Last December, a lengthy Wired investigation said Meta CEO and Facebook founder Mark Zuckerberg was in the process of building a 1,400-acre compound on the Hawaiian island of Kauai, which would include a underground shelter spanning over 5,000 square feet. That’s more than twice the size of the average private family home in the U.S.

Mark Zuckerberg denied rumours of a “Doomsday bunker” beneath his $270M Kauai estate, calling it a basic shelter like a basement. He emphasized the ranch’s focus on raising high-quality cattle, not building a survival hideaway.

Meta CEO Mark Zuckerberg told Bloomberg a reportedly 4,500-sqaure-foot basement in his Hawaii compound was just a "little shelter."

Zuckerberg is in the process of constructing Koolau Ranch, a 1,400-acre compound that includes two mansions and a dozen buildings.

The underground shelter, which was revealed last year, prompted conspiracy theories on social media about wealthy tech moguls building doomsday bunkers.

Mark Zuckerberg describes his bunker, part of his massive Hawaii property, as "just a little shelter." The compound contains 12 treehouses, two mansions, a 5,000-square-foot bunker and extreme security measures.
