MEMX options operations updates

Highlights

MEMX will enable user portal configuration for MEMOIR options data channels June 26, with production data available across all channels starting June 29.
MEMX will eliminate Volume Tier 1 and implement new MEMX Options transaction fees on June 1, impacting trading cost structures for participants.
MEMX announced MX2 Options will launch September 14, 2026, requiring brokers, market makers, and data subscribers to update technical and trading operations accordingly.

Options platform changes and implementation dates

As reported by MEMX, the exchange is resuming the expansion of data across additional MEMOIR channels for MEMX Options and is encouraging subscribers to maintain separate circuits for top and depth feeds.

Clients can configure MEMOIR channels across multiple connections through the user portal, while those that prefer a single connection can continue to receive all MEMOIR channels that way. The implementation timetable lists June 26 for user portal configuration availability, June 27 for verification of the new channels, and June 29 for production symbol market data across all MEMOIR channels.

MEMX also says MX2 Options pre-production is now available. Separately, the exchange has announced a September 14, 2026 launch date for MX2 Options, alongside additional milestone dates and related operational information.

Earlier in June, MEMX said it would roll back production depth and top data feeds to eight channels on June 8, with the additional MEMOIR channels providing heartbeat messages only. The exchange also says changes to MEMX Options transaction fees take effect June 1, including the elimination of Volume Tier 1.

Trading calendar and market participant impact

For market participants, the notices provide a concentrated schedule of operational deadlines that affect connectivity planning, testing and trading cost assumptions across the U.S. options market.

MEMX says MEMX Equities and MEMX Options are closed on Friday, July 3, 2026 in observance of Independence Day, with normal trading resuming on Monday, July 6, 2026. The exchange also notes that both markets are closed on Friday, June 19, 2026 for Juneteenth National Independence Day, with normal trading resuming on Monday, June 22, 2026.

The combination of channel configuration changes, pre-production availability and fee updates means brokers, market makers and data subscribers need to align technical and trading preparations with MEMX's published 2026 timetable. For firms using MEMX market data and options connectivity, the sequence of alerts points to continued infrastructure adjustments ahead of the MX2 Options rollout.

We also noted that Alphabet’s addition can influence investor attention and trading flows among funds and traders that track the Dow, underscoring how structural market changes can ripple through participation and execution.
