Nasdaq's Planning for Near 24-Hour Trading

General
1

Nasdaq has taken its first official step toward 23-hour, 5-day trading for stocks and ETFs, targeting a rollout in H2 2026.

How It Will Work:

Trading will expand from current 16 hours to 23 hours daily

Two sessions planned:

  • Day session: 4am-8pm ET (includes current pre-market, regular, and post-market)

  • Night session: 9pm-4am ET (next calendar day)

  • One-hour break (8pm-9pm) for maintenance, testing, and trade clearing

  • Trading week runs Sunday 9pm through Friday 8pm

This is reflecting how global investing has truly become 24/7. US markets attract massive global capital (nearly $17 trillion in foreign holdings)

Once it happens:

  • Markets will react on real time
  • International investors will get access when their day starts
  • Faster price discovery, quicker reaction to global events

Also there are opinions that traditional exchanges are also responding to crypto, which already trades 24/7 and has reshaped investor expectations

In many ways, this is about staying competitive. When crypto, forex, and global markets never sleep, equity markets can’t stay confined to legacy time windows forever.

From a long-term perspective, extended trading feels like a natural evolution to me, like some day this was expected.

I still have a question in mind??

@nithin If US markets move closer to 24-hour trading, should Indian markets eventually extend their trading hours too?
Would it help global participation, or there can be liquidity issues?

Curious to hear thoughts from traders, investors, and market professionals here.

One thing to keep in mind is that longer trading hours do not automatically mean better markets. It can break volumes, widen spreads, and push risk to times when the market is less active, so what really matters is market depth and institutional participation, not just staying open longer.

Now they are competing with crypto.

I just think it’s laziness on the part of the exchanges not to have 24hr trading window. That and T+1,T+2 settlement cycle… All settlements can be done instantly in this day and age.

One of the aspects of a 23x5 market would be that it favors organizations and not indviiduals, as an individual in unlikely to be able to remain active (and performant) for extended periods over an entire day.

Alternately, to reliably participate, an individual participant could formalize and automate their trading system to function without their manual intervention for limited/extended periods.

Not sure how dominant of an aspect the above is,
and whether this (and second order effects)…

a. …will lead to further concentration of volumes/profits within select few organizations at the expense of individuals? :thinking:

b. …will increase the cost of participation for individuals, as additional tooling/automation is almost necessary for participation/success?

( Sounds somewhat like the challenges introduced by an exchange enabling/supporting HFT. )
