Nasdaq Trading Services is currently investigating technical difficulties affecting its email system. As of November 12, 2026, the company reports that these issues have not resulted in trading halts, market volatility, or any documented impact on its clients.
The organization has not disclosed the specific cause, duration, or nature of the email system disruption. No regulatory notifications have been issued regarding the incident, and there is no evidence linking these problems to broader market instability.
This situation is distinct from a network issue that occurred on October 15, 2026, at the Nasdaq facility in Carteret, New Jersey. That previous event caused intermittent gaps in US equities market data feeds for Nasdaq, Nasdaq Texas, and Nasdaq PSX, requiring the use of backup feeds in Chicago.
Nasdaq clarified that the current email investigation is also unrelated to a separate outage affecting Microsoft Outlook and Exchange Online that occurred on November 12, 2026. Historically, email-related incidents at the firm have been rare, with the last notable event occurring in 2016.
