When examining their residences, Gates’ home, Xanadu 2.0, stands out. Located in Medina, Washington, this sprawling 65,000-square-foot mansion is a testament to opulence, featuring advanced technology and a library housing priceless manuscripts. Estimates suggest the mansion’s value has soared to $127 million. In contrast, Zuckerberg’s primary residence is a more modest 5,400-square-foot home in California, which he shares with his family. While he owns multiple properties in the area, including expansive real estate investments worth around $51 million, the simplicity of his main home reflects a more understated aesthetic.
