Ethereum (ETH) is trading around $2,578 as of Friday, down 2.6% on the day but surging approximately 46% on a monthly basis—the first positive monthly return in 2025. This notable rebound has been fueled by renewed interest from both institutional investors and large-scale holders, commonly referred to as "whales." With growing ETF inflows and significant accumulation patterns, Ethereum is regaining its spotlight in the crypto market.
Ethereum’s May Rally: Whale Buying and ETF Inflows Drive 46% Surge
According to data from Laevitas.ch, Ethereum is on track to close May with its first positive month of the year, posting a potential monthly return of nearly 46%. This shift in momentum follows easing macroeconomic pressures, particularly after the U.S. reached trade agreements with several nations including the U.K. and temporarily with China, reducing tariff-related uncertainty.
Such favorable global conditions have reignited bullish sentiment among Ethereum whales—addresses holding between 10,000 and 100,000 ETH. In May alone, these large holders increased their total holdings from 16.5 million ETH to 17.62 million ETH—an accumulation of 1.12 million ETH. This marks the largest monthly whale buying pressure since July 2022, signaling strong confidence in ETH’s long-term value.

The rise in whale activity coincides with robust demand for spot Ethereum ETFs in the United States. As of the latest reports, these ETFs have recorded **$493.94 million in net inflows** so far this month, turning their 2025 year-to-date cumulative flow into positive territory. Notably, on Thursday alone, the products attracted $91.93 million in fresh capital, marking nine consecutive days of net inflows—a strong indicator of sustained institutional interest.
Derivatives Market Shows Mixed Signals Despite Overall Bullish Trend
While spot market dynamics appear strongly bullish, derivatives data presents a more nuanced picture. Open interest (OI) across Ethereum futures markets has surged by 43%, climbing from $12.18 billion to $17.53 billion in May. Open interest reflects the total number of outstanding derivative contracts and often correlates with market participation and volatility.
However, this increase comes alongside growing bearish positioning on major exchanges like Binance, where short positions now exceed longs. This imbalance suggests that some traders may be hedging against potential downside risk—or actively betting on a correction.
Despite this, on-chain exchange flow data reveals a different story. After three days of net inflows into exchanges—typically a sign of selling pressure—Ethereum saw a reversal on Friday with over 114,000 ETH flowing out of exchanges. This net outflow indicates that investors are once again moving ETH to cold storage or personal wallets, reinforcing the idea of long-term holding behavior and reduced selling pressure in the spot market.
Technical Outlook: ETH Tests Key Support Amid Rising Uncertainty
In the past 24 hours, Ethereum experienced $117.76 million in futures liquidations**, with $98.61 million coming from long positions and $19.15 million from shorts. The spike in long liquidations followed a rejection at the critical resistance level of **$2,750, leading ETH to break below both the rising trendline of an ascending triangle pattern and the 14-day Exponential Moving Average (EMA).
This technical breakdown raises short-term concerns. If Ethereum fails to reclaim the ascending triangle’s support and closes decisively below the $2,500** level, further downside could unfold toward a key support zone between **$2,100 and $2,260. This range is reinforced by a golden cross between the 50-day Simple Moving Average (SMA) and the 100-day SMA beneath it—an indicator often associated with long-term bullish reversals when confirmed.
On the upside, regaining bullish momentum requires two key conditions:
- Sustained trading above the ascending triangle’s broken trendline.
- A confirmed breakout above $2,850, which would reassert upward trajectory and potentially trigger a new wave of buying.
Currently, momentum indicators reflect weakening bullish strength. The Relative Strength Index (RSI) and Stochastic Oscillator are both above neutral levels (50), suggesting underlying strength. However, they are declining beneath their respective moving averages, signaling diminishing upward pressure and possible consolidation ahead.

Frequently Asked Questions (FAQ)
What caused Ethereum’s price surge in May 2025?
Ethereum’s rally was primarily driven by macroeconomic improvements, including eased trade tensions and increased investor confidence. Additionally, heavy accumulation by whale addresses and strong inflows into U.S.-listed spot Ethereum ETFs contributed significantly to upward price pressure.
Are whale purchases a reliable indicator for future price growth?
Historically, large-scale ETH accumulation by whales has preceded major price rallies. These investors often have access to deeper market insights and tend to buy during periods of undervaluation, making their activity a valuable sentiment signal.
What does the ascending triangle pattern mean for ETH?
An ascending triangle typically indicates accumulation before a breakout. A break above resistance suggests continuation of an uptrend, while a breakdown below support may lead to further declines—especially if volume confirms the move.
How do ETF inflows affect Ethereum’s price?
Sustained ETF inflows reflect growing institutional adoption and increase demand for ETH in the open market. Since ETFs must back shares with actual Ethereum holdings, consistent buying supports price stability and upward momentum.
Could Ethereum retest $2,100 in the near term?
Yes—if ETH fails to hold above $2,500 and breaks down from its current range, a drop to the $2,100–$2,260 support zone is possible. However, strong whale holdings and ETF demand may limit downside severity.
Is now a good time to buy Ethereum?
Market timing is inherently risky. However, with positive macro trends, strong on-chain fundamentals, and increasing institutional participation, many analysts view current levels as favorable for long-term investment—especially given the historical significance of whale accumulation cycles.
Final Thoughts: Bullish Fundamentals Meet Short-Term Volatility
While short-term technical indicators show signs of weakness after the recent pullback, Ethereum’s fundamental landscape remains robust. Whale accumulation at multi-year highs, combined with consistent ETF inflows and improving global economic conditions, lays a solid foundation for future growth.
