Can Africa finance itself?

Aliko Dangote has built Africa’s biggest refinery. He now wants millions of Africans to buy into it.

Dangote is seeking to raise about $1.6bn through the initial public offering of Dangote Petroleum Refinery and Petrochemicals. The offer, which values the business at about $49bn, is expected to become Africa’s biggest initial public offering.

It opens on September 14 and closes on October 13. About 4.1 billion shares are being offered at N525 each, with a minimum subscription of 10 shares.

By targeting as many as 10 million investors, Dangote is attempting to do something Africa has struggled to do for decades — mobilise its own capital on a sufficiently large scale to finance industrialisation.

If he succeeds in attracting millions of ordinary investors, the IPO could demonstrate that large African businesses can mobilise domestic savings on a scale that has traditionally been associated with international capital.

For years, Dangote Refinery has been identified almost entirely with its founder. His money financed the project, and his name became inseparable from the refinery.

David Bird, the refinery’s CEO, has described the offer as a “people’s IPO”. The minimum subscription of 10 shares is intended to make participation possible for ordinary investors.

Nigeria has millions of savers, pension funds and institutional investors, yet much of that money does not find its way into large domestic businesses that need long-term capital. Companies looking for billions of dollars have often depended on banks, foreign investors, private equity or government-backed financing.

Dangote is testing whether a significant part of that capital can come from within Africa.

The refinery cost about $20bn to build and took more than a decade to complete. It has crude-processing capacity of about 700,000 barrels per day, making it the world’s largest single-train refinery.

Dangote wants to take that to 1.4 million barrels per day by 2029, in an expansion expected to cost about $14.3bn.

The company is also looking at additional petrochemical capacity, storage facilities across Africa and a refinery project in Kenya.

The IPO is intended to provide additional capital for the company’s expansion.

The refinery produces petrol, diesel and aviation fuel. Its wider complex includes fertiliser and petrochemical operations. The fertiliser plant has an annual urea production capacity of about three million tonnes.

For Nigeria, the refinery represents a break from a pattern that has existed for decades. The country exports crude oil but has imported much of the petrol and other refined products it consumes.

Billions of dollars were spent importing products made from Nigerian crude after it was shipped abroad for refining.

Dangote’s refinery processes crude in Nigeria, sells some products at home, and exports the rest.

Reuters has reported shipments of petroleum products from the refinery to countries including Ghana, Togo, Côte d’Ivoire, Cameroon and Tanzania. Ghana has also explored buying more refined products from Dangote rather than relying as heavily on European supplies.

 More refining capacity inside Africa can keep a greater share of the refining, trading and value creation within the continent.

Dangote is producing fertiliser and petrochemicals alongside fuel. Agriculture needs fertiliser. Manufacturing needs petrochemical products. Producing more of those products within Africa can reduce dependence on imports.

At 1.4 million barrels per day, Dangote would have refining capacity far beyond Nigeria’s domestic requirements. Exports would consequently become a central part of the business.

The company has said it plans to build storage facilities across Africa. Its proposed Kenya project would extend the business into East Africa.

A refinery that began as a Nigerian response to fuel imports is becoming a regional business.

The proposed valuation of about $49 billion has already attracted questions.

The refinery made about $1.82bn in after-tax profit in the first half of 2026, compared with a $476m loss for the whole of 2025. Disruptions to global refining and fuel supply have helped the company.

But those conditions may not last. Refining is cyclical. Crude prices change. Demand changes. New refining capacity comes into the market. Shipping costs rise and fall. Geopolitical crises can push profits sharply higher and then disappear.

Dangote will have to show that the refinery can make money through different market conditions, not only during a period of tight global supply.

Crude supply is another factor. A refinery processing hundreds of thousands of barrels a day needs dependable feedstock at an economic price. Nigerian refiners have long complained about problems involving crude availability, pricing and logistics.

The refinery is already operating, exporting and generating profits. Investors are being asked to provide capital for its next stage of expansion.

A successful offer would put a major African industrial company in the hands of a much wider group of people. Ordinary investors would have a financial interest in an asset they have previously known mainly as a symbol of Dangote’s wealth and industrial ambition.

It could encourage other companies to look to the Nigerian Exchange as a source of serious growth capital.

Large African companies would have evidence that domestic investors can support very large offerings. Pension funds and other institutions could have more sizeable African industrial assets in which to invest. Retail investors could become a more important part of capital formation.

The IPO will put Dangote’s valuation and expansion plans before the judgement of the market.

Dangote built the refinery with private capital. He is now turning to public capital from Africa to help build what comes next.

With the refinery, Dangote showed that Africa could build at world scale.

With the IPO, he is testing whether Africa can also finance it.
