Do options trade after hours? Premarket and extended sessions
Learn which U.S. options can trade before or after regular hours, how equity, ETF, and index sessions differ, and why symbol eligibility, broker access, liquidity, orders, and expiration matter.

Direct answer
Some options trade before or after the regular U.S. session, but there is no universal after-hours market for every contract. Eligibility depends on the exact option class, series, exchange session, date, and broker. Designated index products can have global and curb sessions, certain ETF options trade later than ordinary equities, and Cboe now offers extended sessions for selected eligible single-stock options. A stock trading after hours does not by itself make every option on that stock tradable.
Regular hours are only the starting assumption
Many multi-listed U.S. equity options use a regular session aligned broadly with the stock market. Other products do not. Selected ETF and index options may remain open later, while designated proprietary index options can trade in global sessions approaching 24 hours on business days.
As of this review, Cboe also provides a morning Global Trading Hours session and an afternoon Curb session for selected eligible equity option classes. The eligible symbols and launch details can change. Therefore, an old statement that single-stock options never trade outside regular hours is too broad, while saying that all stock options now trade extended hours is equally wrong.
Order acceptance is not the same as an open market
An exchange may accept and queue an order before a session opens without allowing an immediate execution. Orders can also carry session instructions such as regular-hours only or eligibility for global and curb sessions. A broker may not expose every exchange session or order type to every account.
Check the option symbol and exact series, the exchange's current hours page, session designation, supported order types, holiday schedule, and the broker's trading permissions. Convert the published exchange time zone carefully and account for daylight-saving differences when trading from another country.
Extended-hours execution can behave differently
Fewer participants and less displayed size can produce wider bid-ask spreads, more slippage, and slower or partial fills. The underlying cash market may be closed or thinner, making hedging and fair-value estimates less certain. A midpoint or stale last price is not proof that the option can trade there.
Use limit prices rather than assuming a market order will resemble the regular-session quote. Review the live bid, ask, size, session indicator, and underlying reference. If the spread cannot be justified, waiting for the more liquid session can be a valid risk decision.
Expiration hours require a separate check
The standard hours for a class do not necessarily describe its expiring series. AM-settled index options can stop trading before the morning settlement calculation, while PM-settled series may have a special expiration cutoff. Half-days and holidays can shorten the schedule.
Trading hours also do not define the broker's exercise-instruction deadline. Confirm the final tradable time, expiration style, settlement method, and exercise procedure independently. A pending order that never fills leaves the contract open under its normal expiration rules.
Common questions
Can I trade stock options after 4:00 p.m. Eastern Time?
Only some. Selected ETF options have long traded beyond the ordinary equity-option close, and Cboe offers a curb session for designated eligible single-stock option classes. Other contracts may be closed even while their underlying shares trade after hours. Verify the current symbol list, exchange session, expiration status, holiday schedule, and whether your broker permits that session before relying on an exit.
Can I buy options during premarket stock trading?
Potentially, but not merely because the stock is trading. Certain designated equity options and proprietary index options have morning or global sessions, while many contracts do not. An order entered early may also be queued for a later opening rather than executed immediately. Confirm that the exact option class is open and that the order is marked for a session your broker supports.
Are SPX and index options available nearly 24 hours a day?
Some Cboe proprietary index options, including designated SPX, XSP, VIX, and RUT classes, have Global Trading Hours in addition to regular and curb sessions. Nearly 24-hour access still contains session breaks, holiday changes, product-specific expiration cutoffs, and broker restrictions. It does not mean every index option worldwide or every listed series trades continuously at identical liquidity.
Why is my after-hours option order not filling?
The contract may be ineligible, the order may be queued for another session, or the broker may not support that exchange window. If the market is open, the limit may still be outside a wider bid-ask spread or available size may be small. Check session status, order instructions, live bid and ask, quoted size, halt notices, and expiration hours instead of relying on the stock's after-hours price alone.
