CME Group Expands Smaller Contract Offerings with Launch of E-nano Equity Index Futures

CME Group has launched E-nano equity index futures, which track four major US benchmarks and are one-tenth the size of its Micro E-mini contracts. The new contracts trade 23 hours a day and can be offset against positions in corresponding Micro E-mini and E-mini futures.

The E-nano contracts have multipliers ranging from $0.05 to $0.50 per index point, depending on the underlying benchmark. CME said it introduced these products to increase market accessibility and provide another way for participants to manage exposure to the four benchmarks.

This move comes as some of CME's existing micro contracts are recording higher volumes. Micro E-mini equity index futures averaged 4.4 million contracts per day in July, representing 54% of CME's overall equity index average daily volume. The Nasdaq-100 contract recorded particularly strong growth, with Micro E-mini Nasdaq-100 futures ADV reaching 3 million contracts, up 159% from July 2025.

Smaller versions of established derivatives are not limited to CME. Other exchanges, such as Cboe Global Markets, also list similar products, including Mini-SPX options and Mini VIX futures. The exchange has proposed a 10-Barrel WTI crude oil future at one-tenth the size of its existing Micro WTI contract.
