Elon Musk

The CEO of Tesla, SpaceX, and X reclaimed the top spot and then some in 2026: his net worth reached about $839 billion as of March 2026, per Forbes, by far the largest fortune ever recorded. Tesla generates tens of billions of dollars in annual revenue across electric vehicles, energy storage, and Full Self-Driving software licensing, while SpaceX has become one of the most valuable private companies in the world on the back of Starship development and Starlink satellite internet, which serves millions of customers globally. Musk co-founded PayPal in 1999 and has since built his fortune through compounding equity stakes across multiple transformative industries simultaneously.
