Aliko Dangote, Africa's richest man, has stated that his true worth may be substantially higher than the figures currently published by global wealth trackers, noting that some of his most valuable firms are privately held.

Dangote made the statements during a street interview with James Dumoulin, the founder of the School of Hard Knocks platform, which is recognized for interviewing some of the world's richest and most powerful people.

When asked about the most money he had made in a single year, Dangote responded: "Well, first quarter, we did about $10 billion."

The Nigerian entrepreneur further contested the net worth valuations disseminated by Forbes and various other wealth indices.

"They say I'm worth $38 billion, but most of our businesses are not listed yet," Dangote said when asked how much he was worth.
