Florida<\/a>\u2019s rise was fueled by hedge funders, private equity titans and corporate transplants, a wave that included billionaires like Ken Griffin, Jeff Bezos and Carl Icahn, all of whom helped push Miami-Dade home prices into record territory.<\/p>\nMiami\u2019s Fisher Island (ZIP 33109) has lost its two-year reign as America\u2019s most expensive ZIP code to Atherton, California (94027).Venu\/Adobe StockAtherton\u2019s median home price hit nearly $10 million in the first half of 2026, up about 20% from a year earlier.Getty Images<\/p>\n
Atherton\u2019s comeback tells a different story, one written by AI executives and engineers suddenly sitting on enormous stock windfalls.<\/p>\n
Tucked about 18 miles northwest of San Jose in San Mateo County, Atherton reclaimed its old crown after median home prices there shot up to nearly $10 million in the first half of 2026, a roughly 20% jump from the year before, per PropertyShark\u2019s annual ZIP code rankings.<\/p>\n
The shift reflects changing sources of American wealth: South Florida\u2019s luxury market was built on hedge fund managers, private equity executives, and billionaires like Ken Griffin (pictured), Jeff Bezos, and Carl Icahn relocating during the pandemic era.Aaron Schwartz\/Bloomberg via Getty ImagesAtherton\u2019s resurgence is fueled by AI wealth, with employees of companies like OpenAI, Anthropic (pictured), and SpaceX cashing in stock windfalls for trophy estates.Jason Henry\/Bloomberg via Getty Images<\/p>\n
The town counts venture capitalist Marc Andreessen, WhatsApp co-founder Jan Koum and Golden State Warriors sharpshooter Stephen Curry among its residents, and it\u2019s become ground zero for AI-fueled wealth creation.<\/p>\n
Bloomberg reported Atherton has already logged five home sales north of $30 million this year, putting it on pace to match last year\u2019s tally, as workers from OpenAI, Anthropic and SpaceX cash out stock and pour the winnings into sprawling estates.<\/p>\n

The reshuffling at the top is the latest sign that the geography of extreme American wealth keeps shifting. Fisher Island first grabbed the No. 1 spot during the pandemic-era exodus, when droves of wealthy executives and investors fled high-tax states for South Florida\u2019s shores.<\/p>\n
Slipping to second place is hardly a demotion for Fisher Island. The 216-acre private landmass, reachable only by ferry, yacht or helicopter, remains one of the wealthiest residential ZIP codes in America. Condos there routinely fetch tens of millions of dollars, and residents get private beaches, a golf course, marinas and a country club most Americans will never set foot in.<\/p>\n
The island is dotted with mansions, too, some listed for as much as $85 million. Just last year, Robb Report crowned Fisher Island the nation\u2019s most expensive ZIP code, pegging its median home price at roughly $12 million.<\/p>\n
South Florida isn\u2019t ceding ground in the ultra-luxury market either. Bloomberg found that seven of the 11 residential sales that topped $100 million nationwide last year happened in Florida.<\/p>\n
