About this source
This feed pulls every final notice posted to regulations.gov across all federal agencies, around 240 a month. Final notices are the binding step in the federal rulemaking cycle: a final rule, a no-action determination, a self-regulatory organization rule change, or a procedural notice that takes effect on publication. Watch this for the actionable end of the rulemaking pipeline rather than the proposed-and-comment phase. GovPing publishes each notice with the issuing agency, docket ID, effective date where stated, and document type. Recent examples include Nasdaq ISE auction rule changes and an NYSE proposal enabling tokenized securities trading under the DTC pilot.
