By Visa reported fiscal fourth-quarter net revenue of $12.1 billion on Tuesday evening, up 13%. It told investors that stablecoin settlement had passed a $25 billion annualized run rate, roughly ten times the level a year earlier. Eight days before that, the company put its first live agentic payments pilot into production with BILL and Billtrust.
That pilot pays nothing a human has not already approved, which is the whole state of agentic payments right now. The reason sits in the fraud engine between an AI agent and a merchant, where a decade of bot defenses meets software that behaves exactly like a bot.
Visa’s $25 Billion Run Rate Lands Eight Days After Its First Agent Pilot
In the 20 October pilot, an authorized BILL Payment Agent registers through Visa’s Trusted Agent Protocol and Agentic Directory, then settles invoices with tokenized credentials inside a buyer’s approved payment instruction. Billtrust authenticates it and grants portal access. Visa says this replaces what “CAPTCHA and bot-blocking tools historically provided,” without a separate agent login, which is the bot-detection problem agentic payments run into. Mark Nelsen, Visa’s head of product for commercial and money movement, said businesses should not have to choose between automation and control.
Visa closed at $404.16 on Tuesday and traded at $401.30 on Wednesday, down 0.71%. The protocol is not new, having shipped inside Intelligent Commerce Connect in April. What changed on 20 October is that money moved through it between two real platforms, the first agentic payments flow in commercial use.

Lev Brodsky, CTO of FinteqHub, a Vilnius payment orchestration platform that routes merchants across more than 200 providers in 150 countries, argues that detection, not willingness, holds agentic payments back.
“A purchase made at 3:00 AM from a cloud server’s IP address, lacking the typical signs of human interaction with a website, might appear suspicious; yet, for an AI agent executing a task on behalf of its owner, this is a perfectly routine action. This creates a paradox: technologies developed over years to protect payments from automated attacks now potentially hinder the growth of agentic commerce.”
That paradox costs money already, with no agent in the flow at all. PYMNTS found in March that 47% of merchants lose sales to false declines, with nearly half estimating up to 5% of legitimate orders are wrongly rejected, against roughly $50 billion of industry revenue.

Visa’s stablecoin settlement run rate of $25 billion is roughly ten times a year earlier, while its first live agentic payments pilot still requires a human to approve each invoice.
Mastercard Put Skyfire’s Know Your Agent Into Agent Pay on 30 September
Mastercard announced the infrastructure Brodsky calls for four weeks before he described it. Its 30 September expansion of Agent Pay added a probability score rating how likely an AI agent initiated a transaction, shared intelligence signals for issuers and merchants, Cloudflare on privacy-preserving signal environments, and Skyfire’s Know Your Agent technology for agent identity.
“Payment infrastructure must be capable of identifying an AI agent and verifying its authorization. Such authorization must be both verifiable and revocable, with every transaction strictly adhering to predefined limits.”
That is a specification for agentic payments, and Mastercard’s probability score is one attempt at the first half of it. Both networks shipped agentic payments infrastructure in the same Las Vegas conference week, Mastercard also launching a stablecoin risk tool that screens transactions before funds move on-chain on 19 October, a day before the Visa pilot.
x402, USDC and Why Agentic Payments Favor the Stablecoin Rail
Mastercard built Agent Pay on x402, the Coinbase protocol that revives the HTTP 402 status code so an agent hitting a paywall attaches a signed USDC payment and retries the request. Jorn Lambert, Mastercard’s head of product, told Fortune on 26 October that “what we’re witnessing is a bit of a turning point,” driven by consumer agents rather than the machine-to-machine protocols the industry expected. Both networks have sat inside the x402 Foundation since it launched in July with 40 members, and FinanceFeeds forecast in April, in its breakdown of crypto’s agentic stack, that one of them would integrate the protocol before year-end.
Visa’s own joint report with Artemis splits the two rails by transaction economics, arguing cards keep consumer purchases while stablecoins take the sub-dollar machine payments that fixed card fees price out. Allium data through September shows stablecoin supply up just 0.4% for the year at $305 billion while payment value rose 45% to $482 billion and payment count rose 71% past one billion. Stablecoin-linked card spend hit $3.9 billion, about ten times the prior year. On x402 the payments are smaller again, with 8.7 million transfers in the week of 17 August against $367,950 of volume, roughly four cents each. A fraud system that wrongly rejects a four-cent API call does not cost a sale. It breaks the rail.

Brodsky reads the Visa pilot as progress with a ceiling, saying it “remains a far cry from full-fledged agentic commerce, where an AI could independently select a vendor, negotiate terms, and complete a purchase.” Until Know Your Agent infrastructure is widely adopted, he expects agentic payments to stay inside scenarios that need prior human approval, and nothing shipped so far contradicts him.
Mastercard projects one in ten consumers routinely using agents to purchase by 2030. RippleX head of engineering Ayo Akinyele expects XRP Ledger agentic transactions to reach 100 million within two years from about one million. Neither number arrives while every payment waits on a person, and no current law settles who is liable when an agent buys on its own.
Investor Takeaway
Agentic payments already have the Know Your Agent layer Brodsky calls the industry’s next step, built into Mastercard’s Agent Pay through a Skyfire partnership announced on 30 September. The open question is whether agentic payments clear fraud systems with it.
