Visa Gave AI Agents Access to 175 Million Merchants. The Law Governing What Happens When One Overspends Was Written in 1978.

On June 10, Visa announced that AI agents can now initiate purchases at any of its 175 million merchant locations — and Mastercard launched a competing agent payment system the same day with a fundamentally different architecture. The race to own AI commerce infrastructure is already underway. The legal question neither company has resolved: when an agent buys something the consumer didn't intend, does Visa's zero-liability guarantee apply? The Electronic Funds Transfer Act's 'unauthorized transfer' definition, written in 1978, has not been adjudicated for the scenario where a consumer authorized the agent but not the specific purchase.

On June 10, 2026, Visa announced that AI agents can now complete purchases at any of its 175 million merchant locations worldwide. The announcement introduced three infrastructure components: Agent Score (a merchant readiness evaluation tool that assesses whether an AI agent can navigate a merchant's checkout), the Agentic Directory (a two-sided registry of agents and merchants), and the Large Transaction Model (a fraud detection system purpose-built for agent-initiated purchases). The technical mechanism is an MCP Server API that enables direct LLM-to-payment-network connectivity.

Separately, on the same day, Mastercard launched Agent Pay for Machines (AP4M) with 31 partners including Stripe, Adyen, Coinbase, and Cloudflare. Coverage of June 10 focused almost entirely on Visa-OpenAI.

What the coverage missed: the Mastercard architecture is fundamentally different.

Visa's model extends consumer accounts through delegated authorization: a human cardholder grants an AI agent permission to transact on their behalf, with the agent using tokenized credentials derived from the consumer's card. Every agent purchase routes through an existing cardholder account.

Mastercard's AP4M uses blockchain-based agent identity — agent credentials stored on Polygon, Solana, and Base. Agents can hold their own payment identities independent of any human's account, enabling machine-to-machine commerce: software licensing, per-API-call payments, real-time data marketplace transactions at sub-cent scale and machine speed. Mastercard CPO Jorn Lambert: "Machine payments can make it possible for services to be bought and sold among agents at fundamentally different scales."

These are two bets on what AI commerce will primarily be: agents acting on behalf of human shoppers (Visa's model), or autonomous software systems transacting with each other (Mastercard's model). Both will likely exist. Which architecture governs the larger share of AI-economy payment volume is not a settled question.

This is not Visa's first AI integration.

The June 10 announcement was framed widely as the first time a major payment network plugged into AI at scale. It was not. Visa launched Intelligent Commerce in April 2025 with eight AI partners — Anthropic, IBM, Microsoft, Mistral AI, OpenAI, Perplexity, Stripe, and Samsung. Production pilots with named retailers ran in late 2025. The June 10 announcement is a scale expansion and infrastructure formalization, not an inaugural event.

The OpenAI integration is also not exclusive. Visa Intelligent Commerce is a multi-platform product. Claude-based agents are covered through Anthropic's April 2025 partnership. The Visa-OpenAI press release names "ChatGPT and Codex experiences" specifically, but the underlying infrastructure is available to any partner with MCP integration.

The authorization gap.

Visa's consumer control model allows users to pre-configure spending limits and merchant category restrictions. These controls are issuer-configurable — banks that participate in the Visa Agentic Ready program set the parameters, not Visa centrally. No universal default limit applies across all issuing banks.

Visa asserts that its zero-liability guarantee covers unauthorized agent-initiated charges. The unresolved question is what "unauthorized" means when a consumer granted the agent access.

The Electronic Funds Transfer Act, enacted in 1978, defines an "unauthorized electronic fund transfer" as one initiated by a person "other than the consumer" without actual authority. Whether a consumer who grants an AI agent broad shopping permissions, then disputes a specific purchase the agent made within that scope, qualifies as "unauthorized" under Regulation E has not been adjudicated. The consumer gave the agent authority — just not unlimited authority. Whether scope overage constitutes an unauthorized transfer is the gap.

Fenwick & West's legal analysis of this question found no binding precedent. If a consumer provides an "access device" to an agent, EFTA's liability protections may not cover agent actions that exceed intended scope — because the consumer authorized the access, even if not the transaction. A January 2026 CFPB advisory framed agent-initiated transactions as within existing dispute-and-chargeback regimes, stating that the consumer's right of recourse is "not extinguished by the existence of the agent mandate, only narrowed where the mandate is appropriately scoped." That advisory came from a single secondary source (Fenwick) and has not been confirmed via direct CFPB documentation.

The practical scenario: a consumer enables a general shopping agent, the agent purchases a $2,000 item outside intended scope, the consumer disputes it. Whether Visa's zero-liability applies is, as of June 2026, a question no court or regulator has definitively answered.

The mandate-metadata gap.

Visa's infrastructure includes cryptographically signed mandate records — agent identity, scope, consent timestamp, originating device — that can be attached to transactions. Transactions with this metadata track near human-initiated dispute rates. Transactions without it run at materially higher dispute rates, according to a single-source industry report (TrustSphere.ai, Q1 2026 — not independently verified). As of June 2026, mandate recording is infrastructure Visa is building, not universally implemented. The gap between when agents start transacting and when mandate metadata is universal represents a window of elevated dispute and fraud risk.

Visa's own threat data: a 450% increase in dark web posts mentioning "AI Agent" over six months through June 2025, and a 40% increase in malicious bot-initiated transactions in the US over the same period. This data was published at the Visa Payments Forum on June 10 — the same event where Visa launched its AI agent payment product.

Who isn't here.

Stripe is present in both the Visa and Mastercard ecosystems. PayPal — which processed $1.7 trillion in 2025 payments volume — is absent from both major agent payment announcements as of June 2026. American Express and PayPal both appear in Google's AP2 coordination protocol (launched September 2025) but have no standalone agent payment infrastructure announcement. PayPal's absence from the two dominant June 10 launches is either a strategic bet that agent transactions will route through existing merchant integrations, or a competitive gap that will close in the next 12 months.

The regulatory framework for who is responsible when a machine makes a financial mistake at machine speed is not yet written.
