Rich List
The Richest Billionaires in the World (2026): Ranked by Net Worth
The richest billionaire is Elon Musk, worth an estimated $1.2 trillion in 2026, which makes him the world’s first trillionaire and the top name on the global wealth rankings. His fortune comes mainly from SpaceX, which went public in June 2026, alongside his stake in Tesla. The ranking below sorts every billionaire we track by current net worth.
Big fortunes at this level almost always come from owning large slices of successful companies rather than from a paycheck, so the value rises and falls with each firm’s share price. That is why the leaders cluster in technology, luxury goods, retail, and energy. Every name in the table links to a full profile and biography with the numbers, backstory, and how the money was made.
