- 20% price protection bands will be implemented during overnight hours to mitigate volatility in periods of lower liquidity.
Nasdaq is moving toward a near-continuous trading model that narrows the historical gap between traditional stock exchanges and cryptocurrency markets. The SEC approved on April 10, 2026, the amendments under filing SR-NASDAQ-2025-109, formally enabling the expansion of trading hours to 23 hours per day. The production launch is scheduled for December 6, with integration tests planned for October.
The new Night Session will operate from 9 p.m. to 4 a.m., Eastern Time, from Sunday night through Friday night. The existing pre-market, regular market, and post-market sessions will remain unchanged. Between 8 and 9 p.m. there will be a technical pause dedicated to processing and the transition between trading dates. Orders active at the close of each time block will be automatically canceled.
Nasdaq Deepens Its Convergence With the Crypto Model
The extended hours at Nasdaq respond to strong investor demand for access to markets outside conventional trading hours, an expectation that crypto asset markets — operating 24 hours a day, seven days a week — firmly established over the last decade.
However, Nasdaq clarified that the new scheme does not involve the incorporation of blockchain technology or the tokenization of equities under this specific launch. The initiative remains within the regulated infrastructure of the Nasdaq Stock Market, and opening and closing auctions will continue to be tied to regular hours as price references for listed securities.
At the same time, the company’s 2025 annual report mentioned separate initiatives involving tokenized equity within broader modernization plans, which explains why specialized coverage connects the extended hours with the crypto universe.
Risk Controls for the Overnight Session
The Unlisted Trading Privileges Securities Information Processor scheduled the start of its extended hours for December 6, with a price protection structure specific to the overnight segment. An SEC order dated August 5 approved the first phase of those controls, establishing 20% bands around reference prices between 9 p.m. and 4 a.m. Primary listing markets will calculate upper and lower limits before the start of each overnight session, and exchanges will be able to activate regulatory halts if the price formation process deteriorates.
The mechanism is analogous to the Limit Up-Limit Down system that governs the regular session, though without the automatic halts of that scheme. The SEC explained that the objective is to contain extraordinary volatility during periods of lower liquidity — a critical variable when comparing the extended hours with cryptocurrency markets, where continuous access does not guarantee equivalent market depth.
On September 17, the SEC convened a panel in which Chair Paul Atkins will review operational, resilience, and investor protection aspects ahead of the December launch, which will mark the first Sunday overnight trading session for securities listed on Nasdaq under the newly approved framework.
