Goldman Sachs President David Solomon's promotion to chief executive officer in October sets off a cascade of vacancies, none more important than for his current position.



Solomon, 56, will likely announce his successor — or a pair of them as co-presidents — in September before taking the reins from Lloyd Blankfein, according to people with knowledge of the situation.

Here are the leading candidates:



John Waldron, 49:

Waldron, a star dealmaker who came from Bear Stearns like Solomon, has been given a series of high-profile roles within the investment bank, culminating with his being named co-head of the advisory division in 2014. He joined Goldman in 2000 and has been co-head of the media and entertainment group and a practice catering to private equity firms.
