His vast industrial empire, Dangote Group, dominates cement, sugar, flour, and agriculture, making it one of the most valuable conglomerates on the continent. His net worth has nearly doubled in 2025, fueled by the success of Dangote Cement and the Dangote Refinery, which is transforming Nigeria’s energy sector.
