Tether's USDT became larger than Ethereum by market capitalization on June 26, 2026, according to data shared by Cointelegraph. USDT stood at $186.06 billion against ETH's $185.66 billion, a crossover of less than half a billion dollars but a first for a stablecoin against the second-largest crypto asset.
The gap is thin and could close again within hours. The direction of travel is what matters. A dollar-pegged token, whose price barely moves, now ranks above an asset that has anchored the smart-contract economy since 2015.
A dollar token edges past the second-largest crypto asset
For most of crypto's history the top of the market cap table read the same way: Bitcoin first, Ethereum second, with stablecoins and exchange tokens further down. USDT crossing ETH reshuffles that order at the number two position. By the snapshot used here, USDT's $186.06 billion supply now exceeds the combined value of every circulating ether token.
This is a market-structure marker rather than a price call. USDT is not appreciating. Its market cap is the dollar value of coins in circulation, and that figure climbs when more USDT is minted, not when its price rises. ETH's market cap moves with its price. The flip happened where those two lines met.
The selloff did most of the work
ETH did the heavy lifting on the downside. Ether traded at $1,537.09 on June 26, 2026, down 4.89% over 24 hours and 9.78% over the prior week, per live market data at the time of writing. That drawdown shaved tens of billions off ETH's market cap and dragged it under the USDT line.
The wider tape was red. Bitcoin sat at $58,722, off 3.39% on the day, while XRP fell 5.05% and SOL slipped 1.86%. The Crypto Fear and Greed Index printed 14, deep in extreme fear territory. When sentiment sinks this far, capital often rotates out of volatile assets and parks in dollar stablecoins, which compresses ETH's valuation and inflates the stablecoin float at the same time. Both forces push in the same direction for a flip like this one.
USDT's growth tells the other half
The selloff explains the timing, not the trend. USDT has spent two years expanding its float as trading desks, payment firms, and offshore users adopted it as a settlement layer. A token reaching $186 billion in circulation means roughly that much real demand to hold dollars on-chain, much of it outside the United States where dollar access is harder to come by.
That demand is the durable part of the story. Even if ETH rebounds tomorrow and reclaims the number two slot, USDT has reached a scale where it now rivals the entire ether market. A stablecoin sitting at this size also reshapes the collateral base of crypto: more of the system's value is denominated in dollars that do not swing with the market, which dampens some volatility and concentrates more counterparty exposure in a single issuer.
This is not the first flip of its kind in recent weeks. RLUSD's supply recently moved more onto the XRP Ledger than Ethereum, another sign that stablecoin spending and settlement are migrating across chains rather than staying anchored to a single network.
Stablecoin rails hold up when prices fall
For anyone funding a card from crypto, a milestone like this is a reminder of where the spending layer actually sits. A large share of crypto card transactions clear in USDT or USDC behind the scenes, even when the headline asset is BTC or ETH. During a drawdown, a card funded directly from a stablecoin balance avoids selling a falling asset at the till, where the conversion spread and the network markup stack on top of an already poor price.
That is the practical edge of stablecoin-denominated spending versus selling volatile holdings under pressure. Cards that let you spend from your own wallet in a stablecoin keep the funding asset stable and the timing in your hands. The trade-off is concentration: holding USDT means trusting one issuer's reserves, so the size milestone cuts both ways for users who lean on it.
Overview
USDT's market cap reached $186.06 billion on June 26, 2026, edging past Ethereum's $185.66 billion for the first time as ETH fell 4.89% in a day during a broad selloff with the Fear and Greed Index at 14. The margin is narrow and may reverse, but the crossover marks USDT's growth into an asset that now rivals the second-largest network in crypto, and it underscores how much of the market's value has shifted into dollar stablecoins.
