"Stablecoins are room-temperature superconductors for financial services." — Patrick Collison, CEO, Stripe
Visa, Mastercard, Stripe, BlackRock, and Coinbase are among 140-plus companies backing Open USD, a partner-governed stablecoin announced June 30, 2026, that distributes reserve yield to participating businesses rather than retaining it at the issuer level. The initiative, organized under an entity called Open Standard, represents a coordinated attempt by incumbent payment networks to seize economics currently captured by Circle Internet Group and Tether Holdings.
The consortium's formation follows $2.9 billion in stablecoin infrastructure acquisitions by the three largest payment processors since late 2024 — Stripe's $1.1 billion purchase of Bridge, Mastercard's $1.8 billion acquisition of BVNK — and comes as Visa reports $70 billion in annualized stablecoin settlement volume. Circle's stock fell 17.5% the day Open USD was announced, and Mizuho subsequently downgraded the company to underperform with a $50 price target, down from $85.
The stablecoin market now stands at $308 billion in total capitalization as of August 2026. With stablecoin payment volume reaching an estimated $400 billion annually and B2B flows accounting for roughly 60% of that total, the question is no longer whether card networks will adopt stablecoin settlement — it is whether they will own the stablecoin itself.
Three transactions over 18 months reshaped payment-network exposure to stablecoin infrastructure:
Stripe–Bridge ($1.1B, closed February 2025). Stripe acquired Bridge, a stablecoin orchestration platform, for $1.1 billion — the company's largest acquisition to date. Bridge's infrastructure enables stablecoin payments across 70-plus countries, settling to USDC on Solana, Ethereum, or Polygon. According to Stripe's 2025 annual letter, published February 24, 2026, Bridge's transaction volume more than quadrupled year-over-year, while broader stablecoin payment volume processed through Stripe doubled to approximately $400 billion, with an estimated 60% in B2B flows, citing data from McKinsey and Artemis.
Mastercard–BVNK ($1.8B, announced March 2026). Mastercard agreed to acquire London-based stablecoin infrastructure firm BVNK for up to $1.8 billion, including $300 million in contingent payments, according to CNBC. BVNK operates across 130-plus countries and connects on-chain stablecoin payments with Mastercard's fiat settlement rails. According to CoinDesk, BVNK chose Mastercard over a reportedly higher offer from Coinbase due to strategic alignment.
Stripe–Privy (2025). Stripe also acquired Privy, a wallet infrastructure provider, to embed on-chain identity and key management directly into its payment stack.
Combined, these deals total $2.9 billion-plus deployed into stablecoin plumbing by firms that collectively process over $20 trillion in annual card volume.
On June 30, 2026, Open Standard — an independent company structured to operate on behalf of its partner network — announced Open USD (OUSD), a dollar-pegged stablecoin with a governance model distinct from existing issuers.
Partner roster. The consortium includes over 140 companies across payment networks (Visa, Mastercard), payments infrastructure (Stripe, Shopify), asset managers and banks (BlackRock, BNY, Standard Chartered), technology platforms (Google, IBM), and crypto-native firms (Coinbase, Solana Foundation, Aave).
Revenue-sharing model. Open USD's defining feature is its economic structure: nearly all interest earned on Treasury reserves backing the stablecoin flows to participating partners after a management fee, rather than accruing to a single issuer. This contrasts directly with Circle's model, where approximately 96% of the company's revenue derives from interest earned on USDC reserves, according to Circle's public filings.
Zero-cost mint and redeem. Open USD will offer fee-free minting and redemption at any scale, removing a friction point present in some existing stablecoin arrangements.
Governance. Partner companies occupy governance board seats, preventing any single entity from exercising unilateral control over the network. The model draws on open-standards governance principles rather than the single-issuer structure used by both Circle and Tether.
Expected launch. Open USD is targeted for the second half of 2026. As of this writing, the stablecoin has not yet gone live.
Visa's stablecoin infrastructure has scaled at a pace that warrants separate examination.
Settlement volume trajectory. Visa's stablecoin settlement program reached $4.5 billion in annualized volume by January 2026, according to company disclosures. By the time of Visa's Payments Forum in June 2026, that figure had grown to $70 billion annualized — a roughly 15x increase in under six months. The company has 160-plus stablecoin-linked card implementations across its network.
Stablecoin platform launch. In 2026, Visa introduced the Visa Stablecoin Platform, enabling banks and fintechs to mint, move, and manage stablecoins. According to investor relations materials, the platform provides end-to-end coverage from issuing to acquiring banks with real-time settlement.
Strategic framing. Jack Forestell, Visa's Chief Product and Strategy Officer, stated at the June 2026 Payments Forum: "AI is changing the front end of business, while stablecoins are reshaping the back end." CEO Ryan McInerney said Visa expects financial returns from stablecoin services comparable to those generated by its current card network operations, according to Payments Dive.
Geographic expansion. Visa extended its partnership with Stripe-owned Bridge to launch stablecoin-backed card programs in more than 100 countries by end of 2026, up from 18 countries in earlier pilots.
The economic case for stablecoin settlement rests on measurable cost differentials in cross-border payments.
SWIFT vs. stablecoin. Traditional cross-border wire transfers cost 2% to 7% all-in once fees, foreign exchange spreads, and intermediary charges are included, and typically settle in 1–5 business days. Stablecoin-based payments settle in under three minutes at costs between 0.1% and 0.5%, according to multiple industry reports and Stripe's published pricing (a flat 1.5% merchant fee for stablecoin acceptance, with lower rates on direct settlement).
Emerging-market corridors. The savings are most pronounced in high-friction corridors. India, Nigeria, Brazil, Argentina, Philippines, Turkey, and Pakistan — corridors where SWIFT costs routinely exceed 3% and settlement takes 24-plus hours — see 50–70% cost reductions via stablecoin settlement, according to data compiled by Tazapay and AlphaPoint.
Developed-market corridors. Between major economies with efficient banking infrastructure, the savings are smaller: $20–$80 per $50,000 transfer for USD-to-EUR routes where SWIFT GPI already delivers near-same-day settlement.
B2B scale. B2B stablecoin payments grew from under $100 million monthly in early 2023 to over $6 billion per month by mid-2025, a 60x increase in 30 months. At current growth rates, B2B stablecoin volume represents the fastest-growing segment of the $308 billion stablecoin market.
The Open USD announcement triggered immediate repricing of competitive risk for Circle Internet Group, which went public in 2025.
Stock impact. Circle shares (CRCL) fell 17.55% on June 30, 2026, the day Open Standard's consortium was revealed, reaching a four-month low, according to CoinDesk. Mizuho downgraded Circle to underperform from neutral and cut its price target from $85 to $50.
Business model vulnerability. According to CoinShares, Open USD represents "the most credible threat yet" to Circle's economics because it targets the revenue structure directly. Circle's Q2 2026 results showed total revenue and reserve income of $701 million, up 7% year-over-year. Roughly 96% of that comes from interest on Treasuries backing USDC — precisely the revenue stream Open USD's yield-sharing model is designed to redistribute.
Coinbase relationship. Coinbase, a founding partner of USDC alongside Circle, is also a backer of Open USD. At the end of Q2 2026, approximately 30% of USDC in circulation was held on Coinbase. Coinbase recorded $320 million in stablecoin revenue during the quarter — equivalent to 48% of Circle's quarterly reserve revenue, according to public filings.
Market positioning. USDC holds approximately $72.7–$73.7 billion in circulation as of mid-August 2026, representing about 24% of the $308 billion stablecoin market. Tether (USDT) dominates with $183.4 billion and 59% market share. Open USD, if it achieves meaningful adoption through its 140-partner distribution network, would compete most directly with USDC rather than USDT, given the consortium's institutional and compliance-oriented positioning.
Circle's recovery. Despite the initial shock, Circle's stock recovered to approximately $90–$94 by late August 2026 — a 41% rebound from early August lows near $58 — suggesting markets may view the competitive threat as longer-term rather than imminent.
Each major player has secured or is pursuing distinct regulatory footholds.
Bridge (Stripe). Bridge received conditional approval from the OCC for a national trust bank charter on February 12, 2026, according to OCC Corporate Decision #1365. The charter authorizes stablecoin issuance, digital asset custody, and reserve management under direct federal oversight. The Independent Community Bankers of America has raised concerns that stablecoin issuance under a trust charter — without FDIC insurance — risks regulatory arbitrage relative to traditional deposit-taking banks.
BVNK (Mastercard). BVNK holds licenses across 130-plus jurisdictions and will operate under Mastercard's existing compliance infrastructure post-acquisition.
GENIUS Act. The federal legislative framework for stablecoins remains incomplete. Congress delayed a floor vote on the GENIUS Act ahead of the August 2026 recess due to partisan disputes, scheduling a procedural vote for September 15, 2026. Meanwhile, the SEC's proposed "Regulation Crypto Assets" framework, announced August 18, 2026, addresses token offering registration but does not directly govern stablecoin issuance.
Paradigm Tempo. Paradigm announced Tempo, a payments-focused Layer 1 blockchain, in September 2025 with Stripe as a founding partner. The chain is designed as a stablecoin-settlement layer with fixed fees and compliance hooks for regulated entities.
The payment industry's stablecoin infrastructure build-out has moved past the pilot stage. Visa, Mastercard, and Stripe are no longer experimenting with blockchain settlement — they are acquiring companies, securing federal charters, and forming consortia to issue their own stablecoins. The $70 billion in annualized stablecoin settlement flowing through Visa alone exceeds the GDP of most mid-sized countries.
The formation of Open USD marks a structural shift in the stablecoin market's competitive dynamics. For the first time, the firms that control global payment distribution are also positioning to control the stablecoin itself. Circle, which built USDC's $73 billion circulation on the premise that it would remain the neutral infrastructure layer, now faces the prospect of its largest distribution partners launching a directly competing product — one that gives away the reserve yield Circle retains.
The stablecoin market's $308 billion capitalization is no longer a crypto-native phenomenon. It is a payments-industry battleground where the incumbents have arrived with acquisition budgets, regulatory licenses, and 140-company coalitions. The question of who captures stablecoin economics — issuers, platforms, or end users — will be answered in the next 12 to 18 months.
