PANews reported on November 26th, citing Bloomberg, that Robinhood and hedge fund Susquehanna International Group are taking over a regulated exchange previously linked to the now-bankrupt crypto firm FTX, giving the two companies a new foothold in the prediction market space. The two companies are acquiring a majority stake in MIAXdx (formerly LedgerX), a U.S.-based derivatives exchange formerly owned by FTX and now operated by Miami International Holdings (MIH). Financial details of the deal were not disclosed, but MIH stated it will sell 90% of the exchange to the group led by Robinhood. Robinhood stated it will become the "controlling partner" in the new joint venture, while Susquehanna will act as the "first-day liquidity provider" to ensure clients have counterparties for their trades.

Both acquiring companies already have close ties to prediction markets. Susquehanna has stated that it is a market maker for the prediction market Kalshi. Robinhood provides Kalshi event contracts to its retail investment clients. This new deal will give Robinhood and Susquehanna direct control over the infrastructure needed to list and clear event contracts on their own terms.
