About This Ranking
The oldest billionaires have accumulated wealth over multiple market cycles, recessions, and structural shifts in the global economy. Many started their companies in the 1950s–1970s and have retained large equity stakes over decades of compounding. Their longevity — both personal and financial — offers lessons in how great businesses can endure across generations.
