Circle Internet Group makes money by issuing and operating regulated stablecoin infrastructure, mainly around USDC and EURC. Its core product is a fully backed digital dollar that customers use for payments, settlement, trading, treasury, remittances and onchain financial applications. The company also sells software, infrastructure and services that help enterprises, developers and financial institutions build with stablecoins.
The business is highly linked to stablecoin balances and interest rates. Circle’s largest revenue source is reserve income, which comes from interest and dividends earned on cash and investments backing USDC and EURC, including assets held through the Circle Reserve Fund managed by BlackRock. In Q2 2026, total revenue and reserve income was $701 million, up 7% year over year. Reserve income contributed $668 million, up 5%, while other revenue was $34 million, up 41%.
Circle tracks revenue less distribution costs as a key operating metric because distribution partners receive a significant share of the economics. In Q2 2026, revenue less distribution costs was $289 million, with a 41% margin. Adjusted EBITDA was $143 million, with a 50% adjusted EBITDA margin, while net income from continuing operations was $48 million.
The main revenue streams are
- Reserve income: Interest and dividends on segregated reserve assets backing USDC and EURC. This is the dominant revenue stream and is sensitive to both stablecoin circulation and market interest rates.
- Subscription and services revenue: Fees from platform access, integration work, maintenance, user-based licensing and related enterprise services.
- Transaction and infrastructure revenue: Fees from redemptions, transfers, settlement activity, APIs and digital-asset infrastructure.
- Tokenized asset revenue: Fund-management-related and infrastructure revenue linked to USYC, added through the Hashnote acquisition.
Circle’s operating platform includes USDC, EURC, USYC, Circle Mint, Circle Payments Network, Cross-Chain Transfer Protocol, Arc blockchain infrastructure and developer tools for programmable and agentic payments. These products give Circle exposure to stablecoin issuance, institutional settlement, tokenization, cross-border payments and developer-led financial applications.
The company’s main operating categories are
- Stablecoin issuance: USDC and EURC are fully backed stablecoins used for digital-dollar and digital-euro transactions.
- Institutional access: Circle Mint gives qualified customers minting, redemption and account infrastructure for stablecoin use.
- Payments infrastructure: Circle Payments Network supports stablecoin-based settlement between financial institutions and payment participants.
- Blockchain and developer infrastructure: Cross-Chain Transfer Protocol, Arc and agent-payment tools support programmable financial applications.
- Tokenized assets: USYC broadens the company into tokenized money-market-fund capabilities and onchain yield-bearing assets.
Circle’s main competitive advantage is its regulated, institution-focused positioning. It emphasizes reserve segregation, compliance, financial-institution partnerships and public-chain interoperability. At June 30, 2026, USDC in circulation was $73.3 billion, up 19% year over year, with average USDC in circulation of $76.5 billion, up 25%. USDC onchain transaction volume reached $14.8 trillion in Q2 2026, up 151% year over year.
Circle holds one of the leading positions in global fiat-backed dollar stablecoins. At Q2 2026 quarter end, it reported a 27% share of the fiat-backed U.S.-dollar stablecoin market. The company also reported 7.0 million wallets holding more than $10 of USDC, up 24% year over year. USDC on platform was $12.4 billion at quarter end, up 106%, showing stronger direct platform engagement.
Tether is Circle’s most important direct competitor. Tether’s USDT remains the largest global dollar stablecoin by circulation, especially in offshore crypto trading and emerging-market use cases. Circle’s USDC is positioned more toward regulated markets, institutional adoption, payments, tokenization and U.S.-aligned compliance. This creates a different risk and growth profile than Tether, with Circle more exposed to public-company disclosure, regulatory oversight and interest-rate-driven reserve economics.
Other competitors include fiat-backed stablecoin issuers, bank-issued token projects, tokenized money market funds, payment networks and digital-asset infrastructure providers. Visa, Mastercard and large banks are also relevant comparables because they control major payment and settlement rails, although several of them also partner with Circle.
Circle’s market position is strengthened by relationships with BNY, BlackRock, DTCC, Standard Chartered, Visa, Mastercard, ICE, Global Payments, MoneyGram, Galaxy, SBI Group and Sumitomo Corporation. These relationships cover custody, tokenization, validation, minting and redemption, settlement and infrastructure exploration. Circle Payments Network reached $14.7 billion in annualized transaction volume for the trailing 30 days at Q2 2026 quarter end, up 76% quarter over quarter, with 175 financial institutions enrolled.
China exposure appears limited. Circle does not disclose mainland China as a meaningful revenue market or operating jurisdiction. Its Asia-Pacific activity is more visible in Singapore, Japan and Korea through licensing, partnerships and commercial exploration.
Overall, Circle is a leading regulated stablecoin infrastructure company rather than a traditional payments processor or crypto exchange. Its market position depends on the growth of USDC circulation, institutional trust, payments adoption, tokenized asset activity and the economics of reserve income after distribution costs.
