Miami International Holdings, Inc. (MIH), a technology-driven leader in building and operating regulated financial markets across multiple asset classes, announced the successful launch of MIAX Futures™ Onyx, a proprietary technology platform designed to power trading of agricultural and financial futures, and options on futures in geographically diverse locations.

"Developed by our world-class technology team with the same proven systems that power our MIAX^® exchanges, we believe that the MIAX Futures Onyx technology platform sets a new standard for fast, reliable trading technology for the futures industry," said Thomas P. Gallagher, Chairman and Chief Executive Officer of MIH. "We remain committed to supporting the agricultural industry and look forward to continued collaboration with our valued Minneapolis HRSW market participants who have trusted MIAX Futures (formerly Minneapolis Grain Exchange), for over a century." 

The launch of MIAX Futures Onyx aligns with MIH's strategy of building and operating all its markets on MIAX proprietary technology and is expected to significantly expand the range of products and clearing services offered to MIAX Futures customers. Bloomberg 500 Index Futures will be traded on the platform once launched in the second half of 2025, pending filing with the Commodity Futures Trading Commission (CFTC).

Additionally, this launch marks the migration of MIAX Futures' Minneapolis Hard Red Spring Wheat (Minneapolis HRSW) Futures trading onto the new, in-house platform and completes the post-acquisition modernization of the entire MIAX Futures trading and clearing infrastructure.
