Cboe Wins Approval for Longer Equity Options Hours
Published Date: 6/2/2026
Notice
Summary
Cboe Exchange got the green light to let traders buy and sell certain popular stock options for longer hours. This change affects investors who trade multi-listed equity options, giving them more time to make moves outside regular market hours. The new extended trading sessions could mean more chances to react to news and potentially more trading activity starting soon.
Analyzed Economic Effects
7 provisions identified: 3 benefits, 0 costs, 4 mixed.
Equity Options: Longer Trading Hours
Cboe is allowed to offer extended trading for certain multi-listed equity options Monday through Friday in two new windows: a morning session from 7:30 a.m. to 9:25 a.m., and an afternoon Curb session from 4:00 p.m. to 4:15 p.m. This change lets investors trade those eligible equity options outside the regular 9:30 a.m.–4:00 p.m. hours.
Only Biggest, Most Liquid Options Qualify
Up to 100 equity option classes may be designated for the extended sessions, and each must meet six-month minimums: average daily option volume of 150,000 contracts, underlying company market capitalization of $50 billion, and underlying average daily share volume of 10 million shares. Options already trading on another exchange during extended hours may be added without counting toward the 100-class cap.
FLEX Equity Options Included
If the Exchange designates a class of equity options as eligible for the extended morning or Curb sessions, FLEX options with the same underlying equity will also be eligible to trade in those extended sessions. That means customizable (FLEX) equity option orders tied to approved underlying securities can trade in the new windows.
Trading Mechanic Rules For Extended Sessions
During the proposed extended sessions, market orders would not be permitted for equity options and order routing will be available across sessions (the Exchange changes routing availability to begin at 'market open'). Opening auction queuing for GTH equity options would begin at 7:15 a.m., and equity FLEX orders designated for GTH may be submitted after 7:30 a.m. and after 4:00 p.m. for the Curb session.
Semiannual Eligibility Reviews and Start Dates
The Exchange will review eligibility semiannually using the prior six months of data on January 1 and July 1. Eligible classes determined in those reviews may start trading in the extended morning and Curb sessions on the first trading day of February and August, respectively.
Removal Process and Notice Periods
If an equity option no longer meets eligibility, the Exchange may continue trading it in extended sessions for up to 18 months and will provide advance notice of the removal date; notices can be accelerated with at least seven days' notice, other discretionary removals require at least 30 days' notice, and immediate removal is allowed for investor protection or fair and orderly market reasons.
Disclosure: Lack Of Underlying Price During Extended Hours
The Exchange updated customer disclosure rules (Rule 9.20) so Trading Permit Holders must inform customers that during the proposed GTH and Curb sessions equity options may trade when there is no updated underlying price or regular trading in the underlying equity. This tells customers about the risks of trading options when the underlying may not be actively quoted.

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."
