Cboe BZX Sets Price on Synchronized Trading Time

## Summary

Cboe BZX Exchange just rolled out a new Clock Service that helps users sync their time systems with the Exchange’s for better accuracy. Starting May 18, 2026, they’re charging fees for this service but offering a free trial to get everyone started. This affects both members and non-members who want precise timing for their trading activities.

## Effects PRIA read

- Clock Service Fees Adopted: cost, medium. Cboe BZX adopted paid access for its new Clock Service effective May 18, 2026. The service is optional, available to Members and non‑Members, and subscribers may cancel at any time.
- Monthly Clock Service Charge $7,500: cost, high. If you subscribe to Cboe Clock Service, the Exchange charges $7,500 per month for the Clock Service itself. That monthly fee includes a single 1 Gbps physical port and permits access for all eight Cboe exchanges.
- Optional Redundant Connection $2,500/month: cost, medium. Cboe offers an optional redundant Clock Service connection for $2,500 per month per 1 Gbps physical port; firms may purchase multiple secondary connections. Monthly fees (including additional connections) are prorated for mid-month starts; the proration does not apply to one-time setup fees.
- One-Time HATI License Fee $5,000: cost, high. Firms that do not use a Safran White Rabbit-enabled switch must pay a one-time High-Accuracy Timing IP Core (HATI) set-up fee of $5,000 per physical connection to enable the Clock Service. If a subscriber needs licensing for two connections, the firm would pay $10,000 total as a one-time cost.
- 30-Day Free Trial for New Subscribers: benefit, medium. Cboe provides a 30-day free trial for first-time Clock Service subscribers; the trial applies only to the Clock Service monthly fee. Trial participants remain liable for any one-time HATI setup fee per connection and for any additional connections purchased during the trial.
