Ant International Ties Up With Visa and Mastercard on AI-Agent Payments
Visa, Mastercard and Ant International are building shared rules for payments made by AI agents, covering how such transactions get verified and monitored — and who controls the rails.
Ant International, Visa and Mastercard are jointly developing common standards for payments initiated by AI agents, including methods to verify and monitor those transactions, CNBC reported on Sept. 10, 2026.
Three of the largest names in global payments are trying to agree on the plumbing before the machines start spending. Ant International has joined Visa (V) and Mastercard (MA) in an effort to develop common standards for payments initiated by artificial-intelligence agents, according to CNBC Finance. The work covers how such transactions are verified and how they are monitored once they are running.
That is a narrow-sounding remit with wide consequences. An AI agent that books travel, restocks a warehouse or renews a subscription on a user's behalf is not a cardholder tapping a phone. It has no thumbprint, no face, no physical presence at a terminal. Every assumption baked into four decades of card authentication — that a human is present, or at least directly authorising — has to be rebuilt for a piece of software acting under delegated authority.
Why verification is the hard part
The card networks already run enormous risk and fraud infrastructure. What they do not have, in a settled and interoperable form, is a way to answer three questions about a machine buyer: is this agent who it claims to be, does it actually hold authority from the person or business it says it represents, and does the purchase sit inside the limits that person set?
Verification, in the sense described in the partnership, means establishing agent identity and mandate. Monitoring means watching the transaction stream afterwards — spotting an agent that has gone off-script, been hijacked, or been spoofed by another program wearing its credentials. Both problems are unsolved at industry scale, and both are far more tractable if the largest networks agree on a shared vocabulary rather than each shipping a proprietary version.
The commercial logic is straightforward. If a merchant has to support one agent-authentication scheme from Visa, another from Mastercard, and a third from a large Asian wallet operator, agentic commerce stalls at the checkout page. Common standards remove that friction, which is exactly why competitors cooperate on rails while competing on everything built above them.
What Ant International brings to the table
Ant International is the cross-border arm of the group behind Alipay, and its inclusion signals that the standards effort is not meant to be a purely Western card-network affair. Wallet-based payment behaviour across much of Asia never ran through the card model in the first place; QR codes, super-app balances and account-to-account transfers dominate. Any standard for AI-agent payments that only works inside card rails would be partial from the day it launched.
Bringing a wallet operator with heavy cross-border volume into the design phase also addresses the currency and jurisdiction problem. An agent that buys from a merchant in another country triggers foreign exchange, local regulatory obligations and settlement questions that the human-initiated system already handles awkwardly. Doing it autonomously, at machine speed and machine frequency, makes those seams more visible.
The competitive stakes for the card networks
The threat to Visa and Mastercard from agentic commerce is not that fewer purchases happen. It is that a new layer of software sits between the buyer and the payment, and whoever owns that layer decides which rail the transaction takes. Rival AI payment protocols — some emerging from technology platforms rather than financial institutions — are aiming at precisely that position. A standard that makes card rails the natural default for agent transactions protects the networks' place in the flow; a standard written elsewhere could route around them.

There is a volume argument too. Agents that reorder consumables, monitor prices and execute purchases without prompting could raise transaction counts substantially while shrinking average ticket size. That mix shift matters for networks paid partly on volume and partly on value, and it puts pressure on fraud systems tuned to human purchase patterns. A burst of a hundred small automated purchases in an hour looks like compromise under today's rules. Under agentic commerce it may be routine.
Merchants and issuing banks are the third constituency. Chargeback liability, in particular, has no obvious home when a machine buys the wrong item. If the agent had a valid mandate and stayed inside its limits, is that the consumer's problem, the merchant's, or the agent developer's? Verification standards are the precondition for answering that; monitoring standards are how disputes get evidenced after the fact.
Where the shares stood
Markets treated the news as a long-horizon item rather than a catalyst. As of the last trade before this report, on Wednesday, Sept. 9, 2026 at 20:00 GMT, Visa closed at 367.39, down 0.34% from a previous close of 368.64, with a session range of 365.88 to 369.48. Mastercard closed at 567.50, down 0.59% from 570.89, having traded between 565.73 and 570.84.
Both moves sat inside a soft broader tape. The S&P 500 tracker (SPY) closed at $762.40, down 0.46%; the Nasdaq 100 fund (QQQ) at $716.31, off 0.29%; and the Dow tracker (DIA) at $524.07, down 0.75%. In other words, neither payments name meaningfully diverged from the market on the day — consistent with a standards initiative whose revenue implications are years out, not quarters.
What to watch from here
The first thing to look for is scope: whether the standards work stays at the level of technical specification or extends into commercial rules on liability and interchange treatment for agent-initiated transactions. The second is membership — whether banks, large merchants, and other wallet operators are brought in, and whether any of the technology platforms building competing agent protocols align with the effort or explicitly diverge from it.
The third is regulatory posture. Supervisors in the US, Europe and Asia have been circling AI accountability generally; a payment made by an autonomous agent sharpens every question about consent, record-keeping and consumer redress. An industry standard drafted early has a decent chance of becoming the reference point regulators build on. One drafted late gets rewritten from outside.
For now, the substance is modest and the signal is not. Two networks that compete for every basis point of share, and a wallet group that competes with both, have decided that the authentication layer for machine-initiated payments is worth building together. That tells you where they think the next contested ground is.

Frequently asked questions
What exactly are Visa, Mastercard and Ant International building?
They are jointly developing common standards for payments initiated by AI agents. The reported scope includes ways to verify that an agent is legitimate and authorised to transact on a user's behalf, and ways to monitor those transactions once they are flowing. It is a technical and rules-based framework rather than a single consumer product.
Why do AI-agent payments need new standards at all?
Card authentication assumes a human is present or directly approving a purchase. An AI agent has no fingerprint, face or physical card presence, and acts under delegated authority. Networks need a shared way to confirm agent identity, confirm the mandate behind it, and check that spending stays inside limits the user set.
How did Visa and Mastercard shares perform around the news?
Both eased slightly in a soft market. Visa closed at 367.39, down 0.34% from a prior close of 368.64. Mastercard closed at 567.50, down 0.59% from 570.89. Those figures are as of the last trade on Sept. 9, 2026 at 20:00 GMT, when the broader S&P 500 tracker fell 0.46%.
Why is Ant International involved rather than only the card networks?
Ant International is the cross-border arm of the group behind Alipay, and much of Asian payment behaviour runs through wallets, QR codes and account-to-account transfers instead of cards. Including a wallet operator with heavy cross-border volume makes any resulting standard workable outside card rails and across currencies and jurisdictions.
What is the competitive risk if the networks do not set the standard?
Agentic commerce inserts a software layer between the buyer and the payment. Whoever controls that layer influences which rail a transaction takes. Rival AI payment protocols, some from technology platforms rather than banks, are targeting that position. A standard written elsewhere could route volume around the established card networks.
Who bears the loss if an AI agent makes a mistaken purchase?
That is unresolved and is one reason verification and monitoring standards matter. If an agent held a valid mandate and stayed within its limits, liability could fall on the consumer, the merchant or the agent's developer. Reliable identity checks and transaction records are the precondition for settling such disputes.
