US Dollar-Pegged Stablecoins Remain Steady at $303.4 Billion Amid Market Dynamics

The total market capitalization for US dollar-pegged stablecoins has been reported at $303.4 billion as of mid-October 2026, according to data from CoinGecko. This figure reflects a slight decrease of 0.56% from the previous week, with the overall stablecoin supply experiencing a growth of approximately 1.4% over the last 90 days.

Within the USD stablecoin market, Tether’s USDT continues to dominate, holding about 60.6% of the total supply, valued at approximately $184.1 billion. Circle’s USDC follows as the second-largest player, accounting for roughly 23.9% of the market, with a valuation around $72.6 billion.

In contrast, the market for euro-pegged stablecoins remains significantly smaller, totaling only $810.1 million. This stark difference underscores the overwhelming preference for US dollar-backed tokens in the cryptocurrency landscape.

As the stablecoin market fluctuates between $300 billion and $313 billion, the reliance on Tether and Circle raises concerns about potential regulatory impacts or operational challenges that could influence liquidity across the broader market.
