Aliko Dangote, a Nigerian businessman and Africa's wealthiest person, is preparing to sell shares in his refinery business to the public—a process called an initial public offering, or IPO. When he does, his fortune is expected to jump by $23 billion, bringing his total wealth to around $58.2 billion. This would make him wealthier than American hedge fund manager Ken Griffin and tech executive Eric Schmidt.
When companies go public, they sell ownership stakes to investors on the stock market. This move can dramatically increase the founder's personal wealth, even if they keep most of the company for themselves, because the market assigns a much higher value to the business once it's publicly traded. For Dangote, this IPO could cement his position as one of the richest people on the planet.
