Circle Internet's USDC stablecoin experienced a significant growth surge in 2025, outpacing its larger competitor USDT. USDC's market capitalization increased by 73% to $75.12 billion, while USDT saw a 36% rise to $186.6 billion. This trend follows a similar pattern in 2024, where USDC's growth rate was 77% compared to USDT's 50%. The growth is attributed to a more favorable stance towards digital assets by the U.S. government.
