Is Ethereum Back? $900M Whale Bet Surges as ETH Dominance Turns Bullish

A major crypto whale added to a large Ether long as Ethereum’s market share held a key level on chart data. Together, the moves kept attention on whether ETH can keep gaining traction against the wider market.

Arkham says Hyperunit Whale added to a large Ether long

Arkham said the “$10B Hyperunit Whale,” which it links to Garrett Jin, increased an existing Ether long by another $66.2 million. In the same post on X, Arkham said the whale’s ETH long now totals about $733.3 million, while the combined long exposure across ETH, SOL, and BTC tops $900 million.

The Arkham dashboard for the labeled entity “HyperUnit BTC Whale” showed a portfolio value of about $3.33 billion at the time of the screenshot. The holdings table listed roughly 30.664K BTC valued near $2.91 billion, alongside about 126.425K AETHWETH worth roughly $415.36 million, with smaller balances shown in other tokens.

Arkham also highlighted the scale of the position by asking whether this could become the first $1 billion long since James Wynn. Arkham did not publish additional details in the post about venue, leverage, or liquidation levels for the reported long exposure. Source: Arkham Intelligence, X.

ETH dominance holds a key level as momentum indicators turn positive

Ethereum’s share of the total crypto market capitalization held a key support zone, according to a chart shared by X user JamesEastonUK. The TradingView data showed ETH dominance stabilizing near the mid range after a sharp rebound from early 2025 lows, with price structure remaining above a long watched horizontal level.

At the same time, momentum indicators shifted. The MACD on the ETH dominance chart flipped bullish, signaling a change in trend strength after a prolonged negative phase. Meanwhile, histogram bars expanded, which reflected improving momentum rather than a flat or fading move.

In addition, volume increased alongside the recent push higher. That rise suggested broader participation as ETH dominance recovered from the lower band marked on the chart. As a result, Ethereum’s market share remained near 12.5% at the time of the snapshot, keeping the key level intact while technical signals aligned to the upside.
