Stablecoin Market Cap Surpasses $283.4 Billion, USDT Dominates with 59.12% Share

The total market capitalization of stablecoins has grown by 2.63% in the past 7 days, reaching $283.4 billion. USDT holds a 59.12% market share.

The total market capitalization of stablecoins has grown by 2.63% in the past seven days, reaching $283.4 billion. This growth is driven by various factors, including regulatory developments and increased institutional adoption. As of July 2, 2025, USDT holds a 59.12% market share, indicating a significant presence but a slight dip from its previous dominance.

Tether's USDT, once the dominant stablecoin, has seen its market share drop below 60% for the first time since March 2023. This shift is attributed to increased competition from other stablecoins and traditional financial firms entering the market. Circle's USDC, for instance, has seen its market share grow, albeit remaining significantly smaller than USDT's. The GENIUS Act, passed in July 2025, has also played a role in this dynamic by encouraging more institutional participation and expanding the market.

The stablecoin sector has been growing rapidly, with the total market capitalization reaching a new high of $283 billion. This growth is supported by a variety of factors, including the passage of the GENIUS Act, which has opened the door for more stablecoin issuers and users. The act mandates supervision, reserve requirements, disclosure, and illicit finance controls, which are expected to shape the future of the stablecoin market.

Despite losing ground, Tether remains the sector's largest issuer by a wide margin. As of press time, USDT maintains a market capitalization of $168 billion, which is twice that of Circle's USDC, its closest rival. This dominance is likely to persist due to Tether's established reputation and widespread adoption.

The regulatory environment is expected to continue shaping the stablecoin market. The Treasury has opened a public comment window to develop the rulebook for stablecoins, which could influence product design and user incentives. The GENIUS Act, along with other regulatory developments, is likely to accelerate institutional adoption and expand the market well beyond its current size.

In summary, the stablecoin market has shown significant growth in the past seven days, reaching a new high of $283.4 billion. While Tether's USDT remains the dominant stablecoin, increased competition and regulatory developments are reshaping the market landscape.
