In the end of 2016, they plan to release two products:
- CME CF Bitcoin Reference Rate (BRR) - for daily settlement price at 4pm London
- CME CF Bitcoin Real Time Index (RTI) - for realtime prices, updated every second.
From the CME announcement:
The BRR will aggregate the trade flow of major bitcoin spot exchanges during a specific calculation window into a once-a-day, transparent reference rate of the U.S. dollar price of bitcoin.
The RTI will be calculated by Crypto Facilities and will be based on global demand to buy and sell bitcoin aggregated into a consolidated order book. It will reflect the current market price of bitcoin in U.S. dollar terms and will be published approximately once every second.
