Overview
- Tether's USDT moved above Ethereum in some headline measures during a sharp market sell-off on Friday, June 26, with reports citing an intraday market-cap reading near $186.06 billion versus ETH near $185.66 billion and a fully diluted valuation flip in some data feeds.
- The crossover was temporary and driven mainly by ETH's price falling into the $1,500–$1,600 range while USDT supply held steady, so Ethereum later recovered its position by circulating market cap.
- Tether's scale is notable because the firm reported over $193 billion in reserves by mid‑2026 and said 2025 profits exceeded $10 billion, facts that magnify its systemic importance and invite regulatory attention.
- The event highlights how traders use stablecoins as on‑chain dollar liquidity during downturns and contrasts with stress in the Ethereum ecosystem, which has seen near‑term price weakness and reported staff reductions at the Ethereum Foundation even as some treasuries bought or staked ETH.
- What to watch next: whether ETH can rebuild distance above USDT in market value, whether stablecoin supply begins to shrink through redemptions, and how regulators respond to scrutiny of Tether's reserve backing.
