Mastercard’s CEO Explains the Next Big Opportunity: Machines Paying Machines

On a recent Motley Fool Conversations episode, Mastercard’s CEO Michael Miebach outlined a payments future for the company that goes well beyond its core credit card business. He described how AI shopping agents could lift transaction volume, then pivoted to the genuinely new category of machine-to-machine transactions, where companies pay each other for digital goods like compute power, APIs, and data in real time, at micro-fractions of a dollar, without invoices. For Mastercard (NYSE:MA | MA Price Prediction), a network built on card rails, that could represent both an opportunity and a major shift in the company’s business model.

AI Machines Could Create Payment Volume That Doesn’t Exist Today

Mastercard’s CEO was careful in how he presented the growth opportunities. He argued that even if AI agents eventually direct their own spending, it’s likely that consumer needs will stay somewhat fixed, meaning there would be a cap on the GDP lift driven by AI agents. However, B2B machine-to-machine payments would represent an entirely new payment volume category that does not exist today.

That framing is important because the bullish case for agentic commerce often gets sold in a simplified “AI agents doing more things means more spending,” but there’s likely some limits around how much more gets spent within the economy. The more defensible thesis is that machines transacting with machines create a payment stream that was never on any network.

Mastercard’s answer is a protocol it calls “AgentPay for Machines” (AP4M), designed to handle “always-on, high-velocity, micro fractions of a dollar kind of payments.” On the Q2 2026 earnings call, Michael Miebach put a finer point on the ecosystem, saying “Mastercard is the only network enabling machine-to-machine payments” and citing launch partners including Ant International, BVNK, Checkout.com, Cloudflare, Coinbase, and OKEx.

The BVNK Deal Pushes Mastercard Beyond Traditional Card Rails

The most striking part of the podcast was how openly Mastercard is embracing non-card rails. The CEO called BVNK “the largest stablecoin platform out there,” and said the acquisition is closing this quarter. He acknowledged the underlying infrastructure “could be stablecoin” and that Mastercard is “pretty agnostic about that.”

On the earnings call, Miebach expanded the vision, saying Mastercard expects “a world of multiplicity, many coins, many chains, and all of that needs a trusted interoperable layer… And that is what BVNK will do for us.” He was also candid that “Stablecoin isn’t the answer to everything because you still need protections, you still need acceptance, and you still need to kind of find your way into fiat.” Mastercard wants to be the trust, interoperability, and fiat on-ramp sitting above whichever rails win.

Mastercard Has the Capital to Fund a Pivot

Mastercard has the earnings power to fund this build. Q2 2026 revenue came in at $9.28 billion, up 14.07% year-over-year, with adjusted EPS of $5.04 against a $4.77 consensus. Cross-border volume rose 12%, and value-added services net revenue grew 18%.

The stock has been a laggard by its own standards, with shares at $569.29, up just 0.21% year-to-date and down 1.87% over one year, though the ten-year return is still 531.26%.

Visa Is Chasing the Same AI and Stablecoin Opportunity

Visa (NYSE:V) is chasing the same opportunity from a different angle. CEO Ryan McInerney said, “Visa, going forward, will remain multi-coin, multi-chain. Our role is not to pick winners.” Visa launched its own Visa stablecoin platform, is integrating it with Pismo for tokenized deposits, and is partnering with OpenAI to enable secure Visa payments within agentic commerce. Fiscal Q3 2026 revenue was $11.6 billion, up 14% year-over-year, with payments volume crossing $4 trillion for the first time. Visa shares are up 4.45% year-to-date at $364.15.

McInerney was blunt about the current state of stablecoins: “Stablecoins really have yet to scale beyond a few use cases like stablecoin link cards that we’ve issued in various places around the world.”

What to Watch Next

Mastercard is positioning itself to provide the trust, security, interoperability, and access to fiat that businesses and machines will need across payment rails. The BVNK acquisition and rollout of AgentPay for Machines could make the company a critical infrastructure layer for AI and stablecoin commerce.

If machine-to-machine transactions become a meaningful source of payment volume, the opportunity could drive Mastercard’s next decade of growth.
