The 5 biggest IPOs ranked by capital raised
This ranking compares reported proceeds, using approximate US-dollar values at the time of each offer. Figures may differ across reports, especially when they distinguish between money targeted and money actually raised. Listings by introduction are excluded because they do not raise new capital.
1. Dangote Petroleum Refinery & Petrochemicals (2026)
The refinery’s reported offer was for 4.1 billion new shares at ₦525 each, targeting about ₦2.15 trillion, or roughly $1.6 billion. Reports also described a greenshoe option that could increase the amount raised. The offer was presented as a “people’s IPO,” with a minimum subscription of 10 shares, and the proceeds were intended to fund expansion. Check the final offer and allotment records before stating how much was actually raised.

2. Airtel Africa (2019)
Airtel Africa listed in London and Nigeria and reportedly raised about $750 million. On the Nigerian Exchange, about 3.76 billion shares were listed at ₦363 each. Their listing added roughly ₦1.36 trillion to the exchange’s market value, giving Nigerian investors access to a large telecoms business operating across Africa.
3. Seplat Petroleum Development Company (2014)
Seplat raised about $500 million by offering roughly 26% of its shares in London and Nigeria. The Nigerian offer price was reported at ₦576 per share. Its listing gave local and international investors a major way to invest in a Nigerian oil and gas producer.
4. Dangote Sugar Refinery (2006/07)
Dangote Sugar offered 3 billion shares at ₦18 each, putting the offer value at ₦54 billion, or about $420–450 million at the time. Reports said demand exceeded the number of shares available, with strong interest from local and foreign investors. It was described at the time as Nigeria’s largest IPO.
5. Transnational Corporation of Nigeria (Transcorp) (2006/07)
Transcorp planned to raise about ₦60 billion by offering 8 billion shares at ₦7.50 each. Reports put the amount actually raised at around ₦22 billion, as the offer was only partly taken up. The deal showed both the ambition of the mid-2000s conglomerate boom and the risk that investors may not buy as many shares as a company hopes.
The reported Refinery offer is much larger than the earlier deals. For fair comparison, state whether each figure is a target, actual proceeds, or an estimate converted into US dollars.
What these landmark IPOs taught investors
1. A famous name does not guarantee a good investment
Dangote Sugar drew strong demand, and the Dangote Refinery offer attracted attention because of its scale and brand. Before investing in any Nigerian IPO, check whether the share price is fair and whether the business can earn enough to support its plans. Understanding valuation metrics such as the price-to-earnings ratio can help you assess whether a company’s share price is reasonable relative to its earnings.
2. A foreign listing brings wider access and wider risks
Airtel Africa and Seplat gave investors access to businesses operating across borders. Their results can be affected by events beyond Nigeria, such as changes in exchange rates, telecoms markets, or global oil prices.
3. A low entry price does not make an investment safe
A small minimum subscription lets more people take part in an IPO, but it does not protect them from losing money. Decide how much you can afford to invest, learn what the company does, and avoid buying only because other people are interested.
4. Money raised is only the beginning
A company may raise funds for expansion, but it still has to use that money well. Look at its plans, its ability to carry them out, and how easily you may be able to sell your shares later.
5. Market conditions can change the result
The mid-2000s IPO boom took place during a period of strong market optimism, but the later market crash hurt many investors. When considering an IPO, look beyond launch-day excitement and assess the economy, the rules affecting the business, and its long-term prospects.

In Nigeria, listing gains vary widely; some mid-2000s and recent industrial listings (including certain Dangote-related and other stocks) showed strong initial moves, but extreme triple-digit first-day pops are rarer on the NGX compared with some international markets.
3. What were the biggest IPOs of the last 5 years?

Other African activity includes smaller listings such as Optasia and Cash Plus (South Africa/Morocco tech/fintech), plus various NGX private placements and rights issues (e.g., insurance and banking recapitalisation-related listings). Exact “today” lists change daily—check the NGX daily official list for the most current.
5. Which IPO is profitable?
Profitability depends on the time horizon and entry price. Long-term holders of quality businesses such as certain Dangote Group companies, Seplat (after its post-2014 recovery), and select telecom or industrial names have seen substantial gains. Many boom-era IPOs from the mid-2000s delivered losses for those who bought near the peak. No IPO is guaranteed profitable; fundamentals, valuation, and holding period matter more than the listing-day pop.
6. What is the largest IPO ever in Nigeria?
The Dangote Petroleum Refinery & Petrochemicals IPO of 2026, targeting ₦2.15 trillion (~$1.6 billion). It significantly exceeds previous Nigerian records such as Airtel Africa (2019) and Seplat (2014).
7. How successful was the subscription for the Dangote Refinery IPO?
It attracted exceptionally strong demand from the first day, with reports of billions of naira in early subscriptions, temporary platform outages, and high retail participation. The offer was structured as a “people’s IPO” with a very low minimum (10 shares / ₦5,250) and saw heavy interest from both retail and institutional investors. Investors looking for application options can consult our guide to all 238 Dangote Refinery IPO application channels.
8. What factors determine whether a Nigerian IPO succeeds for retail investors?
Key factors include realistic valuation, clear use of proceeds, free-float and liquidity, the promoter’s track record, macroeconomic conditions (currency stability, interest rates), and the investor’s own discipline on position size and time horizon. Strong brand names can drive oversubscription, but post-listing performance often depends more on execution and market cycles than on listing-day hype.
9. Are IPOs generally a good investment on the Nigerian Exchange?
They can be for patient, selective investors who treat them as ownership of a business rather than short-term trades. Historical evidence shows mixed results: some industrial and telecom names created significant long-term wealth, while many boom-period IPOs led to capital losses. Diversification, fundamental analysis, and avoiding over-allocation to any single new listing remain essential.
10. How can ordinary Nigerians participate in major IPOs like the Dangote Refinery offer?
Retail investors can apply through licensed stockbrokers, receiving banks, or digital investment platforms (many apps and bank portals supported the Dangote Refinery IPO). The minimum subscription was kept very low (just 10 shares / ₦5,250) to encourage broad participation. Investors need a valid Bank Verification Number (BVN), a CSCS account (or one will be created), and to complete the application before the offer closes. For help understanding the securities account requirement, read our guide on opening a CSCS account and getting a CHN. Always use only SEC-registered channels and read the prospectus carefully before applying.
