JPMorgan Chase on Thursday appointed a pair of senior executives to newly created co-president roles — setting up what appears to be a new horse race to succeed chief executive Jamie Dimon.

At the same time, the Wall Street giant announced the retirement of Marianne Lake, who previously had been viewed as a leading candidate to succeed the bank’s legendary CEO.

Doug Petno and Troy Rohrbaugh, who have jointly run the bank’s Commercial & Investment Bank since early 2024, were named co-presidents of JPMorgan effective immediately, according to a regulatory filing.

Petno will now serve as sole CEO of the Commercial & Investment Bank.

Rohrbaugh will take over as CEO of Consumer & Community Banking, succeeding Lake.

The moves are part of the board’s ongoing succession planning to maintain strong leadership at the top of the nation’s largest bank, the company said in the filing.

Lake, who previously served as JPMorgan’s chief financial officer and has held other senior roles across the firm, is stepping down after a long career.

No specific departure date beyond the leadership transition was disclosed.
