This was not a one-off event. A long-dormant early Ethereum investor sold 55,000 ETH and 9,442 wstETH for roughly $136 million in late May, adding to the pressure near the $2,000 level .

2. Sustained Spot ETF Outflows

U.S. spot Ethereum ETFs recorded net outflows for 17 consecutive days earlier in June, pushing ETH to around $1,735 by June 5—its lowest sustained level in over two years . The outflows continued through the month:

• First week of June: ETF outflows hit $173 million, with BlackRock's ETHA alone shedding $125 million .
• Seven-day streak ending June 26: A seventh consecutive day of outflows totaled $12.85 million on June 26, with BlackRock's ETHA accounting for the entire day's redemptions. The other nine ETFs recorded zero net flows. The seven-day streak cumulatively reached approximately $95 million .
• Individual daily outflows were sizable through late June: $66 million on June 22, $82.35 million on June 23, $30.24 million on June 24, and $81.87 million on June 25 .

The sustained institutional selling removed a key source of demand that had previously helped stabilize ETH prices.

3. Historic Milestone: Tether (USDT) Flips Ethereum in Market Cap

On June 26, 2026, Tether's USDT surpassed Ethereum in market capitalization for the first time. USDT stood at $186.06 billion versus ETH's $185.66 billion—a gap of less than $400 million . The flip was driven by a 5.2% intraday drop in Ethereum's price, which pushed its market cap below $185 billion as ETH touched $1,510 on Coinbase .

The crossover was temporary—Ethereum quickly recovered above $1,560 and reclaimed the #2 spot with a market cap of roughly $189 billion —but the symbolism was stark. It ended seven straight years of Ethereum holding that ranking unchallenged and signaled how severely capital was rotating out of risk assets .

4. Price Action and Critical Support Levels

• Ethereum hit an intraday low of $1,510 on Coinbase on June 25-26, its lowest level of 2026, before bouncing above $1,560 . As of June 29, ETH was still meandering in the $1,500 region .
• Over $180 million in market-wide crypto liquidations occurred in a single 24-hour period, overwhelmingly from long positions .
• Analysts flagged $1,583 as critical volume support. If that level fails, the next downside targets are a cycle low between $1,237 and $1,089 . Citi has a $1,198 forecast for ETH if $1,500 support breaks .
• Prediction markets on Polymarket and Kalshi assigned a 73%–76% probability that ETH would hit $1,500 before the end of 2026 .

5. Broader Macro Environment

The selloff occurred against a backdrop of escalating US-Iran geopolitical tensions over the weekend of June 27-28, which pressured all risk assets . A broader macro rotation from risk assets into dollar-denominated instruments pulled capital out of cryptocurrencies generally, with Ethereum the hardest hit among large-cap tokens.

Ethereum's market dominance dropped to roughly 8.76%—down sharply from the 18–20% range it held in previous cycles .

A note on data verification: The claim that the total net asset value of U.S. spot Ethereum ETFs fell from $9.44 billion to $8.379 billion during June could not be independently confirmed from available sources. The directional trend of NAV erosion following sustained outflows is well-supported, but exact opening and closing figures for the month require direct ETF provider data.
