It’s often said that making money is easy – when you already have some to begin with.
In South Africa, a select group of businessmen has proven this adage true, using generational wealth, bold decisions, and smart investing to amass fortunes that stretch into the billions.
From mining and media to finance and fashion, these seven South African billionaires have built and grown empires that span industries and continents.
Collectively, they hold an astonishing $36.9 billion (R659 billion) in wealth, according to Forbes’ real-time billionaire list.
Compound wealth
South Africa’s wealthiest individuals highlight the power of compound wealth, strategic investing, and often, privileged starting points.
While some leveraged family businesses, others capitalised on market shifts and global opportunities to build their empires.
Though controversial to some, their financial influence is undeniable – not just in South Africa, but on the global stage.
As the saying goes, “the rich get richer.” And in this case, they’re doing so with style, strategy, and staggering numbers.
Meanwhile, in terms of the overall world list, South Africa-born Elon Musk remains the world’s richest person with a reported $410.3 billion.
