Machi Big Brother's $29 Million Loss Highlights Ethereum Leverage Liquidation Wave

On February 24, 2026, a 25x leveraged long ETH position held by prominent trader Machi Big Brother on the derivatives platform Hyperliquid was forcibly liquidated, resulting in a loss of approximately $29 million. The account's remaining ETH-equivalent assets were reduced to around $24,900. This event has sparked widespread concern about deleveraging in the Ethereum derivatives market. With 25x leverage, an adverse price movement of just 4% in ETH is enough to deplete the margin and trigger liquidation. Such high-leverage positions, when liquidity is insufficient, are often accompanied by significant slippage and execution risks, exacerbating market volatility. On the day of the event, the price of ETH briefly dipped to $1,800, further triggering a dense cluster of long liquidations, creating a chain reaction.

According to market analysis, open interest in the Ethereum derivatives market has been declining since the beginning of 2026, while funding rates have been consistently negative, reflecting a waning bullish sentiment. At the same time, Ethereum ETF products have experienced outflows, weakening the market's ability to absorb liquidation sell-offs and making prices more susceptible to short-term liquidity shocks. The ETH Fear and Greed Index hovers around 35, indicating that overall market sentiment is cautious and lacks speculative fervor. Nick Ruck, Research Director at LVRG, pointed out that overcrowded long positions are often a precursor to significant liquidation events. When multiple high-leverage positions are concentrated in similar price ranges, once breached, forced liquidations can create a "stampede effect," driving prices down to the next liquidation area, significantly amplifying volatility in the short term.

The market should currently focus on three key structural signals: first, whether the trend of open interest diverges from price movements; second, whether future price approaches to historically high-leverage liquidation clusters could trigger a new round of forced liquidations; and third, while persistent negative funding rates reflect bearish dominance, they also lay the groundwork for a bullish counterattack—once market sentiment reverses, a "short squeeze" is highly likely. In addition, the flow of funds from institutions participating in the secondary market through Ethereum ETFs is increasingly becoming an important liquidity buffer. Continued ETF outflows will exacerbate the market's vulnerability to liquidations, while a stabilization of fund inflows could alleviate liquidity pressures and reduce volatility. The market structure is transitioning from speculation-driven to institution-led, and the release of leverage risk will be a key variable in the next phase of price movements.
