MIAX CEO Named Chief Executive of the Year

Before joining full-time, he was a founding partner of the corporate and securities law firm Gallagher, Briody & Butler. - Under Gallagher's leadership, MIAX has pursued an aggressive expansion strategy through acquisitions, including the Bermuda Stock Exchange (BSX), the Minneapolis Grain Exchange (MGEX), Dorman Trading, and The International Stock Exchange (TISE). - This growth strategy has resulted in significant market share gains; the MIAX Exchange Group's annual market share for options reached a record 17.1% in 2025, a 13.1% increase year-over-year. The group also hit a record average daily volume of 9.5 million contracts in 2025, a 42.2% increase from the previous year. - Technologically, the company launched MIAX Futures Onyx in June 2025, a proprietary platform for trading agricultural and financial futures. This platform is built on the same systems that power its options exchanges. - In 2025, Gallagher also led the company through its initial public offering and a secondary offering. - A key strategic move involved the sale of a 90% stake in the MIAX Derivatives Exchange (MIAXdx) to a joint venture established by Robinhood and Susquehanna International Group in January 2026. Gallagher stated the sale reaffirms MIAX's strategy of partnering with industry leaders to accelerate growth.
