Stablecoin market cap surpasses $300 billion for first time amid crypto rebound

The total market capitalization of stablecoins has surpassed $300 billion for the first time — a new all-time high for the sector amid rising activity across crypto markets.

According to real-time data from DeFiLlama, the combined value of all stablecoins now stands at $301 billion — a 2% increase over the past week and a 6.5% jump in the last 30 days.

Tether’s USDT continues to dominate the stablecoin niche, maintaining a 58% market share with a capitalization of $176.3 billion — up from $173 billion just a few days ago.

Trailing behind is Circle’s USDC at $74 billion (24.5% dominance), followed by Ethena's USDe ($14.8 billion) and MakerDAO’s DAI ($5.0 billion).

Stablecoins are widely used for trading, payments, and as a store of value during volatile periods, making their supply a key indicator of capital flows into the cryptocurrency market. Pegged to fiat currencies like the U.S. dollar, they mitigate the wild price swings that affect assets like Bitcoin, serving as a store of value during volatile periods and as a primary medium for crypto trading, DeFi apps, and cross-border payments.

The stablecoin market is showing signs of maturation, even as it continues to accelerate. The sector’s 20% quarterly growth in Q3 2025 outpaced many traditional asset classes, driven by renewed institutional interest and policy tailwinds, such as the U.S. GENIUS Act, which promises clearer regulatory pathways for dollar-pegged tokens.

This comes amid a broader crypto market rebound, with Bitcoin and Ethereum posting double-digit gains in Q3 2025 and drawing fresh capital inflows. Over the past week, Bitcoin has posted a 9.6% gain, climbing to $119,972 amid a market capitalization of $2.4 trillion, according to The Block's price page . Ethereum has jumped even more strongly, surging 13.3% to $4,498.57, with a market cap of $542 billion.
