Google started rolling out Universal Cart in the US on October 15: one cart across retailers, inside Search and the Gemini app. It tracks price drops and restocks, applies promo codes, and suggests which card in your Google Wallet earns the most on each purchase [Google, via The Next Web]. Nike, Target, Walmart, Sephora and Shopify sellers are among the merchants checking out through it. Google is turning its AI assistant into a place where buying gets done, and shoppers are ready to start with the everyday basket. Groceries top the list of purchases consumers would hand to an AI agent, at 41% [ Agentic Commerce 2026]. Shopping is one vertical. Fitness, productivity and the rest of everyday life follow, each best served by a specialized agent holding the context you choose to share. That's the Gotchi model, with CHI as the shared access, rewards and commerce layer. 🦖
