Microsoft founder and philanthropist Bill Gates is today worth $127 billion (£91bn), based on the very latest figures from Forbes. However, the Microsoft founder's personal fortune hit $101 billion for a short time in 1999. Adjusted for inflation, this brings his peak net worth up to $144 billion (£104bn).
The CEO of luxury goods conglomerate LMVH, which numbers Louis Vuitton and Moët Hennessy among its portfolio of brands, Arnault saw his fortune plummet in the early days of the COVID-19 pandemic. But it has spectacularly skyrocketed as the demand for luxury goods has returned, particularly from China. His net worth has peaked so far this year at $193.4 billion (£139bn), according to Forbes, and he was briefly the world's richest person.
The Amazon founder became the first person in Forbes' history of tracking the super-rich to be worth $200 billion back in August 2020. He surpassed the milestone again this year as Amazon's stock price rocketed due to demand in the pandemic. His peak net worth hit $204.6 billion (£147bn), before falling back again as he continues to sell his Amazon holding, but some experts tip him to eventually become a trillionaire.
The fearsome Mongol leader conquered a mind-blowing 12 million square miles of land between 1206 and his death in 1227, more than anyone else in history. But while his hordes pillaged their way through huge swathes of Eurasia (the combined continental landmass of Europe and Asia) – territory that is now worth trillions of dollars – Khan didn't actually hoard his spoils, choosing to redistribute the stolen loot and territory among his subjects instead.
