Circle Posts $701M Q2 Revenue as USDC Circulation Hits $73.3B
Circle reported $701 million in Q2 2026 revenue and reserve income, a 7% increase year over year, as circulation of its USDC stablecoin grew 19% to $73.3 billion. The company also disclosed that onchain transaction volume jumped 151% to $14.8 trillion, while adjusted EBITDA rose 8% to $143 million.
The figures, released in Circle’s quarterly financial summary on August 5, 2026, underscore the stablecoin issuer’s continued expansion despite a competitive market that includes Tether’s USDT and new entrants from traditional finance.

Key Metrics Point to Accelerating USDC Adoption
Circle’s Q2 results show steady growth across its core business. The 19% increase in USDC circulation brings the stablecoin’s total supply to $73.3 billion, a notable rebound from the market slump of 2023 when circulation fell below $25 billion.
According to the company’s report, the 151% surge in onchain transaction volume to $14.8 trillion reflects deeper integration of USDC in decentralized finance protocols, cross-border payments, and tokenized asset settlements. This metric includes transactions across multiple blockchain networks where USDC is issued, including Ethereum, Solana, and several Layer 2 networks.

Adjusted EBITDA of $143 million, up 8% from the prior year, indicates that Circle’s revenue growth is translating into improved profitability, even as the company invests in new product lines and regulatory compliance infrastructure.
Arc Mainnet Launch Set for September
Circle also used the quarterly update to confirm that its Arc public mainnet will launch on September 16, 2026. Arc is designed to support privacy features, programmable finance, and tokenized real-world assets, positioning Circle to compete in the institutional blockchain space.
The company said more than 100 ecosystem and institutional builders are already participating in Arc’s development, suggesting that the platform has attracted meaningful early interest from financial institutions and technology partners. Arc’s focus on privacy and programmability could differentiate it from public networks like Ethereum, which face scalability and confidentiality limitations.
Circle’s move into a dedicated blockchain network follows similar initiatives by other major crypto firms, including Coinbase’s Base network and Kraken’s Ink, as stablecoin issuers and exchanges seek to capture more of the onchain value chain.
What This Means for the Stablecoin Market
Circle’s Q2 results arrive amid a rapidly evolving regulatory environment for stablecoins. The European Union’s Markets in Crypto-Assets (MiCA) regulation has been fully applicable since mid-2025, and Circle was among the first issuers to secure a MiCA license, giving USDC a compliance advantage in the region.
In the United States, the GENIUS Act, signed into law in 2025, established a federal framework for payment stablecoins. Circle has been an active proponent of the legislation, which requires issuers to maintain one-to-one reserves and undergo regular audits.
The growth in USDC circulation and transaction volume suggests that regulated stablecoins are gaining share in a market once dominated by offshore issuers. However, competition remains intense, with Tether continuing to hold a larger overall market share, and traditional financial institutions such as PayPal and JPMorgan expanding their own digital currency offerings.
For investors and market observers, Circle’s financial disclosures provide a rare window into the economics of a major stablecoin issuer. The company’s revenue model, which relies primarily on interest income from reserve assets, remains sensitive to interest rate movements. If the Federal Reserve continues to cut rates, Circle’s reserve income could face pressure in future quarters.
Circle has also been open about its plans for a potential initial public offering, though no specific timeline has been announced. The company previously attempted to go public via a SPAC merger in 2022, a deal that was ultimately abandoned.
As the September 16 Arc mainnet launch approaches, market participants will be watching whether Circle can translate its stablecoin dominance into a broader blockchain platform business. The company’s ability to attract institutional builders and support real-world asset tokenization will be key indicators of its long-term strategy.
