SEC Initiates Comprehensive Review of the Consolidated Audit Trail
Securities and Exchange Commission
On April 16, 2026, the Securities and Exchange Commission issued a concept release soliciting public comment in support of a comprehensive review of the Consolidated Audit Trail (CAT) and other related market data sources.
The public comment period will remain open for a strict 60-day window following the document's formal publication in the Federal Register.
The concept release serves as a formal administrative vehicle for the Commission to obtain public input on policy topics prior to pursuing any related regulatory action.
The SEC is actively seeking targeted feedback on the CAT's funding mechanisms, cost management, structural governance, and core regulatory purpose.
Furthermore, the release requests specific evaluations regarding the design, scope, cybersecurity protocols, and data privacy frameworks of the CAT and other audit trails.
The Commission is soliciting guidance on how to appropriately balance regulatory market needs with civil liberties, privacy, and confidentiality considerations.
Commenters are explicitly asked to propose regulatory responses and detail the specific costs, burdens, or benefits that may result from their implementation.
Operationally, this action opens a direct channel for financial institutions, legal professionals, and market participants to influence foundational and existential changes to the national market system's surveillance infrastructure.
The release itself does not alter immediate compliance standards but rather identifies potential options and raises specific questions for future rulemaking.
This comprehensive review expands upon recent Commission amendments that permanently eliminated the reporting of personal identifiable information to the CAT and reduced its projected annual operating costs by over $100 million.
The jurisdictional scope of the review explicitly covers the entirety of the Consolidated Audit Trail, alongside any other audit trails and related data sources currently utilized to regulate U.S. securities markets.
The process is fully public, allowing any interested party to submit responses and potential regulatory solutions within the designated 60-day period.
