Nasdaq is preparing to launch a nearly continuous trading schedule for U.S. equities on December 6, 2026. The plan adds a Night Session running from 9 p.m. to 4 a.m. Eastern Time, five days a week, bringing the overall trading window close to 23 hours.

Under the new structure, trading would operate from 9 p.m. Sunday through 8 p.m. Friday. A one-hour pause between 8 p.m. and 9 p.m. ET each day would allow for processing and the transition to the next trading date. The existing pre-market, regular, and post-market sessions from 4 a.m. to 8 p.m. ET would continue unchanged. The core regular session from 9:30 a.m. to 4 p.m. ET, including the opening and closing crosses, would remain the primary price-setting mechanism.

Regulatory Path and Remaining Steps

The Securities and Exchange Commission approved Nasdaq’s core proposal for 23-hour trading five days a week in early April 2026. That approval cleared a major regulatory hurdle. However, the December 6 start date still depends on additional SEC sign-offs, readiness of the Securities Information Processor that consolidates market data across exchanges, and finalization of overnight safeguards.

Nasdaq has branded the initiative “Always-On.” Chair and CEO Adena Friedman previously stated that the exchange is leading the shift to a new operating model and expects consolidated tape and market data to support a more transparent environment across the extended hours.

New protections for the overnight window include static price bands designed to automatically reject orders outside specified limits, generally set at 20 percent around a reference price. Certain order types, including unpriced market orders and some pegged orders, will not be available during the Night Session. Members will need dedicated order-entry ports for the overnight period. Any orders remaining open at 4 a.m. or 8 p.m. will be canceled.

Competition With Continuous Markets

Currently, only about 2 percent of Nasdaq volume occurs outside the standard extended hours. Derivatives markets have already moved further ahead. CME Group offers roughly 23-hour trading in single-stock futures on dozens of major U.S. names, alongside continuous bitcoin and ether contracts.

The New York Stock Exchange has explored its own 24-hour model. Private platforms such as Robinhood and Interactive Brokers have offered extended or near-continuous access for selected equities through alternative trading systems for several years. Nasdaq’s move responds to rising global demand for U.S. stocks and investor expectations shaped by markets that never fully close.

ETF specialist Nate Geraci noted the broader industry shift: “Whether you like it or not, TradFi exchanges are now playing by crypto’s rules.”

Operational Details and Market Effects

Liquidity is expected to be thinner overnight. Research cited by the exchange found effective spreads on retail overnight orders roughly three times regular-session levels and price impact about six times larger. Listed companies have been advised to prepare for higher volatility, compressed corporate-action windows, and the possibility of material news reaching markets during the extended hours.

Texas and PSX equity exchanges, along with Nasdaq’s options markets, will not join the overnight schedule and will retain their current hours. Industry testing of the extended Securities Information Processor is scheduled to begin in October, ahead of the targeted production launch.

The change will create longer overlap with trading sessions in other time zones, including India’s National Stock Exchange. During Indian market hours, U.S. stocks could continue to reprice through much of the local trading day, providing more continuous signals for Nifty options, U.S.-exposed Indian equities, and related risk assessments. Access for Indian residents would still be subject to domestic foreign-exchange rules, including the Liberalized Remittance Scheme limit of $250,000 per financial year.

Nasdaq has emphasized that the overnight session expands access without replacing the authoritative role of the regular daytime session. The December 6 date remains contingent on the final regulatory and technical conditions being met.
