Oracle co-founder and chairman Larry Ellison has seen his net worth soar to approximately $195 billion, fueled by Oracle's transformation into an AI infrastructure powerhouse, making him $15 billion richer than #5 on this list. Oracle's cloud division has signed multi-billion-dollar contracts with OpenAI, xAI, and major government agencies, pushing its stock to all-time highs in early 2026. At 81, Ellison remains one of the most active tech executives in Silicon Valley, reportedly spending hours each day reviewing engineering decisions.
