Google Launches Universal Cart: A New AI Shopping Cart for Multiple Online Stores

Google launched Universal Cart in the United States on October 15, 2026. The new AI-powered shopping cart brings products from multiple online stores together in Google Search and Gemini. Users can track prices, find discount codes and check out more easily—without constantly switching between websites.

Google confirmed the launch in an official announcement. The company first unveiled Universal Cart at Google I/O in May, but is now rolling it out to U.S. consumers just ahead of Black Friday and the holiday season.

Universal Cart works differently from a traditional shopping cart. Online stores typically let shoppers save only products from their own catalog. Google, by contrast, lets users collect items from different retailers in one central place.

For example, someone who finds a pair of shoes through Google Search can save it and later add a pair of headphones through Gemini. Both items then appear in the same cart, even if they come from different sellers.

At launch, the feature works with Google Search, Google Shopping, AI Mode and the Gemini app. Google plans to connect Universal Cart to Gmail and YouTube later, but hasn’t said when those additions will arrive.

The technology is powered by Gemini models and Google’s Shopping Graph, a vast product database that the company says contains more than 60 billion listings. This allows the cart to gather and track information from different stores.

Universal Cart does more than save products: it also keeps an eye on prices and availability.

If a saved item gets cheaper, Google can send a notification. The same applies when an item that was temporarily out of stock becomes available again. Users no longer have to keep checking different online stores themselves.

Google is adding more ways to save, too. The AI can surface relevant discount codes and check whether a different payment method offers extra perks.

For the latter, Google uses information from Google Wallet. If someone has saved multiple payment cards, the cart can take into account cashback, reward points or card-specific offers.

When Google introduced Universal Cart in May, it also described a feature that could flag incompatible products. If someone is picking parts for a new computer, for example, the system could identify when a processor won’t work with the chosen motherboard. Google does not explicitly mention this compatibility check as part of the current rollout in its latest announcement.

Google offers two ways to complete purchases through Universal Cart.

At participating retailers, customers can pay directly through Google using Google Pay. For other stores, Google helps transfer selected products to the retailer’s own cart, where the customer completes the purchase on its website.

Retailers working with Google include Nike, Sephora, Target, Walmart, Wayfair and several Shopify stores.

Despite its name, Universal Cart doesn’t mean shoppers can automatically buy items from different stores in a single transaction. Google groups products by retailer and offers the available payment options for each.

Behind the scenes, Google uses the Universal Commerce Protocol (UCP). The standard is designed to make it easier for AI systems and online stores to connect product information with purchasing processes.

The retailer remains responsible for the actual sale, order confirmations and customer service. In its official explanation of Universal Cart, Google also describes how participating sellers can share order details, allowing customers to track deliveries, among other things.

Google stores cart and order information in Google Wallet. However, not every store shares order details, so the overview may be incomplete. Gemini chats also can’t yet display cart information or order updates directly in every case.

For now, Universal Cart is available only in the United States. Google hasn’t announced a launch date for the Netherlands or other European countries.

Even so, the launch matters for Dutch online retailers. Google is trying to keep more of the shopping journey within its own services.

For years, consumers mainly used Google to find products. They then visited an online store to compare prices, save items and check out. With Universal Cart, Google wants to help with those next steps, too.

The move is part of a broader trend known as agentic commerce: AI systems that don’t just recommend products, but also take concrete actions during the shopping process.

Google is competing in this space with OpenAI and other technology companies developing AI assistants for online shopping.

That creates a new challenge for online retailers. Their rankings in traditional search results are no longer the only concern—they also need to know whether AI systems can find, recommend and include their products in the buying process.

Online retailers still have an important role to play, at least for now. They handle orders and customer service, and can still direct customers to check out on their own websites.

The biggest shift, then, may not be in how customers pay, but in everything that happens beforehand. Google wants to become the place where consumers collect products, compare deals and decide what to buy.
