For nearly a decade, the Silicon Valley enclave of Atherton<\/a> reigned as the most expensive<\/a> ZIP code in America. This year, it was dethroned – by a private island off the coast of Miami.<\/p>\n

According to a new report<\/a> from real estate data firm PropertyShark, Miami Beach’s Fisher Island (33109) claimed the nation’s top spot in 2025 with a median sale price of $9.5 million, a 65% jump from last year.<\/p>\n

That bump ended Atherton’s eight-year streak at No. 1, though the San Mateo County community still logged a record $8.33 million median, good for second place nationwide.<\/p>\n

“Price trends were so vertical on Fisher Island this year that the cheapest home sold for $1.41 million, while the most expensive was bought for nearly $23.7 million,” PropertyShark reported.<\/p>\n

Atherton, a small, largely residential town between Menlo Park and Redwood City, is defined by acre-plus lots and zoning that limits most parcels to a single home, keeping supply tight.<\/p>\n

The housing stock skews to gated estates and new-build compounds, aided by a streamlined permitting process. It attracts high-profile buyers – including Warriors star Stephen Curry<\/a>, Netscape co-founder Marc\u00a0Andreessen<\/a>, and other Silicon Valley business executives – who pay for privacy, scale and proximity to Stanford and Sand Hill Road.<\/p>\n

Even with the shake-up at the top, California remains the undisputed capital of luxury housing.<\/p>\n

The state accounted for 61% of the country’s 100 priciest ZIP codes and eight of the top ten, including elite coastal enclaves like Newport Beach, Santa Barbara, Stinson Beach and Los Altos, according to PropertyShark.<\/p>\n

Newport Beach was named the most expensive city overall, with all six of its ZIP codes ranking among the nation’s top 100.<\/p>\n

In the Bay Area, the luxury map is shifting but remains dense.<\/p>\n

The region held 32 of the nation’s most expensive ZIPs, down from its pre-pandemic peak of 55. Stinson Beach in Marin County broke into the top 10 with a median of $5.23 million, marking a 38% year-over-year jump – the strongest gain in the Bay Area this year. Los Altos (94022) joined the elite tier for the first time, hitting $5.1 million.<\/p>\n

San Francisco, however, continues to cool.<\/p>\n

The city now has just one ZIP code on the list – 94123, covering the Marina and Cow Hollow – a steep drop from 13 in 2019.<\/p>\n

PropertyShark’s analysis was based on closed residential sales between Jan. 1 and Sept. 30, 2025, in states where sale prices are publicly disclosed. Year-over-year comparisons rely on 2024 data covering the same nine-month period.<\/p>\n
