  • Title
    Chairman and CEO
  • Affiliation
    JPMorgan Chase

Dimon is arguably the first person to make the big-bank profit model work, and he hasn’t wavered in his belief in that model even as regulators, academics, and some Wall Street analysts have pressured him to scale back. It’s easy to forget that J.P. Morgan Chase was an also-ran before Dimon showed up (with the 2004 merger between JPM and Dimon’s Bank One). Now it’s the most important bank in the world. Love or hate the ways of Wall Street, it’s hard not to admire its rough-hewn rajah.
