CBOE’s extended trading hours for single-stock options launch July 13, 2026, five trading days from today. The mechanics have been public since the SEC approval closed in early June, but the final operational details, the ones that actually determine whether your order fills or your position gets stuck, are easy to miss. Here’s what’s confirmed, what’s genuinely new since the initial announcement, and how to be ready before Monday.
- Launch date is locked: July 13, 2026. Pre-market session runs 7:30 AM to 9:25 AM ET; post-market session runs 4:00 PM to 4:15 PM ET, Monday through Friday.
- Only about 20 names qualify at launch: all seven Magnificent Seven stocks (NVDA, TSLA, AAPL, MSFT, META, GOOGL, AMZN), plus PLTR, AVGO, and AMD.
- Only limit orders are accepted in both extended sessions. Market, stop, and stop-limit orders are rejected outright.
- The post-market window gives expiring option holders a 15-minute chance to close a position instead of being forced into assignment, useful when a stock reacts hard to an after-hours earnings print right at the close.
- Broker support is not guaranteed on day one. Confirm your platform’s status before assuming you’ll have access July 13.
What’s Actually New Since the Original Announcement
CBOE’s rule change cleared SEC review in early June 2026. Since then, two things have firmed up that weren’t settled when the proposal first circulated: the exact 20-name eligible list (previously described as “approximately 20,” now confirmed) and CBOE’s own statement that it has heard from the vast majority of market makers and from multiple consolidators and retail-facing brokers that they expect to be ready for launch day. That’s a meaningfully stronger signal than the earlier “we’ll see who adopts it” framing.
What hasn’t changed: this is still a narrow expansion. It covers a specific list of the highest-volume, highest-market-cap single-stock names, not a general options market extension. If you trade options on anything outside that list, mid-caps, sector ETFs, most single stocks, none of this applies to you on July 13.
The Eligible List and Why It’s Still Short
To qualify, an underlying’s options must clear three thresholds over the preceding six months:
- 150,000 or more average daily contracts traded
- $50 billion or higher underlying market capitalization
- 10 million or more average daily shares traded in the underlying
That bar currently produces roughly 20 qualifying names: the full Magnificent Seven (NVDA, TSLA, AAPL, MSFT, META, GOOGL, AMZN), plus PLTR, AVGO, and AMD. CBOE plans to refresh the list twice a year, once using data through June 30 and once through December 31, so names can be added (or in theory dropped) as liquidity shifts. If you trade options outside this list today, don’t expect that to change soon; the thresholds are deliberately set high enough to keep market makers comfortable quoting through thinner sessions.
The Order-Type Rule That Will Trip People Up
This is the detail most likely to cause a bad fill or a rejected order on launch day: CBOE’s extended sessions accept limit orders only. Market orders, stop orders, and stop-limit orders are not accepted in either the pre-market or post-market window. If your usual workflow includes a stop-loss or a market order to get filled fast, that order type simply won’t route during extended hours, full stop.
Practically, that means you need a specific price in mind before you place any order between 7:30 and 9:25 AM ET or 4:00 and 4:15 PM ET. Market makers also get some latitude during these sessions: for in-the-money series, they’re permitted to quote as wide as the underlying stock’s own spread when that width exceeds $5, at least in the initial rollout, before CBOE’s planned maximum quote-width requirements (generally capped around $5, with wider allowances for LEAPS) take effect. Combine those two facts and the takeaway is simple: check the quoted spread before you send an order, and don’t assume a limit price close to the last regular-hours print will fill.
Liquidity Reality Check
Extended-hours liquidity in the underlying stocks themselves is already thinner than regular session. CBOE’s own guidance acknowledges this directly, noting that reduced trading activity in the pre-market underlying can lead to more manual intervention from market makers managing risk in the option quotes. Translate that: expect wider markets, slower quote updates, and less depth than you’re used to seeing at 10 AM on a normal Tuesday, especially in the first weeks after launch while market makers calibrate.
The 4:00 to 4:15 PM window carries an extra wrinkle. Most large-cap names that report earnings after the close do so around 4:05 to 4:15 PM ET, meaning the busiest 60 seconds of that entire window can also be the most volatile. A hypothetical illustration: if NVDA reports at 4:08 PM and the stock immediately swings 4% on the print, the option quotes in that first minute or two are likely to be exceptionally wide before market makers reprice. Waiting even 3 to 5 minutes for spreads to settle, rather than chasing the first quote you see, is a reasonable approach based on how extended-hours equity trading has behaved historically.
Session Comparison: Regular Hours vs. the Two New Windows
| Session | Hours (ET) | Order types allowed | Typical liquidity |
|---|---|---|---|
| Pre-market (new) | 7:30 AM, 9:25 AM | Limit only | Thin; wider spreads likely, especially in the first minutes |
| Regular session | 9:30 AM, 4:00 PM | All standard order types | Normal, deepest of the trading day |
| Post-market / “Curb” (new) | 4:00 PM, 4:15 PM | Limit only | Very thin 15-minute window; volatile in the first 1-2 minutes after AMC earnings |
The Contra-Exercise Wrinkle Nobody’s Covered Yet
Here’s the angle that’s easy to miss in the broader coverage of this launch: single-stock equity options are American-style and physically settled, meaning an in-the-money option that expires gets exercised into actual shares unless the holder closes it first. Under the old regular-hours-only system, if you held an expiring option into an after-hours earnings report, you had no way to react. The 4:00 PM close locked in your exercise decision, and if the stock then moved hard on the earnings print, you were stuck with whatever assignment resulted, with zero ability to adjust until the next morning’s open.
The new Curb session changes that math. Because expiring single-stock options can now trade through 4:15 PM on expiration day, a trader holding a marginal in-the-money position into an AMC earnings report gets a real, if narrow, window to close out rather than get automatically assigned or exercised based on a closing price that’s about to be stale.
Consider a hypothetical: a trader holds a slightly in-the-money NVDA call expiring that same day, and NVDA reports earnings at 4:06 PM before immediately reversing lower after an initial pop. Under the old system, that position would be locked in for exercise at the 4:00 PM close, with no way to react until Monday’s open. Under the new rules, the trader has until 4:15 PM to sell the call in the open market instead of taking assignment on shares they may not want at a price that’s already stale. It reduces, though doesn’t eliminate, the contra-exercise risk that’s long been a real headache around AMC earnings on expiration day.
What This Means for Positioning Ahead of Macro Data
To be clear on scope: the extended sessions don’t change when same-day options expire, they still settle at the regular 4:00 PM close, same as always. What they do change is when you can first enter a position on an eligible name. Previously, the earliest you could open or adjust an options position was 9:30 AM ET, by which point a scheduled 8:30 AM release like CPI or the jobs report had already been fully digested by the market for a full hour.
Starting July 13, the pre-market window opens at 7:30 AM, a full hour before that 8:30 AM data release and two hours before the old 9:30 AM start. For a trader on one of the eligible names who wants to position ahead of a known macro catalyst rather than chase the move after the fact, that’s a genuinely new capability, not a workaround. It comes with the liquidity caveats above: thin pre-market markets, limit orders only, and spreads that may not tighten until closer to the regular open.
It’s also worth being precise about what this isn’t. CBOE’s single-stock extended hours expansion is separate from the existing near-24-hour access that SPX and other index options already have through CBOE’s Global Trading Hours program. If your primary 0DTE strategy runs on SPX rather than single names, this launch doesn’t change your setup directly, though the liquidity and order-type lessons from the single-stock rollout are a useful preview of how index extended-hours sessions tend to behave.
Bottom Line
The mechanics are locked, the eligible list is confirmed at roughly 20 names, and CBOE says the market-maker and broker ecosystem is largely ready. The two details worth remembering before Monday are the limit-order-only rule and the new 15-minute close-out window on expiration day. Confirm your broker actually supports extended-hours options before July 13 rather than assuming it does.
FAQ
Q: Does the CBOE extended hours expansion include SPX or other index options?
A: No. This launch is specifically for eligible multi-listed single-stock equity options. SPX and other CBOE index options operate under a separate, pre-existing extended hours framework.
Q: Can I place a market order during the pre-market or post-market session?
A: No. Both extended sessions accept limit orders only. Market, stop, and stop-limit orders are not accepted and will be rejected.
Q: Will every broker support extended hours options on July 13?
A: Not necessarily. CBOE’s approval means the exchange can offer the sessions; each broker still has to implement support on its own platform. Check your broker’s own announcements before the launch date rather than assuming access.
Q: Does trading in the pre-market session change when my option expires?
A: No. Expiration and settlement timing are unchanged. The pre-market window only changes when you can first place an order on an eligible name; same-day options still settle based on the regular 4:00 PM close.
Q: Why does the 4:00 to 4:15 PM window matter if it’s only 15 minutes?
A: Because single-stock options are physically settled, a marginal in-the-money position expiring that day would previously lock in exercise at the 4:00 PM close with no way to react to an after-hours earnings surprise. The 15-minute Curb session gives holders a narrow chance to close the position instead.
