Circle Internet Group: Building the Financial Infrastructure of the Future

Circle Internet Group has become one of the most talked-about names in fintech, despite being relatively unfamiliar to many investors. The company's core business is centered around USDC, a stablecoin designed to maintain a value of $1.

Unlike traditional dollars or Bitcoin, USDC aims to provide a stable store of value for moving and storing money across blockchain networks. Circle issues USDC and backs the tokens with highly liquid reserves, including cash and short-term U.S. government securities.

The company's unusual business model relies on earning interest income from the assets backing its stablecoin. In 2025, reserve income accounted for 96% of Circle's total revenue, highlighting the importance of interest rates to the business.
