A post by @FirstSquawk on X.

Nasdaq Trading Services said it is investigating problems with its email system, according to a First Squawk post on X. The disclosure covers only the email system, with no indication yet that trading, market data or other Nasdaq operations are affected. The notice gave no details on the cause, scope or timing of a fix. The event matters because email underpins order confirmations, trade notifications and client communications for a major exchange operator. What to watch next is whether Nasdaq confirms the issue is contained to email or reports spillover into trading and settlement services.
