CME Group is offering a Pilot Program for clients who achieve specific technical milestones in the Sandbox-Dallas environment. The first 50 participants to complete each obligation by the deadline and submit proof will earn a stipend. Details on this program are available in the CME Globex Sandbox-Dallas Pilot Program Agreement.

Information on compute pricing for U4C Bare Metal and U4S Virtual Machine instances is available now from Google Cloud’s Account Teams.

Events and Announcements

CME Globex Connectivity Upgrades and Changes for Listed Derivative Markets - June 27

In response to client feedback and to provide firms with additional time to prepare, CME Group extended the deadline for the previously announced network equipment upgrades.

Starting Saturday, June 27, CME Group plans to replace End-of-Life network equipment that supports listed derivatives connectivity at CME Globex Hubs. Customers will be notified in advance if they are impacted by an equipment upgrade.

CME Globex market data for listed derivatives now regularly exceeds 1Gbps, increasing the risk of packet loss, performance concerns, and quality of service degradations on 1Gbps connections.

Impact on 1Gbps Listed Derivatives Connections

• Multicast Market Data: Effective June 27, 1Gbps services will no longer support MDP 3.0 multicast market data.
• Existing 1Gbps Customers with Market Data: Customers with 1Gbps service currently listening to multicast market data are encouraged to upgrade connections to 10Gbps as soon as possible.
• Existing 1Gbps Customers without Market Data: Unicast services such as iLink, Drop Copy, STP, MQ and others will continue to be supported on 1Gbps connections. Customers with 1Gbps connectivity who are not receiving Market Data will have their service migrated to the new equipment.
• New 1Gbps Connections: New connections for 1Gbps service do not support access to listed derivatives multicast market data.

Copper Handoffs

• When the CME Globex Connectivity upgrades are rolled out in 2026, CME Group will no longer support copper handoffs.

Additional details about the CME Globex Connectivity upgrades will be announced in future CME Globex Notices.

Please contact your Global Account Manager for additional information.
