Card Networks and Coinbase Circle a New Stablecoin Platform

A reported plan involving Stripe, Visa and Mastercard points to a new phase in the stablecoin market: big payments companies are no longer treating tokenized dollars as an experimental side project. According to CoinDesk, the three firms are close to introducing a stablecoin platform, and Coinbase is also evaluating whether to participate. Even without formal confirmation from the companies involved, the shape of the story matters. It suggests that the sector’s largest consumer and merchant networks increasingly see stablecoins as infrastructure that could sit inside mainstream payment flows rather than outside them.

The timing is notable because the article places the discussions against a market that has already reached institutional scale. CoinDesk says stablecoins now represent roughly $325 billion in market capitalization, with Tether’s USDT accounting for about $115 billion of that total. That scale helps explain why card networks and payment processors are pushing deeper into the category. For these firms, stablecoins are no longer just crypto trading instruments; they are becoming settlement assets, treasury tools and programmable payment rails that can operate across weekends, holidays and multiple blockchain networks.

Each of the companies named in the report has been building toward this point from a different angle. Stripe bought stablecoin infrastructure company Bridge in late 2024 for $1.1 billion, giving it a more direct position in the software and orchestration layer around digital-dollar payments. Visa has been expanding its stablecoin settlement pilot, adding Base, Polygon, Canton Network, Arc and Tempo to earlier support for Ethereum, Solana, Avalanche and Stellar. Mastercard, meanwhile, has been widening its own stablecoin settlement effort and recently added more focus to always-on transaction flows. Taken together, those moves make the idea of a shared platform look less like a surprise and more like the next logical step.

Coinbase’s reported interest adds another layer because the exchange already sits close to the economics of dollar-denominated crypto payments. CoinDesk notes that Coinbase launched a white-label stablecoin service and Coinbase Business for stablecoin payments late last year. It also highlights Coinbase’s revenue-sharing arrangement with Circle, under which the exchange keeps the interest income generated by USDC held on-platform and splits off-platform ecosystem revenue. If Coinbase were to join a broader stablecoin platform backed by payment incumbents, it would bring both distribution reach and direct experience operating around reserve-backed digital dollars.

For RWA and tokenized-finance builders, the deeper signal is that market structure is shifting from isolated pilots to interoperable service layers. A platform backed by card networks, a payments processor and potentially a major exchange would not just move stablecoins faster; it could also standardize onboarding, treasury movement, merchant acceptance and cross-network settlement. That matters for tokenized funds, onchain cash management and any product that depends on reliable digital-dollar liquidity moving between traditional institutions and blockchain-native venues. The more these firms converge on shared rails, the easier it becomes for other tokenized assets to plug into mainstream financial workflows.

There is still a meaningful gap between reported planning and a launched product, and the companies involved were either declining comment or had not responded at publication time. Still, the direction is clear. Stablecoin competition is moving beyond issuer market share and into platform control, distribution partnerships and settlement standards. If this reported consortium materializes, it would mark another step in the steady conversion of stablecoins from a crypto-native instrument into core payment infrastructure for the broader financial system.
