Cboe Tweaks Auction Fees: Traders, Check Your Wallets

## Summary

Cboe C2 Exchange is updating its fee schedule to set clear rules for charges during Step Up Mechanism (SUM) auctions. This change affects traders using SUM auctions by adjusting how fees are applied to different order types. The new fees take effect immediately, so traders should check the updated schedule to understand any cost impacts.

## Effects PRIA read

- SUM auctions: who pays add vs remove: mixed, medium. For executions inside Step Up Mechanism (SUM) auctions, the incoming (primary) order will receive the applicable Remove rate, and auction responses and unrelated orders will receive the applicable Add rate. This new fee assignment language was filed on September 11, 2026 and is effective immediatel…
- No new fees or fee amounts changed: benefit, low. The Exchange states the proposal does not adopt any new fee and does not change the amount of any fee currently assessed under the Fee Schedule; it only changes how existing add/remove fees are applied to SUM auction volume. This language was included in the filing submitted September 11, 2026.
- DJX and RUT excluded from SUM treatment: benefit, low. The SUM auction remove/add fee treatment does not apply to orders in DJX and RUT because those products have their own pricing tables in the C2 Fee Schedule. This explicit exclusion was included in the Exchange's filing that became effective upon filing on September 11, 2026.
