Question · Q4 2025
Kenneth Worthington asked about the initial activity and market share trends for the newly launched Monday and Wednesday options, inquiring if MIAX's technology advantage was translating into market share gains. He also questioned when Tuesday and Thursday options might be introduced and what criteria MIAX would use to consider such an expansion.
Answer
Thomas Gallagher, Chairman and CEO, and Shelly Brown, CEO of MIAX Futures and Chief Strategy Officer, noted it was early days for the Monday and Wednesday options (launched January 22nd) but observed large volumes and positive industry impact. Ms. Brown highlighted MIAX's historical outperformance in these nine stocks (over 20% market share) and similar trends in the new front weeklies, attributing it to technology and risk protections. Mr. Gallagher indicated that future expansion would likely involve adding more stocks to the Monday and Wednesday program before introducing Tuesday and Thursday expirations to the existing classes, to avoid saturating the calendar and better meet investor demand.
