LIVE @ Google I/O: Universal Cart, Agentic Payments, and the Protocols Powering the Agent-Mediated Economy

At Google I/O 2026, Phillip sits down with Suresh Ganapathy, Senior Director of Product Management for Consumer Shopping at Google, to unpack the day's announcements: Universal Commerce Protocol's expansion into new verticals, agentic payments arriving in Gemini Spark, and the debut of Universal Cart. We trace what these foundational pieces mean for how a billion daily shoppers, and the merchants serving them, will operate in an agent-mediated economy.

Enter the Delegation Era

Key Takeaways:

• Universal Cart maintains shopper state across Search, Gemini, YouTube, and Gmail.
• The cart works on your behalf: tracking prices, flagging restocks, and catching product incompatibilities.
• Agent Payments Protocol’s (AP2) tamper-proof contracts make agent purchases verifiable and accountable to shopper intent.
• Merchants remain seller of record, preserving customer relationships inside agentic flows.
• Gemini Spark becomes Google's first consumer agent with purchasing authority this fall.
