"We're not asking whether stablecoins will be part of the payments system. They already are." — Cuy Sheffield, Head of Crypto, Visa
Visa, Mastercard, and Stripe have collectively deployed more than $4.7 billion in acquisitions and infrastructure to integrate stablecoins into traditional payment rails. Visa's stablecoin settlement pilot reached a $7 billion annualized run rate across nine blockchains as of April 2026, up 50% quarter-over-quarter. Mastercard closed its $1.8 billion acquisition of London-based BVNK in March 2026, the largest stablecoin infrastructure deal on record. Stripe's Bridge subsidiary, acquired for $1.1 billion in early 2025, saw transaction volume quadruple last year and is now powering stablecoin-linked Visa cards in 18 countries with plans to reach 100+ by year-end.
The race is structural, not speculative. Stablecoin payment volume reached $33 trillion in 2025, up 72% year-over-year, according to industry data. The total stablecoin supply hit $323 billion in May 2026. For card networks that collectively processed over $10 trillion in US card spending in 2025, the math is simple: absorb stablecoins into existing rails or risk disintermediation by sub-cent settlement costs that bypass the 2-3% interchange fee model entirely.
This report examines the capital deployed, infrastructure built, and economic incentives driving the card networks' stablecoin absorption strategy — and the structural tension between preserving interchange revenue and embracing frictionless settlement.
Three transactions define the infrastructure buildout:
| Acquirer | Target | Price | Date | Function | |----------|--------|-------|------|----------| | Stripe | Bridge | $1.1B | Feb 2025 | Stablecoin issuance and orchestration | | Mastercard | BVNK | $1.8B (incl. $300M earnout) | Mar 2026 | On-chain/fiat payment bridging | | Visa | Internal build + partnerships | Est. $1.8B+ cumulative | 2023-2026 | Multi-chain settlement layer |
The combined $4.7 billion represents the largest concentrated capital deployment into stablecoin infrastructure by incumbent payment processors. For context, total venture capital into crypto startups ran approximately $13-20 billion annually in 2024-2025, according to webthreepedia's foundational economic value analysis.
Mastercard's BVNK acquisition is notable for its premium. BVNK raised its Series B at a $750 million valuation in December 2024. Fifteen months later, Mastercard paid 2.4x that figure. Coinbase had reportedly approached BVNK at approximately $2 billion before negotiations collapsed in November 2025, according to CNBC.
Visa's stablecoin settlement program now spans nine blockchains after adding five networks in April 2026:
Original four: Ethereum, Solana, Avalanche, Stellar
Added April 2026: Base (Coinbase), Polygon, Canton Network, Arc (Circle), Tempo (Stripe)
The $7 billion annualized run rate represents live transaction volume, not projections, according to Visa's investor relations filings. The company emphasized this is actual settlement flowing through blockchain rails rather than traditional correspondent banking.
The chain selection reveals strategic alignment. Arc is Circle's purpose-built Layer 1 for programmable money. Tempo is Stripe's settlement-focused chain. Canton offers configurable privacy for regulated capital markets. Base is Coinbase's Ethereum L2. Each chain serves a distinct institutional use case rather than competing on the same axis.
Visa supports more than 130 stablecoin-linked card programs across 50+ countries. USDC settlement has been extended to nine US banks. The settlement program lets issuers and acquirers clear transactions in stablecoins instead of through traditional correspondent banking, reducing settlement times from T+2 to near-real-time.
By selecting chains associated with Circle, Stripe, and Coinbase — three of the largest US-regulated crypto companies — Visa is building a settlement layer that maps to the emerging US regulatory framework under the GENIUS Act and CLARITY Act now progressing through Congress.
Mastercard's approach differs from Visa's. Rather than building multi-chain settlement internally, Mastercard acquired an existing stablecoin orchestration platform.
BVNK, founded in 2021, enables businesses to send and receive stablecoin payments across 130+ countries on all major blockchain networks. The platform functions as a bridge between on-chain stablecoin flows and traditional fiat payment rails — precisely the infrastructure Mastercard needed to connect its Multi-Token Network (MTN) to live transaction volume.
Mastercard's MTN is a regulated blockchain environment designed for banks to transact tokenized deposits and stablecoins. Combined with Crypto Credential, Mastercard's compliance and identity layer, the BVNK acquisition creates a vertically integrated stack: identity verification, on-chain transaction routing, and fiat settlement in a single pipeline.
The deal structure — $1.5 billion upfront plus $300 million in performance-contingent payments — suggests Mastercard is benchmarking BVNK against specific volume and integration milestones. The earnout structure implies the acquisition value is tied to BVNK's ability to convert Mastercard's existing merchant network to stablecoin-capable settlement.
Stripe occupies a distinct position. As a payment processor rather than a card network, Stripe competes with Visa and Mastercard on infrastructure control while simultaneously partnering with them on card issuance.
Bridge, acquired for $1.1 billion, saw stablecoin transaction volume quadruple in 2025. Stripe processed $1.9 trillion in total payment volume during 2025, giving Bridge access to an enormous existing merchant base.
In March 2026, Visa and Bridge announced a collaboration to bring stablecoin-linked cards to 100+ countries by year-end. Bridge-enabled cards are live in 18 countries. Platforms including Phantom and MetaMask use Bridge-powered cards to let users spend stablecoins at Visa's 175 million+ merchant locations.
Bridge also launched Open Issuance, a platform enabling businesses to create their own stablecoins — positioning Stripe not merely as a payment processor but as stablecoin infrastructure-as-a-service. This vertical integration, from issuance through settlement, gives Stripe potential leverage that neither Visa nor Mastercard currently possesses.
The competitive tension is visible. Stripe simultaneously collaborates with Visa on card issuance and competes with it on settlement infrastructure. Bridge's Open Issuance platform could, in theory, enable stablecoin flows that bypass card network rails entirely.
PayPal represents a fourth model: issuing a proprietary stablecoin and embedding it inside an existing consumer and merchant network.
PYUSD reached a $4.1 billion market cap as of Q1 2026, growing 680% year-over-year — the fastest growth rate among major stablecoins, according to CoinGecko data. On March 17, 2026, PayPal extended PYUSD access from two markets (US and UK) to 70 markets in a single release, adding 68 countries across Asia-Pacific, Europe, Latin America, and North America.
The PYUSD model creates a closed-loop stablecoin payment system. Consumers hold PYUSD in PayPal wallets. Merchants receive PYUSD and can access proceeds within minutes. PayPal earns yield on the reserves backing PYUSD while also collecting merchant processing fees — a dual revenue model unavailable to networks that merely settle third-party stablecoins.
PayPal has also partnered with Mastercard on future PYUSD settlement capabilities, creating an additional distribution channel through Mastercard's merchant network.
The central tension in this buildout is economic. Visa and Mastercard's combined 2025 US card purchase volume exceeded $10 trillion, generating revenue through interchange fees typically ranging from 1.5-3% of transaction value. Their combined global revenue is projected to approach $163 billion in 2026.
Stablecoin settlement costs a fraction of a cent per transaction. AI agents optimized for cost efficiency can detect the 2-3% interchange spread and route payments through stablecoin rails instead. The card networks' own stablecoin infrastructure thus creates a pathway for their most sophisticated users to bypass the interchange model.
This is the interchange paradox: the networks must build stablecoin settlement capability to remain relevant, but doing so commoditizes the settlement layer that generates their highest-margin revenue.
The current resolution appears to be a dual-rail strategy. Stablecoin settlement is positioned as a feature within existing card programs — stablecoin-linked cards still route through Visa/Mastercard networks, preserving interchange revenue even as the underlying settlement shifts to blockchain rails. The card networks maintain their position as merchant acceptance networks and compliance layers while adopting stablecoins as a settlement mechanism rather than a replacement for the card transaction itself.
Whether this equilibrium holds depends on whether merchants begin accepting stablecoin payments directly, bypassing card networks entirely. The infrastructure being built by Stripe, Circle, and independent stablecoin payment processors creates that option.
The infrastructure race is occurring against a backdrop of rapid stablecoin supply growth:
| Metric | Value | Date | |--------|-------|------| | Total stablecoin market cap | $323.2B | May 11, 2026 | | USDT (Tether) market cap | $189.7B | May 2026 | | USDC (Circle) market cap | $77.9B | May 2026 | | PYUSD (PayPal) market cap | $4.1B | Q1 2026 | | Stablecoin payment volume (2025) | $33T | Full year | | Cross-border B2B stablecoin payments | $13.4B est. | 2026 | | Projected B2B stablecoin payments | $5T | 2035 |
USDT and USDC together control approximately 83% of total stablecoin supply. The concentration creates a structural dependency for any payment network building on stablecoin rails — Visa's settlement architecture is heavily aligned with USDC, while Mastercard's BVNK supports multiple stablecoins including USDC, USDT, and PYUSD.
According to Juniper Research, cross-border B2B stablecoin payments are projected to reach $5 trillion by 2035, up from an estimated $13.4 billion in 2026. If accurate, this represents a 37,000% increase over nine years — driven primarily by the settlement cost advantage over traditional correspondent banking, which typically charges $25-50 per wire transfer versus sub-cent stablecoin transaction fees.
The B2B use case is where the economic value argument is strongest. Stablecoin settlement eliminates the multi-day float period in correspondent banking, reduces FX conversion layers, and provides programmable compliance through smart contracts. According to industry data, B2B transactions accounted for approximately 60% of all stablecoin payment volume in 2025.
$4.7 billion deployed. Visa, Mastercard, and Stripe have collectively spent $4.7B+ on stablecoin infrastructure through acquisitions and internal builds since 2023.
$7 billion in live volume. Visa's stablecoin settlement hit a $7B annualized run rate across nine chains, up 50% quarter-over-quarter. This is actual settlement, not projection.
130+ card programs in 50+ countries. Stablecoin-linked cards are already a multi-country, multi-network product — not a pilot.
The interchange paradox is unresolved. Card networks are building infrastructure that, at scale, could commoditize their highest-margin revenue stream. The current dual-rail strategy preserves interchange but may not survive direct merchant stablecoin acceptance.
Stripe holds unique leverage. Through Bridge's Open Issuance platform and its partnership with Visa, Stripe can both issue stablecoins and route them through card rails — vertical integration that neither Visa nor Mastercard alone possesses.
PYUSD's dual revenue model. PayPal earns both reserve yield and merchant processing fees on PYUSD — a model that pure network operators cannot replicate.
Regulatory alignment shapes chain selection. Visa's nine-chain architecture favors US-regulated entities (Circle, Coinbase, Stripe), positioning for compliance under GENIUS Act and CLARITY Act frameworks.
The card networks' stablecoin buildout represents the largest infrastructure convergence between traditional finance and blockchain since SWIFT began its shared-ledger pilot. The $4.7 billion in deployed capital is not speculative — it is purchasing live transaction volume, merchant connectivity, and regulatory positioning.
The economic question is whether stablecoin settlement will expand the total addressable market for card networks (by enabling cheaper cross-border settlement that brings new transaction types onto their rails) or cannibalize existing interchange revenue (as merchants and AI agents route around card fees).
Both outcomes are likely to occur simultaneously. The networks that control the most merchant acceptance points, compliance infrastructure, and multi-chain settlement capability will capture the largest share of stablecoin payment flows. The card networks are betting that their existing 175 million+ merchant network and decades of compliance infrastructure constitute a moat that stablecoin-native payment processors cannot easily replicate.
Whether that moat holds against sub-cent settlement costs and programmable money remains the open question of the next 24 months.
