Registered Exchange
A registered exchange is a trading venue formally registered with the SEC under Section 6 of the Securities Exchange Act of 1934, meeting statutory requirements for fair and orderly markets, investor protection, and SRO governance, and thereby authorized to operate as a national securities exchange with all associated regulatory obligations and privileges.
Registration as a national securities exchange is the highest regulatory designation in U.S. equity markets. As of recent years, the SEC recognizes more than twenty registered national securities exchanges across equities and options, a significant increase from the handful that existed before market structure fragmentation accelerated in the 2000s. Major equity exchanges include the New York Stock Exchange and its affiliated venues (NYSE American, NYSE Arca, NYSE National, NYSE Chicago), the NASDAQ Stock Market and its tiers, and Cboe Global Markets' multiple exchange registrations.
The legal obligations of a registered exchange are substantial. Under the Exchange Act, a registered exchange must enforce compliance by its members with the Exchange Act and SEC rules, must promulgate rules designed to prevent fraudulent and manipulative acts, must not impose unfair membership standards, and must provide fair procedures for disciplining, suspending, or expelling members. All exchange rules must be filed with the SEC, and material rule changes require advance notice and SEC approval or effective review.
Registered exchanges have exclusive authority to operate as the primary listing venue for NMS stocks. A company's shares can be listed only on a registered exchange; ATS and other trading venues may trade listed stocks in the secondary market but cannot be the listing venue. This gives registered exchanges a revenue stream from listing fees and creates competitive incentives for exchanges to attract IPOs and transfer listings from competing venues.
Exchange registration also confers certain competitive advantages. Registered exchanges can operate 'lit' markets with publicly displayed quotes that are protected under Regulation NMS Rule 611 — meaning orders cannot be traded through their best quotes without routing to them. ATSs that display quotes in the consolidated feed do not have their quotes automatically protected as registered exchange quotes are.
The proliferation of registered exchanges has intensified competition for order flow through exchange fee structures, rebate programs for liquidity providers, and technology infrastructure investments. Critics argue that this fragmentation has increased complexity, created opportunities for latency arbitrage, and made it difficult for regulators and investors to fully understand aggregate market dynamics across more than twenty competing venues.
