The big picture

MIAX's strong options ADV and market share gains indicate increasing adoption of its trading platform, likely driven by factors such as competitive pricing and technological advancements. However, the contrasting performance of MIAX Futures and MIAX Pearl highlights vulnerabilities within the broader exchange group. The overall trend suggests a consolidating market where specialized exchanges are gaining ground against larger, more established players.
