Africa's richest man has added $6.8 billion to his fortune in 2026 and is closing in on $40 billion

Aliko Dangote started this year at $30.4 billion. He is ending the first week of June at $36.8 billion, according to the Bloomberg Billionaires Index as of June 4, 2026. That is a gain of $6.8 billion in five months, a 22.7 percent increase that places him among the fastest-growing fortunes on the Bloomberg global ranking in 2026, not just in Africa but anywhere. The $40 billion threshold, which would have seemed speculative at the start of the year, is now a question of when rather than whether.

The pace of the appreciation has been striking even by the standards of a man whose wealth trajectory has consistently surprised forecasters. Three weeks into May, his net worth was $33.2 billion. A week later it was $34 billion. By May 11, it had crossed $35.9 billion. By June 4, Bloomberg had him at $36.8 billion. The weekly gains have been running at between $800 million and $1 billion at their most aggressive. In less than two weeks in early May alone, he added nearly $3 billion to his fortune. In the context of a $36 billion fortune, that is still extraordinary velocity.

He is 68 years old. He has described 2026 as the busiest period of his business life. Looking at what is actually on his plate, that is not an exaggeration.

The refinery that changed the calculation

Dangote's biggest single asset on the Bloomberg Billionaires Index is his 92.3 percent stake in the Dangote Petroleum Refinery, which Bloomberg values at approximately $20 billion based on the refinery's reported construction cost. That conservative methodology, which Bloomberg applies to private unlisted assets, means the refinery's contribution to his Bloomberg net worth has not yet captured the implied upward revaluation that its operational performance and pending IPO would demand.

The refinery's trajectory in 2026 makes the case for a higher valuation compellingly. It hit its nameplate capacity of 650,000 barrels per day in February. In April, S&P Global Commodities data confirmed it had become the world's single largest exporter of jet fuel, capitalising on Middle East supply disruptions to supply aviation fuel to Europe, the United States and as far as Saudi Arabia. In June, process licensors certified a test performance of 700,000 barrels per day, surpassing the nameplate capacity the facility was designed for. Jet fuel exports surged 770 percent between 2024 and 2026. The refinery has done in 24 months of operation what successive Nigerian governments and oil sector reform programmes failed to do over 60 years: eliminate Nigeria's dependence on imported petroleum products.

Now the refinery is preparing to go public. The Dangote Petroleum Refinery and Petrochemicals IPO is targeting a valuation of $40 billion to $50 billion and an offering of between 5 and 10 percent of the company's equity. At $50 billion and a 10 percent stake, the implied offering size is $5 billion. No African stock exchange has ever hosted an offering of that scale. The largest IPO ever conducted on the Nigerian Exchange raised approximately $500 million. The refinery IPO, if it closes at its target valuation, is ten times that and would be the largest IPO on any African bourse in the continent's history.

The prospectus was submitted to Nigeria's Securities and Exchange Commission in April 2026. Regulatory review is underway. A national investor roadshow is planned for the June to August period. The subscription window is expected to open in August 2026. Advisers Stanbic IBTC Capital, Vetiva Capital Management and FirstCap have been formally appointed and are working on the transaction structure.

The financial structure carries a feature that is almost unprecedented in Nigerian capital markets. Dangote has proposed that shares be purchased in naira but dividends be paid in US dollars, backed by the refinery's substantial export earnings. That dollar dividend structure, pending final regulatory approval from Nigeria's SEC, is specifically designed to attract international investors who would otherwise be deterred by the naira's currency history. If it clears approval, it gives the offering a return profile that no Nigerian listed company has ever provided.

The pan-African ambition goes further. The primary listing is targeted at the Nigerian Exchange Group main board, but the Dangote Group has already convened meetings with executives from multiple African stock exchanges, including the Kenya Stock Exchange, to discuss simultaneous secondary listings. The goal is to structure what would be the first genuinely pan-African IPO in the continent's history, with shares tradeable across multiple sovereign jurisdictions simultaneously. A secondary listing on the London Stock Exchange is also under review. When Bloomberg eventually marks up its refinery valuation from construction cost to anywhere near the $40 billion to $50 billion IPO target, the effect on Dangote's total Bloomberg net worth figure would be immediate and very large.

Dangote Cement and the London ambition

Running alongside the refinery story is Dangote Cement, which has been one of the best-performing large-cap stocks in Africa in 2026. Shares of the NGX-listed cement giant have gained nearly 70 percent since March 2025. The company reported a profit before tax of N421.1 billion for the first quarter of 2026, a 35 percent year-on-year jump, on revenue of N1.19 trillion. Full-year 2025 profit before tax came in at N1.53 trillion, a 109 percent increase on 2024, representing the most profitable year in the company's history.

Dangote Industries holds approximately 86 percent of Dangote Cement's issued share capital. As the share price has climbed, the naira value of that stake has risen proportionally, and a strengthening naira has added a dollar translation bonus on top of the underlying share price gains.

Now Dangote Cement is also heading for London. The company is targeting a secondary dual listing on the London Stock Exchange by September 2026, after 15 years of exploring and abandoning the idea. The barrier was always the LSE's listing requirements, which Nigerian companies found expensive and burdensome to meet. The UK Financial Conduct Authority changed that with a sustained overhaul of listing rules designed explicitly to attract more international companies and reverse London's declining competitiveness relative to New York.

"We want to do a dual listing. We've been thinking about it for seven to ten years," Dangote told the Financial Times in May. He added that the FCA reforms had revived his confidence in the London option. The target is September 2026, subject to regulatory approvals, market conditions and investor demand. Approximately 10 percent of Dangote Cement's shares would be sold to outside investors as part of the process. Dangote Cement issued a formal statement on May 12 confirming that discussions are underway but that no final decision has been made on structure, timing or terms.

What a successful London listing would deliver is straightforward to describe and difficult to overstate. Dangote Cement would become eligible for inclusion in global equity indices tracked by the passive funds that collectively manage tens of trillions of dollars. Institutional investors in Europe and North America who currently have no route to Nigerian equities exposure would have a liquid, London-regulated entry point. The company's valuation benchmark would shift from a Nigerian Exchange context, where the investor pool is constrained, to a global one, where comparable cement and materials companies trade at significantly higher multiples. The arbitrage between those two valuations is part of what Dangote is trying to unlock.

The global ranking trajectory

Dangote began 2026 ranked approximately 80th on the Bloomberg global billionaires list. By early May he had climbed to 65th. As of June 4, his $36.8 billion places him at 65th globally and comfortably ahead of every other African billionaire. Johann Rupert, Africa's second wealthiest, sits at approximately $18 billion. The gap between first and second on the African ranking is larger than it has ever been.

The Bloomberg methodology remains conservative on Dangote's private assets. The refinery is valued at construction cost, not at the $40 billion to $50 billion that Dangote and his advisers are targeting for the IPO. The fertiliser subsidiary, with capacity to produce up to 2.8 million tonnes of urea annually, is also carried at a conservative private asset figure. When these businesses reach public markets, the gap between Bloomberg's current estimate and the implied market valuations will be forced to close, and the closing of that gap is the single most powerful catalyst for pushing his net worth past $40 billion.

What the $40 billion threshold would mean

No African has ever been worth $40 billion. The threshold would place Dangote comfortably among the world's 50 richest individuals, in the same wealth bracket as Larry Ellison, Steve Ballmer and Mukesh Ambani. It would represent the most dramatic single-year wealth creation story on the African continent since Forbes and Bloomberg began systematically tracking African billionaire fortunes.

The catalysts that could get him there are visible and near-term. The refinery IPO, if it prices at or near the $50 billion target valuation, would force Bloomberg to mark up its private asset estimate, potentially adding $10 billion or more to the Bloomberg figure in a single event. Continued Dangote Cement share price appreciation ahead of the London dual listing adds incrementally each week. Expansion of refinery capacity toward the 1.4 million barrels per day target strengthens the operational case for a higher standalone valuation every time a new production milestone is certified.

He started 2026 at $30.4 billion. He is at $36.8 billion today. Two landmark capital markets transactions are in preparation simultaneously. The refinery is producing above nameplate capacity and exporting to four continents. The cement company is heading for London. The fertiliser plant is the largest of its kind on the continent. The $40 billion question is not whether. It is what triggers it and when.
