Circle Internet Group, Inc. describes a full‑stack internet financial platform built around its USDC and EURC stablecoins, new USYC tokenized fund, and the Arc Layer‑1 blockchain. The company aims to move money over public blockchains for payments, trading, treasury, and capital markets.
USDC had more than $75 billion in circulation as of December 31, 2025, with daily transaction volumes regularly above $10 billion, and over $53.3 trillion moved between traditional banking and digital payment rails since 2018. As of March 5, 2026, Circle had 228,100,955 Class A shares outstanding.
Circle emphasizes a regulation‑first approach, with U.S. money transmission licensing, a BitLicense, and non‑U.S. authorizations in the EU, UK, Singapore, Bermuda, and Abu Dhabi. It highlights the U.S. GENIUS Act as a coming federal stablecoin regime that aligns with its reserve and disclosure practices.
Reserve assets backing USDC are kept in highly liquid instruments, including about 88% in the BlackRock‑managed Circle Reserve Fund and most of the rest as cash at global systemically important banks, with EURC fully backed by cash. The filing also details partnerships with Coinbase, Binance, and BlackRock, growing competition from other stablecoins and tokenized money‑market funds, and a workforce of roughly 1,100 employees focused on developer tools, payments applications, and interoperability services like CCTP and Gateway.
