Tether’s USDT briefly overtook Ethereum on June 26, reaching about $186.06 billion in market capitalization, just ahead of Ethereum by roughly $400 million. The crossover marked the first time a dollar-pegged stablecoin surpassed Ethereum by valuation, pointing to a shift in where capital was sitting inside crypto at that moment.
USDT’s market cap rises when more tokens are issued to meet demand for on-chain dollar liquidity, while Ethereum’s market cap moves with the price of ether. So this wasn’t just about Ethereum losing ground. Traders and crypto-native firms kept stablecoin demand strong, choosing tokenized dollars over taking on new price exposure, while ether’s market value fell back during a broader sell-off.
Tether continues to publish USDT circulation and reserves data, highlighting how much the stablecoin’s growth has become about balance-sheet scale as well as utility. Ethereum remains central to much of DeFi and tokenized assets, but this flip showed that, during the crossover, liquidity was leaning toward stable, easily redeployed assets.
