Is Agentic Commerce the Next Consumer Revolution?
Agentic commerce is transforming how buying decisions are made, shifting influence from human consumers to autonomous AI agents that optimize for price, convenience, and personal preference. This session examines what happens when AI becomes the primary decision maker across discovery, product selection, and checkout, and the implications for merchants, retailers, and payment providers.
We explore how the retail landscape changes when agents, not people, control product and search discovery, redefining competition, visibility, and loyalty. The discussion highlights the operational and commercial shifts required for companies to stay relevant in an autonomous first world.
Takeaways
• How agentic commerce changes consumer behavior and the path to purchase
• What merchants, PSPs, and retailers must rethink as AI agents take over discovery, choice, and checkout
• The new risks and opportunities created when autonomous agents transact on behalf of customers
