‘Stealth wealth’ is reshaping luxury real estate: How the ultrarich buy multimillion-dollar mansions off the books

For the ultrawealthy, flashy home purchases and sales were once made very public. Drone shots, glossy listings, and press releases naming the owner and buyer were used to show off and solidify their wealth. However, a new class of buyers, particularly tech and AI executives in Silicon Valley, want to maintain anonymity and thinner paper trails.

This phenomenon is called "stealth wealth" buying. Ken DeLeon, a top-producing luxury broker in Silicon Valley, explained that the shift began about three years ago as the market capitalization of tech companies grew and more wealthy people moved to the area. The desire for privacy has grown even stronger due to increased wealth and AI, which is becoming an increasingly controversial topic.

Home prices in Silicon Valley have continued to rise, with Atherton reaching a new high for its billionaire enclave. Stealth-wealth transactions involve using limited liability companies, privacy trusts, and "whisper" listings that don't go through the multiple listing service. Buyers and sellers often act as a buffer, with agents meeting vendors, signing for inspections, and handling questions to maintain privacy.

While stealth-wealth buyers gain privacy, they pay for it with lower prices, as off-market sales tend to attract less competition and sell for less than fully exposed listings.
