Larry Ellison

Oracle co-founder and CTO Larry Ellison holds an estimated $200 billion as of early 2026, riding the enterprise AI wave as Oracle Cloud Infrastructure emerged as a genuine challenger to AWS and Azure for AI data center workloads. Oracle generated $57.4 billion in revenue in fiscal 2025, and Ellison owns approximately 42% of the company he co-founded in Santa Clara in 1977. His $28 billion acquisition of Cerner in 2022 gave Oracle one of the largest health IT databases on Earth, a strategic moat for AI-driven clinical applications that competitors including AWS, Microsoft, and Google are working to replicate.
