Visa, Mastercard, and Stripe have collectively deployed more than $3 billion in acquisitions and committed infrastructure to embed stablecoin settlement into traditional card rails. Visa's stablecoin settlement pilot hit a $7 billion annualized run rate in April 2026, up 50% quarter-over-quarter, operating across nine blockchains and more than 130 card programs in over 50 countries. Mastercard followed on June 3 by opening its global settlement network to regulated stablecoins across eight chains, weeks after announcing its $1.8 billion acquisition of BVNK, a London-based stablecoin infrastructure firm.
The three largest Western payment processors now treat on-chain dollars as a settlement medium rather than a speculative asset class. Adjusted stablecoin transaction volume reached $10.9 trillion in 2025, according to Chainalysis — within striking distance of Visa's $14.2 trillion in annual card volume. Stablecoin-linked card spend alone grew 319% year-over-year in 2025 to approximately $5.2 billion. The economic question is no longer whether stablecoins integrate with legacy rails, but who captures the settlement margin.
Visa announced on April 29 that its stablecoin settlement pilot had reached a $7 billion annualized run rate, up from $4.6 billion the prior quarter. The network added five blockchains — Arc, Base, Canton, Polygon, and Tempo — to its existing support for Avalanche, Ethereum, Solana, and Stellar, bringing the total to nine.
The pilot underpins more than 130 stablecoin-linked card programs across 50+ countries, with live regional rollouts in Latin America, Europe, Asia-Pacific, and the CEMEA region. Visa carries more than 90% of on-chain crypto card volume according to Insights4VC analysis, despite both Visa and Mastercard supporting comparable numbers of card programs.
Rubail Birwadker, Visa's Global Head of Growth Products, stated: "Visa is expanding stablecoin settlement because our banking partners are not only asking about it — they're preparing to use it."
Two issuers illustrate the scale trajectory. Rain, a crypto-native card issuer with direct Visa membership, reported approximately 38x growth in 2025, reaching over $3 billion in annualized volume. Reap, focused on corporate spend, exceeded $6 billion annualized. These figures remain small relative to Visa's $14.2 trillion in total 2025 payment volume, but the growth rate — 460% year-over-year for Visa's stablecoin card spend — outpaces every other card category.
The settlement model works as follows: qualifying Principal Members settle directly with Visa in supported stablecoins (primarily USDC). Visa's digital custodian then converts to fiat for merchant payouts. This reduces settlement friction for crypto-native issuers that would otherwise need to pre-fund fiat accounts across multiple jurisdictions.
Mastercard's stablecoin strategy moved from pilots to committed infrastructure in Q1–Q2 2026 through two actions.
First, in March, Mastercard announced the acquisition of BVNK, a London-based stablecoin infrastructure firm, for up to $1.8 billion (including $300 million in contingent performance payments). The deal, expected to close by year-end, gives Mastercard access to BVNK's network of stablecoin stakeholders, liquidity providers, and — according to CEO Michael Miebach on the Q1 earnings call — "a portfolio of hard-to-get licenses." This marked the first time a major publicly listed traditional payments firm used M&A to enter the stablecoin infrastructure market directly.
Second, on June 3, Mastercard expanded its settlement capabilities to support regulated stablecoins across eight blockchain networks: Arbitrum, Base, Canton, Ethereum, Polygon, Solana, Tempo, and the XRP Ledger. Supported stablecoins include Circle's USDC, Paxos-issued PYUSD, USDG, and USDP, Ripple's RLUSD, and SoFi's SoFiUSD.
Five early adopters — ARQ (formerly DolarApp), CBW Bank, Cross River, Lead Bank, and Nuvei — will implement stablecoin settlement in the United States and Latin America, with broader geographic expansion planned through 2026.
The settlement enhancement extends beyond stablecoins: Mastercard simultaneously introduced intraday, weekend, and holiday settlement windows in fiat, moving toward a 24/7 always-on model. The stablecoin option exists as one rail among several, a design that embeds blockchain settlement into existing compliance and reporting frameworks rather than creating a parallel system.
Mastercard has not disclosed stablecoin settlement volumes comparable to Visa's $7 billion figure, suggesting early-stage adoption. However, the BVNK acquisition signals the company views stablecoin infrastructure as a capital-allocation priority: $1.8 billion is Mastercard's largest fintech acquisition in recent years.
Stripe completed its $1.1 billion acquisition of Bridge in early 2025, giving it end-to-end stablecoin infrastructure: issuance, compliance, reserve management, and cross-border movement. Bridge's payment volumes quadrupled in 2025, according to Stripe.
In February 2026, Bridge received a conditional national trust bank charter from the OCC, providing federal oversight for stablecoin issuance and digital asset custody. This regulatory milestone positions Stripe/Bridge as both a technology provider and a regulated financial institution — a dual status that neither Visa nor Mastercard holds in the stablecoin issuance layer.
Stripe subsequently launched stablecoin-powered financial accounts accessible to businesses in 101 countries. The company processed $1.9 trillion in total payments in 2025, up 34% year-over-year. Stripe's latest valuation stood at $159 billion.
While Visa and Mastercard operate at the settlement layer between issuers and acquirers, Stripe/Bridge occupies the issuance and orchestration layer — minting, converting, and routing stablecoins for merchants and businesses directly. The competitive overlap occurs where settlement meets merchant payout: both sides want to be the last mile between on-chain dollars and a merchant's bank account.
The scale comparison between stablecoins and traditional card networks has shifted materially:
| Metric | Value | Source | |--------|-------|--------| | Adjusted stablecoin volume, 2025 | $10.9T | Chainalysis | | Visa total payment volume, 2025 | $14.2T | Visa 10-K | | Mastercard payment volume, 2025 | $10.6T | Mastercard 10-K | | Stablecoin-linked card spend, 2025 | ~$5.2B | Insights4VC | | Visa stablecoin settlement run rate | $7B annualized | Visa (April 2026) | | B2B stablecoin payments, 2025 | $226B | Industry estimates | | Stablecoin market cap (peak) | $323B | CoinDesk/DefiLlama | | USDT market cap | $190B | Tether (April 2026) | | USDC market cap | $77.6B | Circle (April 2026) | | Stablecoin CAGR (2023–2025) | 133% | Chainalysis |
Chainalysis projects adjusted stablecoin transaction volume could reach $719 trillion by 2035 through organic growth alone; with macro catalysts such as the generational wealth transfer ($100 trillion moving from Boomers to Millennials/Gen Z between 2028 and 2048), the figure could approach $1.5 quadrillion.
Cross-border B2B stablecoin payments are projected to reach $5 trillion by 2035, according to Juniper Research, representing more than 37,000% growth from 2025 levels.
The economic value in card settlement today flows through interchange fees (paid by acquirers to issuers), network fees (retained by Visa/Mastercard), and processing fees. For Mastercard, net revenue reached $32.8 billion in 2025, up 16% year-over-year.
Stablecoin settlement introduces new value-extraction points:
The card networks' strategic interest lies in retaining their network fee while adding stablecoin as a settlement option that reduces their own treasury management costs. Faster settlement (same-day vs. T+1 or T+2) improves capital efficiency for both issuers and acquirers, which the networks can monetize through premium settlement tiers.
The integration proceeds against an evolving U.S. regulatory environment. The GENIUS Act, designed to establish a federal framework for stablecoin issuance and oversight, has reached its deadline without final rules. Bridge's OCC trust charter represents one path to federal legitimacy; Circle has separately pursued registration.
In the EU, MiCA implementation continues, with compliance deadlines creating operational pressure for stablecoin issuers and the card programs that depend on them. Mastercard's selection of regulated stablecoins (USDC, PYUSD, RLUSD) for its settlement program reflects a compliance-first approach that limits exposure to regulatory uncertainty.
The practical effect: card networks serve as a compliance wrapper around stablecoin settlement. Transactions that settle in USDC on Solana pass through the same KYC/AML infrastructure as traditional card transactions. This dual-layer compliance — blockchain transparency plus card-network reporting — may prove the strongest argument for institutional adoption.
The three largest Western payment processors have moved from observing stablecoins to embedding them as a settlement option. The combined capital deployed — $2.9 billion in acquisitions alone — represents a structural bet that on-chain dollars become a standard settlement medium within existing card infrastructure.
The near-term constraint is volume. Visa's $7 billion stablecoin settlement run rate, while growing rapidly, represents approximately 0.05% of its total payment volume. Mastercard has not disclosed comparable figures. The gap between stablecoin's macro transaction volume ($10.9 trillion) and its penetration into card settlement ($5.2 billion in card spend) underscores that most stablecoin activity still occurs outside traditional payment networks — in DeFi, peer-to-peer transfers, and crypto trading.
The economic question for Visa and Mastercard is whether stablecoin settlement cannibalizes existing interchange revenue or expands the addressable market. If stablecoin settlement primarily serves crypto-native issuers who would not otherwise be on-network, it is additive. If it migrates existing fiat settlement to lower-margin on-chain rails, the networks face margin compression.
For now, the card networks are positioning stablecoins as a premium settlement option — faster, available 24/7, with enhanced liquidity management — rather than a replacement for fiat settlement. The BVNK and Bridge acquisitions suggest both Mastercard and Stripe expect the premium model to generate sufficient volume to justify multi-billion-dollar entry costs. Whether that volume materializes depends less on technology than on whether issuers, acquirers, and merchants find sufficient cost savings to shift settlement behavior at scale.
