Notice
Summary
Cboe Exchange is updating its rules to let traders buy and sell Russell 2000 and Mini-Russell 2000 options during both Global Trading Hours and Curb Trading Hours. This change means more trading opportunities for investors outside regular hours, starting right away with no extra fees. If you trade these options, get ready for more flexibility and action!
Analyzed Economic Effects
4 provisions identified: 4 benefits, 0 costs, 0 mixed.
RUT & MRUT Trade Hours Extended
You can trade Russell 2000 (RUT) and Mini-Russell 2000 (MRUT) index options outside regular hours because the Exchange may list and trade these products during Global Trading Hours (8:15 p.m. previous day to 9:25 a.m. Monday–Friday) and during Curb Trading Hours (4:15 p.m. to 5:00 p.m. Monday–Friday). The change was filed on September 26, 2025 and the Exchange may operate these extended hours for RUT and MRUT in the same way it does for SPX, VIX, and XSP.
Extended Hours Increase Futures Overlap for Hedging
Extending RUT and MRUT trading into Global Trading Hours and Curb increases the time these options overlap with related futures (for example, E-mini Russell 2000 contracts), which the Exchange says lets global participants hedge and respond to macroeconomic events nearly around the clock.
Broker Duties Continue During Extended Hours
If you use a broker to trade during Global Trading Hours (8:15 p.m. previous day to 9:25 a.m.) or Curb (4:15 p.m. to 5:00 p.m.), your broker's business conduct rules, due diligence, and best execution obligations continue to apply during those sessions. The Exchange states existing Chapter 8 and Chapter 9 rules will remain in force for GTH.
TPHs Can Trade RUT/MRUT But Not Required
All Trading Permit Holders (TPHs) will be able, but are not required, to trade RUT and MRUT options during Global Trading Hours and Curb. The Exchange says the change merely extends permissible trading hours for products that already trade during Regular Trading Hours.

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."
