Jamie Dimon, CEO of JPMorgan Chase since 2006, credits his financial intuition to his father Theodore, a Wall Street stockbroker who taught him investing through simulation games during his childhood. At age 14 in 1970, Dimon bought his first stock with his father’s guidance before graduating from Tufts and Harvard Business School, then climbing the ranks at American Express, Commercial Credit, and Citigroup before leading JPMorgan Chase. The bank is now the largest in the U.S., with $185.6 billion in revenue in 2025, up $5 billion year-over-year, and a market capitalization approaching $1 trillion. His personal net worth stands at $3.2 billion according to the Bloomberg Billionaire’s Index. Dimon stands out for his exceptional longevity among Wall Street CEOs, having led JPMorgan for nearly two decades, and attributes his philosophy of discipline and consistent effort to his father’s lessons.
