Amazon blocked Meta's shopping agent in September; a month later Walmart opened its doors to approved AI agents with spending limits. The fight is not really about the checkout; it is about who stands behind the agent when it gets things wrong.
From Piggly Wiggly in 1916 to Alipay's escrow in 2004, each leap in shopping removed a friction and needed a new trust device. Today AI agents research, recommend and fill the basket, yet they are barely buyers. China runs agent shopping inside super-apps, India builds on public rails, and the West is split between open protocols and walled gardens.
Aman Narain (Singapore; ex Standard Chartered, HSBC and Google Pay) and Zubin Vandrevala (San Francisco; your payments provocateur) break down the future of shopping in Part two of The Future Of, and answer the question that decides it: when AI agents do the buying, who pays when they get it wrong?
Key takeaways:
1. Every shopping revolution looked like a technology story and turned out to be a trust story; AI agents will be no different.
2. Amazon's stand-off with Meta's Muse is about the billboard, not the checkout: an agent never sees the ads.
3. AI is a research engine and barely a buyer today: discovery moves first, checkout follows later.
4. Know your customer becomes know your agent, and whoever underwrites the software's mistakes will own the customer.
Topics covered:
- Four frictions: distance, information, trust and attention
- Three operating systems: China, India and the West
- Amazon versus Walmart on AI agents, and the ad money at stake
- CART, the Delegation Ladder, know your agent and the Money OS
