For the ultrawealthy, it used to largely be the case that they wanted their flashy home purchases and sales to be made public: Think drone shots, a glossy listing, and a splashy press release naming the owner and buyer.
Key facts
- A February 2025 Zillow Research analysis of 2.7 million home sales also shows that homes sold off the MLS in 2023 and 2024 typically went for almost $5,000 less than those listed on the MLS
- Outside of Silicon Valley, off-market residential sales have surged at least 30% year-over-year in Brooklyn, Manhattan, and Queens between 2024 and 2025, with Brooklyn alone logging roughly $5.4
- Atherton posted a median sale price of $8.33 million in 2025, a 5% gain from the previous year and a new high for the longtime Bay Area billionaire enclave, according to PropertyShark
- In California, the gap widened to 3.7%, or roughly $30,075 per home
Summary
All of that served as a way to show off and solidify their wealth. A growing class of ultrawealthy buyers, particularly tech and AI executives who have moved to Silicon Valley, are deliberately routing their home purchases through limited liability companies, privacy trusts, and so-called “whisper” listings that never touch the multiple listing service. Their end goal isn’t getting the best deal they can possibly get: It’s more about maintaining anonymity and thinning their paper trails to ensure security. The shift started about three years ago, said DeLeon, who is one of Silicon Valley’s top-producing luxury brokers and was once ranked the nation’s No. 1 real estate agent by the Wall Street Journal and RealTrends.
