A lavish estate inspired by Lake Como, located in the San Francisco Bay Area, has been sold for a remarkable $70 million to a buyer involved in the artificial intelligence sector, marking a new peak in the region's tech wealth growth and pushing real estate prices to unprecedented levels.
Situated south of San Francisco, this property represents the highest sale ever recorded in the affluent town of Hillsborough, surpassing the previous record and establishing itself as the most expensive real estate transaction in Northern California this year, as noted by Jennifer Gilson, the listing agent with Golden Gate Sotheby’s International Realty.
While details about the buyer remain under wraps, it has been confirmed that he is a figure within the AI industry. This trend signals a burgeoning housing market in Silicon Valley, largely propelled by the influx of wealth from AI advancements. Recently published research indicated that over 140 homes in San Francisco have sold for at least $1 million above their listed prices within the year’s first half.
The estate, known as "Villa de Verano," was initially offered at $88 million and spent just under five months on the market. Encompassing a sprawling 12 acres, the stunning residence features a six-bedroom, 12,400 square foot main house, complete with a gym, theater, spa, and aquarium. Additionally, the property boasts remarkable outdoor amenities including a swimming pool, a rose garden, an amphitheater, a guest house, and a recreation area equipped with seven courts and a putting green. Its lavishness is particularly striking, even when compared to other grand homes in Hillsborough, such as Bing Crosby’s former $25 million residence, Elon Musk’s $32 million former property, and the $17.8 million Koshland Estate tied to Levi Strauss.
Gilson characterizes this significant sale as merely a "stepping stone" towards an expanding market that caters to the wealthiest buyers. “There’s been a noticeable surge in buyers from the AI sector just in the past year,” she remarked. “We might be on the cusp of a wave of ultra-luxury real estate transactions.”
The real estate landscape is evolving, particularly after San Francisco-based companies OpenAI and Anthropic initiated their initial public offerings earlier this summer, leading to the emergence of a new cohort of multimillionaires entering the property market. An analysis conducted by brokerage Compass indicates that the housing market is becoming increasingly stratified by income levels and proximity to AI job centers.
Gilson has observed a surge in affluent buyers, not only from AI firms but also from more traditional industries, noting a “definite increase” in ultra-wealthy clients seeking out off-market opportunities, where she connects buyers directly with sellers without the homes ever being publicly listed.
In San Mateo County, where this high-profile sale occurred, the median price for single-family homes rose by 8.5% from May 2025 to May 2026. In nearby San Francisco County, the median home price surged more than 20%, climbing from $1.8 million to $2.2 million.
