7 Day iLink CGW Sessions - This Week

Effective this Sunday, May 10 (trade date Monday, May 11), new 7 day (7D) sessions will be required for all iLink and Drop Copy Convenience Gateway (CGW) users to participate in CME Globex 24/7 weekend trading. These 7D CGW sessions can be used to trade all 5 day and 7 day products moving forward.

iLink CGW users must create new 7D CGW sessions, which are now available in the Request Center (ESS), but will not be available for trading until this Sunday, May 10.

Drop Copy CGW users must update their configuration to include a new dedicated target session, which will be auto-created by the Drop Copy service to support 7D CGW sessions.

Existing 5 day (5D) CGW sessions may be used to trade 7 day products from Sunday at 5:00 p.m. Central Time (CT) through Friday at 4:00 p.m. CT, but will be restricted from extended weekend trading hours.

To facilitate the transition, CME Group will waive Port Activation Charges (PAC) for all 7D sessions through July 2026. Monthly Inactivity Charges (MIC) remain in effect; a minimum of 100 traded contracts per month is required to avoid the $100 service charge.

Please Note: 7D sessions will not be available for weekend testing (mock trading sessions). Firms interested in weekend testing should retain a small number of 5D CGW sessions for this purpose. CME Group will waive the MIC for up to five 5D CGW sessions, maintained specifically for testing, per CME Globex Firm ID (GFID).

iLink and Drop Copy Market Segment Gateway (MSGW) sessions are unaffected and can access all 24/7 products, provided the associated GFID is enabled by the responsible FCM.

Please contact Global Account Management with any questions.

iLink and Drop Copy CGW Support for Swap-Based Event Contracts - This Week

Starting at 4 p.m. Central Time on this Sunday, May 10, swap-based event contracts will support iLink and Drop Copy Convenience Gateway (CGW) sessions.

Globex Credit Controls (GC2) - Exposure Limits Update - May 11

Effective Monday, May 11, CME Group will implement distinct weekend and weekday exposure limits within Globex Credit Controls (GC2) in Risk Management Tools (RMT).

Clients authorized to trade products with weekend trading enabled are required to update their GC2 weekend exposure limits by 16:00 CT on Friday, May 15.

If limits are not updated, this will result in the disabling of weekend trading capability, as the default limit is set to zero (0).

Firms are reminded that, pursuant to Rule 916, a Base Clearing Member must be approved to clear transactions for Base products (e.g., futures and options) that clear on the next business day during Supplemental Trading Hours (e.g., certain hours during the weekends), as defined in Rule 916. For more information, please refer to this Clearing House Advisory.

Details on setting exposure limits are available in the Globex Credit Controls (GC2) - User Manual.

User-Defined Spreads Lifecycle Modification - May 24

To accommodate the extension of 24/7 trading schedules to futures and options markets, effective Sunday, May 24, the lifecycles for all User-Defined Spreads (UDS) on CME Globex will be modified as follows:

• All UDS on CME Globex following the Weekly with Extension and Daily with Extension lifecycles will be created with a Last Trade Datetime (LTD) of Saturday at 2:00 a.m. Central time (CT).

  • Currently, these UDS use the close on the nearest Friday as the LTD.

• All expiring UDS on CME Globex will be removed on Saturday during the Extended Maintenance Window on Saturdays at 2:00 a.m. CT.

  • Currently these spreads are removed after the close on Friday night.

With this change, clients will be able to trade UDS created during the week until Saturday morning instead of end of day Friday, for markets that support 24/7 trading schedules.

Please Note: The UDS' LTD cannot exceed the LTD of any of the legs. When the LTD of any leg occurs before the LTD of the UDS, the UDS' LTD will be set equal to the LTD of the nearest leg.

The LTD is captured in the MDP 3.0 Security Definition message in repeating group 864, 865=7 and 1145=LTD.

These changes are currently available for customer testing in New Release. CME Group strongly recommends clients test this new LTD and UDS elimination timings to ensure no impacts.

NewImportant Updates to CME Globex Migration to Google Cloud - Starting June

As we accelerate the transition of CME Globex to Google Cloud, we are providing substantive updates to our roadmap and technical requirements. Clients are strongly encouraged to complete a comprehensive review of these updates to ensure uninterrupted market access and readiness for the upcoming migrations.

Detailed technical documentation has been updated in the Client Systems Wiki.

The Livestock Migration - Dallas Region Q4 2026

To provide clients with a real-world Production environment on Google Cloud prior to the Chicago region launch, Livestock futures and options will migrate to a new Production environment in the private zones of the Dallas region in Q4 2026. In the second half of 2028, Livestock futures and options will migrate to the Production-Chicago environment, in the private Google Cloud Chicago region.

The Livestock Migration - Dallas Region
Key Events and Timing	Source Environment	Destination Environment	Primary Purpose
First Migration Target: Q4 2026	On-premise Production-Aurora environment	Production-Dallas environment in the private zones of the Google Cloud Dallas region	Enable real-world Production trading on Google Cloud infrastructure.
Second Migration Target: H2 2028	Production-Dallas environment in the private zones of the Google Cloud Dallas region	Production-Chicago environment in the private Google Cloud Chicago region	Migration to the long-term cloud platform.

Key Note: The Production-Dallas environment will be accessible via all current market access solutions and the new GLink ULL and GLink Premium solutions for Ultra Low Latency Google Compute Engine (ULL GCE) Instances.

Connectivity and Performance

As we move toward a cloud-native future, the way clients connect matters more than ever.

GLink ULL-Dallas and the U4C Bare Metal instances will be the lowest-latency access method available for the environments hosted in the Dallas region.

The Chicago Region Migration - Starting in 2027

CME Globex Production markets will begin migrating to the new Google Cloud Chicago Region in late 2027.

The Chicago Region Migration
Phase	Environment	Timeline
Globex Migration to Google Cloud Chicago Region	Production-Chicago	Late 2027-2028
Convenience Gateway and Drop Copy Migrations	Production-Chicago	2029

Connectivity and Performance

• Physical Co-location
  • CME Group is committed to continuing to offer physical co-location market access to the Chicago region. 
  • Throughout the migration of markets to Google Cloud, our current GLink Aurora co-location offering will continue as the only physical co-location service. 
    • GLink Aurora will continue to offer the most performant access to markets hosted in the Chicago region through the end of the market migrations in 2028.
  • CME Group is currently evaluating the Customer Hardware Co-location (CHC) offering to ensure our infrastructure aligns with evolving market requirements and client demand. A definitive decision regarding the physical co-location site will be announced no later than the end of 2028.
• Cloud-Native Access 
  • After the Globex migration to the Chicago region is complete, GLink ULL-Chicago and the U4C Bare Metal instances in the Chicago region will be competitive with physical co-location (GLink in Aurora and/or CHC) for clients who use traditional compute. 

We remain committed to performance transparency. CME Globex application timestamps will continue to provide meaningful latency insight.

Sandbox Launch

• The Sandbox-Dallas environment opens in June. This is a critical early-access window for clients to validate their cloud journey and connectivity solutions. 

Sandbox-Dallas Pilot and Incentive Programs

• CME Group is offering a Pilot Program for clients who achieve specific technical milestones. 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 Field Sales Representatives (FSR). To support the migration and the testing of U4 machines specifically, Google Cloud customers may opt into a Google Cloud incentive program that provides up to $30,000 in credits for U4 compute usage. More information on this program is available from your FSR or contact exchanges@google.com.

Google Cloud ULL Solution Documentation

Google Cloud has released its first wave of ULL solution documentation. It is available now to all clients.

Position Reporting Under CFTC Part 17

On April 30, 2024, the Commodity Futures Trading Commission ("CFTC") approved final rules to amend its Large Trading Reporting Regulations for Futures and Options. The amendments were made to modernize CFTC's Large Trader Reporting process and align it with other reporting structures outlined in CFTC regulations.

Since October 2024, CME Group has offered methods to retrieve its instrument listing containing the Unique Instrument Code (UIC) and other instrument data elements in compliance with the amended rule.

Starting March 10, 2025, CME Group began accepting test files in the new Position Message FIXML format via SFTP. For details regarding submitting the new FIXML Position Message, file management, field validations, and example scenarios, please refer to the information in the CME Group Client Systems Wiki.

The Market Regulation Department will be publishing further guidance regarding Large Trader Reporting in subsequent Special Executive Reports as solutions become available.

CFTC's final rules became effective upon publication in the Federal Register on June 3, 2024. Subject to the conditions of the January 27, 2026, no-action letter, reporting firms must comply with these CFTC regulations by July 26, 2027.

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.
