That was after the capitalization for the tokens soared $5.448 billion in the past week, and rose over 6% in the past month.
The stablecoin market also saw quarterly growth of 20% in Q3 2025, which outpaced many traditional asset classes.
Tether’s USDT Still The Dominant Stablecoin
Tether’s USDT token is still the dominant token in the stablecoin market. The DefiLlama data shows that its market cap is around $176.328 billion. This accounts for 58.35% of the stablecoin sector.
Over the past month, the stablecoin leader also saw its market cap grow more than 5%, with around a 1% gain in the last week.
Ranked as the second-biggest stablecoin by market cap is Circle’s USD Coin (USDC), which has a capitalization of $74.077 billion. Similar to USDT, USDC’s market cap rose in the past month as well, but by a smaller 2%.
Ethena’s USDe token is currently ranked as the third-biggest stablecoin. Its market cap stands at approximately $14.38 billion after the token outperformed USDT and USDC from a growth perspective in the last month and grew more than 18%.
Tether Co-Founder Says All Currency Will Become Stablecoins By 2030
The market cap for stablecoins has been in an uptrend ever since US President Donald Trump signed the GENIUS Act into law. It is one of the first pieces of legislation for digital assets on the federal level, and establishes the regulatory guidelines for stablecoin firms looking to issue their tokens in the US.
That’s amid an overall embrace of digital assets by the Trump Administration. A Trump-linked decentralized finance project called World Liberty Financial has also deployed its own stablecoin tokens this year under the ticker symbol “USD1.” In a short amount of time, the token has risen the crypto rankings to become the sixth-largest stablecoin in the market.
During an interview at the Token2049 conference in Singapore, Tether co-founder Reeve Collins said that the pro-crypto moves by the President could serve as a major catalyst for the industry.
He also predicted that all currencies will become a stablecoin by the end of the decade.
Stablecoins are already widely used for trading, payments, as well as a store of value during volatile periods. Investors often see their supply as a key indicator of how much capital is flowing into the crypto market.
Many of those tokens are pegged to fiat currencies, such as the dollar. This allows investors to reduce the amount of volatility in their portfolios.
According to the Tether co-founder, the benefits that come from transacting with money on the blockchain are too compelling for financial institutions to ignore.
“Every large institution, every bank, everyone wants to create their own stablecoin, because it’s lucrative and it’s just a better way to transact,” Collins said.
