The stablecoin fight is no longer just about crypto exchanges. Visa, Mastercard and Stripe are testing whether blockchain settlement can become payment infrastructure that the old card system still helps control.
Visa and Mastercard spent years treating stablecoins as something to watch, test and politely contain. That posture is changing. Reports around a new stablecoin platform backed by Visa, Mastercard and Stripe, with Coinbase evaluating whether to participate, show the largest payment networks are no longer content to stand aside while dollar tokens move across public blockchains.
The details are still thin, and that matters. According to a report from CoinDesk, the companies are among the backers of a soon-to-debut stablecoin platform, while Fortune separately noted that there is no formal deal yet and the conversations may still be at the consortium stage. But the direction is hard to miss. Stablecoins have become too large, too useful and too close to mainstream payments for the incumbents to leave the field to Tether, Circle, Solana Pay and a growing list of crypto-native rails.
This is not happening in isolation. Mastercard announced on June 3 that it plans to expand settlement across its network with intraday, weekend and holiday options, including on-chain settlement using regulated stablecoins. Visa said on April 29 that its stablecoin settlement pilot had reached a $7 billion annualized run rate, up 50% from the previous quarter, and now supports nine blockchains after adding Arc, Base, Canton, Polygon and Tempo to Avalanche, Ethereum, Solana and Stellar. These are no longer small lab tests. They are early attempts to wire stablecoins into the machinery of global payments.
The important part is not simply whether Visa or Mastercard launches a token. The bigger question is whether they can sit between merchants, banks, acquirers, wallets and issuers in the stablecoin economy the same way they have done in card payments. That is where the revenue is. It is also where the control is.
Stripe has already made its intentions clear through its $1.1 billion purchase of stablecoin infrastructure company Bridge. Mastercard followed in March 2026 by agreeing to acquire London-based BVNK for up to $1.8 billion, including $300 million in contingent payments. BVNK gives Mastercard a more direct connection between on-chain money movement and fiat rails, which is exactly the kind of plumbing required if stablecoins are going to serve businesses rather than just traders.
Visa has taken a more multi-chain route. Its settlement pilot now touches public chains, Ethereum scaling networks and institution-focused infrastructure. That matters because the payment world is not likely to settle on one blockchain any more than it settled on one bank. A merchant acquirer may want Base or Polygon for cost and reach, while a regulated institution may prefer Canton or another permissioned environment. Visa is trying to make those choices operationally boring.
Compliance is the advantage and the drag
The incumbents do have one obvious strength: trust from banks and regulators. A large issuer or acquirer is more likely to test stablecoin settlement through Mastercard or Visa than through a new protocol with a Discord channel and a clever dashboard. Compliance-heavy DNA can be a selling point when the customer is a bank treasurer trying to explain settlement risk to a board.
But that same DNA can slow the whole thing down. Stablecoins became powerful because they move across borders and time zones without waiting for banking hours. If a card-network stablecoin platform simply recreates the approval layers, fees and jurisdictional complexity of the old system, it will struggle to compete with crypto-native alternatives. The pitch cannot only be that stablecoins are faster. The product has to let users feel that speed in daily operations.
There is also the consortium problem. Payments companies like partnership language, but competitors do not easily share economics. Visa, Mastercard, Stripe and Coinbase each have their own incentives, customers and strategic fears. Coinbase already benefits from USDC economics through its relationship with Circle. Stripe has Bridge. Mastercard has BVNK. Visa has its own settlement network ambitions. Turning that into a shared platform will require more than a common interest in not letting Tether and Circle own the market.
USDC and USDT are still hard to dislodge
The market they are targeting is already enormous. CoinMarketCap data this week showed Tether near $187 billion in market value and USDC around $75 billion, putting the two tokens at the center of stablecoin liquidity. The broader market is above $300 billion, and its value is not just the tokens themselves. The real prize is reserve income, settlement volume, merchant adoption and the data that follows payment flows.
Still, dominance in stablecoins is not only about brand. It is about liquidity, integrations and habit. USDT remains deeply embedded in global crypto trading, particularly outside the United States. USDC has built credibility with institutions, exchanges and regulated fintechs. A new platform backed by payment giants may get distribution quickly, but it still has to prove that merchants, wallets and developers have a reason to prefer it over the stablecoins they already use.
The likely outcome is not a clean takeover. It is a more crowded market where regulated stablecoins become part of everyday settlement, and where the line between card network, crypto exchange, payment processor and token issuer becomes harder to draw. That may pressure fees. It may also make stablecoins feel less like a crypto product and more like a settlement option sitting quietly behind the checkout page.
For readers watching the fintech market, the signal is clear. Visa and Mastercard are not trying to kill stablecoins. They are trying to make sure stablecoins do not kill their relevance. The next thing to watch is whether the reported platform becomes a real product, and whether it gives businesses something crypto has promised for years: faster money movement without asking them to rebuild their entire payments stack.
