Since 2026, the competitive dynamics in the stablecoin market have been shifting. Previously, discussions around USDC focused on its rivalry with USDT for market share and changes in circulation volume. However, this year, Circle has noticeably accelerated its initiatives. Whether it’s the Circle Payments Network, the Arc network, the planned Aave V4 deployment, or cross-border payment partnerships and institutional adoption, USDC’s role is evolving. It’s no longer just a dollar-denominated tool for exchanges; it’s now entering more complex financial scenarios such as payments, DeFi, corporate settlements, RWA, and on-chain capital markets.
For Circle, the future focus may no longer be on who issues the most stablecoins, but rather on who can become the infrastructure provider for the digital dollar era.
USDC’s Continued Growth: Changing Demand for On-Chain Dollars
According to Circle’s Q1 2026 financial report released in May, USDC’s circulating supply reached approximately $77 billion by the end of the first quarter, marking a 28% year-over-year increase. During the same period, USDC’s on-chain transaction volume hit $21.5 trillion, soaring by 263% compared to the previous year.
Meanwhile, the company’s total revenue and reserve income for the quarter reached $694 million, up about 20% year-over-year. Unlike a few years ago, when USDC primarily served crypto trading needs, the sources of its growth have clearly shifted.
Historically, stablecoins were mostly used for exchange settlements and DeFi liquidity. But with the rise of ETFs, RWA, stablecoin payments, and institutional capital flowing onto the blockchain, more businesses and financial institutions now view USDC as a programmable dollar asset.
A quarterly transaction volume of $21.5 trillion indicates that USDC’s use cases have expanded far beyond internal exchange transfers, moving into payments, fund management, on-chain lending, and asset tokenization.
The market’s demand for stablecoins is also shifting—from being primarily a trading tool to becoming a broader financial instrument.
Circle Payments Network: Redefining Cross-Border Payments
Payments have always been one of Circle’s most strategic priorities. In 2025, Circle launched the Circle Payments Network (CPN), aiming to build a global payment network powered by stablecoins. According to Circle, CPN is designed for banks, payment providers, and fintech companies, enabling near real-time settlements via USDC and offering a unified compliance framework.
From a business model perspective, Circle is tackling longstanding issues in traditional cross-border payment systems.
Conventional international remittances rely on the SWIFT network and multiple intermediaries, which can take days for funds to clear. There are also constraints such as time zones, holidays, and fees. Stablecoin networks, by contrast, operate 24/7 and significantly boost the efficiency of capital flows.
In May 2026, global payments infrastructure provider Nium announced a partnership with Circle to connect USDC settlement capabilities via Circle Payments Network to a payment network covering over 190 countries and regions and more than 100 currencies.
In June, Philippine fintech company Munify officially integrated with the Circle Payments Network, enabling users to receive funds in USDC and convert them directly to Philippine pesos for deposit into local bank accounts and e-wallets.
The Philippines is one of the world’s largest overseas remittance markets, with annual cross-border remittances totaling about $40 billion. For Circle, these real-world payment scenarios offer far greater long-term value than exchange-based liquidity.
In a sense, Circle is working to build a global payment network for the stablecoin era.
Behind Arc: Circle Is Building Its Own Financial Infrastructure
Beyond payments, Circle’s efforts to build its own infrastructure layer deserve even more attention.
In 2025, Circle launched Arc, positioning it as an infrastructure network for the stablecoin financial ecosystem. Unlike Layer 1 blockchains that focus on general-purpose smart contracts, Arc emphasizes payments, digital dollar liquidity, RWA, and institutional finance.
According to data released by Arc, the testnet has already attracted participation from institutions and protocols including BlackRock, Visa, AWS, Maple, and Curve. To date, it has processed over 150 million transactions, with about 1.5 million active wallets.
While these numbers are still early-stage, they already reflect Circle’s strategic direction.
In recent years, stablecoin issuers have mainly relied on reserve asset yields for revenue. Circle is now working to establish a new growth trajectory. If USDC represents the digital dollar, Arc is more like the underlying system powering its operation. From this perspective, Circle’s ambitions extend beyond issuing stablecoins—they’re building the entire internet financial system.
Aave V4 Deploys on Arc: USDC Enters Capital Market Infrastructure
At the end of May 2026, Aave Labs proposed deploying its next-generation lending protocol, Aave V4, onto the Arc network.
This news drew significant attention, as it signals a potential shift in USDC’s positioning.
Previously, USDC was primarily used for payments and settlements. With Aave V4’s integration, USDC is entering deeper layers of capital formation.
Lending markets are a core component of financial systems. Banks create credit through deposits and loans, capital markets allocate liquidity via lending, and DeFi essentially extends these mechanisms onto the blockchain.
The combination of Aave V4 and Arc means Circle is moving from payment infrastructure into capital market infrastructure.
If payment networks solve the problem of capital flow, lending markets address capital allocation.
That’s why the market is starting to compare Circle to traditional payment companies. Circle’s ambition is no longer just to be a stablecoin issuer—it’s aiming to become a key infrastructure provider in the digital finance era.
Circle Is Telling the Story of the "Internet Financial System"
At the beginning of 2026, Circle published a report titled "The Rise of the Internet Financial System."
In this report, Circle introduced a new concept: the Internet Financial System.
Circle envisions a future financial ecosystem composed of stablecoins, payment networks, RWA, on-chain capital markets, and AI agent economies, with USDC as the core asset.
Previously:
- USDC = Stablecoin
Now:
- USDC = Payment Network
- USDC = On-chain Cash
- USDC = DeFi Liquidity
- USDC = RWA Settlement Tool
- USDC = Corporate Fund Management Tool
- USDC = Value Medium for AI Economies
This transformation reflects an upgrade in the competitive logic of the entire stablecoin industry.
Market competition is shifting from issuance volume to ecosystem capabilities.
Stablecoin Competition Enters a New Phase
In recent years, competition between USDT and USDC has mainly centered on market share and circulation volume.
But as stablecoin payments, RWA, and institutional adoption continue to grow, the dimensions of industry competition are changing.
In the future, the long-term value of stablecoins may depend less on circulation volume and more on who can build a comprehensive ecosystem spanning payments, capital markets, asset tokenization, and global settlement.
From this perspective, Circle’s development path increasingly resembles that of a payment network or financial infrastructure company.
Many research institutions are even beginning to describe Circle as the Visa of the stablecoin era or a blockchain-based SWIFT.
Of course, this vision will take time to materialize.
But one thing is clear: the stablecoin market has entered a new phase.
Conclusion
Since 2026, Circle’s strategic focus has undergone a significant shift.
According to Circle’s latest data, USDC’s Q1 on-chain transaction volume reached $21.5 trillion, with a circulating supply of $77 billion. Meanwhile, the Circle Payments Network continues to expand global payment capabilities, while Arc and Aave V4 are further driving USDC’s extension into DeFi and capital markets.
From stablecoin payments to on-chain financial infrastructure, from cross-border settlement to RWA and institutional finance, Circle is working to build an internet financial system centered around the digital dollar.
For USDC, its greatest potential may no longer lie in the stablecoin itself, but in its role within the broader digital financial ecosystem.
