Nasdaq MRX files rule change on intrafirm cabinet connectivity fees
Nasdaq MRX is seeking to revise how non-contiguous intrafirm cabinet connectivity is categorized and priced within its exchange infrastructure rules. The filing, submitted on May 26, 2026, would move the service more clearly under Fiber connectivity provisions and reduce reliance on third-party fiber inside the exchange's data center halls.
Highlights
- Nasdaq MRX proposes to add Intrafirm Cabinet Connectivity to the Fiber category and eliminate non-contiguous options under custom installations.
- The amendment aims to reduce reliance on third-party intrafirm cabinet fiber by transitioning components to direct Nasdaq administration within its data center halls.
- By implementing this rule change, MRX seeks to strengthen system integrity and gain clearer control over infrastructure service delivery and the related fees.
Operational impact for exchange infrastructure
MRX says the amendment would formally add Intrafirm Cabinet Connectivity to the Fiber category and remove the availability of non-contiguous intrafirm cabinet connectivity under the custom installation provision in Section 1(d).The exchange says the change would strengthen the integrity of its systems by reducing dependence on third-party provided intrafirm cabinet fiber within its data center halls. By shifting those connectivity components under Nasdaq's direct administration, the proposal is aimed at giving the exchange clearer control over infrastructure service delivery and the related fee structure.
