Africa's 22 billionaires saw their combined fortunes surge to a record $105 billion (R1.9 trillion) this year, up from $82.4bn held by 20 individuals last year, the Forbes 2025 Africa billionaires report showed.

He remains Africa’s wealthiest person for the 14th consecutive year. His net worth surged to an estimated $23.9 billion, driven significantly by Forbes now valuing his massive Dangote Refinery near Lagos.
The refinery, operational after lengthy delays, is key to Nigeria's shift from fuel importer to exporter. Dangote, ranked among the world's top 100 richest, calls the project pivotal for Africa's self-sufficiency.
Johann Rupert and family - South African luxury goods magnate Johann Rupert holds firm as Africa's second-richest billionaire. His fortune climbed 39% to $14 billion, largely reflecting the rebound in shares of Richemont, the luxury group he chairs and controls through family holdings.
Richemont, owner of brands like Cartier, benefited from strong global demand for high-end jewellery and watches, cementing the Rupert family's dominant position in the sector.
Nicky Oppenheimer and family - Former diamond heir Nicky Oppenheimer, alongside his family, ranks among Africa's wealthiest with an estimated $9.4 billion. The family sold their historic 40% stake in De Beers to Anglo American over a decade ago for $5.1 billion.
They have since diversified their fortune, notably through the Fireblade Aviation private terminal and significant investments in African renewable energy, venture capital, and conservation initiatives.
