On June 11, 2026, the U.S. Securities and Exchange Commission announced it proposed amendments to rescind Rules 611 and 610(e) of Regulation NMS, with Rule 611 containing the trade-through prohibition for national market system stocks and Rule 610(e) containing restrictions on locking and crossing quotations in national market system stocks. The proposal would also rescind related defined terms in Rule 600 of Regulation NMS and make conforming changes to other related provisions. SEC Chairman Paul S. Atkins stated that the proposal is intended to simplify market structure and reduce costs for market participants while allowing competition, innovation, and other market forces to shape the continuing evolution of equity markets, and said he looks forward to reviewing public comments. The Commission stated that the public comment period will remain open for 60 days following publication of the proposing release in the Federal Register.
