Miami International Holdings (NYSE:MIAX) reported a significant spike in trading activity for February 2026, as the exchange operator’s aggressive expansion into short-dated options and new trading venues continues to capture a larger slice of the U.S. derivatives market.
The Princeton and Miami-based company announced that Average Daily Volume (ADV) for the MIAX Exchange Group—which includes MIAX, MIAX Pearl, MIAX Emerald, and the recently launched MIAX Sapphire—reached 10.8 million contracts in February.
This represents a 25.4% increase compared to the same month last year.
The group’s total market share for multi-listed options rose to 17.1%, up from 15.8% in February 2025.
The momentum in options was complemented by a sharp monthly recovery in the company's futures division.
MIAX Futures reported an ADV of 14,944 contracts, a 103.1% jump from January 2026 levels.
While the figure remains 38.5% lower than the year-ago period, the sequential doubling of volume suggests a stabilization following the company’s recent strategic pivot, which included the sale of a 90% stake in its MIAXdx prediction market to a Robinhood-led venture.
