Artificial intelligence industry thriving, and the recent boom of large tech companies going public, have created a new wave of wealth in Silicon Valley, driving up the luxury real estate market in the affluent town of Atherton on the Peninsula. So far this year, there have been 5 properties in the area sold for at least $30 million each, with the median residential transaction price approaching $10 million, surpassing Fisher Island in Miami and becoming the most expensive zip code area in the United States once again.
According to Bloomberg, a mansion in Atherton featuring 6 bedrooms, 9 bathrooms, a family theater, a private rose garden, and spa facilities was listed for nearly $32 million this year, and it was sold within 72 hours for a price over $500,000 higher than the listing price.
Data from real estate company PropertyShark shows that in the first half of 2026, the median residential transaction price in Atherton rose by 20% compared to the same period last year, reaching close to $10 million. Local real estate brokers have reported that in the town of Atherton with a population of about 7,000 people, there have been already 5 properties sold for over $30 million this year, nearing the record of 6 for the entire year of 2025.
Luxury real estate brokers in the area have stated that the current market demand is one of the strongest in over 20 years, estimating that there could be over 50 homes sold for at least $10 million this year, creating an atmosphere reminiscent of the dot-com bubble era in 2000.
Atherton has long been a magnet for tech industry leaders, venture capitalists, and billionaires. Figures such as venture capitalist Marc Andreessen, WhatsApp co-founder Jan Koum, Golden State Warriors star Stephen Curry, and Republican gubernatorial candidate Steve Hilton all own residences in the area.
The influx of substantial funds is also transforming the residential landscape in Atherton. Many old houses are being demolished and rebuilt as modern luxury homes featuring glass walls, swimming pools, and high-end smart amenities. Two years ago, a standard single-story residence was sold for $5.7 million, and after being torn down and rebuilt, it was sold for $31 million in April this year. Real estate agents mention that transactions in the $30 million range, once extremely rare, are now gradually becoming the new norm in the market.
With the increase in affluent residents, the demand for private security has also surged. Security firm Global Guardian stated that Atherton has become the postal code with the highest demand for residential security services provided by the company, surpassing even metropolitan areas like New York and Washington. The company has deployed around 60 personnel in the area to monitor clients’ properties round-the-clock, with some luxury homes converting their garages or pool houses into monitoring centers.
Due to security and privacy concerns, more luxury homes are choosing not to list publicly and are completing transactions through limited liability companies to conceal the actual buyers. Data indicates that in 2025, approximately 24% of homes in Atherton were sold through private means, up from 21% the previous year.
The real estate frenzy in Atherton also highlights the increasingly evident “K-shaped economy” in the Bay Area. While the AI boom is generating massive wealth for entrepreneurs, investors, and tech company employees, it also brings along layoffs and worsens housing affordability issues, deepening the wealth gap in the region.
The report points out that with high-valued artificial intelligence companies like OpenAI and Anthropic preparing to go public, and employees selling their stock options in the secondary market to access funds, it is expected that more tech wealth will flow into the luxury housing market in the Bay Area.
