Nasdaq’s 23-hour model could change when Indian investors receive U.S. equity signals, rather than simply extending how long American shares remain tradable. The SEC approved the exchange’s core framework on April 10, 2026, paving the way for a new Night Session from 9 p.m. to 4 a.m. ET.
That overnight window will then connect directly with Nasdaq’s existing 4 a.m. to 8 p.m. ET trading schedule, creating an almost continuous market cycle. The transition is targeted for December 6, 2026, although the launch still depends on Securities Information Processor readiness and additional applicable SEC rule changes.
In December, Nasdaq’s 9 p.m. to 4 a.m. ET night session converts to roughly 7:30 a.m. to 2:30 p.m. IST. Since NSE trading begins at 9:15 a.m., the two sessions would overlap directly for about five hours and 15 minutes during winter.
During U.S. daylight saving months, that overlap would narrow to roughly four hours and 15 minutes. However, U.S. trading would not end when the Night Session closes at 4 a.m. ET. Nasdaq’s existing session begins immediately afterward, allowing listed shares to continue repricing through virtually the entire NSE trading day.
As a result, Indian traders would gain a more continuous U.S. market reference while domestic markets remain open. Although they already use GIFT Nifty to track global sentiment, Nasdaq would add live price discovery in individual U.S. stocks, giving investors a more direct intraday view of Wall Street moves.
That continuous pricing window changes when overseas equity information becomes available to Nifty traders. A move in U.S. technology shares during Indian hours can become a same-day reference rather than mainly a next-session cue.
The effect is particularly relevant for Nifty options, where traders continuously price direction, implied volatility, hedging costs, and expectations for the following opening. NSE equity derivatives currently trade until 3:40 p.m. under the Closing Auction Session framework.
Consequently, overseas moves arriving during Indian hours can enter option premiums and hedge adjustments before derivatives trading ends. Yet extended-hours signals carry an important liquidity limitation.
Nasdaq research found effective spreads on retail overnight orders around three times regular-session levels. Moreover, price impact was roughly six times larger, highlighting the thinner liquidity and shallower market depth that can characterize overnight trading.
Indian companies with substantial American revenue exposure would also gain another live external market reference. Infosys generated 56.4% of Q1 FY27 revenue from North America, showing the commercial link between major Indian technology companies and U.S. demand.
Movements in American technology shares or economic expectations can therefore become visible while related Indian stocks remain tradable. The same timing advantage applies to pharmaceuticals and other exporters with significant U.S. revenue exposure.
However, extended trading changes when market information becomes available rather than altering a company’s underlying fundamentals. Earnings, revenue exposure, and business performance would remain the primary drivers of longer-term valuations.
Beyond providing earlier market signals, the new schedule could also make U.S. shares tradable during normal Indian daytime hours when individual brokers support the night session. However, exchange availability would not automatically guarantee access through every platform.
Nasdaq members would need dedicated Night Session ports, while unpriced market orders and several pegged order types would not operate during that window. At the same time, Indian residents would continue to be subject to domestic foreign-exchange rules.
Under RBI’s Liberalized Remittance Scheme, resident individuals can remit up to $250,000 per financial year for permissible current or capital-account transactions. As a result, longer exchange hours could expand potential trading access, while India’s existing funding and remittance requirements would continue to apply separately.
Bitcoin already trades continuously, so the additional U.S. equity session does not give crypto more trading hours. Instead, it creates a more continuous American equity benchmark during the Indian market day.
Consequently, crypto traders can compare Bitcoin moves with live technology-stock pricing when both markets respond to the same macroeconomic or geopolitical information. USD/INR adds another variable for Indians holding U.S. equities.
For instance, a 5% U.S. stock gain can produce a smaller rupee return if the rupee strengthens materially. Conversely, Rupee depreciation can increase the INR-denominated gain. Therefore, Nasdaq’s expanded schedule would narrow the timing gap between U.S. equity price discovery and India’s trading day without replacing regular-session Wall Street pricing.
