Larry Ellison

Oracle co-founder and CTO Larry Ellison holds roughly $170 billion, riding the enterprise AI wave as Oracle Cloud Infrastructure emerged as a genuine challenger to AWS and Azure for AI data center workloads. Oracle generates $52 billion in annual revenue and Ellison owns approximately 42% of the company he co-founded in Santa Clara in 1977. His landmark $28 billion acquisition of Cerner in 2022 gave Oracle the largest health IT database on earth, a strategic moat for AI-driven clinical applications that competitors including AWS, Microsoft, and Google are scrambling to replicate.
