Nasdaq connectivity rule update

Highlights

Nasdaq filed a rule change on May 29, 2026, amending Rule General 8 to remove unused connectivity services and improve technical terminology.
The eliminated market data feeds and services, which no customers subscribed to since August 2023, will be deleted, with no fee changes impacting data center clients.
The proposal, effective immediately under Section 19(b)(3)(A)(iii), targets administrative updates without altering customer pricing, access, or investor protections.

Rule changes target unused feeds and technical terms

As published by the Securities and Exchange Commission, Nasdaq filed the proposed rule change on May 29, 2026, to amend Rule General 8 on connectivity services. The exchange says the revisions remove offerings that are no longer in use and update references to technical specifications to improve precision and readability.

Nasdaq proposes to delete certain market data feeds, related services and associated fees from subsection 1(b) of Rule General 8. The exchange says no customers have subscribed to the affected feeds and services since or about August 2023.

The filing states the changes do not apply differently to distinct types or sizes of market participants. Nasdaq says connectivity products and services remain voluntary, and the fee schedule continues to apply uniformly across all of its data center customers.

Immediate effectiveness and market impact

Under Section 19(b)(3)(A)(iii) of the Securities Exchange Act and Rule 19b-4, the proposal becomes effective immediately because it does not significantly affect investor protection or the public interest. The SEC is publishing the notice to solicit comments from interested parties.

For market participants, the amendment appears focused on administrative cleanup rather than a broader pricing or access overhaul. By removing dormant offerings and clarifying technical language, Nasdaq is streamlining its connectivity framework while keeping the current approach to customer treatment and fees in place.

Our earlier Nasdaq 100 (NDX) technical outlook highlighted that the index had slipped below its 20-day moving average amid elevated short-term selling pressure, while still holding above its 50-day and 200-day averages. The analysis pointed to mixed momentum signals and identified key levels to watch, with a potential rebound scenario if support held and a deeper pullback risk if it failed.
