4. Which cryptocurrencies are covered by the cryptocurrency futures data provider? As of June 2025, the CME trades Bitcoin, Ether, Solana and XRP futures contracts.
5. Are the futures indices calculated on a real-time basis? S&P DJI performs intraday index calculations using the CME’s real-time exchange-traded futures prices every five seconds. At each fixed interval, the index is computed with the latest real-time pricing for each underlying constituent included in the index. If a new price is not available since the last real-time calculation, the calculation will use the last available traded price provided by the exchange. Please refer to the Real-time Index Calculation section of the S&P Commodities Indices Policies and Practices Methodology for more information.
6. What pricing is used as end of day for futures index calculation? S&P DJI uses the CME’s provided settlement prices for official end-of-day index calculations. Please refer to the End-of Day-Calculations (EOD) section of the S&P Commodities Indices Policies and Practices Methodology.
7. When are the S&P Cryptocurrency Indices calculated? In addition to real-time calculations, the indices are calculated at end of day five days a week (Monday through Friday) in U.S. dollars. End-of-day pricing is typically reported by 6:00 p.m. EST. Index files are published after that time following S&P DJI’s standard file delivery format.
8. Which cryptocurrencies are included in the futures indices? The S&P Cryptocurrency Futures Indices include Bitcoin, Ethereum, Solana and XRP.
The Commodities and Options Index Committee (COPTIC) reserves the right in its sole discretion to cease or suspend publication of an index or remove an index component that becomes subject to a legal, regulatory, or practical concern (e.g., because the digital asset underlying the futures contract may be an unregistered security, allegations of trading manipulation, potential implications of U.S. or other economic sanctions, inclusion of digital asset privacy features that may pose anti-money laundering concerns, assets being subject to a hacking event, etc.) or due to potential market disruption. If there is a market disruption, or a disruption with the data provider, the indices are calculated based on the last available price. The non-futures based indices, S&P Cryptocurrency Indices based on Lukka data, are governed by the S&P Digital Assets Index Committee.
9. How often do the indices rebalance? How does the rebalance process work? CME Bitcoin, Ether, Solana and XRP futures contracts roll monthly. S&P DJI publishes daily and monthly rebalanced S&P Cryptocurrency Futures Indices.
The daily rebalanced index rebalances (or rolls) on a daily basis between the front contract into the next month futures contracts using an equal percent each day. On t-2 market close—that is, two business days before the expiry of the front contract—the index will be entirely in next month’s contract.
The monthly rebalanced indices use a five-day rebalance (or roll) between the front contract into the next month futures contracts, from t-6 to t-2—that is, from six business days through two business days before expiry of the front contract. On t-2 market close—that is, two business days before the expiry of the front contract—the index will be entirely in next month’s contract.
10. How is the S&P Cryptocurrency MegaCap Futures Index weighted? How often is the weighting adjusted? The index is market capitalization weighted, using the allocation of coin supply of the S&P Cryptocurrency MegaCap Index as of the last rebalance date. Using the coin supply value is intended to add stability because exposure will not change when the futures price of the cryptocurrency changes relative to the price of underlying cryptocurrency. Coin supply is the total number of coins mined (or issued) for a given cryptocurrency since inception. See the S&P Digital Assets Index Mathematics Policies and Practices Methodology for details. The weighting of the indices is adjusted on a quarterly basis.
11. Can cryptocurrency futures prices deviate from spot prices? While futures prices can deviate from spot prices, futures can also add price discovery and price transparency to an emerging market.
12. How do the S&P Cryptocurrency Futures Indices address price spikes or price outliers? What happens if the futures price is significantly different from futures prices at other futures exchanges? S&P DJI uses pricing from third-party sources for all its indices. Price checks take place at the pricing provider, CME. CME futures trade exclusively on the CME exchange, a regulated market. See question 6 for additional details.
There are other exchanges that trade Bitcoin, Ethereum, Solana and XRP futures and it is possible that their futures prices may be different from CME’s futures pricing.
13. What types of reference data fields are provided to S&P Cryptocurrency Futures Index subscribers? Subscribers of the S&P Cryptocurrency Futures Indices end-of-day index data packages receive the roll weights, contracts, and settlement prices.
14. How much history is available for these indices? Back-tested index history for these indices varies based on the constituents, with the earliest inception date being in December 2017.
