Ethereum Options Show Long-Term Bullish Tilt as Short-Term Put Demand Rises

Ethereum (ETH) options positioning is sending a mixed message: overall exposure continues to build in favor of upside over the medium to long term, while fresh trading activity is leaning more defensive, with traders favoring puts over the past day.

As of Thursday 01:00 UTC, data compiled by Coinglass showed total Ethereum options 'open interest' (OI) at $9.37 billion, up about 0.97% from $9.28 billion a day earlier. Calls represented 62.55% of outstanding contracts, while puts accounted for 37.45%, indicating a market still structurally tilted toward bullish exposure on a cumulative basis.

However, the flow picture looked notably different. Ethereum options trading volume over the last 24 hours totaled roughly $960 million, with puts taking 58.08% of activity versus 41.92% for calls. The split suggests that while investors are maintaining or adding longer-dated upside positions, shorter-term participants may be paying up for downside protection or volatility hedges amid heightened uncertainty.

By venue, Deribit led $305 million in notional volume, followed by Bybit at $340 million, Binance at $159 million, OKX at $146 million, and CME at $10 million. The presence of CME—though small in this snapshot—typically serves as a reference point for institutional participation, while the bulk of turnover remains concentrated on crypto-native derivatives platforms.

The largest concentrations of 'open interest' were clustered in higher-strike call contracts on Deribit, led by a $3,200 call expiring Dec. 25, 2026, followed by $2,500 and $2,000 calls expiring June 26, 2026. Such positioning is often associated with longer-horizon bullish bets or structured strategies seeking asymmetric upside exposure.

In contrast, the highest 24-hour volume was dominated by shorter-dated contracts on Bybit, led by a $1,900 put expiring March 26, 2026. The next most actively traded contracts included a $14,000 call expiring June 26, 2026, and a $2,225 call expiring March 26, 2026—an unusual mix that points to both near-term hedging demand and selective speculative interest in out-of-the-money upside.

Market participants often read a divergence between OI and volume as a clue to shifting intent: rising OI typically signals new positions being opened and a growing commitment to a directional thesis, while put-heavy volume can reflect immediate risk management needs. For Ethereum, the current setup suggests traders are simultaneously keeping longer-term upside exposure on the books while actively bracing for near-term drawdowns or volatility spikes.

In the days ahead, whether put demand persists—or fades as spot and futures stabilize—will help determine if the market’s defensive tone is a temporary hedge overlay or the early sign of a broader shift in sentiment.
