Circle to Launch Arc Mainnet Amidst BlackRock and DTCC Partnerships
The firm’s new infrastructure aims to reduce reliance on third-party networks, while Q2 earnings signal improved profitability ahead of the September launch.
Stablecoin issuer Circle has confirmed that its proprietary blockchain operating system, Arc Mainnet, will launch on 16 September. The announcement coincides with the revelation of strategic partnerships with the Depository Trust & Clearing Corporation (DTCC) and asset manager BlackRock, signalling a push toward institutional-grade infrastructure for digital asset finance.
Arc is an open Layer-1 blockchain designed specifically for stablecoin-native financial applications. Unlike general-purpose networks such as Ethereum or Solana, the platform is built to support payments, foreign exchange, treasury management, and tokenised real-world assets. The initiative allows Circle to retain control over core infrastructure while reducing its dependence on third-party blockchains.
A key differentiator for Arc is its ability to use USDC as the native gas token. This eliminates the need for businesses to hold volatile cryptocurrencies to cover transaction fees, providing predictable costs in dollar terms. The network also offers deterministic settlement finality in under one second and includes opt-in privacy features to maintain auditability for compliance purposes.
Early adoption metrics from the Arc testnet have been robust. Circle reported that over 100 companies joined the ecosystem, which processed more than 150 million transactions in its first 90 days. The testnet attracted nearly 1.5 million transacting wallets and maintained average settlement times of approximately 0.5 seconds, demonstrating the platform's capacity for high-volume processing.
Financially, Circle’s second quarter of 2026 results exceeded street expectations. Total revenue reached $701 million, a 7% increase year-on-year, driven by a 19% rise in USDC in circulation to $73.3 billion. The company reported earnings per share of $0.18, surpassing the consensus estimate of $0.16, and expanded its Revenue Less Distribution Costs margin to 41%.
The firm holds a cash balance of $75.78 billion, including $72.9 billion in deposits from stablecoin holders. Despite the positive earnings beat, CRCL shares are down 14% year-to-date, although the stock has doubled since its initial public offering in June 2025.
Analysts maintain a "Moderate Buy" consensus on CRCL, with a mean target price of $101.70. This valuation implies an upside potential of approximately 51% from current levels. The rating is supported by 11 "Strong Buy" recommendations, 13 "Hold" ratings, and one "Moderate Sell" among the 27 analysts covering the stock.
Competition remains a factor, with frameworks such as Open USD, backed by a consortium including Coinbase and Shopify, challenging USDC’s market dominance. Success for Arc will depend on whether developers and enterprises choose the new network over established blockchains and competing stablecoin standards.
