Agentic commerce: PayPal and Google urge open protocols, crypto rails

At Consensus Miami, senior representatives from PayPal Holdings (PayPal) and Google Cloud (Alphabet's cloud unit) set out practical infrastructure requirements for agentic commerce — autonomous AI agents that discover, compare and complete purchases on behalf of users. The speakers emphasized industry-wide standards and interoperability rather than proprietary, closed solutions.

Panelists highlighted three priorities: open, interoperable payment protocols; merchant catalogs that are machine-readable; and robust multi-party custody or custody-like solutions for crypto rails. PayPal pointed to the importance of standards such as Google’s Universal Commerce Protocol for linking discovery to checkout, and its merchant research shows a material readiness gap — only around one in five merchants have 80% or more of their catalog available in structured, machine-readable form.

Market implications are already visible: payment providers, cloud platforms and crypto infrastructure firms are rapidly prototyping integrations while merchants face a practical checklist of catalog hygiene, checkout compatibility and liability frameworks. International institutions and policy papers note that both traditional rails and tokenized stablecoin rails could play roles in agentic payment flows, but both require clear identity, compliance and custody arrangements to scale safely.

In broader economic context, the shift toward agentic commerce could reshape conversion funnels, distribution and the role of marketplaces, but it also raises legal and operational questions around dispute resolution, chargebacks and responsibility when an agent makes a purchase. Industry players are therefore experimenting with hybrid custody models — combining multi-party computation, custodial services and smart-contract wallets — to balance security, compliance and user control.

Analysts say the near-term outlook depends on progress across three fronts: protocol standardization (UCP, ACP, x402 and similar efforts), wide adoption of machine-readable merchant data, and standardized custody solutions for crypto-enabled rails. If those pieces come together, agentic commerce could scale rapidly; if not, adoption will likely remain fragmented and incremental as merchants and regulators catch up.
