Monthly Fee Hike for Legacy Silexx
Starting June 2, 2025, Cboe is raising monthly fees per Login ID for certain Legacy Silexx platforms: Basic rises from $625 to $938, Pro rises from $625 to $938, and Buy‑Side Manager rises from $475 to $715. These higher monthly charges apply to users who continue using those Legacy Platform versions.
Pro Plus Risk Fee Remains Unchanged
Effective June 2, 2025, the monthly fee for the Pro Plus Risk Legacy Platform will remain $950 and will not be increased at this time. The Exchange states this change is to mitigate costs for Pro Plus Risk users who cannot yet disable certain logins.
Legacy Platforms Planned Future Decommissioning
The Exchange states it plans to decommission the Legacy Platforms at a future, to‑be‑determined date, at which time those Legacy Platforms will be unavailable to users. The filing reiterates that use of the platform is voluntary until decommissioning occurs.
Newer Silexx Versions Not Affected
The fee changes apply only to Legacy Silexx platform versions; users of newer versions (Cboe Silexx and Silexx FLEX) are not affected by the June 2, 2025 fee changes. The Exchange is actively transitioning users from Legacy Platforms to the newer versions.
