America’s Most Expensive ZIP Code Just Hit $10.7 Million. Here’s Where Luxury Home Prices Are Soaring

October 22, 2026

Think home prices are high in your neighborhood? Try $10.7 million.

That’s the median sale price in Atherton, Calif. The Silicon Valley enclave just became the first ZIP code in America to break the eight-figure mark, according to PropertyShark’s annual ranking.

For perspective, that sum could buy roughly 29 homes at the typical U.S. home value of $366,913, according to Zillow’s September 2026 housing market report.

And Atherton isn’t the only place where luxury home prices are soaring. The Hamptons are closing in, New York is challenging California’s dominance, and in some ZIP codes, even $2 million isn't enough to make the list.

Atherton is back on top as the most expensive ZIP code in America

Atherton’s 94027 ZIP code reclaimed first place after losing its crown to Florida’s Fisher Island last year.

The northern California community, known for its sprawling estates and proximity to major technology employers, saw its median sale price jump 29% from a year earlier, according to PropertyShark.

“We knew from past years’ price trends that breaking the $10 million mark was inevitable and coming soon,” said Eliza Theiss, author of PropertyShark’s report.

But what surprised Theiss more was the growing competition from the East Coast.

“New York tying the Bay Area was more unexpected,” she said.

The Hamptons are giving Silicon Valley a run for its money

If Atherton is the king of expensive ZIP codes, Sagaponack, N.Y., isn’t exactly living on a shoestring budget.

The Hamptons hot spot climbed to second place with a $7.35 million median sale price, according to PropertyShark. That was up 24% from a year earlier.

Fisher Island, the exclusive island community off Miami Beach that topped last year’s ranking, slipped to third place at $7.22 million, a decline of roughly $2.3 million.

Bridgehampton, another Hamptons community, posted an even more dramatic increase. Its median sale price more than doubled, soaring 114% to $6.15 million.

New York catches up to California with eye-popping home prices

For years, the San Francisco Bay Area dominated the nation’s most expensive ZIP code rankings.

Not anymore. At least, not by itself.

For the first time, the New York metropolitan region tied the Bay Area, with 31 ZIP codes each among the country’s priciest.

Suffolk County, home to the Hamptons, had a record 10 ZIP codes on the list. Westchester County, just north of New York City, also hit a record, with three.

Meanwhile, some Bay Area ZIP codes slipped out of the top 100 as prices in other luxury markets climbed faster.

“Quite a few formerly top 100 Bay Area ZIPs are hovering just outside the top 100, within a $250,000 band of the entry price,” said Theiss.

California still dominates nationally, accounting for 57% of the priciest ZIP codes. But that’s its smallest share since PropertyShark began tracking the rankings, down from a pre-pandemic peak of 73%.

California’s Newport Beach has expensive taste in every ZIP code

Some cities have one especially pricey neighborhood. Newport Beach, Calif., apparently decided that wasn’t enough.

All six of the city’s ZIP codes made the top 100 most expensive to buy a home in. That made Newport Beach the nation’s priciest city by PropertyShark’s measure.

San Diego County is gaining ground, too, with six ZIP codes on the list compared with three in 2016.

And on the East Coast, Cape May County, on the shore, helped push New Jersey’s total to seven ZIP codes. That’s another sign that the luxury market’s geography is expanding.

Even the cheapest ZIP code on the list isn’t cheap

Perhaps the most revealing number in PropertyShark’s report isn’t Atherton’s $10.7 million.

It’s $2.22 million.

That’s the minimum median sale price needed to qualify for this year’s top 100, up 9% from last year and a 69% increase from 2016.

A decade ago, that price would have ranked 24th nationally. Today, it barely makes the cut.

“The overall price growth is real and sustained and visible even at the bottom of the ranking,” said Theiss.

About 70% of the ZIP codes on this year’s list recorded year-over-year price increases. Nine surpassed $5 million, while 52 reached at least $3 million.

Only five ZIP codes were new to the ranking, which included 122 ZIP codes because of ties.

How do homebuyers finance multimillion-dollar homes?

Not every homebuyer purchasing a multimillion-dollar property is paying entirely in cash.

Some use jumbo loans. These are much larger mortgages for pricier properties that exceed the conforming loan limits established by the Federal Housing Finance Agency.

Jumbo loans allow qualified homebuyers to finance expensive properties without paying the entire purchase price upfront. They generally require strong credit, sufficient income, and substantial financial reserves. Down payment requirements vary by lender and loan amount.
