USDT and USDC Dominate Stablecoin Market with Combined Value of Nearly $258 Billion

The stablecoin market has seen significant consolidation, with Tether's USDT and Circle's USDC holding nearly $258 billion in combined value. According to Coin Bureau, USDT accounts for roughly 60% of this total, with a market value of approximately $183.4 billion, while USDC holds around $74.5 billion. This leaves less than $53 billion for all other stablecoin competitors.

The dominance of USDT and USDC has significant implications for crypto-market liquidity, as these assets are widely used across exchanges, blockchain networks, and digital-asset applications. Changes in their circulating supply can have a broader effect on available dollar liquidity throughout the market.

The concentration of stablecoin market share is also attracting regulatory attention. The 2025 GENIUS Act established a federal framework for payment stablecoins, with requirements governing issuers and reserve arrangements. This shift in regulation may influence how stablecoin companies compete for market share as the sector expands.
