Tether (USDT) leads the category with a market capitalization of $151.0 billion, representing 62.41% of the entire stablecoin market. It also leads in 24-hour trading volume with $87.4 billion exchanged, indicating high turnover and liquidity.

The figures reflect Tether’s persistent presence across centralized exchanges, DeFi protocols, and crypto payment infrastructure. Its market performance places it significantly ahead of all other stablecoins.

USDC is the second-largest by market cap, totaling $60.6 billion. Its daily trading volume stands at $11.1 billion. USDT and USDC comprise over 85% of the stablecoin market’s total capitalization. This level of concentration suggests that a majority of stablecoin-based activity still relies on two primary assets, even as new tokens continue to emerge.

DAI, USDe Show High Volume-to-Cap Ratios

Among decentralized options, DAI holds a market capitalization of $5.3 billion. However, its daily volume of $17.1 billion exceeds its total market value, indicating significant transaction velocity. The data suggests DAI plays an active role in short-term trading and DeFi applications, where users frequently mint and redeem the token.

Another entry is USDe, which reported a daily volume of $150.3 million with a relatively modest market cap of $4.9 billion. This high trading activity relative to its size may reflect growing short-term interest or increased integration with newer protocols.

PYUSD, in contrast, shows a different profile. Its market cap is $911.5 million, but its trading volume is comparatively low at $19.8 million. The discrepancy may be due to more limited exchange listings or less user engagement on-chain. The asset remains under observation as adoption patterns evolve.

The latest list features the USDO and USDY stablecoins. USDO is worth $647.1 million in the market, compared to USDY’s $585.4 million. This demonstrates that stablecoins are becoming more diverse, but neither currently sees significant trading.

The stablecoin business is highly centralized, and USDT and USDC own most of the shares and provide much of the liquidity. Besides, smaller and lesser-known coins are gaining popularity, hinting at possible new ways they can be used.
