Circle Internet Group is preparing for the September 16, 2026, launch of its Arc mainnet, a Layer 1 blockchain designed for stablecoin-based transactions, real-time fund transfers, and tokenized assets. To maintain price stability for institutional users, the network will utilize USDC for transaction fees. 

A diverse cohort of major financial institutions serves as founding validators, including BlackRock, Visa, Mastercard, Standard Chartered, MoneyGram, Intercontinental Exchange (ICE), DTCC, Galaxy Digital, Global Payments, SBI Group, and Sumitomo Corporation. BlackRock intends to deploy its $2.87 billion BUIDL fund on the network, while DTCC plans to begin tokenizing assets on Arc in 2027.

In anticipation of the launch, Circle’s stock price rose by 9.65%. Additionally, Circle has deepened cooperation with edgeX, which is set to serve as the primary platform for perpetual trading on the network following the launch. This partnership aims to develop on-chain foreign exchange and global asset trading markets, including USD/JPY perpetual contracts. The announcement triggered a 28.2% price increase for the EDGE token, though market data noted significant profit-taking.

The broader stablecoin market has reached a capitalization of approximately $304 billion. While Tether (USDT) holds a 60.31% market share, USDC yields vary across lending platforms, such as Aave v3 and Morpho. Regulatory scrutiny persists, specifically regarding potential U.S. prohibitions on interest or profit payments directly linked to holding stablecoins for payment purposes.
