[Video interview] Agentic commerce: liability, use cases, and the future of payment costs

In this interview, we delve into how agentic commerce could impact traditional payment flows and card acceptance fees. Initially, consumers will continue to pay as usual, but over time, AI agents representing both buyers and sellers will negotiate not only product terms but payment methods. This could shift transactions from card networks to more cost-effective channels such as account-to-account (A2A) transfers or stablecoins, potentially reducing merchant processing costs.

A key challenge in agentic commerce is liability – particularly when an AI agent makes a purchase without explicit consumer authorisation. If an agent assumes budget flexibility that wasn't granted, the current system could leave the merchant responsible for a transaction the consumer never intended. In such cases, the agent has failed to meet the user-defined criteria, raising questions about consent and accountability.

Any deviation from the parameters set by the consumer introduces ambiguity. While networks like Visa have announced intentions to position themselves as intermediaries – verifying whether all criteria were met – they lack access to critical item-level data, such as SKUs. With visibility limited to the total transaction amount and a few metadata fields, they may not be well-positioned to adjudicate disputes or verify agent compliance in real time.
