Dangote Petroleum Refinery and Petrochemicals has formally filed its prospectus with the Securities and Exchange Commission of Nigeria, a development that clears the most consequential regulatory hurdle on the path to what would be the largest initial public offering in African capital markets history, targeting a valuation of between $40 billion and $50 billion and a raise of up to $5 billion through the sale of approximately 10% of the refinery's equity.

The offering is tentatively scheduled for September 2026, with the primary listing on the Nigerian Exchange's Main Board and potential parallel listings on other African exchanges, a structure that would mark the first multi-exchange IPO attempted on African soil.

A consortium of three financial advisers has been appointed to manage the offering: Stanbic IBTC Capital will handle international book-building and foreign portfolio investor engagement; Vetiva Capital Management will manage retail investor distribution within Nigeria; and FirstCap will focus on placements with Nigerian institutional investors, particularly pension funds.

The regulatory filing resolves a key procedural overhang. On June 23, the SEC issued a halt order on all marketing activities related to the IPO after flyers circulated across WhatsApp groups, digital banners promised guaranteed allocations, and stockbrokers collected deposits from eager investors, all without a formal application having been submitted or approved. The prospectus filing now establishes the formal basis on which the regulator can review and ultimately approve the offering.

The scale of the transaction redefines the ambition of African equity markets in a single deal. The previous record on the Nigerian Exchange was MTN Nigeria's 2019 listing at approximately $876 million. The Dangote Refinery IPO is targeting five to six times that figure in a single offer, and nothing comparable has been attempted on any African securities exchange.

NGX Group Chief Executive Officer Temi Popoola described the listing as a landmark moment for the exchange, adding that it would demonstrate Nigeria's capital market can support complex, globally significant transactions and help build a pipeline of high-quality issuers.

Pre-IPO interest has already exceeded $2 billion, drawing attention from retail investors, institutional funds and global capital allocators, a demand signal that was itself part of what triggered the SEC's June marketing halt. The $2.5 billion private placement completed in July, subscribed 3.7 times at an implied valuation of approximately $40 billion, provides the most recent independent pricing reference available to prospective IPO investors.

The refinery, built at a cost exceeding $20 billion and reaching full processing capacity of 650,000 barrels per day in February 2026, already supplies refined products across West and East Africa, and plans to scale to 1.4 million barrels per day by 2030, a target that would position it to supply a significant share of Africa's total refined fuel demand from a single facility.

The filing is not a listing. The SEC must review the prospectus, request clarifications, approve the document and set a subscription window before a single share changes hands publicly. The September timeline implies that the process will be completed in under eight weeks, which is achievable but not guaranteed given the complexity of the transaction and the novelty of a cross-exchange listing structure that Nigerian capital market regulations have not previously had to accommodate at this scale. What the filing does confirm is that the IPO has crossed from ambition into process, and that the question is no longer whether Dangote Refinery will list, but when and at what price the Nigerian public will finally be able to own a piece of it.
