Larry Ellison

Larry Ellison's wealth used to be an Oracle database story; now it's an AI infrastructure story. The company's cloud partnerships with Microsoft and OpenAI, supplying the data-center capacity the AI boom actually runs on, are what carried his net worth to roughly $170 billion. Off the balance sheet, he owns 98% of the Hawaiian island of Lanai, which remains the detail people bring up about him more than anything Oracle has shipped in years.
