New RTP Time‑in‑Force Spans Regular and Post‑Close
EDGA is adding a new Time‑in‑Force called “Regular `til Post Market” (RTP). An RTP limit order is eligible for execution during Regular Trading Hours (9:30 a.m. to 4:00 p.m. ET) and, if not fully executed, remains active for the Post‑Closing Session (4:00 p.m. to 8:00 p.m. ET) and expires at the end of the Post‑Closing Session.
RTP Subject to 7:00 a.m. Entry Restrictions
The Exchange amends Rule 11.1 so that orders with a Time‑in‑Force of RTP are not accepted prior to 7:00 a.m. Eastern Time when combined with certain instructions. Specifically, Market Orders with a TIF of RTP and orders with a Minimum Execution Quantity instruction that also include a TIF of RTP will not be accepted before 7:00 a.m. ET.
RTP Integrated into Opening/Re‑Opening Rules
EDGA will allow Users to enter RTP orders to participate in the Opening Process prior to the Regular Session and will treat RTP orders the same as Regular Hours Only (RHO) orders for Opening and Re‑Opening Process eligibility and applicable restrictions (including prohibitions on EDGA Post Only Orders, ISOs, and Minimum Execution Quantity orders participating in the Opening Process).
RTP Available Across Multiple Order Types
The Exchange adds RTP as a permissible Time‑in‑Force for multiple order types, including Limit Orders, Intermarket Sweep Orders (ISOs), MidPoint Peg Orders, MidPoint Discretionary Orders, Market Maker Peg Orders, and Supplemental Peg Orders. The rule filing also adds references to RHO where previously omitted to align treatment across similar TIFs.

2026-18424, Political Contributions by Certain Investment Advisers
The Securities and Exchange Commission (the "Commission" or the "SEC") is proposing to rescind the political contribution rule under the Investment Advisers Act of 1940 (the "Advisers Act"), which prohibits investment advisers from providing investment advisory services for compensation to a government client for two years after an adviser or any covered associate of the adviser makes a contribution to certain categories of elected officials or candidates, among other prohibitions. In the more than fifteen years since the rule was adopted, implementation challenges associated with the political contribution rule have resulted in a range of significant unintended consequences, including compliance practices among some investment advisers that may have had the effect of restricting all political contributions by the investment advisers and their employees. Market participants also have stated that the political contribution rule is burdensome, complex, and both lacks clarity and creates a de facto strict liability standard. The Commission is of the view that other existing requirements of the Advisers Act and its associated rules, including prohibitions on fraud, fiduciary duty requirements, the compliance rule, and the code of ethics rule (defined below), are likely sufficient to address pay-to-play practices while allowing an adviser the flexibility to implement an approach that is more appropriately tailored to its particular risks, rendering the political contribution rule unnecessary. The Commission also is proposing to amend the rule under the Advisers Act pertaining to books and records consistent with the proposed rescission.
2026-18190, Transfer Agent Rules
The U.S. Securities and Exchange Commission ("SEC" or "Commission") is proposing to adopt new rules, amend existing rules, amend the existing form for registration with the Commission as a transfer agent (Form TA-1) and the existing form for reporting activities of transfer agents (Form TA-2), and rescind an existing rule governing registered transfer agents. The proposals are designed to modernize the rules governing registered transfer agents.
2026-17183, Regulation Crypto Assets
The Securities and Exchange Commission ("Commission") is proposing new rules to create a tailored offering regime for certain investment contracts involving crypto assets. The proposed offering regime is intended to facilitate capital formation and accommodate innovation within the crypto asset markets while, at the same time, ensuring that investors are adequately protected and provided with the information they need to make informed investment decisions. The proposed rules would be set forth in a new regulation titled "Regulation Crypto Assets" and would include two exemptions from the registration requirements of section 5 of the Securities Act of 1933. The first exemption would permit offerings of up to $5 million during a four-year period. The second exemption would permit offerings of up to $75 million during each 12-month period. Under both exemptions, issuers would be required to make certain principles-based narrative disclosures available to their investors. In addition, issuers under the second exemption would be required to provide financial statements and would be subject to ongoing reporting requirements. Issuers that rely on these exemptions would remain subject to the antifraud and antimanipulation provisions of the Federal securities laws. The proposed rules also would include a conditional safe harbor from the term "investment contract" in the definitions of "security" in the Securities Act of 1933 and the Securities Exchange Act of 1934. If the conditions of that proposed safe harbor are satisfied, then a crypto asset would be deemed not to be subject to an investment contract for purposes of those definitions of "security."
