Actividad de los tiburones de Ethereum y los cambios de sentimiento en los mercados de futuros de ETH

The Ethereum market in late 2025 has been defined by a tug-of-war between institutional-grade accumulation and systemic deleveraging in futures markets. As macroeconomic headwinds and a historic October crash reshaped risk appetite, Ethereum's on-chain dynamics and leveraged positioning have emerged as critical barometers of broader crypto sentiment. This analysis unpacks how whale activity and futures leverage rotations are signaling a pivotal inflection point for the second-largest cryptocurrency.

Whale Accumulation and Supply Dynamics

Ethereum's whale activity in Q3 2025 revealed a striking divergence from retail behavior. While retail investors were net sellers, large holders-defined as wallets controlling over 10,000 ETH-accumulated 934,240 ETH ($3.15 billion) over three weeks, with one notable deposit of 80,000 ETH ($226 million) to a Beacon Depositor. This move, which locks ETH into staking, not only signaled confidence in Ethereum's proof-of-stake model but also reduced circulating supply by removing assets from speculative markets. By Q4, whale accumulation continued apace, with entities like BitMine and 0x46DB adding billions in ETH despite holding at cost bases near current prices.

The shrinking ETH exchange supply ratio-now at its lowest since September 2024-has further tightened liquidity, reducing the amount of ETH available for selling. This structural shift contrasts sharply with the broader market's bearish narrative, where Ethereum's price fell 21.3% in November 2025, marking its second-worst monthly performance in three years.

Deleveraging and Market Pressure

The October 2025 crash, which erased $19 billion in leveraged positions in a single day, triggered a cascading deleveraging across Ethereum futures. Open interest in ETH futures plummeted over 50% from its $70 billion peak, outpacing Bitcoin's 38% decline. This deleveraging was driven by cascading liquidations on unified-margin platforms, where overleveraged longs were forced to close positions, resetting leverage ratios to more conservative levels.

Post-crash, Ethereum's futures market has entered a phase of normalization. Funding rates have stabilized near zero, and open interest remains 40% below October's peak. However, the ETH/BTC ratio hit a seven-month low of 0.052 in November, reflecting a shift toward lower-beta assets like Bitcoin. This divergence underscores Ethereum's struggle to attract institutional inflows amid rising U.S. yields and ETF outflows, which saw $1.4 billion exit spot ETH ETFs in November alone.

Leveraged Position Rotation as a Sentiment Barometer

Leveraged position rotation in Ethereum futures has become a critical lens for gauging macro sentiment. The October crash exposed systemic vulnerabilities in leveraged trading, particularly on centralized exchanges where margin spirals amplified liquidation pressure. In the aftermath, traders have adopted more conservative leverage, with Ethereum's Estimated Leverage Ratio on Binance dropping to 0.57-a still-elevated but normalized level compared to pre-crash highs.

Whale activity has further complicated this landscape. While some large holders have moved ETH to centralized exchanges-a bearish signal-others have doubled down on accumulation, with one whale adding 41,767 ETH in December at $3,130. This duality reflects a market in limbo: 70% of global ETH derivatives positions remain net long, yet 40% of Ethereum's supply is now held at a loss. The resulting tension between bullish accumulation and bearish repositioning has created a fragile equilibrium, with Layer-2 activity muted and price action compressed under $3,000.

Divergent Whale Strategies and Market Uncertainty

The split in whale behavior highlights Ethereum's role as both a speculative asset and a foundational infrastructure layer. On one hand, entities like Erik Voorhees have swapped ETH for Bitcoin Cash via THORChain, signaling bearishness. On the other, BitMine's accumulation of 67,886 ETH in December-valuing its holdings at $12.4 billion-demonstrates conviction in Ethereum's long-term utility.

This divergence is mirrored in futures positioning. While speculative longs have been flushed out, institutional staking and enterprise adoption of Ethereum-based solutions remain robust. Meanwhile, the Dencun upgrade looms as a potential catalyst for on-chain activity, with Total Value Secured (TVS) hitting an all-time high of 36.27 million in November.

Conclusion

Ethereum's Q4 2025 narrative is one of contradictions: aggressive whale accumulation coexists with ETF outflows, and deleveraging in futures markets contrasts with resilient DeFi TVL. Leveraged position rotation has emerged as a key indicator of macro sentiment, with the October crash resetting risk profiles and forcing traders to adopt more conservative leverage. While Ethereum's fundamentals-staking, TVS, and layer-2 adoption-remain intact, its price action continues to lag Bitcoin, reflecting broader uncertainty about its valuation as a hybrid asset.

For investors, the coming months will hinge on whether whale accumulation can offset macro headwinds and whether Ethereum's structural strengths-fee-burn mechanisms, institutional staking, and Dencun-can drive a breakout in Q1 2026. Until then, the market remains in a state of coiled tension, with leveraged positioning and whale behavior serving as the most reliable barometers of sentiment.
