Standard monthly SPX options stop trading on Thursday afternoon before the third Friday of the month. This early cutoff often surprises traders who expect to manage positions through the Friday bell. Knowing when do SPX options expire, and which settlement method applies, is as important as choosing a price target.

Trading the S&P 500 index requires respect for market hours and settlement rules. The guide below explains the timing for each contract and the practical checks to make before participating.

When do SPX options expire?

Knowing when SPX options expire is a key skill for any trader. These contracts do not all follow the same plan. Instead, they expire on many days during the week and month. Most traders focus on the daily, weekly, and monthly times to plan their trades. The S&P 500 Index (SPX) gives you many ways to meet your goals when trading SPX options for income or growth.

Monthly and weekly cycles

Standard monthly SPX options expire on the third Friday of each month. These are the classic contracts that many big firms use for their trades. Weekly SPX options, often called SPXW, fill the gaps between these monthly dates. They expire on all other Fridays. Now, you can find SPXW contracts that expire every single trading day of the week.

This daily cycle has led to the rise of zero days to expiration (0DTE) trading. These 0DTE contracts make up a huge part of the market volume now. They allow traders to react to news and price moves very fast. Our teammates use these to find daily market chances. Because SPX options use European-style exercise, you do not face the risk of early assignment.

AM versus PM settlement

One key detail to check is the settlement type. Standard monthly options are AM-settled. This means their final value is set by the opening prices on Friday morning. Trading for these contracts stops on Thursday. You must close your trade before the Thursday bell if you want to avoid the gap risk overnight.

Most weekly and daily options are PM-settled. These contracts expire at the close of trading at 4:00 PM ET on the expiration day. Trading for these SPXW options usually stops at the same time. It is vital to know how SPX options settlement works so you can manage your risk with care.

Quarterly and holiday changes

Quarterly SPX options are also found for your long-term views. These expire on the last trading day of each calendar quarter. If a holiday falls on a Friday, the end day moves to the prior business day. Always check your broker to confirm the exact date for each trade. Since these are cash-settled options, you will get or pay cash instead of stock at the end.

Dr. Rolf Haag and the team stress the need for a set system. Trading SPX options involves big risk and is not right for all people. You should have a clear plan before you enter any trade. Past performance does not promise future results. Options trading involves risk, and you should only trade with money you can afford to lose.

AM-settled vs. PM-settled SPX options

Traders must know the split between morning and afternoon settlement when they choose when do spx options expire. Normal monthly trades use AM rules, while weekly and daily trades mostly use PM rules. This shift in timing changes how you control risk and when you can last trade. Choosing the right trade type is a key part of any good plan.

Morning vs Afternoon Expiration

Normal monthly SPX trades expire on the third Friday of each month and use AM rules. Trading for these deals ends on Thursday afternoon. This means you cannot trade them on the Friday they end. If you hold a trade overnight from Thursday to Friday, you face market moves that happen while the exchange is closed. You can learn more about how SPX options settlement works to better prepare for these moves. This gap in trading time makes normal monthly trades a different tool than the more active weekly ones.

PM-settled trades include weekly and 0DTE (zero days to end) contracts. These allow you to trade right up until the market closes at 4:00 PM ET on the day they end. Since they settle at the close, you do not face the same overnight risk as the monthly trades. Most teammates prefer PM rules for short trades because they give more control over the final exit price. They allow for quick changes based on how the index moves as the clock runs down.

The Special Opening Quotation (SOQ)

The settlement price for AM trades is not the index price you see on your screen Friday morning. Instead, the exchange uses a Special Opening Quotation (SOQ). The SOQ is figured using the first trade price of every single stock in the S&P 500 index on Friday morning. If some stocks take longer to open, the final SOQ price might not be known for an hour. This can lead to a price that is much higher or lower than the previous day’s close.

This process can result in a price that is different from the Thursday close or the Friday opening index level. For PM trades, the process is simpler. They settle based on the official closing price of the index at 4:00 PM ET. Knowing these key differences between SPX and SPY is vital for anyone who trades broad markets. The simple PM rules are one reason why 0DTE trading is now so popular.

Managing Overnight Gap Risk

The biggest risk with AM rules is the “overnight gap.” Since trading stops on Thursday but settlement happens Friday morning. News after the bell can move the price against you. You cannot close your trade to stop a loss during this time. This is why normal monthly trades need a firm way to control risk before the Thursday close. Teammates must choose whether to close their trades or accept the risk of a morning surprise.

Always check the trade details before you enter a deal. Some index products have different rules for quarterly or end-of-month dates. Knowing the exact time trading stops helps you avoid being stuck in a trade you did not want. PM trades offer a cleaner exit for day traders, but AM trades remain the standard for many large bank hedges. Each type has a place in a balanced mix, provided the trader knows the rules of the game.

Criteria	AM-Settled (Standard)	PM-Settled (Weekly/Daily)
Last Trading Day	Thursday before expiration	Expiration day (Friday)
Trading Stop Time	4:00 PM ET Thursday	4:00 PM ET Friday
Settlement Price	Friday Opening (SOQ)	Friday Closing Price
Overnight Risk	High (Thursday to Friday)	None (Intraday)

How does SPX options settlement work?

When you trade SPX options, you need to know what happens as the clock runs down. These contracts use cash settlement. This means you do not deal with shares when a trade ends. Most stock options force you to buy or sell stock if they end in the money. But with SPX, your broker simply adds or subtracts cash from your account. This setup makes the process much cleaner for teammates in our trading room who want to focus on index price moves without the mess of share delivery.

The role of cash settlement

Cash settlement is a key feature of the S&P 500 index market. As the Cboe notes, positions settle directly to cash at expiration. This removes the risk of “pinning” or having to manage large blocks of stock. It is one of the key differences between SPX and SPY that traders should learn. Since there are no shares, you never have to worry about a surprise stock position appearing in your account after the market shuts.

AM vs PM settlement times

Timing is key when you ask when do SPX options expire and settle. Standard monthly options use AM settlement. Their final price is set on Friday morning based on the opening prices of all 500 stocks in the index. Weekly and daily (0DTE) contracts use PM settlement. These settle based on the market closing price of the S&P 500 at 4:00 PM ET on the day they expire. Knowing which type you hold helps you plan your exit and avoid holding a trade through a price gap.

When the cash appears

Once the final settlement price is set, your broker does the math. For PM-settled trades, the cash usually shows up in your account by the next business morning. If your option ends in the money, the cash gain is yours to keep. If it ends out of the money, it simply expires worth zero. Understanding how SPX options settlement works is vital for good risk management. This clear cycle lets you trade right up until the final bell without the stress of share assignment.

What should traders check before expiration?

Trading SPX options needs a clear plan. You must know the rules before you start. Many people ask, when do spx options expire? The answer depends on the type of trade you hold. Some trades end in the morning. Others end in the afternoon. You need to know which one you have to avoid a big surprise. Missing a day can lead to losses you did not expect.

Check the name and date

First, check the root name and the end date. SPX options are index options. They give you a way to track 500 top U.S. firms. These options help you track the whole market. You must be sure you have the right date on your screen. Sometimes, a trader might pick the wrong week by mistake. This can change how the trade acts. Check your screen twice before you click buy or sell. It only takes a second to be sure.

You should also look at the symbol. SPX options use a Euro-style rule. This means they can only be used on the end date. This helps you avoid the risk of a surprise trade. It gives you more say in your plan. You do not have to worry about a sudden change in your trade. This is one reason why many traders like using index options for their daily work.

Confirm the time and pay

Next, check if your trade is AM or PM settled. Most monthly SPX options expire on the third Friday of the month. This rule helps the market stay steady. The SEC has rules that keep these times fair for all. AM trades use the first price of the day. This can be hard if the market jumps at the start. You need to know how this works before you trade.

PM trades are different. They include weekly and daily trades. These end at the close of the market. This is usually 4:00 PM ET. This gives you time to see how the market moves all day. You can make a choice based on a full day of price data. Knowing the gap between AM and PM trades is key for how SPX options settlement works. It helps you track your risk with more skill and less stress.

1. Find the name. Look at the root and the date. Make sure they match your plan.
2. Check the pay. See if it is AM or PM. This tells you when the trade ends. AM trades use morning prices. PM trades use night prices.
3. Know the last trade time. For most daily SPX trades, this is 4:00 PM ET. If you wait too long, you cannot close your trade.
4. Learn the price. This is how your cash pay is found. SPX trades pay cash. You do not have to handle shares of stock.
5. Set your risk. Know how much you can lose before you trade. Set your stop-loss and stick to it with focus.
6. Check your broker. Look at your screen to see if all facts are correct. Some brokers show data in odd ways, so be sure you know yours.

Using a checklist helps you stay calm. It stops you from making quick, bad choices. Teammates at SPXGODFATHER use these steps to trade with a plan. This helps you build good habits. When you follow a system, you can trade with peace of mind. You are not just guessing. You are following a path that you have tested.

Good traders are also ready for changes. Having a checklist means you are ready for any move. You have already thought about what to do if the price goes up or down. This takes the worry out of the day. It helps you focus on the price and the charts. You can act with speed when the time is right. This is how you master SPX options with a clear mind.

Why expiration details matter for 0DTE traders

Trading zero days to expiration (0DTE) options needs a deep focus on time. For SPX traders, knowing when do spx options expire is more than just a date on a page. It is the heart of how you control risk and keep your cash safe. On the last day, the market moves fast. Small shifts can have a big effect on your trade. You must stay sharp to every change in price.

Gamma and time decay risks

When an option is close to its end, two forces get very strong. These are gamma and theta. Gamma shows how much an option price moves when the index moves. In 0DTE trades, gamma is at its highest point. This means a tiny move in the S&P 500 can lead to a huge swing in your trade value. This can bring fast wins, but it also brings high risk that can wipe out a small account. You need to know how to size your trades to handle these swings.

Time decay, or theta, is the other main force. Options lose value as time goes by. On the last day, this loss happens by the minute. If the market does not move, your option price will fall. This is why 0DTE work is so hard. You are fighting against the clock from the start. We often teach managing zero DTE options risk in our live room to help teammates stay ready. Knowing these forces helps you make better choices in a rush.

Settle rules and timing

Knowing the clock is a must for SPX traders. Most 0DTE and weekly contracts use PM settlement. This means they expire based on the closing price at 4:00 PM ET. But standard monthly options use AM settlement. Their value comes from the Friday morning opening prices. A mix-up here can lead to loss if you do not track the right time. For example, monthly options stop trading on Thursday afternoon, not Friday. This is a trap for those who do not read the fine print.

Trading for these options usually stops at 4:00 PM ET on the day they expire. You cannot trade them after the bell on most exchanges. Since these positions settle to cash at the end, you do not have to buy or sell shares. This is a great perk of SPX over stocks or funds. You avoid the risk of owning a stock you do not want over the weekend. This cash settle process is clean and simple for the active trader.

Firm risk control

Broker rules are another risk. Your broker may have a cutoff for when you must close a trade. If you hold a trade too long, they might shut it down for you. This could happen at a price you do not want. They do this to protect themselves from risk, but it can hurt your profit. To avoid this, you need a clear plan and a steady system. You should know your broker’s rules as well as you know the market.

Top traders do not leave things to chance. They know where to exit before they get in. They watch the gap between buy and sell prices. This gap can get wide as the day ends. It can eat into your gains if you are not careful. By staying sharp and following a system, you can handle the fast pace of 0DTE work. This firm grit is what sets the best traders apart from the rest.

Options trading has big risk and is not for everyone. Past results do not mean you will win in the future. There is no promise of gains or a set win rate. This text is for education only. It is not financial advice or a promise of gains. Always trade with care and follow your own rules. Use risk capital only and never trade more than you can afford to lose.
