When stablecoins first gathered momentum, the easy narrative was that they would disintermediate the card networks — cut Visa and Mastercard out of the flow of money. The two companies have spent 2026 making sure that doesn’t happen, and their strategy is refreshingly blunt: don’t pick a winner, become infrastructure for all of them.
The clearest example is Arc, an enterprise blockchain initiative led by Circle, the issuer of USDC. Visa and Mastercard have both joined, alongside Global Payments and MoneyGram. Arc bills itself as an “operating system for the internet” of money, aimed at financial markets, real-time payments, and agentic commerce. Visa CEO Ryan McInerney has summed up the posture in four words: “multi-coin, multi-chain.” The networks aren’t wagering on a single token — they’re positioning to route across all of them.
Buying the picks and shovels
The card networks have backed the strategy with acquisitions. Mastercard has moved to fold in stablecoin infrastructure provider BVNK to build out global stablecoin capabilities for its partner programs. Visa, meanwhile, has picked up behavioral-biometrics fraud firm BioCatch, layering fraud defense on top of its expanding stablecoin and AI initiatives. The pattern is consistent: acquire the plumbing, then offer it to banks and fintechs as a service.
Why “neutral infrastructure” is the smart bet
There’s a reason both networks are converging on the same playbook. Nobody knows which stablecoins or chains will dominate three years out — and that uncertainty is precisely the opportunity. By staying neutral, Visa and Mastercard turn a potential existential threat into a new product line. Whether a payment settles in USDC on one chain or a bank-issued token on another, the networks want to own the fraud scoring, the compliance, the dispute handling, and the merchant relationship around it.
It’s a familiar move for two companies that have survived every payments revolution so far by making themselves indispensable to whatever comes next. For merchants, the reassuring read is that stablecoin acceptance will likely arrive wrapped in the same fraud tools and settlement guarantees they already rely on — just with new rails underneath.
