The exchange operator, which manages MIAX, MIAX Pearl, MIAX Emerald, and MIAX Sapphire, also captured a 16.9% market share in U.S. multi-list options through June. This figure edges out the 16.4% market share recorded during the first half of the previous year. In June alone, the group handled an average daily volume of 11.3 million contracts, reflecting a 37.7% uptick from the prior-year period.

While the options segment saw steady gains, the company's performance in other areas remained mixed. MIAX Pearl’s equities trading saw a slight decline in market share to 0.9% for the year-to-date period, down from 1.1% in 2025. Meanwhile, the MIAX Futures Exchange experienced fluctuations, with agricultural futures volume trailing behind 2025 levels, even as the exchange continues to integrate its newer financial futures offerings launched in May.
