Circle, the issuer of USDC, is showing signs of transitioning from an interest-driven financial company to a fee-based digital dollar infrastructure. USDC, the second-largest stablecoin with a $77 billion supply, is increasingly used for payments and settlements, as evidenced by a 247% surge in on-chain transaction volume in FY2025. This shift is further highlighted by USDC surpassing USDT as the largest settlement asset, accounting for 64% of real economic settlement volume. Circle's revenue structure is evolving, with new income streams from the Circle Payments Network and Cross-Chain Transfer Protocol. The Circle Payments Network, launched in May 2025, has reached an annualized transaction volume of $5.7 billion, while the Cross-Chain Transfer Protocol processed $41.3 billion in Q4 2025. Additionally, "Other Revenue" from subscription services and trading has grown significantly, indicating a move towards non-interest income. The potential for Circle's valuation to increase hinges on several factors, including the growth of USDC's circulating supply, the frequency of its use, and the expansion of revenue beyond interest. As these metrics improve, Circle's transformation into a digital dollar infrastructure network becomes more apparent, positioning it for substantial growth.
