USDT and USDC Control $258 Billion of the Stablecoin Market

Tether’s USDT and Circle’s USDC have strengthened their dominance of the stablecoin market, with the two assets collectively holding $258 billion in market value, to figures cited by Coin Bureau.

USDT accounts for $183.4 billion, representing roughly 60% of the overall stablecoin market, while USDC holds $74.5 billion. Combined, the two stablecoins leave less than $53 billion for all other competitors, underscoring the concentration of liquidity among the industry’s two largest dollar-pegged assets.

Tether USDT Maintains Clear Market Leadership

Tether remains the largest stablecoin issuer by a wide margin. Recent market data places USDT's supply at around $183 billion, more than twice the size of USDC, while estimates of USDT’s market share remain close to 60% of the total markets.

USDC, issued by Circle, occupies the second position with $74.5 billion in the figures cited by Coin Bureau. The gap between the two leading assets and the rest of the sector remains substantial, with no other individual stablecoin approaching either issuer’s scale.

The concentration has important implications for crypto-market liquidity. USDT and USDC are widely used across exchanges, blockchain networks and digital-asset applications, meaning changes in their circulating supply can have a broader effect on available dollar liquidity throughout the market.

World Liberty Financial USD1 Moves Ahead of PayPal USD

The rankings also highlight the rapid rise of World Liberty Financial’s USD1 stablecoin, which Coin Bureau places at $4.3 billion and sixth overall. At that level, USD1 has moved ahead of PayPal USD, although market rankings can change as circulating supplies fluctuate.

Current market trackers similarly place USD1 at approximately $4.3 billion, while PayPal USD remains below $3 billion.

The growing size of the stablecoin sector is also attracting greater regulatory attention. In the United States, the 2025 GENIUS Act established a federal framework for payment stablecoins, with requirements governing issuers and reserve arrangements. The regulatory shift is expected to influence how stablecoin companies compete for market share as the sector expands.

For now, the central question for the market is whether newer issuers can meaningfully challenge the entrenched dominance of USDT and USDC as regulated stablecoin adoption accelerates.
