Jamie Dimon became CEO of JPMorgan Chase in 2005. Since then, it has grown into the largest bank in the world, with a market cap of over $495 billion and nearly $4 trillion in assets. But at age 67, questions are beginning to arise about when Dimon will call it quits, and who will be his successor. While Dimon himself says he has no immediate plans to retire, he has hinted at the possibility of running for public office. And after successfully navigating Chase through crisis after crisis, perhaps 2024 will provide him with the perfect opportunity to go out on top.
