Zurich is home to 99,300 millionaires (who own assets worth more than 100 million francs) and 12 billionaires, and Geneva to 85,800 millionaires and 15 billionaires, the survey shows. That is a lot of really rich people living in relatively small (on the global scale) cities.

In 2026, the wealthiest individuals in Switzerland are concentrated in three specific areas: the Canton of Zug, the Canton of Schwyz, and the exclusive neighborhoods of Zurich and Geneva. The Canton of Zug is world-renowned for having the lowest corporate and personal income tax rates in the country, attracting billionaires and "crypto-valley" entrepreneurs. Within Schwyz, the lakeside communities of Wollerau and Freienbach are legendary for their high density of millionaires and celebrities. In Zurich, the "Goldcoast" (the sunny northeastern shore of Lake Zurich), including municipalities like Küsnacht and Meilen, is the preferred home for old-money families and international CEOs. Meanwhile, Geneva hosts the ultra-wealthy in the suburb of Cologny, which consistently ranks as one of the most expensive residential areas in the world. Interestingly, while these are the "hubs" of wealth, many of the richest Swiss residents also maintain secondary "chalet" estates in high-altitude resorts like St. Moritz and Gstaad, which offer extreme privacy and world-class luxury far from the city centers.
