Alternative Trading System (ATS) List

Published by U.S. Securities and Exchange Commission | Securities and Exchange Commission | Catalog Last Checked: October 01, 2026 at 07:42 PM | Dataset Last Updated: August 12, 2024 at 03:01 PM
Regulation ATS creates a regulatory structure for alternative trading systems, allowing them to operate as exchanges without registering as national securities exchanges if they comply with specific rules. ATSs must register as broker‑dealers, file Form ATS before beginning operations, and submit amendments or cessation notices as their operations change, noting that Form ATS serves only as a notice to the SEC rather than an application. The SEC maintains and updates a public list of ATSs based on these filings, and a separate list exists for ATSs that file Form ATS‑N to trade NMS stocks. The SEC receives submissions from ATSs on an ongoing basis pursuant to Regulation ATS. We note that the list of ATSs changes over time. Commission staff expects to update the list monthly.
