Visa Says Stablecoins Will Power AI Agent Microcommerce

On July 16, 2026, Visa and blockchain analytics company Artemis released a joint report titled “Agentic Payments from the Ground Up.” The document states that stablecoins will become the preferred payment rail for AI agents for micropayments, while bank cards will remain dominant for traditional purchases. This announcement is of particular importance as it could redefine the financial infrastructures of tomorrow.

Visa report highlights stablecoins

The report published by Visa distinguishes two categories of purchases made by AI agents :

• Macrocommerce: it brings together tasks entrusted by a human to an AI (booking a flight or managing a subscription) with amounts close to traditional online commerce.
• Microcommerce: it concerns automated and recurring payments, often less than the dollar, exchanged directly between software (API call, purchase of computing power, access to a database, etc.).

It is on this second segment that Visa focuses its analysis. The reason is that fixed bank card fees make these transactions unprofitable on a large scale. Stablecoins offer settlement costs reduced to a fraction of a cent on recent blockchains. They thus become the natural crypto alternative to finance these invisible but massive flows.

Why are stablecoins taking over in AI agent crypto microcommerce?

The idea of ​​making the web pay for use is not new. As early as 1997, the HTTP 402 code had been reserved for future online payment systemnever materialized due to lack of suitable rails. According to Visa, what is changing today is the conjunction of two factors:

• AI agents now capable of spending autonomously;
• a new generation of blockchains inexpensive enough to make payments between a penny and a dollar viable.

THE stablecoins check exactly this box where bank cards fail structurally. Combined with account abstraction and sponsored transactions, they allow these crypto rails to run in the background, without the end user ever having to worry about it.

Crypto protocols that validate the use of stablecoins by AI agents

THE report is based on two already operational protocols.

• x402incubated by Coinbase and Cloudflare and then taken over by the Linux Foundation, has processed approximately $15 million in stablecoins across 109.6 million transactions since its launch in May 2025, primarily on Base, Solana and Polygon.
• THE Machine Payments Protocol (MPP)developed by Stripe and Tempo with contribution from Visa, displays more modest volumes — around $25,000 across 115,000 transactions since mid-March 2026. However, its bipartite architecture and ability to support multiple settlement rails make it a crypto protocol to watch closely.

On both platforms, the average payment does not exceed a few fractions of a cent. A scale at which no traditional banking rail can operate profitably!

Cards and stablecoins, the crypto convergence orchestrated by Visa

Visa states this bluntly in its report:

It won’t come down to choosing between cards and stablecoins. Both will have their place.

Moreover, the group is already anticipating a hybrid model where the cards would manage authentication and general public purchases within existing merchant networks, while stablecoins would ensure real-time settlement between AI agents.

Protocols historically linked to cards, such as the Trusted Agent Protocol or Visa Intelligent Commerce, already integrate native support for stablecoins, while native crypto protocols borrow trust mechanisms from the banking world.

This convergence is part of a broader strategy. We are referring to Visa which has joined Mastercard, Stripe, Coinbase and BlackRock within the OUSD consortium. This is a stablecoin intended for business-to-business payments.

A major obstacle remains: the current legal framework

It relies on the assumption that a human is making the purchase and can vouch for it. When an AI agent acts alone, there is no clear rule determining who is responsible in the event of an error:

• the user who delegated the task
• the platform that hosts the agent
• the model editor
• the merchant.

Chargeback procedures, designed for human-paced commerce, are therefore not designed for chains of AI agents capable of executing thousands of transactions per hour. Visa explicitly recognizes that no clear framework yet exists to resolve these disputes in the crypto world of automated stablecoin payments.

In any case, Visa has just made a shift: the AI ​​economy will not be built without crypto rails adapted to its speed and scale. It remains to be seen whether law will keep pace with technology!
