Deribit to Delay Public Ether Options Open Interest Data by 8 Hours Starting November 5
Key Facts
Deribit will begin publishing public cryptocurrency options open interest data with an 8-hour delay on November 5, according to a support notice posted on its website. The exchange says the data will reflect open interest as it stood 8 hours before the time it is displayed. This changes the timing of the reading available to observers comparing outstanding contract volumes across consecutive sessions. While trading reports tracked open interest in Ethereum options on November 4, figures for that session could not be verified from a reliable public source in the information available. The reported figures for positions or trading activity that day therefore cannot be established as confirmed facts.
A November 3 reading from TokenPost provides a separate earlier reference point, distinct from the November 4 session. Total open interest in Ethereum options then stood at $5.44 billion, compared with $5.45 billion in the previous reading. Trading volume over 24 hours was $1.09 billion. Open interest measures contracts that remain outstanding, while trading volume measures contracts exchanged over a specified period. The two figures therefore describe different aspects of options market activity, and the November 3 reading does not correct figures for the following day.
In the same November 3 reading, call options accounted for 61.72% of open interest, compared with 38.28% for put options. By 24-hour trading volume, calls represented 60.35%, while puts accounted for 39.65%. These percentages alone do not establish whether the contracts reflect directional positions or hedging, as a high share of calls can coexist with demand for hedges. The percentages refer to the November 3 reading and do not establish the distribution of positions in the November 4 session. The measurement timing takes on added importance as Deribit begins delaying publication the following day.
The list of most-traded contracts in the November 3 reading included a Bybit call option with a $4,500 strike price expiring on November 6, 2026. It was followed by an OKX call option with a $2,350 strike price expiring on November 4, 2026, then a Binance call option with a $2,600 strike price expiring on November 6, 2026. These contracts ranked by 24-hour trading volume in the earlier reading and cannot be attributed to the November 4 session. Deribit said its market share in Bitcoin and Ethereum options is about 85%, an estimate from the exchange itself. That gives its data weight in market monitoring, while requiring attention to publication timing when making comparisons.
CME offers weekly Ether options from Monday to Friday, in addition to monthly and quarterly expiries. The exchange says weekly options allow short-term exposure to be managed throughout the week. These regulated products differ from the open interest readings published on options trading platforms, but they form part of the tools available to manage exposure and price risk. With Deribit beginning its data delay on November 5, the timing of the reported open interest reading will need to be considered when following subsequent figures. Figures for the November 4 session and its most-traded contract could not be verified against the available evidence.
