Cap Removed From Fee Schedule
On May 1, 2026, Cboe BZX removed language in its Fee Schedule that capped the maximum number of Dedicated Cores a market participant could purchase. The Exchange will instead note any caps in the Cboe Titanium U.S. Equities Binary Order Entry Specification; historically the Exchange had permitted up to 120 Dedicated Cores for Members and up to 35 Dedicated Cores per Sponsored Access relationship.
Potential for More Low-Latency Capacity
Dedicated Cores let a firm assign a BOE logical order entry port to a dedicated CPU core, which the Exchange says can reduce latency and improve throughput. By removing the cap text from the Fee Schedule and putting caps in the technical specification, the Exchange says it will be better able to adjust allotments based on participant requests and planned server upgrades, which could allow market participants to obtain additional Dedicated Cores and potentially boost trading speed.
No Fee Change for Dedicated Cores
The Exchange stated it does not propose to change the fee charged for Dedicated Cores as part of this filing. The Dedicated Core offering remains voluntary and available to any User that wishes to purchase it.
