First Day of Trading
MX2 Options recorded initial trading activity on its launch day, according to the company.
The exchange traded:
- More than 1,500 contracts
- 10 symbols
- 19 member firms
MEMX Group stated that the initial launch represents the starting point for a broader rollout. Following the first day of trading, the company plans to gradually expand the number of symbols available on MX2 Options over the next few weeks.
Existing Options Offering Expanded
The launch adds a customer priority, pro-rata model alongside MEMX Group’s existing price-time options exchange.
Jonathan Kellner, CEO of MEMX Group, said:
“Today’s successful launch of MX2 Options marks an important milestone for MEMX and reflects the tremendous work of our team and the support shown to us from our members and the broader options community,”
Kellner added:
“From the outset, our goal has been to build markets around the needs of participants. By adding a customer priority, pro-rata model alongside our existing price-time options exchange, we can serve an even broader range of trading strategies and provide market participants with greater choice in how they provide and access liquidity.”
The company stated that the addition gives participants greater choice in how they provide and access liquidity, while expanding the range of trading strategies that can be supported across its options offerings.
Industry Testing and Collaboration
MEMX Group stated that the MX2 Options launch followed extensive industry testing and collaboration conducted in preparation for the exchange going live.
The company said the work leading up to the launch supports its continued focus on:
- Competition in financial markets
- Flexible exchange solutions
- Innovative market functionality

The launch of MX2 Options therefore adds another exchange model to MEMX Group’s existing equity and options infrastructure.
Continued Momentum Following BOX Combination
The MX2 Options launch follows MEMX Group’s previously announced combination with BOX, a U.S. equity options market offering both electronic and floor-based trading.
MEMX Group stated that the development forms part of its continued expansion of customer functionality through strategic diversification and expansion.
