Micro Contracts Now Make Up 54% of CME Equity Index ADV

Summary
CME Group reported that Micro E-mini equity index futures and options generated 4.4 million contracts in July ADV, equal to 54% of the exchange's total Equity Index ADV. This figure makes smaller-sized products the largest reported component of CME's equity-index business. The July data gives current volume context to CME's planned E-nano launch, which will add contracts one-tenth the size of Micro E-minis. CME also reported its highest July ADV on record, with overall trading rising 23% year-on-year to 27 million contracts. Within the Nasdaq Micro Futures segment, ADV reached 8.2 million contracts, up 48% from July 2025. The strongest growth came in Micro E-mini Nasdaq-100 futures, where ADV rose 159% year-on-year to 3 million contracts. By comparison, E-mini S&P 500 futures ADV rose 24% to 1.4 million contracts, while E-mini S&P 500 options ADV increased 8% to 1.1 million contracts.
