Larry Ellison | An Entire Hawaiian Island | $300 Million

Chairman of the Oracle Corporation and Billionaire Lawrence Joseph Ellison probably had problems with booking an all-expense-paid vacation in Hawaii, so he decided to buy an entire island himself or 98 percent of it at least- men gotta do what a man gotta do, right?

The business magnate is the sole owner of Lanai with plans of turning it into a utopia. He owns about 87 thousand acres of land, which is a lot for one man. He aspires to expand even more outside of tourism and completely go green – for much better sustainability. Relatively, he also started a wellness company, Sensei, geared towards helping people have a healthier lifestyle preventing sudden mortality. The company also seeks to capitalize on the island’s agriculture and use it to further their studies a greener and happier Earth.
