PayPal, Google Cloud: Crypto rails for agentic AI commerce

PayPal and Google Cloud executives told attendees at Consensus Miami that cryptocurrency-based payment rails will be needed for artificial intelligence agents to transact autonomously at scale.

Rich Widmann, Google Cloud’s global head of strategy for Web3, told the conference that current payment systems cannot support independent agents. “An agent can’t get a bank account. It’s not just hard; it’s impossible, due to both technological and regulatory challenges,” he said, calling crypto an “excellent machine-readable interface for payments.” He argued agents will need payment infrastructure that lets software pay for compute, APIs, digital goods and other services in real time.

May Zabaneh, PayPal’s vice president and general manager of crypto, said she expects AI agents to change commerce and urged the industry to clarify who is liable when an agent makes a poor purchase. PayPal presented survey data showing about 20% of sellers optimize product and site data for machine consumption. Executives said that lack of machine-readable catalogs limits agents’ ability to find and buy goods and services for users.

Speakers pointed to several emerging technical frameworks and product launches designed to enable agent payments. Those include the x402 standard backed by Coinbase, Google’s Universal Commerce Protocol and the Machine Payments Protocol. Amazon Web Services recently launched Bedrock AgentCore Payments with Coinbase and Stripe to support USDC stablecoins and protocols such as x402. Stripe has shown tools to simplify crypto payments and fiat-to-crypto transitions for businesses, and Block is promoting Bitcoin as a payment option for Square merchants.

Industry participants at the event estimated agentic payment use could grow into a $3 trillion to $5 trillion market by 2030. Panelists said achieving that scale will require new custody models, identity and authorization standards, and legal frameworks for liability and dispute resolution. Widmann highlighted multi-party custody and tighter links to existing capital market infrastructure as key design elements.

Analysts at the conference noted a practical bottleneck in merchants’ web catalogs. Many sites are built for human shoppers and lack the structured, machine-friendly data agents need. Presenters said merchants that adopt computer-readable catalogs receive more agent-driven referrals and higher conversion rates.

Regulatory and security concerns featured throughout the discussion. Attendees said laws governing digital assets and payment systems impose standards meant to protect users and prevent crime, which could slow everyday agentic use. Organizations including Google and Mastercard are working through the FIDO Alliance on technical rules for AI payments. Panelists warned autonomous agents handling funds could complicate fraud prevention and error correction. Zabaneh emphasized trust as her primary concern and said she would use agentic tools personally only after those issues are addressed.

The discussion reflected active development across cloud providers, payment firms and crypto companies building protocols, integrations and commercial partnerships to let autonomous software transact in an auditable way for businesses and consumers.
