USDT Briefly Flips ETH As Tether Market Cap Tops Ethereum

USDT briefly overtook ETH to become the second-largest crypto asset by market cap, with Tether reaching about $191.5 billion against Ethereum near $187.5 billion during the move.

The brief flip came as ETH fell about 5% on the day, cutting Ethereum’s market value below Tether’s dollar stablecoin supply for a short period. Market coverage captured the USDT crossover as Ethereum slipped and Tether’s market value held near the upper end of the stablecoin sector.

Ethereum later moved back above USDT in live rankings, but the temporary flip marked a rare moment in crypto market structure. ETH has long held the No. 2 position behind Bitcoin, while USDT has grown into the largest dollar-pegged asset used across centralized exchanges, DeFi markets and cross-chain settlement.

Ethereum Selloff Narrows The Ranking Gap

The ranking changed because Ethereum’s market cap dropped while USDT’s market cap stayed large. ETH’s valuation moves with the token price, while USDT’s market cap mainly reflects the number of tokens issued near the $1 peg.

Ethereum market data later placed ETH near $1,560 after a 24-hour decline of more than 5%. Live Tether market data placed USDT close to $1, with market value still near the mid-$180 billion range and fully diluted value around $191.5 billion.

That left Ethereum back in second place, but only after USDT had briefly moved ahead during the session. The move showed how fast the No. 2 ranking can change when ETH sells off and stablecoin supply remains elevated.

USDT’s scale has also become a major measure of crypto liquidity. Tether’s transparency data tracks issued supply across supported networks, while market trackers continue to show USDT as the largest stablecoin by a wide margin.

Tether’s Size Puts Pressure On ETH’s Long-Held Rank

USDT challenging Ethereum’s ranking reflects the growing weight of stablecoins inside the crypto market. Traders use USDT for exchange balances, collateral, settlement, cross-border transfers and temporary dollar exposure, giving the token a market value that can rival major network assets during selloffs.

The moment also followed earlier pressure around stablecoin liquidity after USDT’s market cap pulled back from recent intraday levels. The new flip showed a different setup, with Tether’s market value staying large enough to briefly move ahead of ETH while Ethereum weakened.
