MEMX: Building an Equities Exchange from the Ground Up
As we assessed public exchanges in the U.S., we asked: How can we create an exchange today that leverages the most modern technology available? We believed a new kind of exchange could increase competition, drive operational transparency and enable lower costs for investors. We were confident we could create it.
Convening leading financial services firms, including major banks, broker-dealers and even other market makers, we led the creation of an exchange founded and run by its members. An all-electronic exchange leveraging industry-leading technology, MEMX enables its members to provide even more liquidity to the market.
In just over two years, MEMX went being from an idea on a whiteboard to the fastest growing US equities exchange. Today, MEMX is at 6.5% market share excluding TRF, with an average daily notional volume of $18.7 billion in May 2022—up from $6.7 billion in May 2021.
