USDT (Tether) remains the largest stablecoin by market cap and liquidity, dominating the stablecoin sector and serving as the main liquidity rail on exchanges and DeFi.

USDC (USD Coin) continues to gain ground, with its market cap recently surpassing $56 billion — a multi‑year record driven by regulatory compliance and broader adoption.

The stablecoin market overall is expanding, with net inflows up significantly and total supply increasing amid broader crypto market activity.

📊 USDC vs USDT – Key Dynamics

Peg & Stability

Both USDC and USDT are designed to maintain a 1:1 peg to the U.S. dollar — meaning their price normally stays very close to $1.00.

Temporary deviations (tiny premiums/discounts) can appear in certain markets/exchanges but are usually corrected quickly by arbitrage.

Market Position

USDT still leads in sheer volume and usage across exchanges and DeFi due to long‑standing network effects.

USDC is growing faster proportionally and attracting institutional interest thanks to stronger regulatory compliance and transparency.
