The Ethereum whale is back in action! He is going long with 25x leverage, and the community believes he has identified that ETH will rise again. (Background: Don't believe Ethereum can hit $15,000 by the end of the year? An analysis of Tom Lee's predictions: It is indeed possible within three years.) (Additional context: Standard Chartered Bank reiterates that Ethereum could hit $7,500 by the end of the year: ETH buying pressure is still underestimated, and it's time to buy the dip.) The Ethereum (ETH) derivatives market is entering an unprecedented era of high leverage. On-chain data from August 2025 shows that several whale investors are accumulating long positions worth billions of dollars with leverage ratios of 15x to 25x through platforms like Hyperliquid, aiming to push ETH prices higher. Are whales betting on ETH to soar again? According to community analyst Ai Yi, the most talked-about case is a whale with a 'rolling long position of $125,000'. This account started with a principal of $125,000 and once amplified its position to $300 million; even though recent funds fell to $58,000, they added $92,000 in margin last night, opening a long position of $2,297,000 in ETH with 25x leverage, with a liquidation price of about $4,488 and a current unrealized profit of approximately $11,000. Another whale holds a 15x position of 51,000 ETH, with a nominal value of over $2.3 billion; a larger account holds 86,800 ETH, also betting with 15x leverage. Update: As ETH rebounds, the rolling position has been fully leveraged again. Currently, two addresses have opened a long position of $2,297,000 in ETH with a margin of $92,000, with liquidation prices of $4,488.02 and $4,490.8, and an unrealized profit of $11,000. pic.twitter.com/GPzVGywBqD — Ai Yi (@ai_9684xtpa) August 28, 2025 These high-leverage positions have accelerated market volatility. Recently, there was a record forced liquidation of $4.7 billion, highlighting that if prices experience a short-term pullback, the liquidation chain reaction could spread to the overall market. Institutional buying pressure is compressing circulating supply. Whales are not isolated among retail investors; in August this year, the market added 48 addresses holding more than 10,000 ETH, absorbing about $240 million in coin flow towards institutions like Galaxy Digital. Whale accounts coordinated the movement of about $1.2 billion, and within 48 hours, 200,000 ETH flowed out of centralized exchanges, mostly into staking or cold wallets, further contracting the circulating volume. Currently, whales hold about 22% of the total supply and continue to accumulate 800,000 ETH weekly, significantly reducing market float. The technical outlook is also bullish, with multiple analysis media citing bullish flag patterns, a positive MACD, and a money flow index of 83, leading the market to have high expectations for ETH to challenge $7,000. Additionally, with a net inflow of $13 billion in ETF funds in the second quarter of 2025, and the long-term effects of deflationary mechanisms, the whales' leveraged bets seem to find psychological support. However, investors must remain very cautious, as the current ETH market has gathered record bullish consensus and liquidation pressure, and the future direction will depend on whether prices can maintain a safe margin for high-leverage positions. *This article is not investment advice; please conduct careful research before making investment decisions.
