The group also set a new YTD market share record at 17.1%, up from 16.5% in the prior-year period.

While equities trading showed mixed results with declines for MIAX Pearl's ADV by -33.7%, futures activity saw strong performance in agricultural contracts but faced challenges in financial futures, which launched later this year.
