Visa, Mastercard, Stripe, PayPal, and Western Union have collectively deployed more than $4 billion in acquisitions and committed infrastructure capital to stablecoin payment rails since early 2025. In the span of 18 months, the five largest legacy payment networks have shifted from observing stablecoin markets to building native stablecoin products, acquiring stablecoin companies, and settling live transaction volume on public blockchains.
Adjusted stablecoin transaction volume reached a record $1.79 trillion in June 2026, according to Visa's Allium-powered onchain analytics dashboard — a 125% increase from June 2025. The first half of 2026 totaled $8.82 trillion in adjusted volume. USDC accounted for approximately 67% of that throughput. The organic, adjusted stablecoin volume now rivals Mastercard's full annual card processing throughput of approximately $8.5 trillion.
This report examines the specific positions, deal structures, and economic logic driving each legacy payment network's stablecoin strategy — and what the convergence means for the $310 billion stablecoin market.
The stablecoin market's aggregate supply stood at approximately $310 billion as of mid-August 2026, according to data from CoinGecko and StablecoinBeat. Tether's USDT held $183.4 billion in market cap. Circle's USDC held $75.6 billion. Together they command 82.3% of supply.
But supply is only half the story. Adjusted transaction volume — stripped of bot trades, MEV activity, and internal exchange shuffles — hit $1.79 trillion in June 2026, per Visa's onchain analytics dashboard. That figure rose 63% from May's $1.1 trillion and 125% year-over-year. The first-half 2026 total: $8.82 trillion.
For context: Visa processes approximately $17 trillion annually across its card network. Mastercard handles roughly $8.5 trillion. The adjusted stablecoin run rate of approximately $21.5 trillion annualized (extrapolating from June) now exceeds Mastercard's full-year volume and approaches Visa's.
The five legacy payment networks profiled in this report have each responded with distinct but converging strategies.
On March 17, 2026, Mastercard announced a definitive agreement to acquire BVNK, a stablecoin payment infrastructure company, for up to $1.8 billion including $300 million in contingent payments. The deal closed on August 3, 2026 — Mastercard's largest acquisition in the digital asset space.
BVNK operates in more than 130 countries with 25 or more regulatory licenses and processes approximately $30 billion in annualized stablecoin volume as of mid-2026. The platform provides on-ramp, off-ramp, settlement, and treasury management infrastructure connecting fiat rails to on-chain stablecoin flows.
The acquisition's timing coincides with Mastercard's June 2026 announcement expanding its Multi-Token Network to support stablecoin settlement directly. Mastercard CEO Michael Miebach framed the company as "the operating system of the digital economy" with "a money movement layer — across stablecoins and account-to-account and cards."
The deal valued BVNK at roughly 60x its reported revenue, according to Fortune — a multiple that reflects the strategic premium Mastercard placed on owning stablecoin plumbing rather than building it internally.
Visa's stablecoin settlement pilot, initially launched on Ethereum and Solana, expanded to nine blockchains by April 2026. The company added Base, Polygon, Canton Network, Arc, and Tempo to its existing Ethereum, Solana, Avalanche, and Stellar support.
The pilot reached a $7 billion annualized settlement run rate as of April 29, 2026, up 50% from the prior quarter. Visa supports more than 130 stablecoin-linked card programs across 50 countries. The settlement service allows issuers and acquirers to settle in USDC rather than routing through correspondent banking.
A key infrastructure partnership: Visa extended its relationship with Stripe-owned Bridge to launch stablecoin-backed card programs in more than 100 countries by end of 2026. Early issuers in that program include Ramp, Squads, and Airtm.
Visa also operates the Allium-powered onchain analytics dashboard that has become a standard industry reference for adjusted stablecoin volume data — effectively positioning itself as both a participant in and the primary data provider for stablecoin settlement metrics.
Stripe closed its $1.1 billion acquisition of Bridge Network in February 2025, at the time the largest acquisition in Stripe's history. Bridge provides stablecoin issuance, custody, and orchestration infrastructure.
In February 2026, Bridge received a conditional national trust bank charter from the Office of the Comptroller of the Currency (OCC), giving it federal oversight for stablecoin issuance, digital asset custody, and reserve management. This charter positions Stripe-Bridge as a federally regulated stablecoin issuer — a status distinct from Tether (offshore) and Circle (state-licensed money transmitter).
In September 2025, Stripe and Paradigm launched Tempo, a blockchain designed specifically for stablecoin payments. Tempo is now one of nine chains supported by Visa's stablecoin settlement pilot.
Stripe CEO Patrick Collison described stablecoins as "room-temperature superconductors for financial services." The company's stablecoin strategy centers on the orchestration layer — the infrastructure that converts, routes, custodies, screens, and reconciles transactions between fiat and token — rather than on earning issuance yield from reserves.
PayPal's dollar stablecoin, PYUSD, reached approximately $4.3 billion in circulating supply by Q2 2026 — more than quintupling over the prior year. The token is deployed across 17 blockchain networks, with Ethereum holding 73% of supply and Solana serving as the default network for payment processing since February 2026.
PYUSD holder count surged by more than 1,500% over the past two years, reaching over 118,900 addresses. On March 17, 2026, PayPal expanded PYUSD availability to 70 markets globally.
PayPal's stablecoin model differs from the other four networks: PayPal is a direct issuer. PYUSD is embedded in the PayPal and Venmo consumer apps alongside fiat balances. The "Pay with Crypto" service charges 0.99% per transaction — approximately 90% less than standard international credit card interchange rates.
PYUSD is currently the seventh-largest stablecoin by market capitalization. It remains small relative to USDT and USDC but sits within one of the largest consumer payment ecosystems globally, with PayPal's 400 million-plus active accounts providing a distribution channel that no crypto-native issuer can match.
Western Union launched USDPT, a dollar-denominated stablecoin issued by Anchorage Digital Bank on the Solana blockchain, on May 4, 2026. Fireblocks provides wallet, settlement, and financial operations infrastructure. The initial rollout targeted the Philippines and Bolivia — two of the world's largest remittance-receiving corridors.
On August 4, 2026, Western Union and Rain debuted the Stablecard, a USDPT-backed Visa card, across 37 markets with a target of 60 markets by year-end. The card allows users to spend stablecoin balances at any of Visa's 175 million merchant locations. A "Cash Redirect" feature lets recipients of Western Union remittances route incoming transfers directly into a Stablecard wallet.
The consumer product "Stable by Western Union" is planned for launch in more than 40 countries in 2026.
The fee economics are stark. According to data compiled by Spark Research, a $500 monthly remittance from California to the Philippines through Western Union's traditional service costs approximately $35 per transfer and takes three days to settle. A stablecoin-based transfer through a digital corridor costs less than $3 and settles in under 10 minutes. Once Western Union's own FX spread is included, the total cost of a traditional $500 transfer rises to 4-6% — compared to under 1% for native stablecoin transfers.
Western Union's strategic logic: cannibalize its own fee structure before fintech competitors and crypto-native remittance platforms do it for them.
A pattern emerges across all five players. Almost none of the corporate capital deployed targets issuance economics — the interest earned on reserves backing stablecoins. Instead, the capital flows into orchestration: the infrastructure that converts, routes, custodies, screens, and reconciles value between fiat and token.
Mastercard paid $1.8 billion for BVNK's orchestration layer. Stripe paid $1.1 billion for Bridge's orchestration layer. Visa built its own. PayPal is both issuer and orchestrator through its consumer apps. Western Union paired Anchorage as issuer with Fireblocks and Rain as orchestration partners.
The economic rationale: stablecoin issuance generates reserve yield (currently 4-5% on U.S. Treasuries), but the issuer must maintain full reserves and absorb compliance costs. Orchestration generates transaction fees on every conversion, routing, and settlement event — without the balance-sheet requirements.
This aligns with how the traditional card networks have historically operated. Visa and Mastercard do not lend money; they tax the movement of money. Their stablecoin strategies replicate this model on-chain.
The GENIUS Act, signed into law on July 18, 2025, formalized the regulatory framework enabling this convergence. The law restricts stablecoin issuance to regulated institutions — banks, credit unions, and specially licensed non-bank issuers — while creating clear definitions for "payment stablecoins." Seven major economies (US, EU, UK, Singapore, Hong Kong, UAE, Japan) now mandate full reserve backing, licensed issuers, and guaranteed redemption rights.
The migration of legacy payment networks onto stablecoin rails represents a structural shift in how value moves globally. It is not speculative positioning — Visa is settling $7 billion annually on nine blockchains, Mastercard now processes $30 billion in annualized stablecoin volume through BVNK, and Western Union is deploying stablecoin cards in 37 markets.
The competitive question is no longer whether traditional payment companies will use stablecoins, but how quickly the economics of orchestration — conversion fees, settlement charges, compliance screening — will compress toward zero as five major networks compete for the same flows.
The $310 billion stablecoin market is no longer a crypto sideshow. It is the settlement layer that legacy payment infrastructure is rebuilding itself around.
