What happened
On 14 September 2026 Aliko Dangote launched Africa's largest IPO — 4.1bn shares of Dangote Petroleum Refinery at 525 naira each on the Nigerian Exchange — to raise ~$1.6bn and up to ~$2.1bn with greenshoe.
Africa's richest man, Aliko Dangote, has launched the continent's biggest ever share sale. The 67-year-old Nigerian billionaire opened a one-month public offer on 14 September 2026 for a minority stake in his Dangote Petroleum Refinery & Petrochemicals, listing 4.1 billion new shares at 525 naira each on the Nigerian Exchange.
The base offer will raise about 2.15 trillion naira, roughly $1.6 billion, and could stretch to about $2.1 billion if a 30% greenshoe overallotment is fully exercised. That is only around 3% of the refinery, implying a $47-50 billion valuation — more than twice what the plant cost to build — even though Dangote will keep 84-87% and retain majority control. The refinery, which took more than a decade to build and only opened in 2024, can process 650,000 barrels per day, making it the seventh largest in the world.
The deal is being pitched as an IPO for the people. Retail investors can buy as few as 10 shares for 5,250 naira, about $4, and Dangote has told buyers to use only officially listed brokers and treat the investment as long-term money they can set aside for three to five years. Nigeria's Securities and Exchange Commission approved the sale on 4 September, with subscriptions running until 13 October 2026.
Dangote says proceeds will help double refinery capacity and expand the wider complex. With an existing fortune estimated at $28-35 billion, the flotation could add roughly $23 billion to his wealth, lifting him toward $60 billion and cementing his lead as Africa's richest person, but analysts are already questioning whether the lofty valuation can hold without strong throughput and fuel-market margins.

What is confirmed vs what to watch
Confirmed details from BBC, Reuters and Guardian versus the market question on valuation.
- Confirmed: 4.1bn shares at 525 naira, ~3% stake, $1.6bn base / $2.1bn with greenshoe
- Confirmed: 10-share minimum (~$4 / 5,250 naira), 'IPO for the people' positioning
- To watch: $47-50bn valuation is more than twice build cost — filings have not disclosed full earnings guidance
Why it matters for me
Retail investors can own a slice of the 650,000 bpd refinery for 5,250 naira, but a $47-50bn valuation more than twice build cost means the stock must deliver on expansion plans.
Money
Investors · General Public
Nigerians can buy into Africa's biggest refinery for as little as $4, opening a rare direct retail bet on domestic refining.
Work
Investors · Business Executives
A $47-50bn valuation more than twice build cost puts pressure on future earnings; weak throughput or margins could weigh on the share price.
Daily Life
General Public
If IPO funds double refining capacity as promised, Nigeria could cut fuel imports and stabilise domestic petrol supply.

8 claimsNigerian billionaire Aliko Dangote launched Africa's largest-ever share sale on Monday 14 September 2026, selling a minority stake in his Dangote Petroleum Refinery & Petrochemicals on the Nigerian exchange.
The IPO offers 4.1 billion new ordinary shares at 525 naira each, raising about 2.15 trillion naira (~$1.6bn) gross, and up to ~$2.1bn if the 30% greenshoe option is exercised.
The offering represents roughly 3% of the Dangote refinery, which has a 650,000 barrels-per-day capacity (the seventh-largest in the world); Dangote retains majority control after the offer.
The IPO implies a post-offer valuation of roughly $47-50bn for the refinery — more than twice what it cost to build — drawing investor scrutiny over the high valuation.
Retail investors can buy a minimum 10-share bundle for about 5,250 naira (~$4), positioning the deal as 'an IPO for the people.'
The subscription window opens 14 September and runs one month, closing on 13 October 2026; the Nigerian Securities and Exchange Commission approved the IPO on 4 September 2026.
Dangote intends to use the proceeds to help double the refinery's capacity and expand the plant; the refinery took more than a decade to build and opened in 2024.
Dangote, 67, has a net worth of about $28-35bn; the flotation could add roughly $23bn, swelling his fortune to nearly $60bn.
