Visa: Stablecoins to Drive the Emerging AI Economy

Visa identifies stablecoins as the essential infrastructure for AI agents, handling high-frequency micro-payments that traditional card networks cannot.

The company indicated that stablecoins are poised to become the primary payment infrastructure for “micro-commerce,” while traditional card networks will continue to serve larger consumer payments.

Visa Sees Stablecoins as the Foundation of the AI Economy

Visa has warned that existing global card payment infrastructure was not designed to serve the new generation of autonomous AI agents. These agents are expected to perform a massive volume of small, real-time transactions. In a joint analysis with the investment platform Artemis, the company highlighted the rising importance of “micro-commerce”—an economy where software agents purchase digital services without human intervention.

According to Visa, traditional card networks are optimized for a relatively limited number of higher-value payments. Fixed fees and the inherent structure of card settlements make transactions under one dollar economically inefficient. This creates a significant hurdle for the future development of autonomous AI systems.

The company expects AI agents to increasingly handle automated payments for API access, database queries, cloud computing, and other digital resources. In this environment, individual operations may be valued at only a few cents each.

A Hybrid Model Between Cards and Blockchain

Visa believes that stablecoins offer the most suitable infrastructure for these machine-to-machine payments due to lower costs and near-instant settlement. Rather than replacing card systems, digital assets will complement existing payment structures.

The company outlined a model where traditional card networks continue to facilitate consumer-initiated purchases—such as subscriptions or larger online payments—while stablecoins take over high-frequency micro-payments between autonomous AI agents.

The analysis highlights two technologies already building this infrastructure. The x402 protocol, developed with participation from Coinbase and Cloudflare, has processed approximately $15 million through over 109 million individual transactions since its launch in May 2025. Another platform, the Machine Payments Protocol (MPP), being developed by Stripe and Tempo with Visa’s involvement, aims to bridge blockchain payments and traditional financial infrastructure through a common settlement standard.

This initiative is part of Visa’s broader strategy to develop “Agentic Commerce”—an environment where autonomous AI systems can independently purchase services, execute payments, and interact with various digital platforms.

During the Visa Payments Forum 2026, the company introduced several new solutions targeting this transformation. These include the Agentic Directory, a system for authenticating legitimate AI agents; Agent Score, a tool to assess merchant readiness for autonomous systems; and the “Large Transaction Model,” a fraud detection model specifically designed for the high-frequency operations of AI agents.

Visa also reported that as of March 2026, it is processing stablecoin payments at an annual rate of approximately $7 billion. The company views this as evidence that digital assets are steadily becoming part of the global payment infrastructure. Instead of a conflict between traditional cards and blockchain technology, Visa is betting on a scenario where both models operate in parallel, serving different transaction types in the future AI economy.
