A new analysis by Compass of Bay Area residential sales at $20 million and above underscores the extraordinary strength of Atherton at the very top of the market. Of 81 sales identified throughout the Bay Area from August 2024 through August 2026, 40 were in Atherton, accounting for nearly half of all transactions at this price point.

For the Gullixson Team, the findings are particularly significant. We represented the buyer or seller in 15 of those 40 Atherton transactions, representing 37.5% of all Atherton sales at $20 million and above during the period. See our recent solds here.

Nearly Half of All $20M+ Sales Were in Atherton

The concentration of ultra-luxury sales in Atherton is remarkable. According to the Compass analysis, 49% of all Bay Area transactions at $20 million and above occurred in Atherton, and 73% took place across Peninsula communities. The average sale price among all $20M+ transactions was $29.3 million.

Atherton's 40 sales were followed by San Francisco with 18 and Woodside with 7. Palo Alto and Hillsborough each recorded 4, with the remaining sales spread among Portola Valley, Belvedere, Los Altos Hills, Ross, and Alamo.

These numbers reinforce what we experience every day in our work: Atherton operates as a distinct market within the already exceptional Silicon Valley real estate landscape.

Privacy Plays an Important Role

Perhaps one of the most revealing findings involves how these properties change hands. More than one-third of all $20M+ transactions in the study occurred off MLS. Above $30 million, that share increased to 60%.

At this level, a successful transaction may never begin with a property appearing publicly for sale. Buyers and sellers frequently place a premium on privacy and discretion, making established relationships and direct access particularly important.

Our extensive experience in Atherton has allowed us to build relationships with homeowners, buyers, agents, advisors, and other trusted professionals over many years. Those connections can provide important access to opportunities both on and off the public market.

A New Generation of Wealth Is Shaping the Market

The analysis also provides insight into the people behind today's ultra-luxury purchases. Technology and innovation remain significant sources of wealth, with identifiable buyers connected to companies including Google DeepMind, Windsurf, Codeium, Apple, YouTube, Ahrefs, Verily, and Robinhood.

At the same time, the buyer pool extends well beyond technology. Established private wealth, venture capital, private equity, family offices, and investment firms are all represented.

The result is an increasingly broad and sophisticated buyer base. New wealth created through technology and AI is entering the market alongside generations of established Bay Area wealth, creating new demand for the Peninsula's finest properties.

Experience at the Highest End of the Atherton Market

The ultra-luxury market requires far more than simply bringing a property to market. Pricing, positioning, timing, discretion, and knowing where to find the right buyer can all play critical roles, particularly when so many transactions take place privately.

Our representation in 15 of Atherton's 40 sales at $20 million and above from August 2024 through August 2026 reflects our direct involvement in this highly specialized segment of the market. It also provides us with firsthand knowledge of what buyers are seeking, how properties are being valued, and how transactions at this level are coming together.

Knowing the market is essential. Knowing the buyers within it can be equally important.
