OUSD vs. USDT and USDC: A Comparison of Institutional Adoption
2026-09-15
Two stablecoins have controlled the market for years. Now a third is being built to break that hold.
On June 30, 2026, a consortium called Open Standard unveiled Open USD (OUSD), a dollar-backed stablecoin supported by more than 140 companies including Visa, BlackRock, Stripe, Mastercard, Coinbase, and Google.
The announcement sent Circle's stock down over 13% in a single session. OUSD has not gone live yet, but the scale of institutional backing behind it has already reshaped the competitive landscape.
This guide breaks down how OUSD compares to USDT and USDC across governance, fees, revenue mechanics, and institutional adoption.
Key Takeaways
- USDT and USDC together control approximately $258 billion in market value and over 82% of the total stablecoin market as of September 2026. Both operate under single-issuer models where one company retains reserve income.
- Open USD (OUSD) introduces a consortium-governance model where over 140 partner companies share in reserve earnings and participate in governance, rather than ceding control and revenue to a single issuer.
- OUSD has not launched yet and is expected to go live later in 2026. Until it does, all claims about its mechanics, governance, and adoption remain based on the announcement, not observed on-chain performance.
What Is Open USD (OUSD)?
Open USD is a dollar-backed stablecoin created by Open Standard, an independent entity announced on June 30, 2026.
Unlike USDT and USDC, which are issued and controlled by single companies (Tether and Circle respectively), OUSD operates under a consortium model. More than 140 companies across payments, banking, technology, and crypto have joined as founding partners.
The partner list spans the full spectrum of global finance and technology:
- Payments and Fintech: Visa, Mastercard, Stripe, American Express, Adyen, Klarna, Affirm, Brex, Western Union
- Banking and Financial Services: BlackRock, BNY, Standard Chartered, DBS, U.S. Bank, BBVA, Commonwealth Bank of Australia
- Technology: Google, Shopify, IBM, DoorDash, Rakuten
- Crypto and Blockchain: Coinbase, Solana, Ripple, OKX, Bybit, Fireblocks, Aptos Labs, Aave
Zach Abrams, co-founder and CEO of Stripe-owned Bridge, serves as Open Standard's founding CEO. The stablecoin is designed to launch natively on Solana, with planned expansion to Polygon, Aptos, and Stellar.
Coinbase has confirmed OUSD will come to Base, and Stripe has announced OUSD will become the default stablecoin for businesses transacting on its platform.

USDT and USDC: The Incumbents
Before examining how OUSD differs, understanding the current stablecoin landscape is essential. USDT and USDC have dominated this market for years, and their combined position as of September 2026 remains formidable.
Tether's USDT remains the largest stablecoin by a wide margin, holding approximately $183.4 billion in market capitalisation and roughly 60% of total stablecoin supply.
Its dominance on centralised exchanges is even more pronounced, accounting for approximately 74% of on-chain trading volume on those platforms.
Circle's USDC holds the second position at $74.2 billion. Despite its smaller supply, USDC overtook USDT by annual adjusted transaction volume in 2025, processing $18.3 trillion compared to USDT's $13.3 trillion.
In Q1 2026, USDC accounted for roughly 80% of total organic on-chain stablecoin transaction volume across a $28 trillion quarter, surpassing USDT in organic settlement flows for the first time since 2019.
Together, USDT and USDC leave less than $53 billion for all other stablecoins combined. That concentration, roughly 82 to 88% of the total market depending on the source, is the barrier OUSD must overcome.
OUSD vs. USDT and USDC: Feature Comparison
The differences between OUSD and the incumbents go beyond backing and market share. They reflect fundamentally different approaches to how a stablecoin should be governed, who should benefit from its growth, and how adoption should be incentivised.
Three structural differences stand out.
The first is the revenue model. Under the incumbent approach, Tether and Circle sit on a combined stablecoin float of approximately $258 billion and capture the interest income generated by investing those reserves in government securities and other low-risk assets. Tether alone reported billions in quarterly profits from this model.
OUSD inverts this structure. Partners in the Open Standard network receive direct payouts proportional to the OUSD volume they push and hold, minus a small management fee retained by Open Standard.
This turns institutional partners from passive distribution channels into financially incentivised adoption engines.
The second is governance. USDT and USDC are governed by single corporate entities that make unilateral decisions about reserves, chain deployments, and compliance standards.
OUSD places governance with an independent board composed of partner representatives, distributing decision-making across the consortium.
The third is cost structure. Minting and redeeming USDT or USDC at institutional scale involves fees that add up for treasury and payments teams operating at high volume.
OUSD eliminates these fees entirely, removing a cost barrier that has historically slowed institutional stablecoin adoption.
Institutional Adoption and the Revenue Model Shift
The scale of institutional backing behind OUSD is unprecedented for a stablecoin launch. No previous stablecoin has launched with this breadth of corporate support across payments, banking, technology, and crypto simultaneously.
Stripe has committed to making OUSD the default stablecoin for businesses running on its platform.
This single integration could drive significant volume, given that Stripe processes hundreds of billions in annual payment volume for millions of businesses globally.
Coinbase has confirmed OUSD will be available on Base. Visa and Mastercard joining as partners signals that the card networks see OUSD as infrastructure worth backing rather than a threat to their existing rails.
The revenue-sharing model is what makes this coalition possible. Under the USDT and USDC model, partners like Visa, Stripe, and Coinbase act as distribution conduits without capturing any of the reserve yield their adoption helps generate. OUSD changes that equation.
By routing most reserve earnings back to partners, Open Standard creates a self-reinforcing incentive loop: the more OUSD circulates, the more reserve earnings flow back to the companies that build adoption.
This model has drawn comparisons to Meta's abandoned Libra (later Diem) project, which attempted a similar consortium approach in 2019 before regulatory pressure dismantled it.
The key difference is timing. The 2025 GENIUS Act established a federal regulatory framework for stablecoins in the United States, providing the legal clarity that Libra lacked.
OUSD launches into a regulated environment that actively encourages institutional participation rather than punishing it.

Risks and Open Questions for OUSD
Despite the heavyweight backing, OUSD faces significant challenges that traders and institutions should monitor.
OUSD has not launched yet. Every claim about its mechanics, governance, and partner economics is based on the June 30, 2026, announcement, not on observed on-chain behaviour.
Key details remain unconfirmed, including the exact reserve composition, the custodian holding reserves, the management fee percentage, the attestation publishing schedule, and the full list of supported chains at launch.
ARK Invest research director Lorenzo Valente has publicly questioned whether a consortium of roughly 500 competing entities can coordinate fast enough to compete with the speed and agility of single-issuer stablecoins.
Circle and Tether can ship upgrades, add chains, and adjust policies unilaterally. OUSD's governance model may introduce decision-making friction that slows its ability to respond to market conditions.
Network effects are also a challenge. USDC's DeFi integrations, built over years of chain-by-chain deployments and developer tooling, are not easily displaced by a consortium still finalising its compliance and governance structure.
USDT's dominance on centralised exchanges rests on liquidity depth that takes years to establish. OUSD will need to build both from scratch.
The most likely near-term scenario, according to institutional analysis, is that OUSD operates within each partner's closed ecosystem (Stripe merchants, BNY institutional clients, Coinbase exchange users) rather than competing for the open, composable DeFi volume that anchors USDC's dominance.
Whether it breaks out of those walled gardens will determine its long-term trajectory.

Conclusion
The stablecoin market is entering its most competitive phase yet. USDT and USDC have dominated for years through first-mover advantage, deep liquidity, and extensive chain integrations.
OUSD challenges that dominance not by competing on the same terms, but by restructuring the economic model entirely, turning institutional partners from passive distribution channels into revenue-sharing stakeholders.
Whether that model can overcome the network effects, DeFi integrations, and liquidity depth of the incumbents remains the open question heading into OUSD's expected launch later in 2026.
Until OUSD goes live and demonstrates real on-chain performance, USDT and USDC remain the functional standards for the stablecoin economy.
