Goldman Sachs Issues Warning on Circle Costs Despite Blowout USDC Earnings

Circle Internet Group (CRCL) has delivered a quarterly performance that sets a new benchmark for the stablecoin industry, reporting a clean earnings beat characterized by a 77% year-over-year surge in total revenue and reserve income to $770 million. This growth was primarily fueled by the expansion of USD Coin (USDC), which saw its circulation rise 72% to $75.3 billion. The company’s ability to convert this scale into a 54% adjusted EBITDA margin—reaching $167 million for the period—initially painted a picture of a high-margin, high-growth financial powerhouse. However, a 'first take' analysis from Goldman Sachs has introduced a significant caveat to this narrative, warning that Circle’s 2026 cost structure may be far more burdensome than current models suggest.

The core of Circle’s success remains its reserve-driven model. As a regulated stablecoin pegged 1:1 to the U.S. dollar, USDC generates income by investing its reserves in short-term U.S. Treasuries and other liquid assets. With on-chain transaction volume skyrocketing 247% to a staggering $11.9 trillion, the utility of USDC as a settlement layer for global finance is no longer theoretical. This adoption has been significantly bolstered by the GENIUS Act framework, which provided the regulatory clarity necessary for institutional players to integrate USDC into their operations. The legislative tailwind has effectively separated USDC from less-regulated competitors, positioning it as the preferred choice for compliant digital dollar transactions.

Despite these record-breaking metrics, Goldman Sachs analysts highlighted a 'cost story' buried within the company’s 2026 guidance. The investment bank suggests that as Circle matures and the regulatory environment under the GENIUS Act becomes more stringent, the operational costs associated with compliance, security, and infrastructure will 'normalize' at a higher level. This normalization implies that the current 54% EBITDA margin may be a peak rather than a baseline. Investors are now being cautioned to look beyond the top-line growth and consider the long-term sustainability of these margins as Circle transitions from a growth-focused startup to a mature, highly regulated financial institution.
