Key Takeaways
- • Deribit plans to delay public open interest data by eight hours across all futures and options, effective with its scheduled November 10, 2026 release, according to CryptoSlate.
- • The public open-interest lag applies whether or not trades were delayed, and Deribit says real-time open interest will no longer be available through its API.
- • Charts pairing current Bitcoin prices with the delayed open-interest data will mix two observation times, limiting conclusions about fresh leverage and expiry positioning.
- • Trade publication delays are narrower: qualifying large Block RFQ trades (minimum 1,000 BTC per tranche, at least 3,000 BTC overall for BTC-settled trades) may be published after eight hours, with publication scheduled by 07:00 UTC.
- • Execution, margin and equity updates remain real time, and the data lag is separate from a roughly 45-minute maintenance outage starting at 09:00 UTC.
Summary
Deribit, the crypto derivatives exchange, plans to delay public open-interest data for Bitcoin futures and options by eight hours in a release scheduled for Tuesday, November 10, 2026, according to CryptoSlate. The change means public charts of outstanding positions will show the market state as it was eight hours earlier, even as traders compare those figures with live prices. The change applies to all futures and options, whether or not any trades were delayed. The release was postponed from November 5.
The change affects analysis of leverage and expiry positioning. A chart combining current Bitcoin prices with delayed open interest mixes two observation times, so a price move alongside a rise or fall in positions cannot by itself establish whether traders added or closed positions. Concentrations of open interest across option strikes will describe earlier positioning, and "max pain" calculations that rely on the affected public data will inherit the delayed inputs. Deribit's own education material already describes max pain as a limited tool when used alone.
A separate trade-publication feature has a narrower scope. Large block request-for-quote (RFQ) trades that qualify may be published on request after eight hours. For BTC-settled Block RFQs, the minimum is 1,000 BTC per tranche, with an overall requested trade of at least 3,000 BTC within one settlement cycle. On-screen trades, liquidations and blocks outside Block RFQ are excluded. Qualifying trades will normally be published after eight hours, though the wait shortens so publication is scheduled by 07:00 UTC, one hour before daily settlement at 08:00 UTC. Trades executed in the final hour before settlement will be published immediately. Delayed trades enter 24-hour volume eight hours after execution and remain included for the following 24 hours; other trades count in real time.
Deribit says execution remains immediate and margin and equity updates remain real time. The public data lag affects visibility only, while trading and risk calculations continue on their own clocks. The data change is separate from a scheduled maintenance window at 09:00 UTC, which includes about 45 minutes of downtime during which clients cannot communicate with the exchange.
