchant’s site. The simplified checkout experiences are available with merchants including Nike, Sephora, Target, Ulta Beauty, Walmart, Wayfair, and many Shopify merchants. Under either path, buyers receive order confirmations and customer support directly from the merchant, and the merchant remains the seller of record.

From I/O Preview to Launch

Google first introduced Universal Cart at Google I/O 2026 in a May 19, 2026 announcement by Vidhya Srinivasan, the company’s vice president and general manager of ads and commerce. That post said people shop across Google more than a billion times a day, activity Google described as powered by AI and the Shopping Graph. Srinivasan wrote that the cart runs on Google’s Gemini models, so it becomes more capable as the models improve, and that it provides price-history insights alongside its deal-finding and restock alerts. She also described a compatibility feature: a shopper building a first custom PC with parts added from several retailers would see the cart proactively flag incompatibilities and suggest alternatives.

At the May event, Google said Universal Cart would roll out across Search and the Gemini app in the U.S. during the summer, with YouTube and Gmail to follow. The October 15, 2026 launch brings the cart to Search and the Gemini app.

The May post also detailed the infrastructure behind the checkout experience. Google said it co-developed UCP with retail leaders earlier in 2026 and had recently welcomed new technology partners to help steer the open standard. The company said UCP-powered checkout on Google would expand to Canada and Australia in the coming months and later to the U.K., and that UCP would also come to YouTube in the U.S. and to additional verticals, starting with hotel booking and local food delivery.

Srinivasan’s post also covered the Agent Payments Protocol, or AP2, which Google created to let AI agents make purchases on a user’s behalf under strict guardrails: the user specifies brands, products, and spending limits, and the agent completes the purchase only when those criteria are met. Google said AP2 creates a verifiable link between the user, the merchant, and the payment processor, and that tamper-proof digital mandates keep the agent acting on the user’s behalf while leaving a permanent record that both sides can consult for returns. The company said in May it would begin bringing AP2 to Google products in the coming months, starting with Gemini Spark.
