Published Date: 10/9/2026

Notice

Summary

MEMX is updating its options trading fees starting October 1, 2026. They’re renaming a volume discount tier and tweaking which trades count for discounts. This change mainly affects traders using MEMX’s options platform and could impact how much they pay in fees.

Analyzed Economic Effects

2 provisions identified: 1 benefits, 1 costs, 0 mixed.

Customer-to-Customer Trades Lose Enhanced Rebate

Starting October 1, 2026, MEMX will limit its enhanced Volume Tier rebate so that only Customer-capacity executions that add liquidity in Penny options with a Non-Customer contra-party are eligible for the enhanced $0.53 per-contract rebate. Customer-to-Customer executions will not be eligible for the $0.53 enhanced rebate and instead will receive the base rebate of $0.49 per contract even if the Member meets the ADAV criteria.

Volume Qualification Rules Remain Unchanged

MEMX keeps the Volume Tier ADAV qualification the same: a Member must achieve an ADAV equal to or greater than 1.2% of the equity and ETF option total consolidated volume (TCV) in a month to be eligible for the enhanced rebate. All of a Member's Added Customer Penny Volume and Added Customer Non-Penny Volume, regardless of contra-party, will continue to count toward the monthly ADAV calculation.
