Nigerian investment fintech Bamboo facilitated approximately ₦99 billion in subscriptions during the Dangote Refinery IPO, placing it slightly ahead of Zenith Bank and every other identified online distribution platform.

The investment platform also recorded more than 600,000 transactions during the offer, the most of any of the platforms identified in the figures, which were obtained from sources familiar with the transactions.

Zenith Bank followed closely with approximately ₦98 billion in subscriptions, while FirstBank recorded ₦60 billion and investment firm Chapel Hill ₦57 billion. The Nigerian Exchange (NGX) recorded ₦36.4 billion, processing roughly 60,000 transactions. Bamboo's total subscription value came in slightly above Zenith Bank's, despite the lender's established position in Nigeria's financial services industry.

The outcome puts a fintech platform ahead of some of Nigeria's biggest financial institutions in attracting subscriptions to one of the country's most closely watched investment offerings. The figures also highlight the growing role of digital investment platforms in connecting retail investors to opportunities in Nigeria's capital market.

The Dangote Refinery offer served as a major test of that distribution capacity. The refinery, widely described as the largest single-train refinery in the world and the flagship project of Dangote Group — the conglomerate founded by Africa's richest man, Aliko Dangote — stands as one of the most prominent industrial ventures on the continent. In September, the refinery approved 32 subscription channels, comprising 19 commercial banks, 10 fintech and investment platforms, two mobile money operators, and NGX Invest, the exchange's digital subscription platform. The offer closed on October 27, with Dangote Refinery announcing that it was fully subscribed. The company offered 4.1 billion ordinary shares at ₦525 each, targeting approximately ₦2.15 trillion.

According to a report by Nairametrics, the IPO generated more than ₦860 billion in online retail subscriptions from approximately 1.55 million unique subscribers. About 2.2 million online subscription transactions were recorded during the offer, with Bamboo accounting for more than 600,000 of them.

It is important to distinguish between transactions and subscribers. The 600,000 figure represents transactions processed through Bamboo, not necessarily 600,000 different investors, as a single investor may submit more than one subscription.

Bamboo helps Nigerians invest in both local and international opportunities, such as U.S. stocks. By joining the Dangote Refinery IPO as a distribution channel, it stood alongside banks, investment firms, and the NGX as a route through which investors could apply for shares. That marks a shift from the past, when traditional financial institutions were the main gateway through which people accessed investment products and connected to the capital market. Digital platforms are increasingly competing for that role by making investment products accessible through mobile applications.

The figures provide a glimpse into how investors used different digital channels to participate in the offer. However, they cover identified online distribution platforms only and should not be treated as a complete ranking of every bank, fintech, or offline subscription channel.

Nor do the reported numbers establish that fintech platforms have displaced banks as the dominant route to investing. They do, however, show that a digital investment platform can compete with major financial institutions when millions of Nigerians are given an opportunity to participate in a large public offer.

The eventual collation of offline subscriptions will provide a fuller picture of retail participation in the IPO.
