Top 10 Africa’s Oldest Billionaires in 2025

When it comes to billionaires we know they are usually much older. These billionaires have built their fortunes over many years in traditional industries like energy, real estate, and manufacturing, which need a lot of experience and strong connections to succeed.

These older billionaires started their businesses when many of Africa’s key industries began. They took big risks and set up major companies that became very important for their countries. 

This situation shows the differences in how wealth is gained and kept, showing how hard it can be for younger generations to reach the same levels of wealth without changes in how wealth is passed down.
