USDC Circulation Surges 19% As Circle Q2 Revenue Hits $701 Million

• Circle reported $701 million in Q2 2026 revenue and adjusted EBITDA of $143 million, driven by 19% year-over-year USDC circulation growth.
• USDC circulation reached $73.3 billion, with on-chain transaction volume surging 151% to $14.8 trillion, highlighting expanded institutional utility.
• Circle secured a federal trust bank charter and announced September mainnet launch of Arc, a blockchain infrastructure network featuring major validators like BlackRock and DTCC.
• Visa data indicates USDC captured 70% of adjusted stablecoin transaction volume in H1 2026, shifting dominance from trading utility to regulated payment infrastructure.

Circle Internet Group reported second-quarter 2026 financial highlights that underscored the accelerating adoption of its USDC stablecoin across global markets. The company achieved total revenue of $701 million, representing a 7% year-over-year increase, while adjusted EBITDA grew 8% to $143 million . Net income reached $48 million, a significant improvement from the prior year largely due to the absence of IPO-related stock-based compensation expenses .

The growth in financial performance was directly correlated with a 19% year-over-year expansion in USDC circulation, which reached $73.3 billion at the end of the quarter . Average circulation during the quarter stood at $76.5 billion, up 25% year-over-year, providing a larger reserve pool on which the company could earn interest.

The reserve return rate was 3.5%, down 66 basis points from the previous year, yet reserve income still increased by 5% to $668 million . This demonstrates that revenue is primarily tied to the size of the reserve pool rather than the frequency of transactions .

On-chain activity further validated the expanding utility of the stablecoin. Quarterly on-chain transaction volume surged 151% to $14.8 trillion, indicating robust usage for settlements, remittances, and trading activity .

This substantial increase in transaction volume suggests that USDC is increasingly utilized for real-world financial applications rather than merely serving as a speculative store of value .

How Is Circle Expanding Beyond Stablecoin Issuance?

Circle is strategically pivoting toward comprehensive financial infrastructure beyond simple stablecoin issuance. The company raised its 2026 non-reserve revenue guidance to between $310 million and $330 million, nearly doubling previous forecasts .

This category encompasses revenue from Circle's digital finance platform, including payments infrastructure, tokenization services, and other products surrounding USDC . The company also increased its full-year Revenue Less Distribution Costs margin outlook to 41.7%-43.7% .

A key component of this strategy is the public mainnet launch of Arc, scheduled for September 16. The network features privacy capabilities and an agent stack for programmable finance .

Arc has secured founding validators including BlackRock, DTCC, Galaxy, ICE, Mastercard, and Visa . Major integrations are underway, with BlackRock planning to deploy its BUIDL fund on Arc and DTCC enabling tokenization of DTC-custodied assets .

Additionally, Circle launched the Agent Stack, hosting over 900 paid services with 99.3% of x402 agent-payment volume settling in USDC .

Regulatory advancements have also bolstered Circle’s market position. In July 2026, Circle received final approval from the U.S. Office of the Comptroller of the Currency to establish Circle National Trust .

This federally regulated national trust bank charter allows for digital asset custody and future management of the USDC Reserve . Circle also received a limited-purpose trust charter from the New York Department of Financial Services, granting authority to offer fiduciary and custody services .

Why Is USDC Gaining Ground Over Tether in Transaction Volume?

USDC has emerged as the dominant stablecoin by transaction activity, capturing approximately 70% of adjusted stablecoin transaction volume in the first half of 2026 . In contrast, Tether’s USDT represented about 25% of adjusted volume .

Visa’s analysis excluded exchange transfers, bot activity, and non-economic blockchain transactions, providing a more accurate picture of real-world stablecoin usage . Adjusted stablecoin transaction volume reached a record $1.79 trillion in June 2026 .

The growing dominance of USDC is closely tied to institutional adoption, with banks and financial institutions integrating USDC into payment, settlement, and treasury operations . Recent expansions by institutions like BNY and Standard Chartered reinforce Circle’s position as the preferred settlement asset .

Ethereum continues to host approximately 68.8% of the total $72 billion USDC supply, leveraging deep liquidity in lending protocols and decentralized exchanges . Solana hosts around $7 billion, roughly one-seventh of Ethereum’s volume .

Circle’s Cross-Chain Transfer Protocol (CCTP) allows native USDC issuance across 35 blockchains, reducing smart contract risk associated with bridged tokens . This expansion is critical for contesting Tether’s market share on newer networks .

The passage of the US GENIUS Act has further encouraged institutional participation by establishing a federal regulatory framework for payment stablecoins . Meanwhile, Tether continues to dominate trading activity on exchanges but faces regulatory challenges in jurisdictions like Europe’s MiCA framework .

Despite a second-quarter earnings miss with EPS of $0.18 against estimates of $0.27, Circle maintained a 40% compound annual growth rate target for USDC circulation through 2026 .
