The Chicago-based exchange saw broad-based growth across its asset classes, with equity index products leading the momentum. ADV in that sector climbed 54% to 10.1 million contracts, bolstered by heavy trading in Micro E-mini Nasdaq-100 and S&P 500 futures. Agricultural products also reached a new high, hitting 2.3 million contracts as demand for corn and wheat futures intensified.

Interest rate products remained a cornerstone of the exchange's performance, rising 17% to 13.6 million contracts. Within this segment, U.S. Treasury futures and options saw sustained interest, particularly in the 10-year and 2-year notes. Simultaneously, the cryptocurrency segment experienced a sharp 76% jump in ADV to 334,000 contracts, representing a notional value of $10.7 billion.

International participation played a significant role in the monthly figures, with ADV outside the U.S. rising 17%. The BrokerTec platform saw its average daily notional value climb 17% to $1.078 trillion, reflecting robust liquidity in the U.S. and European repo markets. These results follow a strong second quarter, which saw overall ADV reach 29.8 million contracts.
