Morgan Stanley experienced an accidental data leak on September 23, 2026, when a staffer inadvertently sent an internal document via email. This document contained a list of more than 100 investment-banking deals that the firm is actively pitching and monitoring, primarily across Asia, but also including projects in Europe, the Middle East, and Africa.
The leaked list detailed various prospective deals, including candidates for initial public offerings (IPOs) from countries like China, South Korea, and India. It also identified private equity and pension funds that are backing these companies, and even mentioned some projects that have been put on hold or suspended.
Morgan Stanley acknowledged the incident, stating that client confidentiality is a top priority for the firm. The bank confirmed that it has taken immediate measures to address the accidental information leak and is maintaining communication with all relevant parties impacted by this event. The document was also reportedly uploaded to Instagram.
