If you're sitting there on a Saturday afternoon checking your portfolio and wondering, is US stock market open tomorrow, the short answer is no. Tomorrow is Sunday, January 18, 2026. The stock market is never open on Sundays.
But wait. There's a bit more to it this week.
Usually, you'd just wait for Monday morning at 9:30 a.m. ET to see those tickers start moving again. Not this time. Monday, January 19, is Martin Luther King Jr. Day. It’s a federal holiday. Because of that, the big players—the New York Stock Exchange (NYSE) and the Nasdaq—are keeping their doors locked tight all through Monday too.
So, if you were planning on executing some trades to start your week, you’ve basically got a long weekend ahead of you.
Why the Market is Staying Closed
It's pretty standard. The US equity markets follow the federal holiday calendar pretty closely, though they don't observe every single one (sorry, Veterans Day). For MLK Day, it’s a full shutdown.

This applies to:
- The New York Stock Exchange (NYSE)
- Nasdaq
- American Stock Exchange (NYSE American)
- Over-the-counter (OTC) markets
Basically, if it involves trading shares of companies like Apple, Nvidia, or that penny stock you're hoping goes to the moon, it’s not happening. The Bond Market is also closed. SIFMA, the group that basically decides when bond traders get a day off, has recommended a full close for US dollar-denominated government securities on Monday.
What About Futures and Crypto?
Now, this is where things get a little "kinda" and "sorta."
If you’re a crypto trader, you already know the drill. Bitcoin doesn't care about Martin Luther King Jr. Day. It doesn't care about Sundays. Crypto markets stay open 24/7/365. You can trade Ethereum at 3:00 a.m. on Sunday night if you really want to.

Futures are a different beast. CME Group (which handles things like S&P 500 futures and Gold) usually has a modified schedule. On Sunday, January 18, futures will likely open at their usual time (around 6:00 p.m. ET), but they will have an early halt on Monday.
Honestly, most retail investors don't need to sweat the futures schedule unless they're deep into day trading. But if you see people on X (formerly Twitter) talking about "the futures are red" on Sunday night, that’s what they’re looking at.
The Regular Weekly Grind
Just so we're clear on the "normal" rules, here is how the timing usually works when it's not a holiday:
The core trading session is 9:30 a.m. to 4:00 p.m. ET. That is the "Goldilocks zone" where liquidity is highest and spreads are tightest.

You also have:
- Pre-Market Trading: Often starts as early as 4:00 a.m. ET for some brokers.
- After-Hours Trading: Runs from 4:00 p.m. to 8:00 p.m. ET.
But again—none of this is happening tomorrow. It's Sunday.
What This Means for Your Monday
Since the market won't reopen until Tuesday, January 20, 2026, at 9:30 a.m. ET, you have a lot of time to digest the news. Sometimes these long weekends can be stressful if there’s a lot of geopolitical noise.
If something big happens over the next 48 hours, the market can't react in real-time. This often leads to a "gap" on Tuesday morning. A gap is just when a stock opens significantly higher or lower than it closed on Friday because the buy/sell orders piled up while the exchange was closed.
Actionable Next Steps for Investors
Don't just stare at a frozen Robinhood or Fidelity screen. Here is what you should actually do with the extra time:
- Check Your Open Orders: If you have "Good 'Til Canceled" (GTC) limit orders sitting out there, remember they won't trigger until Tuesday. If the news changes over the weekend, you might want to cancel or adjust those before Tuesday's opening bell.
- Review Friday's Close: Take a look at how the sectors finished the week. Since the market was closed, you can analyze the "smart money" moves from Friday afternoon without the pressure of live price action.
- Watch Global Markets: On Monday, while the US is closed, look at how the FTSE in London or the Nikkei in Tokyo are performing. They can sometimes give a hint of the global mood heading into the US reopen.
- Organize Your Watchlist: Use the quiet time to prune your watchlist. Get rid of the distractions and focus on the 3–5 stocks you actually want to trade this month.
The market is a marathon, not a sprint. One extra day of rest isn't going to ruin your gains—if anything, it’s a good time to clear your head so you don't make an emotional trade the second the bell rings on Tuesday.
