Mark Zuckerberg has reportedly expanded his sprawling $300 million compound in Hawaii by nearly 1,000 acres — stoking yet more controversy with locals on the idyllic Pacific island chain, according to a report.

The latest expansion on the Meta CEO’s massive estate on the Hawaiian island of Kauai includes 962 acres of ranch land purchased earlier this year under an LLC, according to the tech news site WIRED.

A person close to the sale estimated the purchase price at more than $65 million. The acquisition brings Zuckerberg’s total holdings on Kauai to more than 2,300 acres.
