Verified facts
- Products from several merchants appear in a common Search and Gemini cart, with price-drop and back-in-stock alerts.
- Google Wallet helps select a payment method and the cart shows promo codes; checkout uses Google Pay or the merchant site.
- The merchant remains the seller of record, responsible for confirmations and support. The cart uses Universal Commerce Protocol.
What changes
Shopping can start in an assistant without the merchant disappearing.
Practical implication
Compare final price, delivery and merchant before paying.
Availability
Belgium/EEA: this October 15 rollout concerns the United States; the announcement establishes no Belgian availability.
Limits and uncertainty
Google explicitly distinguishes this user-controlled cart from agentic capabilities that act on the user’s behalf. This is not an announcement of universal autonomous purchasing.
