24X National Exchange, the first US-regulated round-the-clock stock exchange, officially launched and started offering trading services today (Wednesday) after a two-week delay.

Round-the-Clock Trading on an Exchange

The exchange now trades US equities from 4 am to 8 pm ET on weekdays. It is offering the services to both institutional and retail investors globally via broker-dealers licensed by the Securities and Exchange Commission (SEC).

24X National Exchange was the first stock exchange approved by the US SEC, allowing it to offer extended weekday trading hours for US equities. It received regulatory approval in November last year.

“Our launch marks a milestone in the evolution of US equities markets towards trading around the clock,” said Dmitri Galinov, the Founder and CEO of 24X National Exchange. “This launch is a transformational moment for global traders looking to access US equity markets at more convenient times.”

The exchange now plans to extend its trading hours further and expects to launch 23/5 trading in the second half of 2026. When those services are introduced, the exchange will offer trading from 8 pm ET on Sunday through 8 pm ET on Friday, with a daily one-hour pause for operational maintenance.

A Trend in the Trading Industry

The demand for round-the-clock trading has reached its peak in recent times. Although brokers like Robinhood, eToro and others allow trading outside market hours, those trades are executed over-the-counter (OTC) and not on any centralised exchanges.

Meanwhile, the top US stock exchanges, including the New York Stock Exchange and Nasdaq, are also exploring the possibility of extending their trading hours. The trend is also emerging in overseas markets, with the London Stock Exchange exploring the idea as well.

Interestingly, the Commodity Futures Trading Commission (CFTC), which regulates the derivatives markets in the US, is also seeking public comments on allowing round-the-clock derivatives trading.

While technology remains a major challenge in keeping markets up and running continuously, 24X National Exchange has built its systems on the infrastructure of MEMX Technologies. The Unlisted Trading Privileges (UTP) data feed exchange code for 24X National Exchange is ‘G’.

“24X National Exchange’s launch is just the beginning – we’re one major step closer to making 23-hour weekday trading a reality for US equities worldwide,” Galinov added.
