Columbus Day, a federal holiday in the United States, falls on the second Monday of October each year. As investors and traders prepare for the upcoming holiday, a common question arises: Is the US stock market open on Columbus Day 2025? This article delves into this query, providing a comprehensive overview of the stock market's operation on this federal holiday.
Understanding Columbus Day and the Stock Market
Columbus Day commemorates the landing of Christopher Columbus in the Americas in 1492. It is a federal holiday observed on the second Monday of October. However, unlike other federal holidays, Columbus Day does not necessarily disrupt the operation of the stock market.
The US stock market operates under the jurisdiction of the Securities and Exchange Commission (SEC). The SEC determines the market's operation schedule, and it is rare for the market to be closed on federal holidays. Generally, the stock market remains open on Columbus Day, as it does on most federal holidays.
Stock Market Hours on Columbus Day 2025
The US stock market operates under specific hours. On regular trading days, the market opens at 9:30 AM ET and closes at 4:00 PM ET. However, on Columbus Day, the market hours may differ slightly.
Pre-market and Post-market Trading
On Columbus Day, pre-market trading typically begins at 4:00 AM ET and ends at 9:30 AM ET. This allows traders to engage in trading activities before the regular trading session. Similarly, post-market trading usually starts at 4:00 PM ET and ends at 8:00 PM ET, enabling traders to execute trades after the regular trading session.

Impact of Columbus Day on Stock Market Activity
While the stock market remains open on Columbus Day, it is not uncommon for trading volumes to be lower than on regular trading days. This is because many investors and traders take advantage of the holiday to unwind and spend time with family and friends.
Historical Data
Looking at historical data, the stock market has remained open on Columbus Day in previous years. For instance, in 2024, the stock market was open on Columbus Day, and trading volumes were slightly lower than on regular trading days.
Conclusion
In conclusion, the US stock market is expected to remain open on Columbus Day 2025. Traders and investors should be aware of the market's operation schedule and adjust their trading strategies accordingly.
