It’s often said that making money is easy – once you already have some.
In South Africa, a handful of influential businessmen have taken this notion to new heights, transforming family fortunes, bold moves, and savvy investments into global business empires worth billions.
According to Forbes’ real-time billionaire tracker, seven South African billionaires now collectively command a staggering $36 billion (R647 billion) in net worth, cementing their place in the upper echelons of global wealth.
From mining to media, retail to finance, their stories – though diverse – share common themes: strategic vision, intergenerational capital, and a keen sense of timing.
Legacy Meets Strategy
While some billionaires inherited strong foundations, others built their empires from smart bets and timely pivots.
Their journeys underscore the power of compound wealth – growing riches over time through reinvestment and diversification.
While some figures remain controversial, particularly due to the stark inequalities in South Africa, their influence over business and markets is undeniable.
In a country grappling with rising living costs and high unemployment, the extreme wealth at the top continues to spark conversation.
But it also demonstrates how capital, when carefully managed, can span generations and borders.
Whether admired or critiqued, these men represent the sharp end of South Africa’s financial pyramid – where money not only begets more money, but also power, access, and influence on a global stage.
As the old adage goes: “The rich get richer.”
Meanwhile, in terms of the overall world list, South Africa-born Elon Musk remains the world’s richest person with a reported $398 billion.
Below, the list of the top seven richest South Africans in the world as of 4 August 2025.
