Google launches a shared shopping cart across Search and Gemini in the U.S.

Google began rolling out Universal Cart in the United States on October 15, bringing products from multiple retailers into one saved cart across Search and the Gemini app. The launch connects shopping research with price alerts, payment advice and checkout, while leaving merchants responsible for the purchases shoppers ultimately make.

The tool moves from preview to rollout ahead of holiday shopping. Google first showed it at Google I/O in May, according to TechCrunch. Its arrival now gives U.S. shoppers a place to retain products they find across Google, rather than reconstructing a shortlist each time they return.

A shopping shortlist, not an autonomous buyer

Google draws a distinction between tools that act on someone’s behalf and tools that help shoppers stay organized and in control. It puts Universal Cart in the second group. The company presents it as a hub for keeping track of products, offers and purchases—not as an agent tasked with deciding what to buy.

That starts with continuity between Google’s shopping interfaces. In the company’s example, someone saves a Steve Madden handbag in Search’s AI Mode, then adds a Quince sweater and Ulta Beauty lipgloss in Gemini. The products remain in the cart for a later visit, even though they came from different stores and were saved through different Google services.

Watching products—and weighing ways to pay

The cart also monitors changes after an item is saved. Google says it runs on the Shopping Graph, its collection of more than 60 billion continually refreshed product listings. That information supports notifications when a saved product’s price drops or an unavailable item returns to stock, so the cart is more than a static list of links.

A separate layer addresses how to pay. Universal Cart is built on Google Wallet, and Google says it can use card benefits to help shoppers choose a payment method. The example is someone with several credit cards who does not know each card’s perks. Relevant promotional codes also appear inside the cart, bringing those offers alongside the saved products.

One hub, but retailers still handle the orders

Checkout uses Google’s Universal Commerce Protocol, or UCP. The protocol connects the shopping experience to the purchase step. The two checkout options give shoppers a choice of where to finish: through Google Pay inside Universal Cart, or after a handoff to the retailer’s own cart.

Google names Nike, Sephora, Target, Ulta Beauty, Walmart, Wayfair and many Shopify merchants as stores where shoppers can try these simplified checkout experiences. Its announcement describes the options with participating merchants; it does not promise that every retailer offers checkout inside Google. The choice of route therefore sits alongside the choice of store.

The responsibility for an order stays the same whichever route the shopper takes. The merchant remains the seller of record—the business responsible for the sale—and sends the purchase confirmation directly. Customer support also comes from the merchant. Universal Cart brings the shopping process together, but Google’s launch leaves that retailer relationship intact.
