Question · Q3 2025
Jeff Schmitt inquired about the drivers behind MIAX's sharp increase in October market share to 19.4% and whether there was a rise in complex trades during the month.
Answer
Shelly Brown, Chief Strategy Officer, explained that the October gains were 'across the board' for all four options exchanges. She confirmed continued growth in complex orders, noting MIAX is the second-largest exchange in this segment, and also saw growth in price improvement options, attributing these trends to the use of MIAX's technology.
