Miami International Holdings, Inc. (MIH), the parent holding company of the MIAX Options Exchange (MIAX Options), and Ledger Holdings Inc. (Ledger Holdings), the parent holding company of LedgerX LLC (LedgerX), today jointly announced that MIH has completed an investment in Ledger Holdings. MIH was also instrumental in assembling a consortium of other investors who have co-invested with MIH in Ledger Holdings.

LedgerX will promptly seek approval from the U.S. Commodity Futures Trading Commission (CFTC) to be registered as a derivatives clearing organization (DCO) and a swap execution facility (SEF) for options based on digital currency. LedgerX’s initial plan is to list and clear fully collateralized, physically settled options on bitcoin and other forms of digital currency. If approved by the CFTC, LedgerX would be the first federally regulated DCO and SEF permitted to offer both a trading facility and clearing services for options based on digital currency for the institutional market.

In connection with MIH’s investment, the parties also entered into an agreement whereby MIH received a 10-year, exclusive worldwide right to license equity or fixed income products related to digital currencies that are developed by LedgerX and to develop its own equity or fixed income derivatives products based on such LedgerX products to be listed on MIAX Options and MIAX PEARL, MIH’s second options exchange. MIH also secured similar rights for securities to be listed on its MIAX Equities Exchange, once launched. Additionally, MIH’s technology subsidiary, MIAX Technologies, and LedgerX will pursue technology support and services opportunities per the terms of their agreement.

“MIH is pleased to be partnering with Ledger Holdings as it seeks approval from the CFTC for LedgerX to become the first U.S.-regulated combined digital currency derivatives exchange and clearing house,” said Thomas P. Gallagher, Chairman and Chief Executive Officer of MIH. “We are also excited to bring digital currency-based derivatives products to market that will be exclusive to MIAX Options and MIAX PEARL and to pursue other ventures pursuant to the parties’ licensing agreement. Products will initially cover an index centered around the underlying price of bitcoin, a broad-based index on several digital currencies, and a volatilitytype index.”

“MIH’s investment provides us the capital that is critical to help us meet minimum financial requirements necessary to be approved as a DCO and SEF by the CFTC, and we are thrilled to call MIH one of our key investors,” said Paul Chou, President and Chief Executive Officer of Ledger Holdings. “This investment not only shows MIH’s confidence in our future growth, but it also gives us access to a seasoned management team in the derivatives exchange space as we prepare to launch LedgerX. We look forward to a mutually beneficial relationship with MIH for years to come.”

Continued Gallagher, “To be involved with a company at the forefront of a new exchange space such as digital currency and to also have secured exclusive product licensing and development rights for the underlying security is a tremendous opportunity, and one we believe will result in a huge competitive advantage for MIAX Options and MIAX PEARL.”

John Smollen, Executive Vice President – Head of Exchange Traded Products and Strategic Relations at MIH, who was involved in the transaction, also commented, “We have no doubt that LedgerX will establish itself as a preeminent exchange and clearing house for digital currency with the management team that Ledger Holdings has assembled.”
