Ethereum Options Cluster at $2,500 as Short-Term Flow Targets $2,750

Ethereum (ETH) options traders are clustering around a $2,500 strike for longer-dated bullish positioning while short-dated flow is gravitating toward $2,750, signaling a split between medium-term upside expectations and near-term tactical trading.

As of April 20 at 00:00 UTC, data compiled by Coinglass showed total Ethereum options open interest (OI) at approximately $7.33 billion, down about 2.53% from $7.52 billion a day earlier. Calls accounted for 63.38% of outstanding contracts, with puts at 36.62%, indicating that the market’s standing inventory remains tilted toward 'bullish' exposure.

Notional options trading volume over the past 24 hours totaled roughly $2.33 billion. By venue, Deribit led activity with about $5.29 billion in reported volume, followed by OKX at $721 million, Bybit at $567 million, Binance at $390 million, and CME at $360 million. Despite the call-heavy OI profile, the 24-hour volume split was nearly balanced—calls at 50.68% versus puts at 49.32%—a pattern that often emerges when traders maintain upside structures while simultaneously paying for short-term protection or volatility hedges.

The largest concentrations of open interest were centered on Deribit’s longer-dated call strikes. The top contracts by OI were the $2,500 call expiring June 26, the $3,200 call expiring Dec. 25, and the $2,000 call expiring June 26. Heavy positioning at $2,500 and $2,000 suggests traders continue to frame those areas as key reference levels for the next leg of market direction, while the $3,200 strike reflects a longer-horizon bet on a more aggressive appreciation scenario.

In contrast, the most actively traded contracts over the last 24 hours were concentrated in short-dated expiries on Bybit, led by the $2,750 call expiring April 20, followed by the $2,550 call expiring April 20, and the $1,000 put expiring April 24. The dominance of same-day call flow around $2,750 points to a focus on near-term momentum and gamma-driven positioning, while the presence of deep-out-of-the-money put volume can indicate tail-risk hedging demand rather than a base-case bearish outlook.

Options are derivatives that allow traders to express leveraged views on price direction or hedge spot and futures exposure. A 'call option' gives the right to buy at a predetermined price—typically used for bullish positioning—while a 'put option' gives the right to sell and is commonly used for downside bets or protection. Open interest represents the total number of outstanding contracts and serves as a gauge of accumulated positioning; changes in OI alongside shifts in call/put participation can help distinguish between medium-term positioning and short-term defensive or volatility-driven flows.

With call-heavy open interest persisting even as short-dated volume remains mixed, the current structure suggests traders are keeping an upside bias on the books while actively managing near-term uncertainty through rapid turnover and hedging. The balance between these forces is likely to shape how ETH reacts around widely watched strikes such as $2,500 and $2,750 in the days ahead.
