Google announced Universal Cart at Google I/O 2026, an AI-powered shopping tool that creates a single cart across all Google services. The cart will launch this summer in the US, starting with Google Search and the Gemini app before expanding to YouTube and Gmail.

The Universal Cart uses Gemini AI models to work in the background after users add products. It monitors price drops, provides price history insights, and alerts users when out-of-stock items return. For complex purchases like custom PC builds, the cart can identify compatibility issues between components from different retailers.

“The moment you add a product to your cart, it gets to work in the background — finding deals and price drops, giving you insights on price history and alerting you when an item is back in stock,” said Vidhya Srinivasan, VP and GM of Ads and Commerce at Google.

Major retailers will support Universal Cart at launch. Nike, Sephora, Target, Ulta Beauty, Walmart, Wayfair, and select Shopify merchants have committed to the platform. The cart integrates with Google Wallet to access payment method perks and loyalty information.

Google processes more than one billion shopping interactions daily through its Shopping Graph, which contains over 60 billion product listings. The Universal Cart represents Google’s push to keep more of the shopping journey within its ecosystem rather than directing users to external retailer websites.

The tool builds on Google’s Universal Commerce Protocol, which the company describes as shared infrastructure for cross-platform shopping. Google plans to expand UCP-powered checkout to Canada and Australia, then the UK. The protocol will also come to YouTube in the US and expand to hotel booking and food delivery.

Google also previewed its Agent Payments Protocol, which enables AI agents to complete purchases on behalf of users. The system includes guardrails that require specific brand, product, and budget requirements before completing transactions.

The Universal Cart faces competition from other tech giants. Amazon has blocked outside shopping agents and sued Perplexity over automated purchasing. OpenAI partners with Stripe on its Agentic Commerce Protocol for ChatGPT checkout.

“We have been thrilled to see how the entire industry has rallied behind UCP over the last few months to help drive the agentic commerce protocol forward,” said Ashish Gupta, VP and GM of merchant shopping at Google.
