On April 16, data from DefiLlama showed that the total stablecoin market capitalization officially crossed the $320 billion mark, reaching $320.007 billion. The sector recorded net inflows of approximately $2.54 billion over the past seven days, extending the robust growth trend seen in 2026. While Tether’s USDT remains the dominant player, its market share has notably declined.
USDT Dominance Falls 2.5%, USDC Steadily Gains
USDT now holds a market cap of around $185.463 billion, equivalent to 57.96% of the total stablecoin market. Although USDT still recorded $1.373 billion in net inflows over the week (up 0.75%), its market share dropped from 60.46% at the start of the year to 57.96%—a decline of 2.5%. This indicates that while USDT’s absolute size is still growing, competitors are increasingly eating into its dominance.
Circle’s USDC follows with a market cap of $78.621 billion, rising 0.55% in the week with net inflows of approximately $431 million. USDC’s steady growth reflects rising demand for compliant and transparent stablecoins.
Top Five Stablecoins Dominate with 88.47% Share
Sky’s USDS (formerly MakerDAO) ranks third with an $8.605 billion market cap, down 0.99% for the week. Ethena’s USDe sits fourth at $5.827 billion, nearly flat. Sky’s legacy stablecoin DAI rounds out the top five with $4.581 billion, posting the largest weekly decline among the leaders at 1.72%. Collectively, the top five stablecoins represent $283.097 billion, or roughly 88.47% of the total market.
Beyond the leaders, other players are making notable moves. World Liberty Financial’s USD1, PayPal’s PYUSD, BlackRock’s BUIDL, Circle’s USYC, and Ondo’s USDY have all recorded significant shifts in 2026. Many projects outside the top ten are also seeing increased activity, signaling that stablecoin demand is broadening beyond the mainstream tokens.
Outlook: Diversification and Regulation
The stablecoin market crossing $320 billion reflects continued capital flows into dollar-pegged digital assets, benefiting both centralized and decentralized platforms. Multiple consecutive weeks of positive inflows suggest strong market sentiment. However, whether this expansion can persist depends on market conditions, regulatory clarity, and how issuers respond. For now, the data points to a clear upward trend, and the growing diversification is expected to strengthen the ecosystem’s overall resilience.
