Aliko Dangote’s plan to list his giant Nigerian oil refinery is more than a corporate milestone. It is a test of whether African stockmarkets can turn a recent surge in retail enthusiasm into lasting financial depth.

Dangote, Africa’s richest businessman, launched the continent’s largest-ever initial public offering on September 14th. The refinery hopes to raise at least \$1.6bn at a valuation approaching \$50bn. If that valuation holds when trading begins in November, the company will immediately rank among Africa’s most valuable listed firms. Demand has been intense: one popular trading app crashed when the offer opened, and even rural investors can buy shares through point-of-sale terminals.

A wider investing boom

The frenzy reflects a broader change. Africans are increasingly trading shares on their phones, encouraged by fintech platforms, financial advisers and social-media personalities. Nigeria’s benchmark index has risen 71% in dollar terms this year, Ghana’s by 50%, and Zambia’s market has roughly doubled from a year earlier. Apps such as Bamboo now let millions of users across Nigeria, Ghana, Kenya and South Africa buy both local and foreign stocks; its average trade is worth less than \$50.

These markets remain tiny, together accounting for less than 1% of global stockmarket value. Yet they are becoming deeper and somewhat more resilient. They emerged from the pandemic in better shape than many sceptics expected and have so far absorbed the latest Gulf war. Compared with expensive markets elsewhere, African shares also look relatively cheap.

Better domestic policy helps explain the improvement. Ghana and Nigeria have reduced inflation and currency uncertainty. Nigeria has also required banks and pension funds to hold more capital, prompting index provider FTSE Russell to reconsider the country’s demotion from “frontier” to “unclassified” status. Zambia is restructuring its public debt while benefiting from strong demand for copper.

Corporate profits give investors something tangible to buy. MTN Nigeria swung from a loss in 2024 to a record profit of more than \$700m in 2025, while Dangote’s cement business earned nearly as much. In Malawi, rapidly growing bank profits have helped advisers persuade ordinary savers that owning productive companies may protect wealth better than keeping cash under a mattress.

Participation is not the same as stability

More retail investors bring badly needed liquidity, but the features that make these markets exciting also make them dangerous. Spectacular gains attract inexperienced savers; abrupt reversals can punish them hardest. Malawi’s market, for example, fell 20% from its November peak after a bull run, prompting some of the same online voices that had promoted stocks to warn that investing was a “roller-coaster” and a “big boy game”.

Deep, dependable liquidity will ultimately require institutional money, including foreign capital. Listing the refinery in Nigeria rather than abroad may help keep more sophisticated domestic investment at home, although Dangote is considering a secondary American listing in a few years. The current economic upswing may support African markets for some time, but enthusiasm alone cannot guarantee durable growth.

The IPO therefore captures both the promise and the fragility of Africa’s investing boom. Digital access, better policy and profitable local firms are drawing a new generation into public markets. The real measure of success will be whether those markets can convert a stadium-like burst of excitement into patient capital without leaving small savers to absorb the volatility.
