The World's Richest Cities

New York is the wealthiest city globally, with 359,500 millionaires and 60 billionaires. The Bay Area of California closely follows, with its millionaire population surging 82% over the past decade.

The U.S. dominates the world's wealthiest cities, home to 11 of the top 50. The surge in tech wealth, stock market gains, and deal-making have created record wealth, especially at the top.
