On 30th July 2026, Members Exchange (MEMX) announced a definitive agreement for TMX Group (TSX:X) to make a strategic investment in MEMX. Concurrent with that transaction, BOX, a US equity options market with both electronic and floor-based trading, will be combined with MEMX, and TMX Group will have an approximately 59% ownership interest in the combined business.
The proposed combination will significantly enhance MEMX’s capabilities and scale by bringing together two leaders in the US listed options market while providing liquidity for MEMX’s existing equity holders through the investment by TMX Group.
Strategic combination features funding of approximately US$800 million in cash (plus contribution of BOX stake) from majority owner TMX Group, supported by key MEMX and BOX participants rolling equity into the new combined group.
The expanded US multi-asset class operator will hold three exchange licenses and represents approximately 10% of the US listed options volume.
The newly combined company will hold three exchange medallions and operate three US listed options exchanges, an equities exchange, as well as a technology business providing market technology and operational support to other market centres. The combined business will continue to operate independently after the transaction is completed.
