USDT and USDC Lead $46B Stablecoin Inflows in Q3 as Demand Surges

Stablecoins posted $45.6 billion in inflows in Q3 2025, a 324% jump from Q2, led by USDT, USDC, and Ethena’s USDe. Ethereum continues to dominate stablecoin issuance, while other usage metrics like active addresses and transfer volumes showed declines despite record growth.

Stablecoins saw explosive growth in the third quarter of 2025, with net inflows soaring more than 324% from the previous quarter. Data from RWA.xyz shows that inflows jumped from $10.8 billion in Q2 to $45.6 billion in Q3, fueled largely by Tether’s USDT, Circle’s USDC, and the rapid rise of Ethena’s synthetic stablecoin USDe.

Tether’s USDT led the pack with $19.6 billion in new issuance, maintaining its dominant position in the market. Circle’s USDC followed with $12.3 billion in inflows, a sharp increase compared to just $500 million in the previous quarter. Ethena’s USDe, which has quickly established itself as a significant player in the stablecoin market, recorded $9 billion in net inflows.

Other issuers also gained traction. PayPal’s PYUSD saw $1.4 billion in inflows, while MakerDAO’s USDS attracted $1.3 billion. Ripple’s RLUSD and Ethena’s USDtb posted steady gains, underscoring growing competition in the stablecoin sector.

Stablecoin Growth Outpaces Q2 by Wide Margin

Over the past six months, total stablecoin inflows hit $56.5 billion, with the bulk concentrated in Q3. Tether continued to dominate across both quarters, while USDC’s resurgence highlighted increasing demand from institutional and retail users alike.

Ethena’s USDe was another standout story, with nearly all of its $9 billion inflows occurring in Q3, compared to just $200 million the previous quarter. Analysts suggest that synthetic and algorithmic stablecoins may increasingly capture market share, especially during periods of heightened demand for yield and liquidity.

Ethereum Retains Stablecoin Crown

Ethereum remains the leading blockchain for stablecoins, hosting roughly $171 billion in circulating supply. Tron ranks second with $76 billion, while Solana, Arbitrum, and BNB Chain together account for about $29.7 billion.

By token, USDT still dominates with nearly 59% of the market, followed by USDC at 25%. Ethena’s USDe has climbed rapidly, capturing close to 5% of the market.

Despite the surge in inflows and market cap growth — which reached $290 billion in the last 30 days — other metrics have softened. Monthly active addresses fell 22.6% to 26 million, while transfer volume dipped 11% to $3.17 trillion, suggesting that while investors are parking capital in stablecoins, overall on-chain activity is cooling.
