South Africa’s billionaires: How seven moguls built massive fortunes
People often say the first million is the hardest to earn, but for South Africa’s wealthiest, the real test is managing billions.

They say earning the first million is the hardest, but for South Africa’s wealthiest, the real challenge is managing billions.
Forbes’ real-time billionaire tracker shows that seven South African billionaires now control a combined net worth of $36.4 billion (R646 billion), underscoring the country’s deep wealth gaps and the enduring influence of capital.
From mining magnates to retail tycoons, these business leaders command empires that stretch across continents and industries.
Though their paths differ, some inheriting fortunes, others building them from scratch, they all follow the same formula: long-term strategy, reinvestment, and the power of compounding wealth.
Legacy, Luck, and Leverage
Several of these billionaires began with family wealth or favourable access to capital, allowing them to take bold business risks.
Others seized the moment – pivoting early into emerging sectors like fintech, pharmaceuticals, and global luxury brands.
“This is what intergenerational wealth looks like,” says economist Duma Gqubule.
“They don’t just build businesses – they build ecosystems of wealth that generate returns across decades.”
Controversy in Context
In a country facing one of the world’s highest unemployment rates, extreme inequality, and soaring living costs, many South Africans view the concentration of wealth in a few hands as deeply contentious.
Critics contend that billionaires often build their fortunes on historical advantages — from apartheid-era access to capital and land to modern loopholes in tax systems and corporate governance.
Supporters, however, argue that these billionaires create thousands of jobs, boost exports, and finance major philanthropic projects, helping to fill gaps the state fails to address.
“We can’t ignore inequality, but we also can’t ignore the strategic discipline that’s required to grow and sustain wealth,” says investment analyst Thandeka Sibanda.
The Power of Capital
Whether people praise their acumen or criticise their privilege, South Africa’s billionaires prove a consistent truth: when managed well, money multiplies — often across generations and borders.
They occupy the sharp apex of the country’s economic pyramid, where capital not only accumulates but also amplifies, generating both returns and global influence.
As the old saying goes: “The rich get richer.”
But as South Africa debates how to close its gaping wealth divide, that saying may be less of an observation – and more of a challenge.
Meanwhile, in terms of the overall world list, South Africa-born Elon Musk remains the world’s richest person with a reported $413.2 billion.
Below, the list of the top seven richest South Africans in the world as of 11 August 2025.
