Miami International Holdings Begins Publishing Bloomberg 500 Index on OPRA and MIAX Data Feeds

MIAMI and PRINCETON, N.J., April 16, 2025 /PRNewswire/ -- Miami International Holdings, Inc. (MIH), a technology-driven leader in building and operating regulated financial markets across multiple asset classes, today announced the Bloomberg^® US Large Cap Price Return Index (NYSE:B) is available through the Options Price Reporting Authority (OPRA) and MIAX Product Feed (MPF) under symbol BBX.

"The availability of BBX through the MPF and OPRA provides the industry with a valuable data source to support the new MIAX Bloomberg 500 Index Futures and Options products we plan to launch in the second half of 2025," said Thomas P. Gallagher, Chairman and Chief Executive Officer of MIH. "The industry is looking for alternative ways to manage its U.S. equity exposure and we believe our new MIAX Bloomberg 500 Index Futures and Options will offer competitive fees, enhanced product choice and more appropriate contract sizes to support the evolving needs of retail and institutional investors."

MIAX Bloomberg 500 Index Futures will be listed on MIAX Futures™, pending certain filings with the Commodity Futures Trading Commission (CFTC). MIAX Bloomberg 500 Index Options will be listed on MIAX Options, pending certain filings with and subject to approval from the Securities and Exchange Commission (SEC).

"We are thrilled that our flagship B500 Index will be more broadly available through both the MPF and OPRA," said Umesh Gajria, Global Head of Index-Linked Products at Bloomberg Index Services Limited. "The availability of BBX will allow the industry to more easily incorporate the data into trading, risk and analytical models, creating the foundation for the B500 suite of products we are building in collaboration with MIAX."

The Bloomberg^® US Large Cap Price Return Index provides a transparent, rules-based benchmark of the 500 most highly capitalized U.S. companies, resulting in a more representative benchmark for the large cap segment of the U.S. markets compared to similar indices compiled using a discretionary approach.

MIH previously announced plans to list MIAX Bloomberg 500 Index Futures and Options on its MIAX^® exchanges in the second half of 2025, subject to various regulatory filings and approvals. MIAX Bloomberg 500 Index Futures will be the first financial future to be traded on the new MIAX Futures Onyx trading platform, pending filing with the CFTC.
