Cape Town and the Winelands region lead South Africa in billionaire concentration, with six living in these areas, while Johannesburg has only two, according to Henley Partners in its Africa Wealth Report for 2025 .
Despite this, Johannesburg remains Africa's wealthiest city by number of millionaires, with 11 700, compared to Cape Town's 8 500.
Africa now boasts 25 billionaires, 348 centi-millionaires, and 122 500 millionaires - a dramatic shift from the late 20th century, when the continent had only a handful of billionaires and much of its economy was struggling in prolonged decline.
