Nasdaq Plans Nearly Continuous Trading to Target Asian Market Hours
New York, Monday, 17 August 2026.
Nasdaq is seeking regulatory approval to offer 23-hour weekday trading starting December 6, 2026, aiming to capture Asian daytime volume and strengthen its control over global asset pricing.
Nasdaq Announces 23-Hour Trading Initiative
Nasdaq Inc. (NDAQ) has officially announced plans to engage with financial regulators to expand stock market operations to 23 hours a day, five days a week [1][2]. Under the proposed framework, the exchange intends to launch a new overnight trading session operating from 9:00 PM to 4:00 AM Eastern Time [1][3]. This shift toward near-continuous trading is scheduled to begin on December 6, 2026, reflecting rising global demand from investors seeking to manage risk outside traditional Wall Street hours [1][5]. The initiative aims to allow global investors to execute trades in the U.S. market immediately following significant events, regardless of their time zone [5].
Regulatory Approval and Infrastructure Readiness
While the SEC has approved the rule change for the expansion, final implementation remains contingent on the readiness of market infrastructure, including the Securities Information Processor (SIP) [5][7]. The plan involves expanding trading of NMS stocks and ETPs from 16 to 23 hours a day, representing an increase of 7 hours compared to the standard schedule [3]. However, announced launches in this sector depend on regulatory sign-off and clearing infrastructure readiness, and timelines have slipped before [1]. For context, Cboe Options Exchange recently postponed the launch of extended-hours trading for selected equity options originally scheduled for August 17, 2026 [4].
Strategic Acquisitions to Support Expansion
To advance its push toward always-on global market infrastructure, Nasdaq has entered a definitive agreement to acquire the remaining equity of LeveL Markets [3]. LeveL Markets operates the third-largest alternative trading system in the US, allowing institutional investors to anonymously match and trade large blocks of shares [3]. This acquisition supports Nasdaq’s strategic objective to capture order flow from alternative trading systems and broker internal systems [5]. The move builds on Nasdaq MRX receiving SEC approval on June 26, 2026, for extended sessions covering equity options and specific index options [4].
Global Market Implications and Liquidity
The new night trading schedule will operate from 9 PM to 4 AM Eastern Time, covering 10 AM to 5 PM Beijing Time in December, effectively targeting Asian market daytime hours [5][7]. Analysis of U.S. overnight trading data from January 2025 to June 2025 reveals that overnight trading volume is highly concentrated, with the top 15 assets accounting for roughly 53% to 55% of volume [5]. While the initiative aims to strengthen control over global asset pricing, market mechanics during extended hours may lead to increased financing costs and wider bid-ask spreads due to fewer overnight participants [5][7]. Ultimately, exchanges are competing not just on hours open, but on who defines the next global price [5].
