Visa, Mastercard Unlock AI Spending In $5T Agentic Push

Imagine a piece of software that doesn’t just schedule your week but pays for it. You tell your AI agent you need to be in Austin next Tuesday. It books the flight, reserves a hotel near your client’s office, handles a canceled flight by instantly rebooking you and reserving a rental car, orders dinner to your room upon arrival, and even files the expense report, all without a single manual login or approval click beyond your initial command.

This is agentic commerce, a projected $3 trillion to $5 trillion global market by 2030 according to McKinsey. Right now, it’s a promise stuck in financial mud. The AI agents that could execute these tasks can’t easily transact across closed banking systems, navigate disparate loyalty programs, or prove who authorized them without human intervention.

That’s why an announcement on Tuesday, August 18, carries weight. Stablecoin payments infrastructure company Rain revealed it has formed the Agentic Payments Alliance (APA), a coalition to build the financial plumbing for this autonomous future. The headline is the founding roster: Visa, Mastercard, Fiserv, Circle, Solana, and Remitly, along with over 20 others including Chainalysis, Fireblocks, and Uniswap Labs, according to PYMNTS. It’s a rare pre-emptive alignment of traditional finance rails and crypto-native infrastructure, aiming to set the rules before the market fractures into corporate silos.

Someone Needs To Pay The Robot

The term "agentic" is moving beyond automation buzzwords. It refers to AI software acting with delegated authority to execute complex, multi-step tasks that require payments. This isn’t a simple script or a chatbot. It’s an autonomous entity that can make decisions and commit value on your behalf.

Consider a real-time disruption. Your flight is canceled.

A true agent wouldn’t just send you an alert. It would assess your calendar and preferences, find and book a viable alternative flight, negotiate any refund from the airline, pay for the new ticket using your preferred payment method, update your ground transportation, and log the transaction for expense reporting. It’s a seamless, atomic sequence of actions across multiple platforms.

Today, this is impossible. No agent can easily pull from your corporate card balance, interact with an airline’s booking system, and update your internal accounting software in one go. Payments are trapped in app-specific wallets, behind single-bank APIs, or restricted by geography, highlighting challenges that innovators like Cash App are simplifying for consumers in other areas of digital finance. The missing layer is a universal financial language and set of protocols for non-human actors. This challenge mirrors the infrastructure gaps seen as traditional finance evolves, as we explored in our analysis of Top Banks Prioritize Tokenized Deposits Over New Stablecoins.

Why Visa, Mastercard, and Solana Are In The Same Room

The APA’s stated mission is to "bring the people building that infrastructure into the same conversation, before those decisions get made in isolation." This is a standards play, and the coalition’s composition reveals the probable technical blueprint.

Visa and Mastercard aren’t there to build the AI agents. They are the incumbent, globally-interoperable settlement networks. Their role is to provide the trusted "highway system" over which agent-driven transactions can flow securely at scale. "Agentic commerce is a when, not an if," Visa CEO Ryan McInerney said recently.

The inclusion of Circle, issuer of the USDC stablecoin, and the Solana blockchain points to how these transactions might actually settle. For speed, programmability, and 24/7 operation, settling agent payments on-chain using stablecoins is a leading candidate. The presence of Fiserv, a major merchant acquirer, and Remitly, focused on cross-border flows, shows the coalition intends to span the entire value chain, from the consumer agent to the merchant’s bank account to international settlements.

“No single company should get to decide how agents transact on someone's behalf. That has to come from the platforms building the rails, the regulators setting the rules, and the innovators closest to how agents are actually being used today,” said Farooq Malik, Rain's CEO.

The alliance plans to conduct shared research, develop technical frameworks, test standards for AI agent identity and authorization, and engage on regulatory issues. Founding members will also get early access to Rain's Agentic Startup Program, an accelerator for early-stage companies building in this space.

The Sticking Points: Liability, Limits, and Control

Moving from vision to viable system requires solving thorny problems the APA will have to navigate.

Trust and Guardrails How do you ensure an agent acts in your best interest? The potential for misuse or poor decision-making is high. Rain’s own offerings hint at solutions: its Agent Control Layer and Scoped Cards are designed to give agents "widely accepted payment credentials that are safe and limited." The key will be standardized ways to set spending limits, define agent permissions, and audit their activity, a level of financial control not yet common.

The Regulatory Gray Zone Current financial regulation is built around human actors. Who is liable if an AI agent makes an erroneous or fraudulent transaction? How do Know Your Customer (KYC) and anti-money laundering rules apply when software is initiating payments? Regulators will need new frameworks, and the APA’s advocacy work will be critical in shaping them.

Openness vs. Entrenchment The coalition claims it is "run collectively by its founding members rather than owned by any one company." The test will be whether the standards it develops are truly neutral and open, or whether they ultimately favor the business models of the largest incumbents. The risk, as Mastercard's Sherri Haymond noted, is that "innovation outpaces alignment," leading to a fragmented, insecure landscape. True success means building rails anyone can use, a strategy for ecosystem growth familiar from global expansion plays, similar to how companies structure initiatives like Ebanx Plants Executives in Foreign Markets for Growth.

The formation of the Agentic Payments Alliance is a clear signal. Major financial players see the agent-driven economy coming and are choosing to try to build its foundation together, now. The next steps, their first published frameworks, their engagement with regulators, and the success of the startups they incubate, will show whether this alliance can build the open highways this new economy needs, or if it merely paves the road for tomorrow’s walled gardens.

The Stakes

• It addresses the current $3-5 trillion agentic commerce market that's stuck due to incompatible financial systems.
• It prevents a fragmented future by aligning major payment networks (Visa, Mastercard) with crypto infrastructure (Solana, Circle) early.
• It enables truly autonomous AI agents that can handle complex real-world tasks like travel disruptions, changing how consumers and businesses operate.
