South Africa’s richest man, Johann Rupert, has quietly expanded his fortune by more than $1 billion in 2025, solidifying his position as one of Africa’s most powerful industrialists. His financial surge reflects both the strength of his luxury empire and the broader resurgence of Africa’s billionaire class.
According to Bloomberg’s Billionaire Index, Rupert’s net worth has climbed from $13.7 billion at the start of the year to $15.3 billion in April. His ascent up the global rich list has been swift, rising from the 171st position in January to 145th by April. Bloomberg also notes a year-to-date wealth growth of $1.64 billion, including a recent single-day gain of $97.7 million.
Rupert, who chairs the Swiss-based luxury conglomerate Richemont, remains Africa’s second-richest man, trailing only Nigerian industrialist Aliko Dangote. In February, Rupert’s wealth even peaked at $17 billion, briefly making him Africa’s best-performing billionaire of the year. During that time, his year-to-date net worth gain stood at $3.32 billion, far eclipsing Dangote’s $153 million increase.
The secret behind Rupert’s soaring wealth lies in Richemont’s outstanding performance. The group’s fiscal third quarter ending December 31, 2024, recorded record revenues of €6.15 billion -a 10% year-over-year increase at constant and real exchange rates. Sales growth was powered by Richemont’s Jewellery Maisons, including Cartier, Van Cleef & Arpels, Buccellati, and Vhernier, which alone accounted for 71% of total group sales. The jewellery division posted a 14% rise in sales, fueled by strong demand during the festive season.
Rupert’s success story also mirrors a larger trend across the continent. A recent Forbes report highlighted that Africa’s wealthiest individuals saw their collective fortunes swell to $105 billion last year, up from $82.4 billion previously. South Africa led this resurgence, producing seven billionaires, followed by Nigeria and Egypt with four each, while Morocco, Algeria, Tanzania, and Zimbabwe also made significant contributions.
Despite turbulence in global luxury markets, Rupert has steered Richemont with remarkable resilience. His strategic focus on timeless, high-end brands and disciplined market expansion has allowed him to withstand broader economic pressures and continue thriving.
At 73, Rupert’s financial dominance not only reaffirms his place among Africa’s elite but also signals the growing influence of African billionaires on the global stage. His steady, quiet accumulation of wealth paints a picture of a businessman who has mastered the art of navigating shifting global tides while keeping Africa firmly in the luxury conversation.
