Autonomous AI agent economy faces infrastructure gaps: Visa, Artemis

Infrastructure Bottlenecks Limit Autonomous AI Agent Economy Adoption

Visa and Artemis found that infrastructure bottlenecks are preventing broader commercial adoption of the autonomous AI agent economy.

Emerging Payment Standards

Some agentic payment standards are already showing signs of user adoption, such as the x402 payment protocol developed by Coinbase. The x402 processed $15 million in adjusted volume across over 109 million adjusted transactions since it was launched in May 2025.

It saw a sharp acceleration in October 2025, when the monthly transaction count rose from 40,000 to 3.8 million, leading to 38 million transactions processed in October alone.

A Unified Machine-Payments Framework

A single machine-payments framework could support both stablecoin and traditional card transactions, Visa and Artemis said, adding:

"The trajectory points toward convergence rather than competition: cards for proxy purchases inside existing merchant networks, stablecoins for machine-native micropayments, and hybrid flows where both are used within the same workflow."

The report said that a single machine payment framework can support both stablecoin-based flows and card transactions, creating a path into agentic payment flows for card networks. It added that Tempo’s Machine Payment Protocol (MPP) now spans both onchain crypto payments and fiat payments via shared payment tokens.

Visa said its Card Specification SDK was designed to extend the protocol into card-based agent commerce.

Recent AI Payment Tool Launches

Visa’s crypto division and Stripe-backed Tempo both launched AI tools in March:

• Visa’s allows AI agents to make same-day payments.
• Tempo debuted its Machine Payments Protocol, designed to make it easier for AI actors to send and receive money.
