Top 15 Richest Investors in Johannesburg — 2026 JSE Portfolio Ranking

The Johannesburg Stock Exchange (JSE) has had a strong 12-month run, lifting the paper wealth of those who already hold large blocks of listed shares. 

South Africa’s market is deep and liquid, but ownership in many blue chips is still concentrated. When prices rise, founders, controlling families, and long-term blockholders feel it first, because their stakes are big and they do not trade in and out.

This ranking considers only publicly listed equity stakes on the JSE, valued at prices as of early February 2026 and converted to US dollars using the prevailing spot exchange rate. It is not a full rich list. It excludes private businesses, property, cash, and offshore assets.
