Ethereum (ETH) options positioning eased slightly over the past day, with total open interest slipping to $6.61 billion even as traders concentrated fresh activity in near-dated upside bets—most notably a $2,400 call that led 24-hour turnover. The mix suggests a market that remains broadly constructive on ETH, while tactically trading short-term moves and volatility around key price levels.
As of May 18, 1:00 a.m. ET, data compiled by Coinglass showed ETH options open interest (OI) at $6.61 billion, down about 2.22% from $6.76 billion a day earlier. Calls accounted for 60.13% of outstanding contracts, while puts made up 39.87%, indicating a continued tilt toward bullish exposures on a positioning basis.
Total ETH options trading volume over the past 24 hours came in at roughly $699 million. By venue, activity was led by Bybit at $346 million, followed by Binance at $146 million, Deribit at $127 million, OKX at $77 million, and CME at $3 million. In flow terms, calls represented 58.14% of 24-hour volume versus 41.86% for puts—broadly consistent with the open-interest skew, though the put share remains sizable enough to signal ongoing hedging demand.
The largest concentrations of open interest were clustered around three contracts: a $2,100 put expiring May 29 on Deribit, a $3,200 call expiring Dec. 25 on Deribit, and a $2,500 call expiring June 26 on Deribit. The lineup highlights two competing focal points for traders: downside protection around the low-$2,000s and longer-dated upside participation into year-end.
Short-dated activity, however, was more decisively tilted toward calls. The most actively traded contracts over the past 24 hours were a $2,400 call expiring May 18 on Bybit, a $2,450 call expiring May 19 on Bybit, and a $2,250 call expiring May 18 on Bybit. The dominance of near-expiry strikes points to traders using options to express fast-moving directional views or to position for heightened intraday swings rather than building longer-horizon exposure.
For market participants, the interplay between 'open interest' and daily volume is often as important as the headline totals. Falling OI alongside heavy trading can indicate positions being actively rolled or closed, while a persistent call-heavy OI base paired with meaningful put activity may reflect a blend of bullish positioning and protective hedges. In practice, options are widely used to take leveraged views on price direction or to hedge spot and perpetual futures exposure; calls confer the right to buy at a set price, while puts confer the right to sell.
With ETH options OI still elevated in absolute terms and activity concentrated at nearby call strikes, traders appear to be watching the $2,250–$2,450 zone as a key short-term battlefield—while keeping one eye on downside insurance around $2,100 and a longer-term bullish target near $3,200. The distribution underscores a market balancing 'risk-on' interest with ongoing demand for protection, a common pattern when volatility expectations remain fluid.

💡 Strategic Points
{"1":"Track OI vs volume together: falling OI with heavy volume can imply closing/rolling rather than fresh risk being added.","2":"Short-dated call dominance (e.g., $2,400/$2,450, near expiry) suggests traders are targeting immediate moves; expect sensitivity to spot swings and volatility shifts around these strikes.","3":"The $2,250–$2,450 zone acts as a near-term ‘gamma’/positioning battleground—breaks above/below may accelerate hedging flows.","4":"Large $2,100 put OI indicates a commonly chosen hedge level; if ETH approaches it, demand for protection or put monetization could increase and impact implied volatility.","5":"Year-end $3,200 call OI shows longer-horizon bullish participation persists; rallies may face partial profit-taking/hedge adjustments into that strike over time.","6":"Put share remains sizable (~40% OI; ~42% volume): market posture is ‘constructive but cautious’—bullish exposure paired with protection is typical when volatility expectations are unstable."}

{"open_interest":"Total number of outstanding (not yet closed) option contracts. Rising OI often means new positions are being added; falling OI can mean positions are being closed or rolled.","options_volume":"Contracts traded over a period (here 24h). High volume with flat/down OI can indicate churn/rolls rather than net new exposure.","call_option":"Gives the buyer the right (not obligation) to buy the underlying at a specified strike price by/at expiry; typically used for upside exposure.","put_option":"Gives the buyer the right (not obligation) to sell at the strike price by/at expiry; typically used for downside protection or bearish views.","strike_price":"The pre-set price at which the option can be exercised (e.g., $2,400 call).",
