And thanks to one of the costliest construction projects in New York history, Dimon, 69, will soon run

America’s biggest bank from a brand new megatower—one that anchors a group of skyscrapers that will create JPMorgan’s own Manhattan neighbourhood. That new home is arguably a symbol of the

oversized role the bank , and its billionaire chief executive , play across global finance. Dimon has long joked that retirement is always a half-decade away, but recently he’s acknowledged that his reign won’t last forever. Given all the potential successors who have come and gone over the years, the question of who it will be has only been getting louder. And it’s not just the finance industry that’s asking. Wall Street’s chiefs hold more sway than they have in decades, so the leader of the biggest United States bank is of great interest both in Washington and around the world.

JPMorgan got even bigger two years ago when it bought First Republic Bank, a purchase that bypassed typical restrictions on such a deal because of an existing exception to the rule for acquisitions of failing lenders.

Indeed, to run JPMorgan means overseeing a bank that is effectively everywhere. Dimon has shown that it can be done.
