ALIKO DANGOTE is the big man of African business. He is the continent’s wealthiest tycoon , worth give or take $30bn. He has built its largest oil-refining complex, roughly half the size of Manhattan, on the outskirts of Lagos. And on September 14th he launched Africa’s biggest ever initial public offering (IPO) for Dangote Petroleum Refinery, to give the mega-project its official name, hoping to raise $1.6bn at a valuation of nearly $50bn. If it reaches this market capitalisation when its shares begin trading on the Nigerian Exchange in November, it could instantly become one of Africa’s most valuable listed firms.
