Miami International Holdings (NYSE:MIAX) reported record-breaking trading results for March 2026, as the exchange operator continues to capture a larger slice of the U.S. options and equities markets through the first quarter of the year.
The company, which operates the MIAX Exchange Group, saw its year-to-date (YTD) average daily volume (ADV) surge to 10.9 million contracts, representing a 26.6% increase compared to the same period in 2025.
This volume spike was accompanied by a record YTD market share of 17.3% through March, signaling a successful expansion of the firm’s competitive footprint against rival exchange operators.
The March performance highlights a sustained period of high volatility and retail participation in the derivatives markets.
MIAX’s growth was distributed across its multi-list options, U.S. equities, and proprietary MIAX Futures platforms.
While specific revenue figures were not disclosed in the preliminary volume report, the company directed investors to its rolling three-month revenue-per-contract and capture rate data available on its corporate website.
