Nasdaq PHLX connectivity rule change takes effect after SEC filing
Nasdaq PHLX is updating its connectivity rulebook after filing changes with the U.S. Securities and Exchange Commission on May 29, 2026. The revisions remove unused services and revise technical terminology, while taking immediate effect under the Exchange Act framework.
Highlights
- Nasdaq PHLX amended Rule General 8 to remove obsolete connectivity services and update technical references in its fee schedule, effective immediately.
- The exchange cited removal due to lack of users and minimal demand, confirming all changes apply equally regardless of participant type or size.
- The SEC filing under Section 19(b)(3)(A)(iii) and Rule 19b-4(f)(6) allows immediate effect, as the rule change poses no significant investor protection concerns.
Rule update removes obsolete services
As reported by the Securities and Exchange Commission, Nasdaq PHLX filed a proposed rule change to amend Rule General 8, which governs connectivity services on the exchange. The filing covers the removal of offerings that are no longer used by customers and updates references to technical specifications in the connectivity fee schedule.The exchange says the services are being removed because of a lack of users and limited demand. It also states that the terminology changes are intended to improve clarity in how technical specifications are described.
Market impact and regulatory basis
Nasdaq PHLX says the proposal is consistent with Section 6(b) of the Securities Exchange Act of 1934, particularly the requirement to promote just and equitable principles of trade and support a free and open market. The exchange adds that the changes apply equally to all customers and do not differentiate by participant type or size.No written comments were solicited or received on the proposal. Because the rule change does not significantly affect investor protection or the public interest, it becomes effective immediately under Section 19(b)(3)(A)(iii) and Rule 19b-4(f)(6).

The analysis highlighted mixed momentum signals and key levels to watch, with $29,133 as a near-term pivot and downside risk increasing if support around $27,562 gave way.
