In a statement released Tuesday, Robinhood said the joint venture — controlled by Robinhood Markets Inc. — will acquire MIAXdx, a Derivatives Clearing Organization and Swap Execution Facility operated by Miami International Holdings. MIAXdx is already a designated contract market regulated by the U.S. Commodity Futures Trading Commission (CFTC).

As part of the agreement, MIAX will retain a 10% equity stake in the new exchange. Susquehanna will serve as a day-one liquidity provider, with more partners expected to join before launch. The upcoming exchange is scheduled to begin operations in 2026, offering a suite of futures, derivatives, and prediction-market contracts.

“Robinhood is seeing strong customer demand for prediction markets, and we’re excited to build on that momentum,” said JB Mackenzie, VP and general manager of futures and international at Robinhood. “Our investment in infrastructure will position us to deliver an even better experience and more innovative products for customers.”

Robinhood emphasized that prediction markets have become the company’s fastest-growing product line by revenue, with more than 9 billion contracts traded by over 1 million customers so far.

The company has steadily expanded in the space throughout 2025. In March, it partnered with Kalshi to introduce a prediction-markets hub covering U.S. politics, macroeconomic indicators, and sports. By August, new sports-related markets tied to the NFL and NCAA football had also gone live.

The new exchange marks a strategic shift as Robinhood and its partners prepare to compete in a regulated prediction-market landscape, aiming to capture rising demand for event-driven financial products in the United States.
