Africa’s richest man is preparing to rewrite the continent’s capital markets playbook. Aliko Dangote’s $20 billion petroleum refinery in Lagos has formally filed its prospectus with Nigeria’s Securities and Exchange Commission, clearing the path for what is widely expected to become the largest initial public offering in African history.
The 650,000-barrel-per-day facility, already the biggest single-train refinery on the continent, reached full capacity earlier this year. It has transformed Nigeria from a net importer of refined fuels into a significant exporter, particularly of aviation fuel. Now Dangote aims to more than double capacity to 1.4 million barrels per day by 2028, positioning the plant among the world’s largest.
The IPO, targeted for September 2026, would sell roughly 10 percent of the equity. Advisers include Stanbic IBTC Capital for international book-building, Vetiva for retail distribution in Nigeria, and FirstCap for institutional placements. Pre-IPO interest has already exceeded $2 billion. Just weeks earlier, the company closed a $2.5 billion private placement that was 3.7 times oversubscribed, valuing the business near $40 billion. Participants included the Africa Finance Corporation and vehicles linked to the African Export-Import Bank.
SEC Director-General Emomotimi Agama has publicly stated that the regulator sees no obstacles to the timeline. “If any issue arises, SEC will resolve it,” he told reporters. The listing is expected to deepen Nigeria’s equity market dramatically, potentially ranking among the largest companies by market capitalisation on the Nigerian Exchange and attracting both local pension funds and global capital.The timing is strategic.
Global energy markets remain unsettled by Middle East tensions, and Africa continues to rely heavily on imported refined products. Dangote has repeatedly framed the expansion as a step toward continental self-sufficiency. “This is about reducing Africa’s dependence on imported fuels,” he said during a recent site visit.
Challenges remain. Earlier marketing of an unauthorised offer prompted a sharp SEC warning in June. The company has insisted any formal offering will follow proper regulatory channels. Liquidity, governance standards for a newly public industrial giant, and execution risk on the capacity expansion will all face intense scrutiny.
Still, the momentum is unmistakable. For Nigerian retail investors who have long watched Dangote’s empire from the sidelines, the IPO offers a rare chance to own a stake in a world-scale industrial asset. For the broader African capital markets, it is a stress test of depth and ambition. If successful, it could encourage other large private companies across the continent to follow suit.
The next few months will determine whether the largest IPO in African history becomes a landmark success or a cautionary tale. For now, the market is watching closely.
