The Nigerian Exchange is about to witness the most consequential listing in its history. Aliko Dangote, Africa’s richest man, has confirmed that the initial public offering of Dangote Petroleum Refinery, the world’s largest single-train refinery, will open its order book on September 14, 2026, with shares priced at N525 apiece. When the dust settles, the transaction is expected to stand as the largest equity market listing ever recorded on the African continent, eclipsing every IPO that has come before it on the NGX, including the MTN Nigeria offering that once held the record.
The Dangote Group plans to float between 5 and 10% of the refinery’s total equity, with roughly 4.1 billion ordinary shares on offer. At the confirmed price of N525 per share, sitting at the midpoint of an indicative N500 to N595 range, the offer is targeting a net capital raise of between $1.55 billion and $1.80 billion. The Securities and Exchange Commission has already approved the public offering, clearing the final regulatory hurdle standing between the refinery and its debut on the Exchange’s main board.
A Listing Years in the Making
The road to this moment has been long. Dangote first signalled his intention to take the refinery public in February 2026, telling investors that Nigerians would be able to buy into the facility within four to five months. What followed was a carefully choreographed sequence of milestones: a prospectus filed with the Securities and Exchange Commission, a nationwide investor roadshow that carried management presentations from Lagos to international financial centres, and a heavily oversubscribed $2.5 billion private placement that gave early institutional backers a taste of the appetite awaiting the public offer. NGX Group also brought together the chief executives of five major African exchanges, including bourses in Johannesburg, Accra, Nairobi and the regional BRVM, to explore cross-border participation in what is being framed as a landmark moment for pan-African capital market integration.
The Dangote refinery, located in the Lekki Free Zone on the outskirts of Lagos, is a 650,000 barrels-per-day facility that reached full nameplate capacity in February 2026 and has since posted test production runs as high as 700,000 barrels per day, cementing its status as the largest single-train refinery on earth. Industry estimates now place the company’s overall valuation somewhere between $40 billion and $50 billion, a figure that would make it comfortably larger than any single company currently listed on the Nigerian Exchange. One particularly novel feature of the offer, still awaiting final sign-off from the Central Bank and the Federal Ministry of Finance, is a proposed dollar-denominated dividend structure that would allow investors buying in naira to eventually receive payouts pegged to the US dollar, a first for the NGX and a detail that has drawn considerable attention from foreign portfolio investors.
Oil and Gas Sector: The Winning Sector So far
The timing of the listing could hardly be more favourable. The NGX Oil and Gas Index has been the standout performer on the Exchange through 2026, and recent trading sessions have only reinforced that momentum, with the sector surging more than 4.5% in a single week on the back of strong gains from Seplat Energy and other major energy names. On a year-to-date basis, the sector’s return has climbed above 90%, making it comfortably the best-performing segment of the entire market and setting an unusually strong backdrop against which the refinery’s shares will begin trading. The broader benchmark All-Share Index has itself been on a firm upward trajectory this year, with a year-to-date return above 55%, buoyed further by FTSE Russell’s recent confirmation that Nigeria will be reclassified from Unclassified back to Frontier Market status, a decision that takes effect on September 21, just days after the refinery’s order book is due to open.
That confluence of events, a resurgent energy sector, a market already drawing fresh foreign attention ahead of its frontier market reclassification, and now the arrival of a company of genuinely global scale, has led analysts to describe the Dangote Refinery listing as a watershed moment for Nigerian capital markets. Should the offer proceed as planned and the shares list successfully on the NGX main board, the refinery would immediately become one of the most heavily weighted constituents on the Exchange, giving the oil and gas sector even greater influence over the direction of the benchmark index going forward.
What Next for Investors
Management has been clear that the NGX listing is intended to stand on its own for now, with no foreign cross-listing planned for at least three years. A secondary listing on the London Stock Exchange has been floated as a longer-term ambition, alongside similar plans already under discussion for Dangote Cement, but both remain firmly on the horizon rather than the immediate agenda. For now, all eyes are on September 14, when the order book officially opens and Nigerian retail investors, alongside pension funds and regional African buyers, get their first opportunity to own a direct stake in an asset that has reshaped the country’s energy landscape. Given the scale of anticipated demand, market watchers expect the offer to be significantly oversubscribed, a dynamic that would not only validate the N525 pricing but could also give the broader market, and the oil and gas sector in particular, a fresh source of momentum heading into the final quarter of the year.
