$USDC issued by Circle, has significantly increased its market share in the stablecoin sector, rising from 20% to 25.5%, while the share of USDT has decreased to 65.4%. This growth is attributed to USDC's regulatory compliance, strategic partnerships, and expansion on networks like Solana, where $6 billion was minted in January 2025. In 2024, USDC processed over $20 trillion in transactions, with a 78% increase in circulating supply. These developments position USDC as a strong competitor to USDT in the stablecoin market.
