The combined net worth of Africa’s richest billionaires was projected to be $81.8 billion over the last year, down $3.1 billion from $84.9 billion the year before. Forbes Africa reports that the 3.6% decline comes after a 15% increase the previous year due to rising stock valuations from Zimbabwe to Nigeria.
The number of billionaires rose from 18 to 19, despite the slight fall in the net worth of the continent’s richest people.
Similar to how Dangote kept his title as Africa’s richest man despite a $400 million loss that caused his net worth to fall to $13.5 billion. Johann Rupert, a South African businessman who specializes in luxury items, placed in second place with a net worth of $10.7 billion, down from $11 billion in 2022. Nicky Oppenheimer, a South African with a net worth of $8.4 billion who formerly oversaw the diamond mining company DeBeers, held down the third position.
Christoffel Wiese, a South African who ranks No. 18 and has an estimated net worth of $1.1 billion, is back in this year’s ranking. In 2015, his net worth was $5.7 billion. But, a financial scandal that destroyed Steinhoff’s stock two years ago cost him his billionaire status.
“He sued, and in March 2022, collected 7 billion South African rands (about $400 million) in cash and shares from Steinhoff, totaling about 5% of publicly traded Pepkor,” Forbes reported.
According to Forbes Africa’s methodology justification, the billionaire Mo Ibrahim, who was born in Sudan but now holds British citizenship, was not included. Moreover, “South African Natie Kirsh, who operates out of London, and another billionaire London resident, Egyptian national Mohamed Al-Fayed, were excluded from the platform.”
According to Forbes, “Net worths were determined using stock prices and currency exchange rates as of the close of business on Friday, January 13, 2023. We begin with estimations of revenues or profits and use current price-to-sale or price-to-earnings ratios for comparable public companies to value privately held enterprises. Within weeks or even just days of our measurement date, some list members experience wealth or poverty increases.
Below are the top 10 wealthiest people in Africa
- Aliko Dangote
Aliko Dangote is the richest black guy in the world as well as the richest person in all of Africa. Many business owners will always be motivated by his inspiring account of how he built his company from nothing. Soon after getting his college degree at the age of 21, he borrowed $3,000 from his uncle to import and sell food items in Nigeria.
Within three months following his operations, he was successful and able to repay the debt in full. Nevertheless, Dangote had higher plans than simply making money off of local goods. He had his sights set on becoming a global conglomerate, and as a result, he went on to become one of the greatest African success stories of our time.
Significantly adding to his wealth was Dangote’s 86 percent ownership of Dangote Cement, which is worth $8.64 billion. His $5 billion fertilizer business, which has the capacity to produce up to 2.8 million metric tonnes of urea annually, is another reason contributing to his rising riches.
