The stock market is going 24 hours, 7 days a week

The Stock Market Moves to 24/7 Trading

The traditional stock market schedule, running from 9:30 a.m. to 4 p.m. and marked by opening and closing bells dating back to the 1870s, is becoming outdated. This shift mirrors the change from physical trading floors to electronic platforms.

Now, Wall Street is rapidly adopting the continuous, always-on trading model seen in cryptocurrency and prediction markets to serve a new generation of retail investors eager for nonstop market activity.

Extended Trading Hours

Market Structural Change

The push for round-the-clock trading is fueled by a surge in retail investor participation, which now accounts for at least 20% of daily U.S. trading volume. There is also a global demand for access to trillions of American equities.

The shift "represents the most fundamental change to market structure since electronic trading replaced the trading floor."
