How JPMorgan went from 3 female CEO contenders to an all-male succession race

The succession race at JPMorgan has shifted after longtime lieutenant Marianne Lake was informed she is no longer a CEO contender. This change follows the appointment of new top deputies. While the field of potential successors previously included three women, it has now narrowed to two male front-runners. These developments upend the previous trajectory of the leadership transition as the firm determines who will eventually succeed Jamie Dimon as the company's chief executive.
