Who are the top 32 self made billionaires? - Business Leader News

Who are the top 32 self made billionaires?

With the impending dawn of the first trillionaire expected before 2030, it’s time we asked, who are some of the world’s richest people, where have they come from, and what do they invest in? For our most recent Top 32 list, we’ve looked at the top self-made billionaires.

How have the top 32 been chosen?

We have collated a list of current billionaires who are self-made, as opposed to inheriting the money and growing with it. Some of these individuals come from almost nothing, whereas others came from middle-class backgrounds, ultimately all billionaires in this list have made their fortune from little-to-no funds, creating a true rags-to-riches story.

All net worths have been taken from Forbes ‘Real Time Net Worth’ as of the 8th of March 2023, apart from Lord Alan Sugar and Johnny Boufarhat, where the Sunday Times Rich list was used alongside currency converters.

This list is in no particular order.
