By Nupur Anand, Niket Nishant, Saeed Azhar (Reuters) -One of the leading contenders to become CEO of JPMorgan Chase, Jennifer Piepszak, on Tuesday took herself out of the running for now, raising the chances of a trio of other executives vying for Wall Street's top job.

JPMorgan Chase & Co. on Tuesday named Jennifer Piepszak its new chief operating officer, but the company’s four major department heads remain more likely successors to Chief Executive Jamie Dimon to head up the largest U.

The largest U.S. bank by assets has elevated Jennifer Piepszak to chief operating officer, in preparation for Daniel Pinto's retirement in 2026. But Piepszak is not interested in being CEO, the company said.
